Yogurt is crawling with bacteria -- and the more of it you eat, the better. Be sure to buy yogurt with a seal that guarantees it has live, active cultures. These cultures -- especially acidophilus and bifida -- colonize the lower intestines with beneficial bacteria while muscling out disease-causing bacteria. Eating yogurt may help prevent diarrhea in people taking antibiotics. Yogurt is easy to digest, especially for those who are lactose-intolerant, and is an excellent source of calcium, protein, riboflavin (a B vitamin), vitamin B-12 (which may be low in vegetarian diets) and vitamin A. To avoid unwanted saturated fat, choose nonfat or low-fat yogurt.
