Introduction

Fresh blueberries are a nutritious option for a vegan diet, providing antioxidants, vitamins, and fibre. Including them in your daily meals may support overall health and well-being.

A vegan diet is associated with plants such as grains, nuts, fruits, and vegetables. Individuals who follow a vegan lifestyle do not eat any food that comes from animals, including eggs and dairy products (The vegan diet, 2022).

Key Elements of a Healthy Vegan Diet

A healthy vegan diet includes:
  • 5 portions of fruits and vegetables each day.
  • Starchy carbohydrates such as rice, pasta, and potatoes, ideally whole grains where possible.
  • Choose lower-fat and lower-sugar options by consuming fortified dairy alternatives such as yoghurt substitutes and soya drinks.
  • Pulses, beans, and other protein sources.
  • Nuts and seeds rich in omega-3 fatty acids, such as walnuts.
  • Use small amounts of olive oil
  • Drink plenty of fluids, up to 2 litres per day.
  • Key elements such as vitamin D, vitamin B12, iodine, selenium, calcium, and iron.

The Effect of Healthy Vegan Diets

Vegan diets are usually higher in vitamins C and E, folic acid, and magnesium, and lower in calories, cholesterol, and saturated fat. Experts suggest that vegetarians and vegans may have a lower risk of cardiovascular disease, type 2 diabetes, obesity, and certain cancers (Craig, 2009).

Plant foods, especially fruits, vegetables, and whole grains are linked to reduced risk of chronic diseases such as colorectal cancer and type 2 diabetes. According to Fraser, vegans also tend to have lower total cholesterol and blood pressure.

To maintain a nutritious vegan diet, individuals must understand proper food balance. Vegans are known for consuming vitamin C-rich foods, which improve the absorption of non-heme iron. However, vegans may face a higher risk of vitamin B12 deficiency and elevated plasma homocysteine levels.

Vegetarians may also have lower zinc intakes, although functional immunity shows little difference compared to non-vegetarians.

Veganism is not just a diet but a lifestyle choice that avoids all animal products. Vegans are encouraged to consume B12-fortified foods such as rice beverages, fortified soy, and breakfast cereals, and to include plant foods rich in omega-3 ALA, including canola oil, soy products, ground flaxseeds, and walnuts. Unlike vegetarians, who may still consume dairy, eggs, or honey, vegans completely avoid them.

The Effect of Vegetarian Diets

Vegetarians do not consume meat, poultry, or fish. Both vegetarians and vegans can vary their diets. India has over 35% of its population following a traditional vegetarian diet (Key, Appleby & Rosell, 2006). In the UK, around 5% of people identify as vegetarian. While vegans strictly avoid all animal products, vegetarians consume dairy and eggs.

Types of Vegetarian Diets

  • Lacto Vegetarian: Includes dairy products like cheese and milk, but excludes meat, seafood, or eggs.
  • Ovo Vegetarian: Includes eggs but avoids dairy, meat, and seafood.
  • Lacto-Ovo Vegetarian: Includes dairy products and eggs but avoids meat and seafood.

Historical Perspective on Vegetarianism

Vegetarianism has deep historical roots. Ancient Greek thinkers believed animals shared similarities with humans, making it morally wrong to harm them. They saw plant-based diets as purifying for the soul and beneficial for mental clarity. During the Renaissance, philosophers, including Leonardo da Vinci, predicted a future in which eating animals would be viewed as cruel as eating humans. The modern era saw thinkers such as Tyron, Rousseau, Voltaire, and Wesley promote vegetarian diets for ethical or economic reasons.

The modern vegetarian movement began in 1847 with the founding of the Vegetarian Society of the United Kingdom in Ramsgate, Kent.

Although later, the Vegan Society (1944)  was established in Leicester. Influential advocates such as Sylvester Graham, Harvey Kellogg, and Maximilian Bircher-Benner contributed to the promotion of plant-based nutrition. Prominent advocates such as  George Bernard Shaw, Mahatma Gandhi, Albert Schweitzer, and Albert Einstein further promoted vegetarianism for moral and humanitarian reasons.

Mahatma Gandhi (1869–1948) once said, There is enough for everybody’s feed, but not enough for everybody’s greed.

Albert Einstein, the German-US physicist (1875–1955), said that Nothing will increase the chances of survival for life on earth as much as the evolution to a vegetarian diet

Albert Schweitzer, a German physician, said: We must renounce meat consumption and speak up against it. (Leitzmann, 2014).

Vegetarian Nutrition in Recent Years

In recent decades, vegetarianism has gained global popularity for health, ethical, and environmental reasons. Despite this, vegetarians remain a minority in most countries, with India being an exception. The following table presents data from various vegetarian societies and censuses:

Country Population (Million) Vegetarians (Million) % of Population
India126045035%
Italy615.99%
Great Britain635.49%
Germany827.49%
Netherlands170.74%
United States32012.14%
Canada351.34%
Austria80.253%
Switzerland80.233%
France641.22%

Western countries are gradually reducing meat consumption, with Germany showing a 10% drop. Nutrition education now focuses on promoting awareness of balanced diets and preventing nutrient deficiencies.

1. Motivation for Nutritional Balance

Motivation plays a crucial role in how vegetarians manage their diet. Health-motivated vegetarians are more likely to plan balanced meals and monitor nutrient intake. Ethically motivated vegetarians, on the other hand, may focus less on imbalances due to a limited focus on nutrition.

2. Nutrient Loss and Food Processing

Vegetarians aim to maintain nutrient-rich diets. However, refining grains into products such as white flour may sometimes remove key nutrients. Whole-grain products such as pasta and bread may help reduce cholesterol and lower the risk of digestive tract cancers due to higher fibre content.

The Importance of Raw Foods

Raw foods preserve natural nutrients and promote better digestion, satiety, and bowel health. They also encourage chewing, which supports oral health and saliva production. The German Nutrition Society recommends consuming at least 100 grams of raw foods per day.

Conclusion

A vegan or vegetarian diet may support overall health when it is balanced and properly structured. Both approaches are linked with higher intake of plant-based nutrients, including fibre, vitamins, and antioxidants, while often being lower in saturated fat and cholesterol. Research also suggests potential benefits may be for long-term health outcomes, such as reduced risk of certain chronic diseases.

However, attention to key nutrients, including vitamin B12, iron, iodine, calcium, and omega-3 fatty acids, is crucial to avoid deficiencies. With structured food choices and appropriate supplementation when needed, plant-based diets may be nutritionally adequate and sustainable.

Overall, vegetarian and vegan diets are not only dietary choices but also lifestyle patterns that continue to gain global interest for health, ethical, and environmental reasons.

Exercises for Cardio: Evidence-Based Approaches to Cardiovascular Health

  February 16, 2026 Xhavid Bajrami   

Introduction

Physical activity refers to the movement of the body produced by skeletal muscle contractions. Exercise is a specific form of physical training that is intentionally goal-directed, organised and planned to improve physical fitness. 

Physical fitness is the ability to perform everyday activities effectively without excessive fatigue, while maintaining sufficient energy to respond to unexpected training demands and to enjoy leisure activities.

