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.
A new study from Flinders University suggests that tea may support bone health in older women, while heavy coffee consumption could weaken bones. Researchers analyzed data from nearly 10,000 women aged 65 and older, tracking their coffee and tea intake over 10 years. The study, published in Nutrients, found that women who drank tea had slightly higher total hip bone mineral density (BMD) compared to non-tea drinkers.
Moderate coffee consumption (about two to three cups per day) did not negatively impact bone health, but women who drank more than five cups daily showed lower BMD. The relationship between coffee and bone health appeared to depend on other health factors, such as alcohol consumption and obesity. The researchers suggest moderate tea consumption could help support bone health in older women, while very high coffee intake may not be ideal, especially for women who drink alcohol.
