The fall is a great time for root vegetables. Often these types of veggies need time and warmth to develop, meaning they're best harvested in early or late fall depending on when they're planted.
And one of the tastiest -- and healthiest -- root vegetables is the sweet potato.
Sweet potatoes are native to Central and South America and are commercially produced in the southern United States, particularly in Louisiana and North Carolina [source: University of Illinois Extension].
Sweet potatoes are extremely rich in vitamin A, which is important for good vision, healthy skin and a strong immune system, among other things. A serving of sweet potatoes typically has twice the daily recommended amount of vitamin A [source: Louisiana Sweet Potato Commission].
With an ANDI score of 83, they're also practically fat- and sodium-free, so feel good when you bake those sweet potatoes.
