Coffee vs. Tea: Impact on Bone Health in Older Women
What Happened?
A new study from Flinders University in Australia investigated the relationship between coffee and tea consumption and bone health in women aged 65 and older. The research, published in the journal Nutrients, followed nearly 10,000 women for a decade, tracking changes in bone mineral density (BMD).
Why It Matters: Osteoporosis and Bone Health
Osteoporosis is a significant global health concern, affecting approximately one in three women over 50. it leads to millions of fractures annually, impacting quality of life and healthcare systems. Given the widespread consumption of coffee and tea, understanding their effects on BMD is vital for preventative health strategies.
Key Findings: Tea vs. Coffee
The study revealed differing effects of coffee and tea on BMD. While previous research yielded mixed results, this long-term study provides more nuanced insights.The specific findings are detailed below.
| Beverage | Effect on Bone Mineral Density (BMD) |
|---|---|
| Coffee | Associated with a slight decrease in BMD. |
| Tea | No significant association with changes in BMD. |
What does This Mean?
The findings suggest that regular coffee consumption may be linked to a modest reduction in BMD in older women. This doesn’t necessarily mean coffee *causes* bone loss, but it highlights a potential association. Tea, conversely, did not show a significant impact on BMD in this study.
