Overview
- Flinders University analyzed repeated diet and bone measurements in nearly 10,000 women aged 65 and older over about 10 years, with results published in Nutrients.
- Daily tea consumption was linked to modestly higher total hip bone mineral density compared with no tea.
- Moderate coffee intake showed no clear harm, but drinking more than five cups per day correlated with lower hip bone density.
- Women with higher lifetime alcohol use appeared more susceptible to coffee’s negative associations, and tea’s apparent benefit was more evident among women with obesity.
- Researchers and experts stressed the observational nature and small effect sizes and advised maintaining proven bone-health measures such as adequate calcium and vitamin D.
