Chocolate Milk and Calcium Absorption

Most children love to drink chocolate milk. Many mothers, however, have heard that chocolate milk decreases calcium absorption in the intestines. It was found that chocolates contain oxalic acid, which can bind to the calcium in milk, thus preventing the absorption of calcium in the body. The amount of oxalic acid contained in chocolate milk, however, is far smaller than the chocolate milk’s calcium content.

Calcium in Chocolate Milk

Everyone, especially growing children and elderlies, needs calcium for strong bones, and milk is an ideal calcium-rich drink. Chocolate milk is especially popular among children because of its added chocolate flavor. It contains around 300 mg of calcium per cup. The amount of oxalic acid is so little that it can bind to just 6 mg out of the 300 mg of calcium in milk.

Foods Containing Calcium and Oxalic Acid

Drinking chocolate milk, or plain milk, can provide the body with a great deal of calcium. Calcium can also be found in other foods, such as cheese and yogurt. There are also foods that contain oxalic acid in small amounts, such as chocolate bars, spinach, tea, chard, broccoli and okra. Eating them often can decrease bone density if not enough calcium is taken in by the body. Some studies have shown that people who eat chocolates everyday have bone density lower than those who just occasionaly eat chocolates.
