This document discusses various foods that may help boost the immune system. It outlines foods such as blueberries, dark chocolate, turmeric, broccoli, sweet potatoes, spinach, ginger, garlic, almonds, oranges, and kiwifruit that contain beneficial antioxidants and vitamins like vitamin C, vitamin A, flavonoids, and carotenoids. These nutrients are thought to support the immune system by protecting cells from damage, reducing inflammation, and improving the body's immune response and ability to fight infection and disease. While many of these foods show promise in boosting immunity, more research is still needed on some to confirm their preventative effects.
