This root vegetable is an important source of vitamin A, which helps boost the number of infection-fighting white blood cells in the body, especially important if you’re dealing with any sort of road rash or open cut. Sweet potatoes also have loads of vitamin C, which promotes healthy skin growth and aids in collagen production for healing the connective ­tissues so often strained by athletes.
Dosage: At least one serving every day; for variety, alternate with carrots and spinach.
