Individual yogurts are a cinch to take on the road, and they'll provide lots of calcium -- especially important for growing kids and women. Yogurt has also been credited with reducing the risk of colon cancer, lowering cholesterol and helping decrease yeast infections. Avoid ones with fruit already added; they often contain high amounts of sugar. Instead, buy plain or vanilla yogurt and stir in your own fresh berries, chopped fruit, raisins or sliced almonds. Let kids come up with their own flavor combinations for a fun treat.
