Bones
A study published in the “Archives of Pediatric and Adolescent Medicine” in 2000 found that athletic teen girls who consume colas have five times the risk of bone fractures as those who don’t consume cola drinks. X-ray tests on 1,672 women in the Framingham Osteoporosis Study between 1996 and 2001 found phosphoric acid-containing colas -- but not clear carbonated soft drinks that use citric acid instead -- were linked to low bone mineral density in women. However, a clinical study at the Creighton University Osteoporosis Research Center, published in 2001 in the “American Journal of Clinical Nutrition,” found no impact of carbonated soft drinks with phosphoric acid on calcium excretion in bone and suggested the skeleton effects of carbonated drinks are caused by drinking sodas instead of calcium-containing milk.
