Worst: Mashed Potatoes

This holiday favorite can go either way. In their natural state, potatoes offer plenty of nutrients (Vitamin C and potassium, for starters) in relatively few calories. But beware of potatoes prepared with too much butter, whole milk, heavy cream, or other fatty ingredients. The very ingredients that make them creamy can wreck a perfectly nutritious choice by adding hundreds of calories and many grams of saturated fat. Our lightened version boosts flavor with a small amount of a buttery, creamy cheese.
