Foods: Green tea leaves.
Immune Benefit: Green tea is loaded with polyphenols, particularly catechins, which have antioxidant and anti-inflammatory properties. Regular consumption may help support the immune system.
11. Poultry:
Nutrients: Protein, Vitamin B6
Foods: Chicken, turkey.
Immune Benefit: Poultry is a good source of lean protein, essential for the production of antibodies and immune cell function. It also provides vitamin B6, which is involved in immune system regulation.
12. Papaya:
Nutrients: Vitamin C, Papain
Foods: Fresh papaya.
Immune Benefit: In addition to being rich in vitamin C, papaya contains papain, an enzyme with anti-inflammatory properties. Both vitamin C and papain contribute to a healthy immune response.
