Our team gets lots of questions about bone health, ranging from questions like “does soda decrease my bone strength?” To “how much calcium and Vitamin D are needed to maintain bone health?” In honor of National Nutrition Month, last week, we shared with you details on the roles of Calcium and Vitamin D in your bone health, and foods you can consume to make sure you get enough of each. This week, we want to share some interesting findings from new research being conducted around soda, and its effect on your bone strength.
There are many activities and behaviors that can serve to either improve or worsen bone health, but many recent studies have been conducted to determine if there is a link between soda consumption and decreased bone health. Check out some interesting take- aways from just a few of those studies below:
- According to findings from a study at Harvard, 9th and 10th grade girls who consume sodas are at three times the risk for bone fractures compared to those who don’t.
- Research out of Tufts University shows that “women–but not men–who drank more than three 12-ounce servings of cola per day had 2.3 percent to 5.1 percent lower bone-mineral density in the hip than women who consumed less than one serving of cola per day.”1
- In a 2010 study from the Journal of American Dietetic Association, 170 girls were followed from age 5 to 15. Of those, the participants who drank soda at age 5 were less likely to drink milk throughout childhood than those who didn’t consume soda at age 5. Those who drank soda from the age of 5 were also more likely to consume diets lacking in calcium, fiber, vitamin D, protein, magnesium, phosphorus and potassium.
- In a 2001 study out of Creighton University Osteoporosis Research Center , researchers followed 32 people for a month and had them drink various formulations of soda with differing levels of caffeine, phosphorus or citric acid so the research team could take urine samples and determine how much calcium the subjects were excreting. Those who drank caffeine-rich sodas excreted calcium; the others did not.
While all of the research conducted so far indicates that there is more to be done to directly tie cola consumption to decreased bone health, it is clearly a hot topic for future medical investigation. We will follow up on our blog as more details emerge.
