What do you do? A piece of fresh fruit just won't satisfy a craving for something richer and gooier - like a dish of velvety ice cream, or a slab of thick milk chocolate. But your conscience just won't let you feast on fatty foods and empty calories.

Here are some nutritious appeasers. They're all good providers of calcium, especially important for the child who just won't drink milk. Those with molasses are also great supplies of iron, the mineral in short supply for many women. Best of all, they're low in fat, lower in "empty calories," and fun to eat.

These nutritious sweets are easy to prepare, and are great to keep on hand when an apple or orange just won't do.
