Potatoes are very nutritious and good for you. It is how they are prepared, topped, and eaten that determines whether the consumer will reap the benefits. You know, Irish immigrants were the among the healthiest, longest-living people to come to North America and what do you think they ate a lot of? ;) Of course, it is a starchy food so people who cannot eat starch are out of luck (same with rice). It is the starch we need to be wary of.