Physical exercises can be dynamic (isotonic), involving movement, or static (isometric), where muscle contraction occurs without visible joint movement. They can also be categorised into concentric actions, muscle fibres shorten and lengthen, including a load contrary to gravity. Some of the exercises can be categorised based on metabolic demand as aerobic, taking place in the presence of adequate oxygen. 

Most physical training involves both static elements and dynamic elements. Isometric exercises mainly focus on pressure overload, and dynamic aerobic exercises focus on a volume load on the heart. Both of them are important for cardiovascular health.

Regular training improves aerobic ability and contributes to better heart and lung function. International clinical guidelines strongly recommend regular exercise as an effective non-pharmacological method for cardiovascular disease prevention (Zachariah and Alex, 2017).

What are the Benefits of Exercise for Cardiovascular Health?

A physically inactive lifestyle is acknowledged as one of the five leading risk factors for heart disease, along with high blood pressure, obesity, smoking, and unhealthy lipid levels.

Scientific research indicates that lowering these risk factors remarkably reduces the likelihood of having a heart attack or bypass surgery. Regular physical activity can positively affect many cardiovascular risk factors. Exercise helps with weight loss, lowers blood pressure, reduces levels of low-density lipoprotein (bad cholesterol) and total cholesterol, and increases high-density lipoprotein (good cholesterol). 

Individuals with diabetes who engage in regular physical activity improve how the body uses insulin efficiently, aiding blood glucose control.

Moderate activity can reduce cardiovascular risk when combined with other healthy lifestyle choices, including quitting smoking, balanced nutrition, and using appropriate medication. Regular exercise increases muscle function and strength, and improves oxygen intake (aerobic capacity). It can also increase vascular function, benefit bone health, reduce the risk of disability and back pain, and improve the performance of daily activities. 

People newly diagnosed with heart disease who engage in regular exercise often report returning to work sooner, feel self-confident, and have a better quality of life. Major public health guidelines recommend at least 30 minutes of moderate-intensity exercise per day, such as walking approximately 4.8 to 6.4 kilometres (Myers, 2003).

Fitness Prescription for Weight Management and Cardiovascular Training

Exercise recommendations for improving cardiorespiratory fitness and managing body weight are determined by training frequency, duration, and intensity. Aerobic exercise seems to be the main contributor to aerobic focus. 

Studies show that 6–12 months of consistent training may improve fitness. Improvements in maximum oxygen uptake (V̇O₂max) are closely linked with exercise intensity, frequency, and duration, usually increasing 10–30%. 

Those with low baseline fitness levels can achieve greater improvements. Training duration and intensity are critical; higher intensity may also increase injury and heart risk. A balance between moderate and longer sessions is usually best, with at least 10 minutes being effective. Longer duration and moderate intensity are highly recommended for most adults (Garber et al., 2011a).

Role of Exercise in Lowering Inflammation Through Epicardial Fat

Ectopic fat is fat storage of triglycerides in tissues not mainly designed for fat deposition, including skeletal muscle, visceral depots, the liver, and myocardium. Epicardial fat is associated with visceral obesity, elevated triglycerides, insulin resistance, features of embolic syndrome, and increased blood pressure. 

It is also linked to left obesity, higher blood pressure, and high triglycerides (Golbidi and Laher, 2012).

Fat tissue acts as an endocrine organ; it releases chemicals, including leptin, TNF-α, IL-6, and MCP-1. 

Aerobic exercise significantly reduces epicardial and visceral fat, often exceeding changes in total body weight and BMI. Regular physical activity reduces visceral and epicardial fat. It also decreases inflammation in the body (Golbidi and Laher, 2012).

Cardiovascular Role of Heat Shock Proteins (HSPs)

The heat shock response is a cellular defence mechanism and is activated when the body is under stress, such as hypoxia, protein damage, oxidative stress, ischemia, energy depletion, and elevated intracellular calcium. Exercise stimulates heat shock protein expression in cardiac tissue, though mechanisms remain incompletely understood (Golbidi and Laher, 2012).

Categories of Physical Activity and Intensity

Daily activities beyond organised sports, including stair climbing, brisk walking, chores, gardening, and active leisure, contribute to health benefits. Exercise intensity can be measured via oxygen consumption (mL/min) or metabolic equivalents (METs). 

One MET equals the resting metabolic rate (3.5 mL/kg/min). Activities 3–6 METs are moderate (Zachariah and Alex, 2017).

Absolute intensity does not consider age, sex, body mass, or fitness. Relative intensity, measured as a percentage of VO₂max or heart rate reserve, accounts for these differences and is particularly important for older adults (Valenzuela et al., 2023).

Exercises That Increase Muscular Fitness

Muscular fitness improves through resistance training using free weights, machines, or elastic bands. Programs should include dynamic movements with both eccentric (lengthening) and concentric (shortening) contractions, including shoulders, back, hips, legs, trunk, arms, and chest. 

Single-joint exercises include abdominals, calves, lumbar extensors, hamstrings, biceps, and quadriceps. Training opposite muscle groups prevents imbalances. Proper technique, full range of motion, and proper breathing  , such as inhale eccentric, exhale concentric, are essential (Garber et al., 2011b).

Cardiovascular Risk: An Evolving Therapeutic Approach

Lowering LDL-C reduces coronary heart disease (CHD) risk. Combining LDL-C reduction with increases in HDL-C leads to better clinical outcomes. This approach can be used by clinicians to support reverse cholesterol transport in appropriate patient groups (Superko and King, 2008).

Conclusion

Regular physical activity brings profound benefits for cardiovascular health, from reducing inflammation and managing weight to improving cholesterol and blood pressure. Furthermore, exercise alone can not replace medical treatment; it is an evidence-based tool for preventing heart disease. Adopting a regular routine including aerobic, resistance, and flexibility training may significantly enhance both longevity and quality of life.

Chronic Inflammation: Lifestyle-Based Management, Causes, and Effects

  January 15, 2026 Xhavid Bajrami   

Introduction

bowls of fruits and almond

In medical conversation, the term inflammation is often misunderstood, and the concept dates back to Roman times. 

Inflammation is e viewed by many people as something malfunctional or harmful, and it is frequently forgotten that inflammation is crucial for survival and health. 

The word Inflammation is an old word that comes from the Latin “inflamare”, meaning to set alight or burn. 

It is important to know how the body responds to any possible threats. Inflammation is intended to protect the body, act fast and settle down when the threat is gone.  

In the last few decades, advances in molecular biology have expanded this understanding. It is now better understood for both processes of involving immune and non-immune cells, triggered by factors such as toxins, infections, cellular damage, and radiation.  The main goal is to balance and maintain normal function within the body (Oronsky, Caroen and Reid, 2022).

Chronic Inflammation that matters today

Short-term inflammation is important for survival in response to injury and infection. Although studies show that social, lifestyle, and environmental factors may lead to chronic systemic inflammation.

This persistent inflammatory state contributes to the multiple circumstances that are responsible for a large part of global illness and death. These involve:

  • Heart disease, 
  • Cancer, 
  • Chronic kidney disease,
  • Non-alcoholic fatty liver disease,
  • Neurodegenerative diseases.

