Which are healthiest – red, white or purple potatoes?

If you’re having potatoes for dinner tonight – pick the purple kind...

Those little roasting potatoes come in several colors, red, white, yellow, brown and purple. Nutritionally speaking, the red, white and yellow potatoes are pretty similar – but the purple potatoes are a bit superior. Like blueberries, the compounds that give the purple spuds their rich color contain antioxidants and help protect the brain against age-related disease. Purple potatoes are also high in iron, potassium and vitamin C.
