Of course, milk and other dairy products are good sources of calcium, but you'll find a good selection of calcium-fortified foods in the grocery aisles, too. A cup of calcium-enriched orange juice contains 300 milligrams of calcium, just like you’ll find in a cup of milk (and the acid in the juice promotes absorption). Breads, cereals and grains are also calcium-enriched these days. Calcium occurs naturally in tofu, broccoli, figs, greens (including collard greens, kale and spinach, bok choy) and baked beans.

So let's hear it for lattes (a Starbucks latte has 400 milligrams of calcium from the milk), cheese pizza (about 100 mg a slice), almonds and filberts (about 250–300 mgs/cup) and milkshakes (about 400 mg).