This article explores biological mechanisms operating at multiple levels that support systematic chronic inflammation and examines components that increase risk, including infections, unhealthy dietary patterns,  and psychological stress. It also explores  early prevention, detection, and management of SCI (Furman et al., 2019).

Immunosenescence and ageing of bone marrow determined by hematopoietic stem cells. Bone marrow is the main location of blood cell formation, and it represents a highly dynamic place in skeletal cells, stromal elements and hematopoietic populations. 

Older bone marrow is the accumulation of important changes. These aged stromal cells show molecular hallmarks of senescence, such as:

  • Genomic instability, 
  • Excessive reactive oxygen species production, 
  • Raised expression of senescence-associated secretory phenotype (SASP).

The inflammatory environment created by SASP disrupts healthy cells, altering gene expression in surrounding healthy mesenchymal cells. Ageing of the bone marrow is associated with several issues, such as:

  • haematological abnormalities, 
  • increased rates of anaemia, which may weaken the adaptive immune system
  • the larger the risk of myelodysplastic syndromes
  • myeloproliferative diseases. 
Functional remodelling of bone tissue may worsen hematopoietic decline. As we get older, active red marrow is progressively replaced by adipose tissue, which creates yellow marrow that restricts blood cell production. Older hematopoietic stem cells show an increased tendency to generate myeloid cells and decreased ability to support immune cell development.

The number of hematopoietic stem cells can rise with age, but other aspects, such as clonogenic potential and self-renewal, functional quality, and clonogenic potential, decline distinctly with SCI (Furman et al., 2019).

T-cell immune competence and Thymic aging

The thymus is crucial for the generation of immune T-cells, which are important for immune defence and immune tolerance. T-cell production and thymic hormone production are highest in early in life and gradually decline thereafter (Li et al., 2023). 

Studies show that ageing in the thymus is associated to:

  • Oxidant stress,
  • DNA damage, 
  • Increased phosphorylation of p53. 
These molecules encourage cellular senescence and support the concept that the ageing thymus becomes gradually improved with senescent cells.

Chronic Inflammation as a Driver of Disease

Chronic inflammation often occurs without obvious symptoms and plays a major role in long-term diseases. It can affect both lifespan and quality of life. 

Many external and internal factors contributing to the maintenance of this inflammatory state, including:

  • Tobacco use, 
  • Ageing, 
  • Dietary habits, physical inactivity, 
  • Excess body weight, 
  • Psychological stress, 
  • Hormonal changes,  
  • Disrupted wake and sleep cycles.

Furthermore, fat tissue is characterised by an inflammatory environment with immune cell infiltration and releases inflammatory substances of adipose tissue and strengthened cytokine release. These procedures contribute to metabolic disorders and insulin resistance.

Among adaptive and innate immune mechanisms, adipose signalling molecules play a crucial role in the inflammatory state (Chavda, Feehan and Apostolopoulos, 2024).

Mediterranean-style eating, inflammation, and vascular health inflammation

The Mediterranean dietary model was described by Ancel Keys in the mid twentieth century, and it is characterised by: 

  • Extra virgin olive oil, 
  • Fruit and vegetables, 
  • Legumes, 
  • Whole grains, 
  • Low-fat dairy products,
  • Fish 
  • Small amount of red meat 
According to experts, Mediterranean diets lower several cardiovascular risk factors in primary prevention settings (Schwingshackl and Hoffmann, 2014).

Anti-inflammatory properties of curcumin and Antioxidant

Curcumin is a bioactive compound derived from turmeric. It has been widely researched for its antioxidant and anti-inflammatory properties. 

Research shows that curcumin may promote a wide variety of beneficial biological activities, especially in regulating oxidative stress and inflammatory responses, (Lu and Yen, 2015). Various studies have shown that tea catechins, mainly present in green tea and other dietary sources, contain multiple bioactive combinations. Along with these, epigallocatechin gallate is well-known as one of the most effective and potent catechins.

Carotenoids are widely known for their promoting quality and their role in supporting human well-being. Although astaxanthin, on the other hand, is a structurally distinct carotenoid that has been well studied for its diverse biological activities (Lu and Yen, 2015).

Diet, Its Role in Inflammation and Chronic Disease Risk

Dietary intake represents one of the most important modified influences. 

The evidence shows:

  • Mediterranean dietary pattern is associated with a reduction in inflammatory markers,  
  • A diet rich in added sugar 
  • Trans fats are linked directly to increased inflammatory response. 
  • Saturated fats have been associated with elevated and correlated inflammatory biomarkers. 

Dairy foods play an important role in healthy eating patterns, such as the Dietary Approaches to Stop Hypertension diet. According to the DGA, individuals age nine and older are recommended to consume three cups or equivalents of low-fat or fat-free dairy products daily. 

Consuming dairy products is rich in nutrients, such as:

  • Vitamin D, 
  • Calcium, 
  • Vitamin B12, 
  • Protein, 
  • Zinc, 
  • Potassium, 
  • Magnesium 
  • Selenium.

Dairy has been identified as one of the main dietary sources. It has been associated with positive health results, which will result in reducing the risk of cardiovascular disease, type 2 diabetes, supporting bone health and metabolic syndrome. 

Additionally, dairy products are recognised as containing pro-inflammatory components, such as saturated fat and lactose content. 

As a result, the importance of consuming dairy for achieving nutritional adequacy, while reducing the risk of chronic disease,is noted  (Nieman, Anderson and Cifelli, 2021).

Conclusion

Chronic inflammation is a major health problem that can affect many people around the world. Short-term inflammation helps protect us from injury and infection, but long-term inflammation can silently damage the body. This increases the risk of serious diseases such as heart disease, diabetes and cancer. 

Many everyday factors can lead to this condition, including poor diet, lack of exercise, stress, smoking, and not getting enough sleep.

The good news is that chronic inflammation can often be managed through simple lifestyle changes. Eating a balanced diet, especially one similar to the Mediterranean diet, can help reduce inflammation.

This includes, for example, eating more fruits, vegetables, whole grains, healthy fats such as olive oil and fish, while limiting processed foods, sugar and unhealthy fats. Natural compounds such as curcumin and antioxidants commonly found in foods such as green tea can also support the body in reducing inflammation.

In addition, staying physically active, maintaining a healthy weight, managing stress, and having good sleep habits are all important steps in controlling inflammation. As the body ages, the immune system may become less effective, which makes these healthy habits even more important.

In conclusion, chronic inflammation is influenced by many factors overall, but it can also be controlled with the right choices. By making small, consistent lifestyle changes, individuals have an opportunity to improve their overall health, reduce their risk of disease, and support a better quality of life.

How Food and Nutrition May Support Respiratory Health

  December 08, 2025 Xhavid Bajrami   

Introduction

Bowl of apples, oranges and almonds

Asthma is a paroxysmal syndrome that affects the respiratory system, characterised by severe breathing difficulty. These episodes are often described as a tight feeling across the chest and a heavy feeling of imminent suffocation, happening in the absence of fever or limited inflammation. 

