Hard Cheese
Hard cheeses like parmesan or Romano pack about 300 to 335 mg of calcium in one ounce. Skip the powdered types and go for the real deal, which tastes better and doesn’t contain additives. Other cheese varieties are good sources, too, with cheddar at 205 mg per ounce and part-skim mozzarella at 210 mg per ounce.
Try it: Use super-thin slices of hard cheese to top a pizza or salad (extra credit for including calcium-rich kale and other bitter greens).
Turnip Greens
These nutritious greens are often overlooked, but a chopped and cooked 1-cup serving contains almost 200 mg of calcium, says Zeratsky. If you’re tired of other greens like spinach, these are a nice change of pace with a slightly bitter flavor.
Try it: Sauté turnip greens with olive oil and garlic and toss over pasta, or substitute for other greens in your favorite recipes.
