Food sources of calcium (calcium-rich foods)

About 96.5% of foods contained calcium. On the basis of the proposed method, the average (%) of foods containing appropriate calcium levels (to achieve adequate calcium intake) in food groups was 11.38%, of which 8.39% was the average of calcium source (good source of calcium) foods, and 2.99% was the average of high-calcium (excellent source of calcium) foods. Animal products, excluding dairy products and bone-containing foods, had almost no foods containing appropriate calcium levels. Plant products, excluding calcium-fortified foods and dairy-containing foods, had few foods containing appropriate calcium levels. In addition, some foods containing appropriate calcium levels in plant products contain oxalic acid (oxalate) or phytic acid (phytate), which decreases calcium absorption. Major foods containing appropriate calcium levels were allocated to dairy products, dairy-containing foods (except dairy products), and calcium-fortified foods.

The highest amounts of calcium were found in breakfast cereal (calcium-fortified), calcium-set tofu, malted milk drink (calcium-fortified), nutrition shake (calcium-fortified), almond milk drink (calcium-fortified), coconut milk drink (calcium-fortified), formulated bar (calcium-fortified), granola bar (calcium-fortified), waffle (calcium-fortified), cheese product (calcium-fortified), soy milk (calcium-fortified), milk beverage (calcium-fortified), whey protein powder isolate, orange juice (calcium-fortified), rennet tablets (unsweetened), sheep milk, cow milk, grapefruit juice (calcium-fortified), buttermilk, chocolate bar (calcium-fortified), Indian buffalo milk, yogurt, goat milk, canned Atlantic sardine with bone, kefir, drink mix (calcium-fortified), American cheese (calcium-fortified), Gruyère cheese, vegetable juice (calcium-fortified), pasta in tomato and cheese sauce (calcium-fortified), orange drink (calcium-fortified), soy yogurt (calcium-fortified), Swiss cheese, fat-free mozzarella cheese, rice milk drink (calcium-fortified), collards, hard goat cheese, fat-free cheddar cheese, and acid whey.
