Annually, since 2002, on the initiative of the World Health Organization, the World Day of Immunity is celebrated on March 1, the goal is to attract public attention to the problems associated with the spread of various immune diseases, as well as the preservation and strengthening of immunity in general.

The ancient Romans and Greeks believed that a person with good immunity is "free" from illness. After all, even during the terrible epidemics of plague and smallpox, not all fell ill. The immune system, like everything in man, is complex and multifaceted. The strength of immunity, like our overall health, is about 50% dependent on the lifestyle we choose. Among the main destroyers of immunity specialists call frequent stresses, improper diet, constant lack of sleep, long exposure to the sun, too much physical activity and, conversely, a sedentary lifestyle. And, of course, bad habits - smoking, alcohol, drugs.

Immunity depends on the work of the intestine: 80% of the "cells" of the immune system is located in it. And that means everything that we eat or weakens, or strengthens our invisible defenders. Vegetables and fruits - vegetable food - should constitute 50% of the diet.

Sour-milk products containing bifido- and lactobacilli fight with harmful microorganisms for a place in our intestines and create the main protective barrier against pathogens.

Only 10% of people can boast of powerful immunity, which protects them from almost all diseases. Another 10% have congenital immunodeficiency: they get sick very often. The remaining 80%, the strength of the immune system depends on the conditions and lifestyle.
