Calcium content of some foods
Content of calcium (mg)
Milk and milk products
Ø Milk, yogurt and butter milk / 1 cup, 200g tub of yogurt or 200ml of calcium- fortified (added calcium) soy milk= 300mg
Leafy green vegetables
Ø broccoli, collards (cabbage family), bok choy, Chinese cabbage and spinach / 1 cup of cooked spinach =100 mg,
however only 5% of this may be absorbed, this is due to the high levels of oxalate which is a compound in spinach that can reduce the absorption of calcium
1 cup of cooked broccoli = 45 mg of calcium,
the absorption from broccoli is much higher at around 50–60 per cent
Fish
Ø sardines and salmon (with bones) / ½ cup of canned salmon = 402 mg of calcium
Nuts and seeds
Ø brazil nuts, almonds and sesame seed paste (tahini) / 15 almonds= 40 mg of calcium
Calcium fortified foods
Ø breakfast cereals, fruit juices and bread / 1cup of calcium-fortified breakfast cereal (40 g) = 200 mg of calcium
½ cup of calcium-fortified orange juice (100 ml) = 80 mg of calcium
2 slices of bread (30 g) = 200 mg of calcium
