One of the best ways to stay healthy is by choosing an array of foods to boost your immune system. Eating healthy, antioxidant-rich foods such as fruits and vegetables, whole grains, and lean protein is an important part of maintaining good immune system health to help ward off infection and illness.
Foods that have it provide nutrients like vitamins B6 and B12, both of which keep your immune system working like it should. Vitamin B6 comes in protein-rich foods like turkey and beans, as well as potatoes, spinach, and enriched cereal grains. Meats, milk, and fish also contain vitamin B12, a powerful immune booster. Minerals like selenium and zinc also keep your immune system going strong. These minerals are found in protein-rich foods like beans, nuts, meat, and poultry.
