Eat These 9 Foods to Boost Your Immune System

Fortified Orange Juice

orange juice good for immune system

Although I am not a fan of drinking fruit instead of eating it, the immune boost offered by fortified orange juice is hard to surpass.

One cup contains 100% of the Daily Value for vitamin C, a critical antioxidant required for proper immune system function, plus 25% of the Daily Value for vitamin D.

This is critical since most individuals have vitamin D deficiency, which makes them more prone to disease.

Supplements also may help prevent respiratory infections, according to 2017 research.
