Building a strong immune system through nutrition involves a combination of key vitamins and minerals. Consuming a variety of fruits and vegetables, particularly those high in vitamins C and E, supports immune function by providing antioxidants that combat free radicals. Foods rich in zinc, such as nuts and seeds, are critical for immune system regulation. Additionally, incorporating probiotics from yogurt or fermented foods can enhance gut health, a key player in immune responses. A balanced diet ensures that the body receives the necessary nutrients to protect against illness effectively.
