| Nutritionist Fiona Hunter agrees that potatoes have a bad rep.

| At one time I ate a diet of about 90% potatoes for six weeks or so. I love spuds and this was a comfort-food diet. Convenient too, since one can buy them pre-mashed and microwaveable. Lost 30lbs during that period and felt very good indeed. | At one time I ate a diet of about 90% potatoes for six weeks or so. I love spuds and this was a comfort-food diet.
