Many Americans drink soda everyday without giving it a second thought even though it’s considered common knowledge that sugary drinks aren’t good for your health. Each year, Americans consume an average of 57 gallons of soda per person (1). So how bad is soda? Well, let’s just say doctors aren’t divided on the subject.
Soda and Osteoporosis
Cola soda contains both phosphoric acid and caffeine. In 2006, the Framingham Osteoporosis Study examined the bone mineral density (BMD) of 1413 women and 1125 men (2).
It found that daily cola intake was associated with significantly lower BMD in the hips of women, which are much more prone to bone loss than men (3).
Some studies suggest that this phenomena is caused by too much phosphorous, which can inhibit calcium absorption (4). It’s also thought that phosphoric acid in cola leaches calcium out of bones (5).

Another study suggests that drinking 330 mg of caffeine, or about four cups of coffee can cause bone loss (4). Caffeine is thought to interfere with calcium absorption and lead to calcium loss through urine.
If you suffer from osteoporosis, are over the age of 50 or have a condition which impairs nutrient absorption (such as Crohn’s disease), you should avoid soda at all cost.
