Purple yams are rich in antioxidants, including anthocyanins and vitamin C. Antioxidants help protect your cells from damage caused by harmful molecules called free radicals. Free radical damage is linked to many chronic conditions, such as cancer, heart disease, diabetes, and neurodegenerative disorders.

The flavonoids in purple yams have been shown to help lower blood sugar in those with type 2 diabetes. Obesity and inflammation caused by oxidative stress increase your risk of insulin resistance, poor blood sugar control, and type 2 diabetes.

Purple yams are an incredibly nutritious starchy root vegetable. Their powerful antioxidants may help reduce your blood pressure and blood sugar levels. They are tasty and versatile with vibrant color, making them an exciting ingredient that can be used in a variety of sweet and savory dishes.
