Can Drinking a Cola a Day Increase Your Risk of Osteoporosis?

 Yes,  researchers at Northeastern University in Boston saw 3.7 to 5.4 percent less bone density in the hips of females who drank at least one cola drink a day.

The researchers believe this is due to two factors.  One factor is the amount of caffeine in the cola ( heavy coffee drinkers also have decreased bone density ).  The second factor is the phosphorous level in the colas.  When a person ingests regular amount of phosphorous, calcium in the person's bloodstream may bind to the phosphorous, which makes the calcium unavailable for bone remodeling -  resulting in decreased bone density.
