Milk is a healthful choice for most kids, unless it's raw. According to the U.S. Food and Drug Administration, unpasteurized milk can pass harmful bacteria to your kids, including E. coli or Listeria. The same goes for raw juices, such as unpasteurized apple cider. Soy milk contains phytic acid, which health research nonprofit the Weston A. Price Foundation cautions may cause growth problems in children. So, now you're back to thinking plain old cow's milk is the right choice. Just don't reach for a gallon of pre-mixed chocolate milk. One 16-ounce (450-gram) bottle can dish out 10 grams of fat and 60 grams of sugar.
