Carbonated water and bone health
By Jennifer Nelson, M.S., R.D. and Katherine Zeratsky, R.D.
Is there any nutritional downside to drinking carbonated water? This is a question we are often asked. Carbonated water is purported to prevent calcium absorption, thus increasing the risk of osteoporosis.
In reality there's no good evidence that carbonated water causes harm to your bones. The confusion may arise because of research that found a connection between carbonated cola drinks and low bone mineral density. But this association wasn't seen with noncola carbonated drinks. So if you like the bubbles, you can keep sipping your carbonated water.
If you're open to trying other types of water, there's some promising research that mineral waters with calcium may actually benefit your bones.
Keep your bones healthy with calcium-rich foods such as low-fat dairy, fortified foods and vegetables. Regular weight-bearing exercise is important as well.
Both carbonated water and mineral water are usually calorie free, but check the label to be sure. If you're looking to add a little flavor, just add a squeeze of lime or lemon.blog index