In many cases, asthma or an asthmatic episode is often followed by several days of symptoms related to gastrointestinal disturbance. These can include: 

  • The symptoms are reduced appetite, 
  • Acid regurgitation, excessive hunger, 
  • Abdominal bloating, 
  • Heartburn, 
  • A feeling of pressure over the eyes, 
  • Anxiety in the precordial area, and 
  • Skin itching. 
Asthma attacks usually begin at night during night sleep. The signs of Asthma are characterised by chest tightness, anxiety, difficulty breathing, and a dry, short cough. Breathing becomes heavy, gasping, laboured, and suffocative, while the facial expression reflects extreme discomfort and apprehension. Irregular heartbeat is present. 

The patient always demands that doors and windows be left open, and the need for fresh air becomes overwhelming. There is also an increase in the need to move from bed to an open window, and the patient finds it difficult to remain in a lying position. The pulse may look frequently irregular.

Asthma commonly develops in childhood, but it can occur at any age.  Is also influenced by a complex mix of genetic, environmental, and predispositional influences and is often linked to different symptoms. 

Asthma researchers continue to identify the risk of different models on individual risks of asthma. Healthcare professionals diagnose asthma through a combination of patient history, lung function testing, physical examination, and relevant lab work. 

Many treatments focus on continuous patient education, regular symptom management treatment, and quick relief inhalers when required(Varraso et al., 2007).

Immune Responses, Respiratory Health and Dietary Fat Intake

Studies show that the relationship between the immune system and immune systems. Researchers suggest that consuming high-fat diets may trigger inflammatory responses in the body.

High-fat diets have been associated with elevated levels of pro-inflammatory markers, such as neutrophils and cytokines. Therefore, these changes may negatively affect lung function and contribute to inflammation of the airways, such as asthma.

Both of these were examined, such as the expression of Toll-like receptor 4 (TLR4) and also higher neutrophil concentration was discovered in the sputum of patients with asthma after eating fat-rich foods.
In addition, the findings show that immune mechanisms contribute to inflammation and respiratory complications(Wypych, Marsland and Ubags, 2017).

The Role of Diet and Nutrients in Asthma Food Control

Researchers have identified how diet influences asthma risk, focusing on both dietary patterns and nutrients. Dietary pattern analysis examines how individuals consume food, including its frequency, combinations, and diversity. 

These nutrients are consumed as part of a complex food matrix, and this approach offers important advantages when studying the relationship between diet and health. 

Therefore, the most frequently studied dietary patterns include the Mediterranean diet. The Mediterranean diet emerged in the 1950s and 1960s in the seacoast regions of southern Europe, particularly in Greece and Italy. This diet has been linked to a lower rate of heart disease. 

The guidelines for the Mediterranean diet highlight meals rich in vegetables, fruits and whole grain cereals. Vitamin D intake during pregnancy has been linked to a reduced risk of childhood wheezing. Despite these findings, researchers have shown that neither vitamin D nor vitamin E intake has been clearly demonstrated to have a consistent effect on the development of childhood asthma(Guilleminault et al., 2017).

Although no particular recommendations to prevent asthma during pregnancy have been discovered,   the guidelines for vitamin D  should be followed by respiratory medicine specialists.

The Beneficial Effects of Fruits and Vegetables

Clinical respiratory researchers suggest that consuming fruits and vegetables appears to be associated with a lower risk of Asthma. Consuming vitamin C at a dose of 0.2 g per day has demonstrated modest improvement in Asthma control. 

Vitamin D can significantly reduce the risk of asthma exacerbations among school-aged children. Therefore, vitamin D supplementation in preschool-aged children has not shown a significant impact on subjective asthma control and needs further clinical trial research (Guilleminault et al., 2017).

Minerals for Respiratory Health

Some minerals have an important role in respiratory health, particularly in children. 

Higher intake of calcium, magnesium and potassium has been associated with a lower incidence of asthma. Although due to the high number of experimental studies, the observations have been inconsistent, findings indicate that reduced dietary sodium did not improve bronchial responsiveness in adults with asthma. 

Magnesium has been viewed as a bronchodilator in asthma. Low dietary magnesium is linked to harm to bronchial smooth muscle function in severe asthma and reduced lung function in children.  

According to experts, Selenium intake has been considered to be lower among individuals with asthma. Higher maternal plasma selenium concentrations have been inversely associated with asthma risk in the outcome. 

Other studies show that in large, well-controlled trials, selenium supplementation has not shown any sagnificant  benefits.  Furthermore, minerals tend to influence respiratory health, and the evidence does not support supplements(Berthon and Wood, 2015).

Medical Plants for Respiratory Disease Treatment

Herbal medicine commonly used to treat respiratory disorders indicate a wide range of biological activities, such as: antiallergic, immunomodulatory, and anti-inflammatory, antioxidant and also antiviral effects. 

Although people suffering from respiratory health conditions, including cold, cough, bronchitis, and asthma, are largely on plant-based remedies. 

The benefits of herbal treatment may help relieve symptoms through multiple mechanisms:

  • Anti-inflammatory combinations reduced disease severity.
  • Antiallergic agents prevent pathogen-induced allergic responses.
  • Immunomodulators build up host immune defences.
  • Antioxidants counteract free radicals at sites of infection.
  • Antimicrobial properties may help to limit respiratory pathogens.

The remarkable expertise of plants to provide novel bioactive combinations is reflected in the global pharmaceutical market. Medical plants represent more than half of all medical products in the medical world. 

In the world, approximately 80% of the population relies on traditional plants based on traditional therapies for primary health care. The support has also come from the World Health Organisation, which encourages the consolidation of traditional and modern medicine, while supporting the integration of medicinal plans. 

Herbal remedies are well known for demonstrating favourable, toxicological, pharmacological and clinical profiles. Several plants are well documented in ethnomedicine, such as thyme, peppermint, eucalyptus, liquorice root, ginger, and turmeric, and those are supported by clinical and pharmacological evidence(Idreis, 2025).

Thyme

Thyme is a therapeutically and nutritionally valuable herb that has been used in ancient times for both culinary and medical purposes. Its essential oils and spices contain compounds with antibacterial, antispasmodic, expectorant, antifungal, and antioxidant properties that contribute to respiratory health.

Peppermint

Peppermint belongs to the Lamiaceae family.  It is a fast-growing perennial herb and rich in menthol and essential oils. Peppermint oil is widely used in cosmetics and pharmaceutical industries, because of  its antiseptic, analgesic, antipruritic, anti-inflammatory and antimicrobial activities.

Liquorice Root

Liquorice Root continues to play a crucial role in treating respiratory disorders and as a supplement to conventional therapies. It is often used for inflammatory and infectious conditions and neurodegenerative diseases.

Ginger

Ginger is a valuable rhizomatous herb, and it is used for medicine and food. Ginger was first used in southern Asia, and it is widely used in the kitchen. It may help to manage gastrointestinal disorders, metabolic diseases, inflammatory ailments and cardiovascular conditions.

Turmeric

Turmeric is used for many treatments, including conditions of the lower and upper respiratory tracts and for its anti-inflammatory properties. Its expectorant action helps in the removal of mucus from the respiratory passages, and it reduces congestion, linked with respiratory infections(Idreis, 2025).

