A new Australian study finds that drinking multiple cups of black tea is linked to lower fracture risk in older women. The study, which looked at 1,188 older women (aged 75 and over) participating in the Calcium Intake Fracture Outcome Study in Australia, found that those who drank at least three cups of tea a day had a 30% lower risk of having any osteoporosis–related fracture compared with women who rarely drank tea. A key ingredient in tea that is thought to benefit bone health are flavonoids.
A key ingredient in tea that is thought to benefit bone health are flavonoids (a type of antioxidant). Flavonoids are found in diverse plant foods ranging from fruits and vegetables, herbs and spices, essential oils, and beverages. For each one-cup/day increase in tea intake, there was a 9% decrease in the risk of a serious osteoporotic fracture, but this was no longer significant after adjustment for bone-mineral density. Although previous studies have consistently shown associations between flavonoid consumption and higher bone mineral density, this is the first study to show a positive link between flavonoid intake and fracture risk. The study was also unique in that it looked exclusively at women aged 75 and above, a high-risk age group.
