8 Foods That Boost Immunity

Boost Immunity

Your immune system protects you from infection-causing organisms. It comprises of a network of biological structures that destroy the invading germs. However, to carry out its functions, your immune system needs certain nutrients that assist in production of the cells and tissues that defend the body from the harmful bacteria, viruses and fungi. A diet rich in immunity-boosting foods is essential for strengthening the immune system and minimizing risk of infections. These foods are considered to be the best dietary sources of nutrients that support the normal function of the immune system. A diet deficient in foods that are known for their immune boosting effect weakens the immune system and makes you susceptible to infection. To stave off infection, add the following foods to your diet.