Indoor Humidity for Asthma Prevention

Fungal spores and dust mites are extremely significant. The relative humidity is maintained below around 45% at temperatures of 20-22 °C, where under these conditions house dust mites are difficult to survive. 

Although clinical research indicates that higher humidity levels promote a rapid rise in mite populations, this contrast means reaching a few thousand mites per gram of household dust. Increased indoor humidity also supports fungal growth. 

Approximately 60% of identified cases may be linked to house dust mites. Preventive methods may include increasing ventilation and reducing the moisture generated indoors. 

Ventilation should be easy and flexible, but not fixed, and therefore, all humidity levels should always be controlled. Higher humidity levels may lead to a rapid increase in mite populations and may also encourage fungal growth (Andersen and Korsgaard, 1986).

Short-Chain Fatty Acids (SCFAs)

Short-chain fatty acids (SCFAs) can be picked up from certain foods, including some of the cheeses, butter, and cow milk, and these are at a point produced through the fermentation of complex bacterial polysaccharides present in dietary fibres. 

Short-chain fatty Acids have been examined for their inflammatory effects in vitro.  Short-Chain Fatty Acids and high fibre diets have been recognised to reduce inflammation in animal models of diseases, including peanut allergy, airways inflammation, colitis, and allergic airways inflammation. 

The procedures through which Short-Chain Fatty Acids exert their effect are varied. Short-Chain Fatty Acids can contribute to regulatory T helper cells, and decrease the capability of dendritic cells to activate effector T cells and start the inflammasome.

Pro-inflammatory is generally considered both Saturated and omega-6 polyunsaturated fatty acids (Wypych, Marsland and Ubags, 2017)

pH Regulation, Dietary Influences, and Health Evidence

  November 10, 2025 Xhavid Bajrami   

Introduction

Fresh juice ingredients including oranges, lemon, ginger and green leaves

Maintaining the body’s acid-base balance is an important aspect of overall health. 

Even a small change in body fluid pH indicates that it can affect cellular functions, enzymatic reactions and overall homeostasis. 

Body fluid pH  indicates the concentration of hydrogen ions (H+), which is generated from different metabolic processes. Organic acids, including β-hydroxybutyric acid and lactic acid, are generated in tissues such as the liver, adipose tissue, and skeletal muscle. 

These acids separate into protons and conjugate bases, and that leads to acidification of intracellular and extracellular environments. The human body uses many buffering systems and transport mechanisms.

The major contributions of the buffering system involve proton-proton binding, the bicarbonate system and phosphoric acid buffering, and this stabilises pH by neutralising excess protons. Cells use a special transporter system for moving extra protons out of the cell into the space around them, including monocarboxylate transporter MCTs and Na+/H+ exchangers (NHEs). 

These procedures allow for maintaining a normal internal pH at a normal level around 7.03-7.46, and that is crucial for healthy metabolism. Therefore, when cells are affected by too much acid, the problem arises with the transporter, and normally, the fluid around the cells may become more acidic.

According to experts, a lower pH in the fluid between cells, may contribute to metabolic problems, for example, in insulin resistance, obesity and type 2 diabetes. Furthermore, food can improve proton transport and also support metabolic health (Aoi et al., 2020).

Understanding pH

Alkaline acid has to do with pH. The meaning of pH refers to how acidic or alkaline something is, such as:

  • It is considered acidic when the pH is low (between 0 and 6). 
  • High value on  the pH scale (from 8 to 14) is considered alkaline. 
  • 7 is considered neutral. 
Understanding food better shows that some foods contain alkaline and others are acidic. For example, citrus fruits such as lemon, grapefruit, and oranges are acidic foods. The acidic food we consume over time can change the pH level in our blood. 
The reaction occurs continuously through our breath, with a chemical signal, through the brain, and the kidneys work hard to regulate pH through large and small adjustments (Henry, 2019). According to studies, the more you consume acidic food, the harder your body will work, and this can have long-term effects.

The concept of Alkaline and Acid comes from human practice. The meaning of acid comes from the Latin word acere, which means sour. Acid tests have a sour taste, observed from foods like sour milk, lemon juice, and vinegar. 

The word Alkaline is an Arabic word al-qily, which refers to burnt plant ashes. The terms acids and bases began in 1776 with Antonio Lavoisier. In 1838, Justus von Liebig declared acids as substances that contain hydrogen. Later, Sørensen, a Danish scientist, introduced the concept of pH at the Carlsberg Laboratory, updated in 1924 based on modern electrochemical methods.

Ancient Indian texts like Hatha Yoga Pradipika, Shiv Samhita, and Gheranda Samhita studied food effects on the body and classified it as sattvic (pure), rajasic (stimulating), and tamasic (heavy/impure). 

Charak (~200 AD) in Charak Samhita classified foods as light or heavy; light foods were recommended for good health. E.V. McCollum (Johns Hopkins) recommended more alkaline-forming foods like vegetables, grains, milk, fruits, butter, and cheese. 

Blood pH should be between 7.35 and 7.45. Small pH changes affect organisms, like oceans dropping from 8.2 to 8.1 due to CO₂, harming coral reefs. Soil pH 6–7 provides optimal nutrients; extremes lead to nutrient imbalances.

As we age, kidney function declines, and modern diets can lead to metabolic acidosis. Blood pH below 7.35 indicates acidosis; above is alkalosis. Most enzymes function within a specific pH range; deviations can impair their activity (N Suthar, 2024).

Research Evidence on Urine pH and Bone Health

Modern diets may cause slightly acidic urine (~pH 6). Some promote alkaline diets to sell products claiming to balance the acid and base levels. Acid load can be measured by urine pH or by calculating total acid excretion, including sulfates, chlorides, phosphates, minus minerals like magnesium, calcium, potassium, and sodium. Traditional urine pH measurements may be inaccurate due to bacterial changes.

Better measurements consider post-digestion urine, reflecting the actual diet. Laboratory tests analysed urine for pH, creatinine, calcium, phosphate, and other ions. 

Results show that low urine pH or high acid levels do not increase osteoporosis risk. A single urine test cannot indicate long-term diet effects. More research is needed to assess diet effects on bone health and the validity of alkaline diets (Fenton et al., 2010).

Acid Ash Hypothesis and Bone Strength

The acid ash hypothesis claims that high-protein diets harm bones due to acid load. Excess acid is neutralised by bicarbonate from bone minerals, possibly weakening bones over time. According to this theory, acid-forming foods (dairy, grains) increase urinary calcium and bone calcium depletion.

However, reviews questioned this, considering biochemical mechanisms, protein influence, phosphate, calcium balance, and the validity of the theory. Evidence is weak on dietary acid load causing osteoarthritis.

A systematic review analysed whether high-acid diets contribute to osteoporosis, reviewing human interventional studies, long-term observations, and lab studies. Researchers examined whether reducing dietary acid load could reduce risk or slow osteoporosis progression (Fenton et al., 2011).

Meta-Analysis of pH Methods

Experts explored calcium excretion, acid load, and bone health through meta-analyses of RCTs and cohort studies. When no meta-analyses existed, individual studies were reviewed. Another meta-analysis examined effects of alkaline treatments or low acid diets on bone resorption markers (serum CTX, deoxypyridinoline crosslinks, urinary N telopeptide) using standardised mean differences with Cochrane RevMan5. 

