Consumption of cola, or carbonated beverages, has been associated with low bone mineral density in teenage girls, and now a new study finds similar results in women.
The American Journal of Clinical Nutrition published results of a large analysis of more than 2,500 men and women. It looked at cola consumption, including regular, diet, caffeinated and non-caffeinated drinks. They then measured bone mineral density in several areas of the hip and spine to determine any differences.
Carbonated beverages such as cola contain high amounts of phosphoric acid, which inhibits calcium absorption and may contribute to calcium loss from the bones.
Low bone mineral density contributes to fracture risk and the condition osteoporosis. Women are more at risk for osteoporosis than men, though both sexes can develop the condition.
They found that women who consumed a cola a day had lower bone mineral density than women who consumed only one cola a month. These women were more at risk for osteoporosis and fractures regardless of other risk factors and health variables.
There was no association between cola consumption and low bone mineral density in men.
They also looked at total calcium intake, and found it to be lower in women who consumed more cola, though not because of decreased dairy intake.
Women who have a family history of osteoporosis or any other factor that increases their risk should reconsider their choice if consuming cola regularly. A simple change such as beverage choice may have a serious impact on health status later in life. Drink water, its good for you and does not contribute to any health conditions and protects against many.
