A new long-term study suggests that what older women drink every day — tea or coffee — could have a measurable impact on bone health and osteoporosis risk. Researchers found that moderate tea consumption was linked to slightly stronger bones, while very high coffee intake may be associated with lower bone mineral density in some women.
The findings come from a 10-year study involving nearly 10,000 women aged 65 and older and were published in the journal Nutrients. Researchers tracked participants’ tea and coffee habits alongside repeated bone density measurements over time.
Tea Drinkers Showed Slightly Better Bone Density
According to the study, women who regularly drank tea had marginally higher total hip bone mineral density compared to non-tea drinkers. Bone mineral density is an important marker used to assess osteoporosis risk and fracture vulnerability.
Researchers believe tea’s natural compounds — including catechins and flavonoids — may help support bone formation while slowing bone breakdown. These compounds are found in several types of tea, especially green tea.
The study suggested that even small improvements in bone density could potentially reduce fracture risk at a population level, particularly among older women who are more vulnerable to osteoporosis.
Heavy Coffee Consumption May Raise Concerns
While moderate coffee intake did not appear harmful, researchers observed that drinking more than five cups of coffee daily was associated with lower bone density. The link appeared stronger among women with higher lifetime alcohol consumption.
Scientists noted that caffeine may interfere slightly with calcium absorption and bone metabolism, although the effect is considered relatively small. Some experts added that consuming coffee with milk could help offset part of this impact.
Importantly, the researchers stressed that the findings do not prove that tea directly improves bones or that coffee causes osteoporosis. Instead, the results show an association that may help guide healthier lifestyle habits in ageing populations.
Researchers Urge Balance, Not Extreme Changes
The study authors cautioned against making dramatic dietary changes based on the findings alone. Associate Professor Enwu Liu of Flinders University said the results should be viewed as one part of overall bone health management.
Researchers emphasised that calcium, vitamin D, regular exercise, and healthy lifestyle habits remain the most important factors for maintaining strong bones and reducing osteoporosis risk. Tea may simply offer an additional supportive benefit when consumed in moderation.
Why Osteoporosis Remains a Major Concern
Osteoporosis affects millions of women worldwide, especially after menopause, when bone density naturally declines. The condition increases the risk of fractures in areas such as the hip and spine, often leading to reduced mobility and quality of life.
With coffee and tea among the most widely consumed beverages globally, researchers say understanding how these drinks influence long-term bone health could help improve preventive care strategies for older adults.