Random effects models were applied if the heterogeneity p-value was 0.05–0.5. Sensitivity analysis excluded urine CTX due to biological fluctuations. Lab studies on bone mineral loss at different pH levels assessed acid impact on bone health within normal physiological pH (Fenton et al., 2011).

Food and pH Balance

Food does not change blood pH directly; the body manages acidity and minerals. Below is a guide to alkaline and acidic foods:

Diabetes: Science, Causes, and Lifestyle Methods to Blood Sugar Management

  October 10, 2025 Xhavid Bajrami   ,

Introduction

Cinnamon sticks, cumin seeds, star anise, cloves, leaves and nuts

Diabetes is a serious health condition that significantly affects the quality of life of families, individuals and communities across the world. 

Diabetes is ranked as one of the worldwide health conditions. In 2017, global healthcare spending on diabetes was approximately £727 billion. 

There are three main forms of diabetes: 

  • Type 1 diabetes T1D, 
  • Type 2 diabetes (T2D- diabetes mellitus),
  • Gestational diabetes mellitus GDM.
The IDF (International Diabetes Federation) has reported and monitored diabetes prevalence at regional, national, and global levels. The report shows that there is an increase in diabetes cases over time, with approximately 287 million people just in 2009. This number increased to 366 million in 2011, 382 million in 2013, 415 million in 2015, and 425 million in 2017 (Saeedi et al., 2019).

The worldwide prevalence of diabetes has dramatically increased and reached an alarming rate. According to the International Diabetes Federation, an estimated 536.6 million people were living with diabetes, but in 2021, this number was suggested to be increased by 46%, with an estimated number of 783.2 million by 2045. 

Researchers suggest that early detection of symptoms is important because it allows the treatment to begin sooner, and also helps to prevent and not delay serious macrovascular and microvascular complications(Ogurtsova et al., 2022).

Medication-Induced Diabetes

Some cardiovascular medications and metabolic medications, such as beta-blockers, statins, and thiazide diuretics, have been linked with a serious risk of developing type 2 diabetes. 

There are other drug classes associated with the risk of developing diabetes, such as: 

  • corticosteroids (steroids), 
  • antipsychotics, immunosuppressants, 
  • hormonal medications, 
and certain antivirals, which have also been associated with disturbances in glucose metabolism.
Scientific research indicates that these medications may reduce insulin sensitivity but increase glucose production in the liver, contribute to weight gain, and increase in developing diabetes, especially with the existing factors including prediabetes, obesity, cardiovascular disease or genetic predisposition. 

Despite the side effects, these medications play an important role in treating serious conditions, including heart disease, autoimmune disorders, inflammation, hypertension and mental health conditions. 

Due to this reason, healthcare professionals underline that the therapeutic benefits and the cardiovascular effects of these drugs generally outweigh the possible risk of diabetes when patients are properly monitored. Lifestyle management, regular blood glucose testing, and medical supervision can help decrease the risk of developing diabetes and ensure long-term treatment (Ogurtsova et al., 2022).

Although a few biological mechanisms indicate how cardiovascular medications may lead to hyperglycaemia, such as alterations in insulin secretion, direct toxic effects on pancreatic beta cells, and reduced insulin sensitivity and increased glucose production. 

Due to direct cytotoxic effects that support because of the damage to pancreatic beta cells. This reduces the insulin secretion, which may subsequently result in raised blood glucose levels, because hyperglycaemia activates the intracellular signalling pathway, and this stimulates the release of stored insulin in pancreatic cells. 

Thiazide diuretics may decrease insulin by causing low potassium levels (hypokalemia) and increasing the potassium gradient among beta cell membranes, and this leads to membrane hyperpolarisation. Potassium supplementation has been shown to contribute to glucose tolerance and restore insulin sensitivity, which creates effects similar to discontinuing the medication. There is another preventive method is combining thiazide diuretics with potassium-sparing agents to decrease the risk of hyperglycaemia. 

Furthermore, the mechanisms linked with thiazide-induced hyperglycaemia include raised free fatty acid levels, decreased insulin sensitivity, higher hepatic glucose production, and increased catecholamine activity. The higher dose of thiazides is linked with a higher risk of hyperglycaemia, and it is equivalent to 5 mg per day or more of Bendroflumethiazide. 

Beta blockers may also be linked to hyperglycaemia by suppressing the beginning phase of insulin release in pancreatic islet cells via alpha 1 and beta 2 adrenergic pathways. A calcium channel blocker may reduce the risk of insulin secretion and cause hyperglycaemia in case of excessive use or overdose (Widiarti et al., 2025a). 

Statins are well-known, widely used medications may reduce the risk of cardiovascular disease. Although their clinic contributions have been debated due to findings from randomised controlled trials and meta-analyses suggesting a possible association between statin use and an increased risk of developing new-onset diabetes (Agouridis, Kostapanos and Elisaf, 2015). 

Key factors of medication-induced hyperglycaemia by medication class. AP antipsychotics, GC glucocorticoids, BB beta blockers, PI protease inhibitors, PI3K phosphoinositide 3-kinase, AKT protein kinase B, CNI calcineurin inhibitors, Tori mammalian target of rapamycin inhibitors, TKI tyrosine kinase inhibitors, SSA somatostatin analogues, ADT androgen deprivation therapy, IFN-A interferon alpha(Widiarti et al., 2025b).

Insulin Resistance

The researcher focused mainly on two questions: the first was understanding how much insulin-stimulated muscle glycose production contributes to glucose metabolism in healthy individuals. The second question was how this process is affected in people with type 2 diabetes. 

Researchers used advanced 13C NMR spectroscopy to measure how glucose is converted into muscle glycogen by tracking labelled glucose molecules in muscle tissue. Once these findings were fully applied to the whole body, it was found that muscle glycogen synthesis accounted for the majority of glucose uptake and almost all non-oxidative glucose metabolism in diabetic and healthy individuals.

This emphasises how impaired muscle glycogen production plays an important role in reducing glucose control in type 2 diabetes (Shulman, 2000). In skeletal muscle, insulin signalling plays a major role in increasing glucose uptake and contributing to glycogen synthesis. 

Insulin restores glucose transport by triggering the fusion of glucose transport type 4 GLUT4 storage vesicles to the muscle cell membrane and coordinated movement. When the insulin signalling is activated, Akt suppresses AS160, also known as TBC1D4, which in turn activates Rab GTPase proteins accountable for managing vesicle trafficking and glucose transport (Lee, Park and Choi, 2022).

Type 1 Diabetes

Type 1 diabetes is worldwide recognised as a condition caused by an autoimmune process that leads to destruction of the insulin-creating beta (β) cells. According to scientists, the body's immune system mistakenly attacks these cells, resulting in a reduction or complete stoppage of insulin production. 

A long time ago, type 1 diabetes was considered a disease affecting adolescents and children, but in the last decade, this understanding has been completely changed. Now, this understanding is known as type 1, which can develop at any age. 

