HOW CAN SODA DAMAGE YOUR BONES?
The phosphoric acid in soda has a negative effect on bone mass in women who drink thiis sweet treat regularly. Women who drink three or more sodas per day were shown to have 2.3 to 5.1 lower hip bone mineral densities than women who drank less than one soda per day, according to a study by Katherine Tucker, researcher at Tufts University. The study found no link between bone loss and soda consumption in men.
Another way soda can damage your bones is by replacing other drinks that contain calcium or are fortified with calcium, such as milk and juices. If you drink soda instead of milk or other calcium-rich drinks, your total daily intake of calcium will be reduced. Much of your bone mass is built before age 18. Teens who do not get enough calcium when they are young will not be able to catch up later in life and build bone mass. This can lead to weak bones, fractures and osteoporosis.
Some sodas contain caffeine and caffeine is associated with lower bone mineral density. Drinking colas that contain caffeine increases your daily total of caffeine, putting you at risk for lower bone density. Caffeine causes your kidneys to excrete calcium, interfering with your body’s ability to absorb calcium and protect your bones.
EXCESS PHOSPHORIC ACID
Drinking soda every day increases the amount of phosphoric acid in your body, unbalancing the natural environment of your gut and possibly blocking calcium absorption, notes Tucker. High levels of phosphorus and low calcium levels in your body may lead to bone loss, but it is unclear if soda can increase your phosphorus levels enough to cause bone resorption. More research is needed before a conclusion can be drawn.
