The problem is that people rarely eat them unadorned. Toppings like regular sour cream, bacon and cheese can send calorie and fat levels soaring. If you want to prepare low-fat mashed potatoes, use warmed chicken broth or buttermilk instead of whole milk and butter, and save 40 calories and 4 to 5 grams of fat for each cup. 20 percent more vitamin C and 5 percent more B6, compared to the peeled version. Also remember portion size when watching your waistline.
Spuds come in a variety of sizes.
A medium potato or cup of mashed potatoes is considered a serving. Store raw potatoes in a cool, dark place. But keep raw potatoes out of the refrigerator because the starch will convert to sugar. Always pierce potatoes before baking to allow moisture to escape for a fluffy texture. And if you wrap potatoes in foil prior to baking, always unwrap leftovers and immediately refrigerate.
