What Is Immunity? Immunity is the capability of an organism to sustain the “self” molecules that constitute its own body and to resist and destroy the “nonself” molecules which have their origin from toxins and infectious microorganisms. With increase in age, our immune response capability weakens and hence we become susceptible to respiratory infections like influenza, Covid-19, pneumonia and cancer. Nutrition and immunity are related to each other in the elderly people. Micronutrient malnutrition is a condition in which a person is deficient of some important essential vitamins and minerals as he or she eats less and often has less variety in the diet. They do not acquire the essential amounts of zinc, iron, folic acid, selenium, copper, vitamins A, B6, C, and E. If there is no time to prepare healthy daily diet, dietary supplements will surely help the older people to maintain a healthy immune system.
