Sweet potatoes are also rich in vitamin A, beta carotene, potassium and fiber, just like carrots, so they're also good for your eye health. Their sweet flavor makes them a favorite at mealtime, so it's easy to get all that good nutrition into your diet without the usual bitter flavor that green vegetables tend to have.
Serve baked sweet potatoes with olive oil, or a touch of a sweet glaze. Their sweet flavor also blends well with onions and nuts. You can also take a break from regular French fries and make sweet potato fries instead, with a little bit of molasses drizzled on the top.
