The efficient operation of the immune system constitutes a fundamental protective mechanism that determines the body’s capacity to defend against pathogenic microbial invasions and minimize the risk of bacterial or viral infectious diseases. Amid rising infection rates—particularly during periods of heightened morbidity—the conscious shaping of dietary habits and the implementation of nutritional strategies aimed at optimizing immunological responses assume critical importance. Comprehending these mechanisms not only facilitates more effective prevention but also supports the body’s recovery processes during convalescence.
Decreased immunity in adults and children
Frequent infections and infections in children may be due to external and internal factors. One of the endogenous causes of the decline in immunity in children is the immaturity of the immune system, which has not developed enough to deal with the harmful pathogens. In order for the child's immune system to develop properly, the best conditions should be provided, taking into account external factors and developmental needs. One factor affecting the development of immunity is nutrition.
Weakened immune system symptoms
Decreased immunity may be characterized by non-specific symptoms such as constant fatigue, feeling tired, sleep problems, weakness. There is a tendency to recurrent infections, frequent pneumonia, bronchitis, ear, or sinus infections. So if we have recently seen frequent recurrences of infections that are accompanied by cough, fever, fatigue or even fever it is one of the signs of a weakening of the immune system.
Right nutrition in the face of the coronavirus
For the proper functioning of the immune system, adequate doses of vitamin A in the diet are necessary to reduce the number of T-lymphocytes and the cellular activity of phagocytes. Vitamin A deficiencies cause disorders in the immune systems, which increase the risk of infectious diseases and, consequently, mortality. Deficiency in vitamin A, which is essential for the production of T lymphocytes, reduces the number and the metabolic activity of soya pigments. However, vitamin A deficiency must also be avoided in the context of protein acids, which are the source of essential oils of corn, as well as the sources of essential vegetable products: soya fats, omega-6 fatty oils, omega-3 fatty acids and omega-3 oils. It is essential in the preparation of edible oils and fats. It also plays an important role in the preservation of essential fats and minerals, in particular, in protecting against the effects of omega-6 and omega-6 fats on the body.
How do you boost your immunity?
In order to improve immunity, you should look closely at your diet and take care to balance it with all nutrients, vitamins and minerals. You should also remember to limit your diet with alcohol and eliminate your consumption. It is also important to use herbal sprays with an immune-supporting effect.
