Overview
- A decade-long analysis of nearly 10,000 women aged 65 and older found daily tea drinkers had slightly higher total hip bone mineral density than non–tea drinkers.
- Moderate coffee intake showed no harmful association with bone density, whereas consuming more than five cups per day correlated with lower BMD.
- Women with higher lifetime alcohol consumption appeared more vulnerable to coffee’s negative association, and tea’s benefit was more evident among women with obesity.
- The findings come from repeated measures in the Study of Osteoporotic Fractures and were published in the journal Nutrients by Flinders University researchers.
- Scientists emphasized small effect sizes and the study’s observational design, advising that routine tea or coffee habits need not change without other concerns.