The most well-known symptoms at the onset of type 1 diabetes include excessive thirst (polydipsia), frequent urination(polyuria), increased hunger (polyphagia) and high blood glucose levels. Type 1 diabetes requires immediate need for insulin therapy as this is one of the defining features, and the body is no longer able to produce sufficient insulin (Atkinson, Eisenbarth and Michels, 2014). 

Despite significant advances in scientific research and treatments, researchers continue to investigate the worldwide distribution of type 1 diabetes and the possible methods for cure or prevention. Individuals who are diagnosed with Type 1 diabetes can occur at any stage of life, but it also remains one of the most common chronic diseases in childhood. 

The most frequently diagnosed conditions in children are between 5 and 7 years old, and also during puberty, and type 1 diabetes occurs more often in males. Most of the incidences of type 2 diabetes may be influenced by birth timing and seasonal factors. 

Research indicates that a higher number of cases are often diagnosed during autumn and winter, and those who are born in spring appear to have a higher risk of this condition. Additionally, these observations play a crucial role, as factors such as seasonal exposures and infections influence the disease process (Atkinson, Eisenbarth and Michels, 2014).

Type 2 Diabetes

It has been more than 50 years, and researchers know very little about the connection between type 2 diabetes and insulin resistance. Insulin resistance plays an important role in the development of the disease because it is one of the leading causes of the disease and the strongest predictor of future type 2 diabetes, and it should be treated once high blood glucose levels appear. 

Scientific research has shown that metabolic mechanisms and genetic mechanisms contribute to insulin resistance, especially through the interaction of lipoprotein lipase (LPL), mitochondrial function, and peroxisome proliferator-activated receptor delta (PPAR-δ). These procedures are believed to increase the risk of developing type 2 diabetes and to affect muscle insulin sensitivity (Taylor, 2012). 

A few years of early laboratory studies discovered abnormalities in mitochondrial function in people diagnosed with type 2 diabetes. Further to this, it was identified that mild impairments in muscle mitochondrial activities in people with type 2 diabetes, and the mitochondrial dysfunction could be involved in disease development. 

However, muscle insulin resistance is frequently assessed using the euglycemic hyperinsulinemia clamp technique, and it is considered a crucial factor in the development of type 2 diabetes. The disease is closely linked to insulin resistance in the liver rather than in muscle tissue. Researchers indicate that calorie restriction in people with type 2 diabetes reduces calorie intake, decreases liver fat and improves hepatic insulin sensitivity. The benefit of this is that it normalises fasting blood glucose levels (Taylor, 2012).

Understanding the Symptoms of Diabetes

The classic symptoms of diabetes, increased hunger (polyphagia), excessive thirst (polydipsia) are mainly observed in type 1 diabetes due to the rapid onset of severe hyperglycaemia. Those symptoms can also appear when blood glucose levels are very high in type 2 diabetes. Other symptoms are weight loss, persistent fatigue and body pain.

Nutrition and Diabetes

Nutritional management plays an important role in diabetes mellitus, and its impact on insulin resistance has been the main focus of education and research for many years. In recent research, the focus has been on the quality of dietary fats and their influence on diabetic treatment and insulin resistance. It was also mentioned that dietary fats interact with physical activities to affect insulin sensitivity, and consuming rich foods in carbohydrates (Vessby et al., 2000). 

Therefore, metabolic abnormalities in diabetes and cardiovascular disease are associated with atherosclerotic disease and linked to abdominal obesity and insulin resistance. Lifestyle intervention, including dietary improvement and physical activity, can significantly improve the health of individuals with diabetes and can influence multiple aspects of metabolic syndrome, insulin resistance, and abdominal obesity (Vessby et al., 2000).

Physical Exercise and Diabetes Management

Individuals with diabetes should consult a medical professional and undergo a medical evaluation before starting exercises or regular physical activity. Detecting any possible risk allows healthcare professionals to create an exercise plan that maximises benefits without causing harm during the exercises. Some of these guidelines are recommended by The Health Professional’s Guide to Diabetes (American Diabetes Association, 2004). 

Exercise sessions should include a proper guideline, warm-up and cool-down periods, for example, a 5 to 10-minute warm-up of light aerobic activity, including walking or cycling in a leisure centre, which prepares the lungs, heart, muscle for increased intensity. Once the exercises are complete, gently stretch for 5 to 10 minutes and then do a cool down for 5 to 10 minutes. 

Physical exercises are recommended three to four times a week for 30 to 60 minutes, and have resulted in reducing HbA1c by 10–20%, especially in individuals with type 2 diabetes. Evidence from multiple clinics demonstrates that exercise improves insulin sensitivity, reduces plasma insulin levels and weight loss may help reduce the risk or delay the onset of type 2 diabetes (American Diabetes Association, 2004).

Historical and Lifestyle Perspective on Diabetes Prevention

In the real world, diabetes is both practical and achievable. The major cause of developing diabetes is excessive consumption of calories for long periods, reduced physical activity, and high intake of proteins and fats. Maintaining a balanced diet and increasing physical activity can play an important role in reducing the risk of developing diabetes (Shi, 2016). 

In one of the Chinese medical texts, the Yellow Emperor’s Canon, which is more than 2000 years old, states that diabetes as condition associated with consuming sweet food and the development of obesity (Lee, Park and Choi, 2022).

Conclusion

Diabetes is a worldwide health challenge and a complex condition that affects millions of people in the world. According to scientific research, show that diabetes is linked to insulin resistance, genetic, metabolic dysfunction and medical use. 

Understanding the difference between type 2, type 1, and gestational diabetes helps improve treatment, early detection, and long-term management. Maintaining a regular diet balance, physical activity, proper nutrition, and monitoring properly play an important role in monitoring blood glucose levels and reducing organ damage and complications, including cardiovascular disease. 

Early detection, continued lifestyle treatment, and appropriate treatment can maintain a good quality of life and successfully manage diabetes. Increasing public awareness, education, and using strategies to prevent it remain essential for the worldwide burden of diabetes and increasing overall population health.

Juices and Nutrition that Support Wellness and Immunity

  September 09, 2025 Xhavid Bajrami   

Introduction

Fresh juice ingredients including oranges lemon ginger and green leaves prepared for immune boosting drink

Maintaining proper nutrition and hydration is essential for supporting overall health and reducing the risk of disease. 

Modern research continues to emphasise the importance of nutrient- and vitamin-rich diets in strengthening the immune system and promoting long-term well-being.

Among the various nutritional approaches, it is worth noting that juice therapy is based on fresh vegetable juices, but also selected herbal teas have gained increasing attention, some of which have an important role in daily life. When combined with a balanced diet and careful hydration, these practices can help provide minerals, vitamins and essential bioactive compounds that particularly support digestion, nutrient absorption and immune function.

 This article explores the scientific background behind key juices, the role of important nutrients like vitamin C, minerals, and how herbal teas can complement a better wellness-focused lifestyle.

