Sweet Potato Health Benefits:
Purple-hued sweet potatoes contain Anthocyanidins that are flavonoids with antioxidant properties. Flavonoids are responsible for suppressing stomach, colon, breast and lung cancerous cell growth. In addition, Anthocyanidins prevent sticking of platelet cells, that help reduce blood clots, and help prevent heart disease. Sweet Potatoes (purple) also contain polyphenols like cyanidin and peonidin, that have shown remarkable results against colorectal cancer.
Sweet potatoes contain huge amounts of Vitamin B6, which is very important for the breakdown of the substance, homocysteine. Homocysteine causes the hardening of the blood vessels which leads to several heart diseases. Vitamin B6 keeps the blood vessels flexible and allows easier blood flow. Moreover, potassium in the sweet potatoes helps the body get rid of excess sodium and regulates the fluid balance in the body.
In spite of being a mid-glycemic food, sweet potatoes are known to regulate the blood sugar levels. The vegetable contains large amounts of dietary fiber, which controls digestion and releases a hormone, adiponectin. This hormone is responsible for insulin metabolism, thus indirectly controlling diabetes II.
