Eating a variety of nutrient-rich foods is key to supporting immune function and overall health. A balanced diet with a wide range of foods gives the body the nutrients it needs. Foods high in vitamins and minerals like vitamin C, vitamin D, and zinc are important for immune health.

Nourishing your body with the right foods boosts your immune system’s fight against infections. Vitamins and minerals like vitamin A, B vitamins, vitamin E, and selenium are also vital. For example, vitamin C helps make white blood cells, which fight infections.
