May Enhance Brain Function
Consuming purple sweet potatoes may improve brain function.

Animal studies have found that the anthocyanins in purple sweet potatoes can protect the brain by reducing inflammation and preventing free radical damage (29Trusted Source, 30Trusted Source, 31Trusted Source).

Supplementing with anthocyanin-rich sweet potato extract has been shown to improve learning and memory in mice, possibly due to its antioxidant properties (32Trusted Source, 33Trusted Source).

No studies have been done to test these effects in humans, but in general, diets rich in fruits, vegetables, and antioxidants are associated with a 13% lower risk of mental decline and dementia (34Trusted Source, 35Trusted Source).

SUMMARY
Animal studies have shown that sweet potatoes may improve brain health by reducing inflammation and preventing mental decline. However, it remains unknown whether they have the same effects in humans.

Orange-fleshed sweet potatoes are one of the richest natural sources of beta-carotene, a plant-based compound that is converted to vitamin A in your body (36Trusted Source).

Vitamin A is critical to a healthy immune system, and low blood levels have been linked to reduced immunity (37Trusted Source, 38Trusted Source).

It’s also key for maintaining healthy mucous membranes, especially in the lining of your gut.

The gut is where your body is exposed to many potential disease-causing pathogens. Therefore, a healthy gut is an important part of a healthy immune system.

Studies have shown that vitamin A deficiency increases gut inflammation and reduces the ability of your immune system to respond properly to potential threats (39Trusted Source).

No studies have been conducted to determine whether sweet potatoes, in particular, have an effect on immunity, but eating them regularly can help prevent vitamin A deficiency (40Trusted Source).
