One-half cup of purple potatoes contains 70 calories, 15 grams of carbohydrates, 1 gram of fiber, 2 grams of protein and no fat.
These potatoes can be beneficial to your health due to their abundance of antioxidants.
Anthocyanin is the pigment that creates the purple color in these potatoes and also acts as an antioxidant.
All potatoes are naturally high in potassium, which helps regulate blood pressure. But the extra antioxidants in purple potatoes make them even more effective than other potato varieties. A study conducted by the USDA among overweight participants suffering from hypertension reported that consuming six to eight golf ball-sized purple potatoes twice daily for one month reduced blood pressure by an average of 4 percent. These antioxidants also strengthen your immune system and can help prevent certain heart diseases and cancers.
Purple potatoes have a delicate skin which contains many of the beneficial nutrients. This skin should be kept on when cooking to gain the maximum nutritional benefit.
So add some color and nutrition to you next meal!
