Prevents Cancer 

Sweet potatoes include several antioxidants that may help protect against some malignancies.

Similarly, a study showed rats fed purple sweet potato diets had decreased incidences of early-stage colon cancer. 

The anthocyanins in the potatoes may protect you from cancer. Moreover, Vitro studies also discovered extracts of orange sweet potatoes and sweet potato peels to have anti-cancer potential.

Healthy for Your Digestive System

Sweet potato provides 4g of fibre and both insoluble and soluble fibre. Soluble fibre creates food for the healthy bacteria in your gut, generally known as your gut microbiome. In contrast, insoluble fibre improves bowel regularity, preventing constipation. According to a study, just two weeks of eating a higher fibre diet was enough to notice positive results.

Improves Brain Health

Sweet potatoes include a variety of antioxidants, including carotenoids and anthocyanins. This help reduces age-related reductions in brain function and the risk of neurodegenerative diseases like Alzheimer’s and dementia. For instance, carotenoids in orange sweet potatoes decrease cognitive decline. At the same time, anthocyanins found in purple sweet potatoes increase memory, as noted in animal experiments.

Sweet Potato Provides Energy

Sweet potatoes have more energy than non-starchy vegetable alternatives, making them an excellent fuel source for everyday activities and sports performance.

Healthy for Skin and Hair

Collagen is a protein in the skin, hair, muscles, tendons, ligaments, and bones that keeps them healthy. It requires vitamin C for its synthesis. While the body’s collagen synthesis gradually slows as we age, eating adequate vitamin C is crucial to maintain its generation. Sweet potatoes include vitamin C and A, aiding skin and hair by preventing them from drying out.
