"Among ladies, cola drinks had been associated with lower bone mineral density," mentioned lead researcher Katherine Tucker, director of the Epidemiology and Dietary Evaluation Program at the Jean Mayer USDA Human Nutrition Research Heart on Aging at Tufts University.
There was a fairly clear dose-response, Tucker added. "Ladies who drink cola each day had lower bone mineral density than those who drink it only once per week," she said. "In case you are frightened about osteoporosis, it's most likely a good suggestion to modify to a different beverage or to limit your cola to occasional use."
The report was printed within the October situation of the American Journal of Scientific Nutrition.
About 55 percent of Americans, largely girls, are at risk for creating osteoporosis, according to the National Osteoporosis Foundation.
Within the research, Tucker's group collected data on greater than 2,500 participants in the Framingham Osteoporosis Research, averaging just under 60 years of age. The researchers looked at bone mineral density at three totally different hip websites, as well as the spine.
They found that in girls, ingesting cola was related to lower bone mineral density in any respect three hip websites, no matter age, menopause, complete calcium and vitamin D intake, or smoking or drinking alcohol. Women reported drinking a median of five carbonated drinks per week, 4 of which were cola.
Bone density amongst women who drank cola day by day was nearly 4 % much less, compared with ladies who did not drink cola, Tucker said. "That is quite important when you find yourself talking about the density of the skeleton," she said.
Cola intake was not associated with lower bone mineral density in men. The findings had been similar for weight loss program cola, but weaker for decaffeinated cola, the researchers reported.
The rationale for cola's effect on bone density may need to do with caffeine, Tucker said. "Caffeine is thought to be related to the danger of decrease bone mineral density," she said. "But we found the same factor with decaffeinated colas."
Another rationalization may need to do with phosphoric acid in cola, which can cause leeching of calcium from bones to help neutralize the acid, Tucker said.
One expert agrees that women ought to scale back the amount of cola they drink.
"I would count on this finding," stated Dr. Mone Zaidi, director of the Mount Sinai Bone Program at Mount Sinai College of Medication, in New York City. "It is most likely a caffeine-related problem."
Women should restrict their caffeine intake, Zaidi said. "Caffeine interferes with calcium absorption, which results in much less bone formation," he said.
This is usually a problem for young women who never develop peak bone density, Zaidi noted. "Youthful ladies who have a whole lot of coke won't kind bone to an extent their friends would; so, years later, in menopause, they'll be deprived," he said.
