Too much coffee may weaken bones, study finds

Following nearly 10,000 older women for 10 years, researchers found that tea drinking was associated with slightly higher hip bone density. Moderate coffee consumption did not appear harmful, but drinking more than five cups a day was linked to lower bone density. The findings suggest tea may offer a small bone-health boost, while excessive coffee could carry some drawbacks.
