Don't overdo it on the meat

Too much animal protein can interfere with the way your body absorbs calcium. When federal researchers set the daily requirement for this mineral, they assumed that you'd be eating the recommended two servings of animal protein (6 ounces total, or two pieces about the size of a deck of cards) each day. For every additional serving you eat, it's a good idea to drink an extra glass of milk in order to make sure you're still getting enough calcium.
