About Bones and Alcohol


 

Some studies have suggested that moderate alcohol consumption can have a beneficial effect on bone mineral density, but others have not. We know that excess alcohol consumption can damage bone, and that people who drink alcohol at high levels are at greater risk of bone thinning and fractures.

New research suggests that older women who consume a calcium-rich diet and occasionally drink small amounts of alcohol may be less likely to have bone thinning than their peers.

In a small study published in the Journal of the American College of Nutrition in December, 2002 researchers looked at the effects of alcohol, caffeine and smoking on the bone mineral density of 136 post-menopausal white women between the ages of 57 to 89. The women were asked about calcium, alcohol and caffeine consumption as well as their history of smoking and exercise habits.

Women who consumed a moderate amount of wine, beer or liquor had a higher bone mineral density than those who did not drink. The average drink size was one beer or one glass of wine a day.

It appears that a small amount of alcohol promotes osteoblasts, which are bone forming cells. On the other hand, alcohol also inhibits osteoclasts, which are bone resorption cells.
