CARBONATED DRINKS DO NOT CAUSE OSTEOPOROSIS

People who drink several carbonated drinks each day are at increased risk for osteoporosis. A recent report from the University of Nebraska shows that the only way that carbonated drinks cause osteoporosis appears to be when it prevents people from getting other sources of calcium such as from dairy products.

This study shows that drinks with caffeine do increase calcium loss through the kidneys, but those without caffeine do not. However, the people on the caffeinated drinks who put out increased amounts of calcium in their urines in the morning, put out less calcium in their urines in the afternoon. The authors feel that neither carbonated nor caffeinated drinks cause osteoporosis directly, but people who drink several carbonated drinks daily may not drink milk and therefore may not get enough calcium in their diet, so they suffer a calcium deficiency and weakened bones.