Offering these methods that combine a balanced diet and mindful hydration can strengthen immunity, provide a variety of rich minerals, vitamins and support detoxification, digestion and absorption. Regarding evidence-based insights into nutrition

Beetroot Juice

Beetroot juice is well-known in health and nutrition research because it is very rich in inorganic nitrates, NO3, as well as bioactive elements such as polyphenols and betalains. Although these nutrients are converted into nitrites and then into nitric oxide through the well-recorded nitrate-nitrite-NO pathway, a procedure that can take place even under low oxygen or acidic conditions and is frequently seen in physical activities. 

Nitric oxide plays a crucial role in regulating blood vessel function, regulating oxidant balance, and influencing muscle contraction, supporting mitochondrial function efficiently, making as promising nutritional option for increasing different roles of physical health. As mentioned, beetroot juice can decrease blood pressure and also improve endothelial function. 

Researchers have extended studies, such as illustrating potential benefits for mitochondrial activity, cerebral blood flow, muscle function, and cognitive performance. In addition, the benefits of beetroot juice are not only due to nitrate content, but also factors like oral microbiota health, age, diet and metabolic staus the effect how efficiently nitrate is converted into nitric oxide(Lee et al., 2026).

Pomegranate Juice

Pomegranate (Punica granatum) is a long-cultivated fruit that belongs to the Punicaceae family and is frequently called “the miracle fruit” due to eating its seeds as food, juice and its functional products. Modern clinical research and pharmacology have highlighted the broad-ranging medicinal properties of pomegranate and its juice. 

Pomegranate is strongly considered to be rich in dietary polyphenols with strong antioxidant properties. It has various health benefits, including managing diabetes, obesity and inflammation. The factors of polyphenols in pomegranate juice include anthocyanins, tannins, and flavonoids, and it is explored among chemical composition, biological effects and metabolism. It has significant advantages for the production of high-quality juice (Basu and Penugonda, 2009).

Wheatgrass Juice

Modern research identifies herbs as valuable sources of bioactive compounds. Wheatgrass, as young shoots of Triticum aestivum that belong to the family Gramineae, is an annual grass native to Southwest Asia and the Mediterranean, and now wheatgrass is cultivated worldwide. Wheatgrass is rich in essential minerals such as magnesium, iron, phosphorus, manganese, zinc and copper. 

Wheatgrass has tocopherols, providing a high amount of vitamin It has 70% chlorophyl, a molecule that is almost similar to haemoglobin. It contributes to metabolism, reduces acidity, restores blood alkalinity and also supports healthy cellular function by acting as a detoxifying agent. 

It can be consumed as a powdered extract or fresh, providing chlorophyll, 17 amino acids such as 8 essential, minerals, vitamins and proteins. Although it was used traditionally to manage health conditions. It has benefits for high blood pressure, pancreas health, anaemia, skin issues, constipation and asthma. 

Nutritional studies regularly show wheatgrass to be rich in magnesium, chromium, zinc, selenium, and antioxidants such as vitamin E and C, in anti-anaemic factors, such as vitamin B12, folic acid, iron, and pyridoxine, including proteins and amino acids. Scientists have discovered that it demonstrates its antioxidant capacity against cancer both in vivo and in vitro (A pilot study on wheat grass juice for its phytochemical, nutritional and therapeutic potential on chronic diseases, 2026).

Vitamin C and Immune System Support

Vitamin C plays an important role in the synthesis of hormones, including catecholamines (example, norepinephrine) and amidated peptides (e.g., vasopressin), which are crucial for cardiovascular responses during serious infections. 

Recent research among its classic functions has revealed that vitamin C regulate cell signalling and gene transcription by modulating epigenetic marks and transcription factor activity. Moreover, proteins such as asparagine and prolyl hydroxylases that contribute to downregulate transcription component hypoxia-inducible factor-1α (HIF-1α), need vitamin C as a cofactor. 

Vitamin C also contributes to DNA and histone methylation by assisting enzymes that hydroxylate these epigenetic marks. It also contributes to leukocyte function and barrier integrity in the immune system. The skin, which provides a main barrier against pathogens, consists of high concentrations of vitamin C, especially in the epidermis. 

Vitamin C is actively transported into skin cells through SVCT1 and SVCT2 transporters, highlighting its importance in skin health. Furthermore, vitamin C may stimulate collagen gene expression, and it also supports tissue repair and integrity (Carr and Maggini, 2017).

Recommendation for Using Herbal Teas

There are many herbal teas from different regions that can support different functions of the body. The herbal teas provide bioactive plant compounds with detoxification benefits, as well as antioxidant and anti-inflammatory properties. The most recommended options are:

  • Cranesbill Tea: Many people use it to promote cleansing, and it supports kidney function.
  • Sage Tea: Widely known for soothing the throat, decreasing oxidative stress, and providing anti-inflammatory and antioxidant benefits.
  • Marigold (Calendula) Tea: Valued for skin-supportive effects and immune-enhancing properties.

Highly recommended is that juice therapy is followed as a short-term regimen. During this crucial period for transformation of wellbeing and body, it is best to avoid solid food. This allows the digestive system to rest while delivering essential nutrients.

Juice Ingredients and Preparation

A day-to-day therapeutic blend includes:

  • 150g carrots
  • 250g beetroot
  • 100g celery
  • 50g apple
  • 1 small piece of ginger

This mixture creates a nutrient-dense juice rich in minerals and antioxidants.

Preparation Instructions for the Juice

Blend all ingredients in a food processor until smooth. Drink slowly, using a spoon, to increase enzymatic breakdown. Complement intake with herbal teas for hydration throughout the day.

Sage Tea Preparation

  1. Steep sage herbs in hot water for about 10 minutes.
  2. Boil the herbs in 500ml water for 3 minutes, then let it cool.
  3. Add one teaspoon of peppermint and balm (Melissa officinalis) and steep for an additional 9–10 minutes.

This combination enhances both flavor and therapeutic effects.

Supports antioxidant balance, increases immune activity, and reduces inflammation

  • Deficiency increases susceptibility to respiratory infections such as pneumonia.
  • Studies indicate that low vitamin C levels contribute to increased COVID-19 risk.
  • Adjusts multiple immune cells and promotes production of antimicrobial proteins.
  • Constant supplementation is more effective than high single doses.

Conclusion

To summarise this article, including nutrient-rich herbal juices and teas in a balanced diet can provide valuable support for overall health and immune function. 

Ingredients such as beets, pomegranates, and wheatgrass provide a wide range of bioactive compounds, including antioxidants, essential vitamins, and minerals that contribute to cellular defence, cardiovascular health, and metabolic balance. Additionally, key nutrients like vitamin C play an important role in immune defence, supporting cellular function, tissue repair, and the body’s natural defences. 

When these nutrients are combined with herbal teas that offer anti-inflammatory and antioxidant properties, these nutritional approaches can complement a lifestyle focused on wellness. However, it is important to recognise that these nutritional approaches should complement, but not replace, a varied and balanced diet in daily life. 

Instead, it can be used as a supportive approach along with whole foods, proper hydration, and healthy lifestyle habits. Individuals considering significant dietary changes, including fasting or intensive fluid regimens, are encouraged to contact or seek guidance from a qualified healthcare professional. Overall, a consistent and balanced nutritional approach remains the foundation of long-term health, with juices and herbal teas serving as helpful additions rather than stand-alone solutions.
