Muffins can be a nutritional boon or a bust, depending on what's in them. Those gigantic bakeshop muffins can contain over 500 calories and 20 grams fat. Smarter choice: Home-baked muffins bursting with antioxidant-rich dried fruits and fiber from whole wheat flour and wheat germ. Wheat germ is also high in the mineral zinc, which contributes to healthy skin and a strong immune system. Add a boost of antioxidants by adding the freshest berries of the season.
