Acids that stress the body’s pH can also come through diet. There are obvious dietary sources of acid such as carbonated sodas that contain carbonic acid. Some sodas, such as Coca-Cola, also contain phosphoric acid. The extreme acid loads of carbonated sodas stretch your body’s acid-neutralizing capacity to its limits. The constant draw on calcium from bones, for instance, is associated with fivefold increased fractures in high school girls who consume the most carbonated colas.
