Elderly women who drink large amounts of coffee may experience greater bone loss than those who do not, according to a new study published in the American Journal Of Clinical Nutrition , 2001 (pp. 694-700). The finding arose from research conducted as part of a larger long-term study of osteoporosis, during which scientists examine the interaction between caffeine intake, genetic type and the disease by compared the bone mineral density (BMD) of women in high and low categories of caffeine consumption.
