A potato has lots of nutrients and so it is a good food. The thing that changes it from a good food is the size of the potato and the choice of toppings. We have found that chili (meat and beans), jalapenos, green onions and other light toppings are not too bad. Also, moderation is key. An alternative would be "rosemary potatoes," which you can find on the web. A good website is one by the USDA.
