Study Suggests Coffee Might Affect Bone Health for Older Women
If you enjoy sipping coffee throughout the day, you might want to reconsider your choices, especially if you’re a woman in your senior years. A new study conducted by researchers at Flinders University highlights a possible link between high coffee consumption and lower bone mineral density (BMD) in older women after menopause.
The study, published in the journal Nutrients, looked at the coffee and tea habits of nearly 10,000 women aged 65 and older over a decade. During this time, researchers also assessed their bone density at critical points like the hip and femoral neck—areas commonly affected by osteoporosis-related fractures.
The findings were significant: women who drank tea tended to have better bone density compared to those who consumed over five cups of coffee daily. In contrast, moderate coffee consumption—about two to three cups per day—did not seem to harm bone health.
Moreover, the researchers observed that various lifestyle factors played a role. For instance, higher alcohol consumption appeared to lower femoral neck BMD in coffee drinkers, while tea’s positive impact on bone density was notably stronger in women living with obesity.
Osteoporosis poses a worldwide health challenge, affecting individuals regardless of age, gender, or ethnicity. The study reported that about one-third of women and one-fifth of men over the age of 50 deal with fractures related to osteoporosis. This condition is especially concerning for women, who generally have lower bone mass and experience rapid bone loss after menopause.
In the United States, a significant rise in adults aged 50 and over with low BMD in the hip or spine is expected in the coming years, potentially adding to the healthcare costs and long-term effects linked to osteoporosis.
The research team explained that they explored the connection between coffee, tea, and bone health because diet can significantly influence the prevention of chronic illnesses. Both coffee and tea are among the most widely consumed beverages around the world.
Ryan Liu, a co-author of the study, mentioned that tea contains compounds called catechins, which may help build bone and reduce the breakdown of bones. On the other hand, while coffee does contain caffeine that might interfere with calcium absorption and bone metabolism, this effect is minimal and could be balanced by including milk in your coffee.
Liu clarified that there’s no need to completely eliminate coffee or flood your diet with tea. However, drinking tea in moderation could be one simple way to bolster bone health, especially for women who drink alcohol and may be at higher risk.
Lisa Young, a registered dietitian and adjunct professor at New York University, cautioned that while these findings are insightful, they should be interpreted carefully. The study only shows associations and does not definitively prove that coffee weakens bones or that tea strengthens them. Limitations also exist, including varied lifestyles among participants, and the study primarily focused on bone density rather than actual fractures.
The symptoms of osteoporosis can include back pain, gradual height loss, and a hunched posture. Young reassured that moderate coffee consumption seems to be safe, and there is no urgent need to switch beverages solely for bone health.
For optimal bone health, the best approaches are still to ensure adequate intake of calcium and vitamin D, stay active, and avoid excessive alcohol and smoking. As Young suggested, balance is key—while moderate coffee can be part of a healthy lifestyle, overdoing anything is not advisable.
