Are you craving something creamy and cold? Summer is a time when many people enjoy frozen sweet desserts. When you head out to the local ice-cream shop with the kids, consider a low-fat or fat-free frozen yogurt. At about 100 calories per half-cup serving, they are lower in calories and saturated fat than most ice creams. If you are interested in a higher protein dairy snack, consider refrigerated yogurt. It is nutrient rich and can be fat-free and sugar-free.
