“…The most important member, with the greatest biological potency and accouting for 90% of the vitamin activity in the tissues, is atocopherol. It is this form which is often taken as the representative of the whole group (34)(35).…”

“…The decreased cellular immunity seen with aging or during the development of AIDS is markedly improved by the intake of a high vitamin E diet. In addition, vitamin E playa role in differentiation of immature T cells in thymus via increased positive selection by thymic epithelial cells, which results in the improvement of decreased cellular immunity in the aged (35,39).…”

The immune system guards against invasion by foreign microrganisms and molecules. In this way, it protects from fatal illnesses and communicable diseases. Its proper functioning is fundamental for survival. Research has demonstrated that proper nutrition plays a crucial role in the prevention of chronic disease. Protein-energy malnutrition is associated with a significant impairment of cell-mediated immunity, phagocyte function, the complement system, secretory immunoglobulin A antibody concentrations, and cytokine production. Deficiency of single nutrients also results in altered immune responses; this is observed even when the deficiency state is relatively mild. Of the micronutrients, zinc, selenium, iron, copper, vitamins A,C,E and B, and folic acid have important influences on the immune response. It is now apparent that vitamin E and β-carotene have more subtle roles and that deficient dietary intake of these vitamins increases susceptibility to certain cancers and cardiovascular disease. This reflects, in part, the antioxidant properties of the vitamins and their ability to reduce free radical-mediated damage to DNA, proteins and lipid membranes. These findings have considerable practical and public health significance. The aim of this review is to give an up-to date account of the roles of selected fat-soluble vitamins in health and disease.

“…Intake of carbohydrates during prolonged exercise at submaximal intensity attenuates the increase of plasma cortisol and cytokine levels after exercise, which could lead to the inhibition of immunosuppression [105][106][107]. Vitamin C and vitamin E have actions that promote immunity, and are essential for T cell differentiation and for maintenance of T cell function [104,108,109]. However, there is limited evidence about the effects of vitamins supplementation on immune function in relation to exercise.…”

Appropriate nutrition is an essential prerequisite for effective improvement of athletic performance, conditioning, recovery from fatigue after exercise, and avoidance of injury. Nutritional supplements containing carbohydrates, proteins, vitamins, and minerals have been widely used in various sporting fields to provide a boost to the recommended daily allowance. In addition, several natural food components have been found to show physiological effects, and some of them are considered to be useful for promoting exercise performance or for prevention of injury. However, these foods should only be used when there is clear scientific evidence and with understanding of the physiological changes caused by exercise. This article describes various "functional foods" that have been reported to be effective for improving exercise performance or health promotion, along with the relevant physiological changes that occur during exercise.

Functional foods and the immune system: a review

In the last decade, preventive medicine has undergone a great advance, especially in developed countries. Research has demonstrated that nutrition plays a crucial role in the prevention of chronic diseases, as most of them can be related to diet. Functional food enters the concept of considering food not only necessary for living but also as a source of mental and physical well-being, contributing to the prevention and reduction of risk factors for several diseases or enhancing certain physiological functions. In reference to the immune system, many studies have pointed out that not only pre-and probiotics, but also single micronutrients incorporated into functional foods contribute to an enhancement of immunocompetence. In fact, one of the authorized claims consists of pointing out the immunomodulator properties of functional foods. In this article, the effect of some functional foods and ingredients such as probiotics, selenium and dietary antioxidants (vitamins A, E and C) on the immune function are reviewed. However, the optimum intake level and recommended amounts of functional foods have not yet been established. Thus, in order to remove the controversy surrounding functional food, further research studies are necessary, both in experimental animals and in humans. Finally: efforts should be directed towards the ultimate goal, that is, a 'functional diet'.
