Seems to me potato skins are a appetizer at many upscale restaurants, plus all the nutrients are absorbed from the dirt they are grown in and are contained in the skin. Remove the skin and all you have left is the starchy part of the potato, no nutrients left at all.
Mike's right, they ain't french fries if there ain't any skin on them. Besides if eatin dirt was bad for ya I would have been dead long ago, see race picture on dirt track in my signature I've eaten a lotta dirt over the years. That's why dirt's for racin on, and asphalt's for gettin to the races, I know eatin asphalt ain't good for ya.........................................
