Be sure that the next time you buy milk, you choose organic in paper cartons. Recently, Dr. Oz rated dairy a "Must Buy Organic" food. Organic milk comes from cows that aren't fed genetically modified food or injected with antibiotics. To make your milk work even harder for you, be sure to get paper cartons -- light destroys vitamin A and riboflavin. Pricey national brands and generic brands of organic milk must meet the same standards set by the U.S. Department of Agriculture, so no matter which way you go, you'll be sure you're getting the same benefits.
