coffee 3A cohort study appearing in Osteoporosis International (Volume 17, Number 7 / July, 2006) looked at the relationship between coffee consumption and osteoporosis in 31,527 Swedish women. Coffee, tea and caffeine intake were determined by food frequency questionnaires. The subjects were monitored for a little more than 10 years. During that time there were 3,279 reported instances of osteoporotic fracture. Increased coffee intake was associated with a greater risk of fracture–especially if calcium intake was low.
