Sweet potatoes are an excellent source of vitamin A and vitamin C and a good source of fiber, vitamin B6, and potassium. Vitamin A is a fat-soluble vitamin that helps maintain good vision, protects the body from infections, supports cell growth, and keeps skin healthy. Sweet potatoes are one of the richest plant sources of beta carotene, which the body converts into vitamin A. Antioxidants, like carotenoids, help keep the immune system healthy.
California ranks third in sweet potato production behind North Carolina and Louisiana. Almost 80 percent of California production takes place in Merced County. There are many varieties of sweet potatoes, but the three main varieties found in California markets are Hanna or Golden Sweets, orange-fleshed Beauregards, and Red “Yams.”
