First of all, the diet should provide enough protein. For the body of an adult woman, this figure will be about 90 - 120 grams of protein per day. Dietary nutrition, which provides the necessary amount of protein in the diet, has a huge impact on the strengthening of human immunity. Suffice it to say that many protective substances that provide resistance to pathogenic bacteria are, by their chemical nature, proteins. And for the synthesis of such substances in our body, we must receive with food the necessary "building materials", which are the proteins of food.
The next moment, which should pay attention to the organization of dietary nutrition to strengthen immunity, is a sufficient amount in the diet of vitamins. These nutritional components must be delivered to our body in very small quantities (most often only a few millimograms or micrograms per day). However, the role of vitamins in strengthening immunity is difficult to overestimate. The fact is that many enzymes that carry out the most important immunological reactions in the body, in order to perform their protective functions, require the inclusion of various vitamins in their composition. Naturally, in the absence of vitamins in the diet, these enzymes can not trigger many protective reactions, which ultimately leads to a decrease in human immunity.
Ensure the intake of vitamins in the body with dietary nutrition can be due to the inclusion in the diet of a variety of fruits and vegetables (preferably fresh), since the largest amount of these nutritional components is contained in products of plant origin. Of products of animal origin, the greatest number of vitamins contain liver, kidneys, chicken eggs, fish oil. Synthetic multivitamin complexes will also help you to fill the lack of vitamins in dietary nutrition, but use these drugs should be strictly in accordance with the attached recipes. Remember that the overabundance of vitamins in the diet is harmful to health, not less than their lack.
Mineral substances - this is another of the most important components of dietary nutrition, if desired, to strengthen immunity. Such mineral elements as iron, magnesium, calcium, phosphorus, selenium, etc. are also able to significantly increase human immunity. For example, iron is part of hemoglobin - a substance that carries oxygen to all cells of the body. The lack of iron in the diet causes the development of anemia and oxygen starvation, which, in turn, negatively affects the state of immunity. Therefore, with the rational organization of dietary nutrition should pay great attention to the provision in the diet of the required amount of minerals.
And, of course, you need to remember such folk remedies against colds like onions and garlic - these foods contain a large number of phytoncides (volatile substances that exert a depressing effect on pathogenic bacteria). Daily including dishes with onions or garlic in the dietary diet, thereby we provide increased resistance of our body to catarrhal diseases due to the persistent strengthening of immunity.
