Diet


GENERAL RULES FOR A BALANCED DIET ARE:

– Prefer Higher-fibre Carbohydrates, such as Wholegrain cereals and bread, whenever possible
– There should be More Vegetables Than Fruit in your diet, for a daily total of seven portions
Milk and other Dairy foods provide Calcium, which is needed for healthy teeth and bones, and also protein, vitamins and minerals
– Eat meat, fish, eggs and plant sources of protein In Moderation
– There is evidence that red meat and processed meat increase the risk of diseases
Avoid too much sugar, fat and salt


EXERCISE AND HYDRATION

Moderate exercise has been shown to enhance immune function whereas prolonged or intense exercise has shown immunosuppressive results.

A reason for that is that dehydration leads to an increase in the cortisol hormone levels in the blood during prolonged or intense exercise. Although there is limited evidence showing the direct effects of dehydration on immune function, dehydration has been assumed as one of the possible causes of immune dysfunction in marathon runners.

Dehydration has been found to decrease salivary occurrence. Immunoglobulin A (s-IgA), contained in saliva, is one of the first lines of defence of the immune function on foreign bacteria.

To that corresponds an increase of URTI (upper respiratory tract infection)’s incidence. Consequently maintaining appropriate hydration during exercise is fundamental.

In addition, evidence is now emerging that exercise has anti-inflammatory effects in the long term, which is one of the major health benefits of regular exercise. Individuals who practice physical training have a reduction in the levels of biomarkers that are used to assess systemic inflammation.


EXERCISE AND FOOD

Energy consumed during exercise is mainly supplied by carbohydrates and lipids, so it is important for improvement of endurance to regulate the metabolism of these two substrates.

It has been suggested that supplements containing fructose, which cause less stimulation of insulin secretion and are unlikely to inhibit lipolysis, rather than common carbohydrates such as glucose and sucrose, may be better for improving endurance.

In order to maximize the effect of resistance exercise, it is important to maintain the muscular pool and blood levels of various amino acids that are substrates for the synthesis of muscle proteins. For this purpose, it is necessary to maintain a positive nitrogen balance by increasing the dietary protein intake.  Also the timing of intake is important for building muscles efficiently. Eating a meal immediately after resistance exercise may contribute to a greater increase of muscle mass compared with ingesting a meal several hours later.

Consumption of carbohydrates with protein can accelerate the synthesis of muscle protein via the actions of insulin, which increases protein synthesis and impedes its catabolism.  Amino acids are utilized for the synthesis of muscle protein, and some of these molecules also wield a variety of physiological effects.

Intake of carbohydrates during prolonged exercise prevents a decrease in immunocompetence, by reducing plasma cortisol and cytokine levels after exercise. A high-carbohydrate diet that includes citric acid —contained in lemons, oranges, and limes— prevents muscle/joint injuries or fatigue, promoting a recovery of glycogen storage in muscle.


FOOD-DEPENDENT EXERCISE-INDUCED ANAPHYLAXIS

Exercise-induced anaphylaxis is a mast cell (“master regulators” of the immune system) dependent reaction, which is induced by physical activity.

Conventional EIA is caused by temperature elevation induced by exercise.

Food-dependent Exercise-induced Anaphylaxis is associated to the intake of specific foods or drugs.

Foods involved in the onset of Food-dependent Exercise-induced Anaphylaxis include mostly wheat and shellfish, but also eggs, dairy, fruits and tomatoes. Aspirin’s intake increases the occurrence of allergy symptoms. Alcohol consumption can provoke a variety of hypersensitive reactions.

The clinical symptoms concern not only the skin (Urticaria) and mucosa (Angioedema) but also other organ systems like the lungs (Dyspnea), cardiovascular system (Hypotension) and gastrointestinal tract can be affected.

It appears that allergic anaphylaxis can be initiated by the onset of exercise, in patients who have low-grade allergies to specific foods. Thus exercise helps increase the absorption of food allergens in the GI tract and the degranulation of mast cells.


 

GLUTEN-RELATED DISORDERS

Gluten is the main storage protein of popular grains like wheat, rye, barley. Gluten is a complex mixture of proteins, mainly gliadin and glutenin. Gliadin is highly resistant to digestion in the gastrointestinal tract, escaping degradation in the human gut.

 

 

 

 

 

 

Groups of gluten-related disorders are manifested not only by disturbances in the gastrointestinal tract, but also by dermatological, haematological, endocrinological, rheumatological, gynaecological, dental and neurological symptoms.

Gluten ataxia is a disorder of the central nervous system, that results in a lack of coordination of complex movements like walking, speaking, and swallowing.

Peripheral neuropathy is consequence of inflammation in peripheral nerve fibres, which variously impairs sensation (sensory nerves), movement (motor nerves), or gland or organ function (autonomic nerves).

Minor neurological damages appear as subtle impairments to memory, attention, decision-making, and the speed of cognitive processing collectively referred to as “brain fog”.

After the administration of a Gluten Free Diet the symptoms recede. However, when the diet is abandoned, all the symptoms recur.

Like other autoimmune diseases, celiac disease occurs in more women than men. In fact, women are diagnosed with celiac disease two to three times more often than men. Current research indicates that 60% to 70% of those diagnosed with celiac disease are women.
