The immune system is our shield against illness, and nutrition plays a key role in supporting it. If you want to increase your natural defenses, it’s worth including foods in your diet that support the production of white blood cells, contain antioxidants and calm inflammatory processes in the body. Meet the 15 most effective foods that help build a strong immunity – naturally and without chemicals.
