Mechanisms for a Beneficial Effect of Moderate Alcohol Consumption on Osteoporosis in Women, Menopause Reveals

Women after menopause tend to develop weaker bones from what is known as osteoporosis, which may lead to fractures (especially hip fractures) from falling. The weakness of the bones results from an imbalance between the normal resorption (a type of dissolving of old bone) and the laying down of new bone, an ongoing process for both men and women referred to as "bone turnover." For poorly understood reasons, after menopause the resorption of old bone in women continues but new bone is laid down less well, leading to a decrease in bone density. A variety of substances (calcium, vitamin D and various medications) have been used in an attempt to prevent the development of osteoporosis; in epidemiologic studies, moderate drinking of alcohol has also been shown to lower this risk.
