In Western medicine, many studies have shown that sweet potatoes contain a unique protein that has antioxidant effects. The protein in sweet potatoes has about 1/3 the antioxidant activity of glutathione (one of the body's important products that plays a role in creating antioxidants). This helps explain the healing properties of sweet potatoes.

Not only do sweet potatoes have antioxidant properties, they are also packed with nutrients that are good for your health.

Sweet potatoes are rich in vitamin A (in the form of beta-carotene), vitamin C, vitamin B6, and some minerals such as manganese, copper, potassium, and iron. In particular, sweet potatoes are also known as a food rich in soluble fiber, which is good for the digestive system.

Thanks to its rich content of vitamin A and vitamin C, sweet potatoes are an anti-inflammatory food that can help prevent and treat diseases. Beta-carotene and vitamin C are antioxidants that help the body eliminate free radicals.

In addition, sweet potatoes also contain vitamin B6, which is necessary for the body to convert homocysteine, a product in the process of creating an important amino acid in protecting cells.

Sweet potatoes are cheap but good for your health.
