What's happened
Recent studies from Flinders University show that daily tea consumption is linked to higher bone mineral density in women aged 65 and older, potentially reducing osteoporosis risk. Moderate coffee intake appears safe, but high consumption may negatively impact bone health, especially for women who drink alcohol.
What's behind the headline?
The new research underscores the importance of beverage choices in managing bone health among older women. Tea, rich in catechins, promotes stronger bone formation and reduces fracture risk, especially in women with obesity. Conversely, high coffee consumption, particularly over five cups daily, interferes with calcium absorption due to caffeine, increasing osteoporosis risk. The findings suggest that moderate tea drinking could be a simple, accessible strategy to support bone strength. However, the complex relationship between coffee, alcohol, and bone health indicates that lifestyle factors must be considered holistically. This research will likely influence dietary recommendations for aging populations, emphasizing moderation and the potential benefits of tea. It also highlights the need for further studies to explore long-term impacts and mechanisms, especially in diverse demographic groups.
What the papers say
The articles from NY Post and The Independent present consistent findings, emphasizing that tea consumption correlates with higher bone mineral density in older women, while excessive coffee intake may be detrimental. The NY Post highlights that antioxidants in tea, such as catechins, support bone formation, whereas caffeine in coffee can hinder calcium absorption. The Independent notes that the benefits of tea are modest but meaningful, especially for women with obesity or high alcohol consumption. Both sources caution against drastic lifestyle changes but suggest that enjoying a daily cup of tea could be a simple step toward better bone health. The studies also connect high coffee intake with increased pain levels in older adults, adding a layer of complexity to coffee's health effects. Overall, the consensus points to moderation and awareness of beverage choices as key factors in maintaining bone health with age.
How we got here
Osteoporosis is a widespread condition affecting millions of women, especially after menopause, due to hormonal changes that weaken bones. Dietary habits, including beverage choices, have long been studied for their impact on bone health. Recent research from Australia and other institutions has focused on the effects of tea and coffee, given their popularity and nutritional components.

Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain Coffea species. When coffee berries turn from green to bright red in color – indicating ripeness – they are picked, processed, and dried.
