7 Fall Superfoods That May Help Boost Your Immunity During Cold and Flu Season

The natural orange color found in the flesh of sweet potatoes is due to the rich content of beta carotene, a natural antioxidant that is converted to vitamin A in the body. Since low levels of vitamin A are linked to a compromised immune system, keeping intake adequate is key during the fall. Tip: bake a few sweet potatoes at once, and use the flesh in recipes like pancakes and smoothies for a supplement-free and naturally sweet boost of nutrition.
