High coffee consumption is linked to lower bone density in older women, while daily tea drinking may offer protective benefits.
Health outcomes shifted noticeably based on what subjects chose to drink each day.
Women who drank more than five cups of coffee daily showed significantly lower bone mineral density.
Conversely, regular tea drinkers demonstrated higher density in their hip bones.
Moderate coffee drinkers who consumed two to three cups saw no negative impact on their skeleton.
Over the course of a ten-year study, Flinders University researchers monitored the drinking habits of more than 9,700 senior women.
Focus was placed on assessing bone mass in the hip and femoral neck—the two regions most vulnerable to osteoporosis-related damage.
Other habits altered these risks further. High alcohol consumption combined with heavy coffee drinking led to the lowest density scores at the femoral neck.
Meanwhile, women living with obesity experienced the strongest protective benefits from drinking tea, according to the New York Post.
Breakdown and buildup
Osteoporosis triggers painful fractures in one out of three women over age fifty worldwide.
A lower starting bone mass combined with rapid post-menopausal bone loss puts older women at the highest risk.
Chemical compounds explain this striking divide between brews.
“Compounds called catechins, abundant in tea, may promote bone formation and slow bone breakdown,” study co-author Ryan Liu told ScienceDaily, cited by the New York Post.
Caffeine works differently inside human tissue.
“Coffee’s caffeine content, by contrast, has been shown in laboratory studies to interfere with calcium absorption and bone metabolism, though these effects are small and can be offset by adding milk,” Liu said.
Keeping perspective
Medical experts urge readers to keep these findings in proper context without panicking.
Observational tracking reveals population patterns rather than direct cause and effect.
“Our results don’t mean you need to give up coffee or start drinking tea by the gallon,” Liu added.
“But they do suggest that moderate tea consumption could be one simple way to support bone health and that very high coffee intake might not be ideal, especially for women who drink alcohol.”
Core lifestyle choices still offer the strongest defense against bone decay.
Protecting your skeleton still relies on conventional wisdom: regular exercise, avoiding tobacco and heavy drinking, and maintaining sufficient levels of calcium and vitamin D.
“The bottom line for the public is reassuring: Moderate coffee intake appears fine, and there is no need to switch drinks for the sake of your bones,” Lisa Young, registered dietitian and adjunct professor of nutrition at New York University, told Fox News Digital, cited by the New York Post.
“The most proven ways to protect bone health remain getting enough calcium and vitamin D, staying physically active and avoiding smoking and excess alcohol,” she added.
“With that said, I do make a case for moderate amounts of coffee for good health. Too much of anything is never a good thing.”
