Benefits of Sweet Potatoes

Vitamin A

Sweet potatoes are a healthy source of beta-carotene. Beta-carotene is an antioxidant responsible for the bright orange color of sweet potatoes, carrots, pumpkin, and it is found to help us have a healthy vision. One cup (~200 g) of cooked sweet potato has over seven times the daily amount of beta-carotene the average adult needs.
Vitamin A is also an important vitamin that helps us boost our immune system.

Sweet potatoes are also a fiber-rich food. Fiber is found to not only keep your bowel movements regular, but also help fight inflammation, reduce your risk of cancer, and promote gut health. A medium-sized sweet potato has about ~4 g of fiber.
