Like cheese, you'll probably have an easy time getting your kids to eat yogurt. And that's a good thing, because every serving of yogurt contains calcium, protein, carbohydrates, vitamin B, zinc and phosphorus. If you want to really kick it up a notch, buy yogurt with live active cultures to help boost the immune system and promote intestinal health. All-natural yogurt with fresh fruit will add even more nutritional value. For a healthy sweet treat, add some fresh granola and chocolate chips to low-fat vanilla yogurt. You can even freeze yogurt with fresh fruit for an alternative to ice cream.
