  • Researchers analyzed coffee and tea consumption and changes in bone density among 9,704 women aged 65 and older over about 10 years.
  • More than five cups of coffee a day was associated with lower bone density, while two to three cups was not; tea drinkers tended to have higher hip bone density.
  • Researchers said tea catechins may support bone formation, while caffeine may affect calcium absorption and bone metabolism, although its effect may be small.

Women aged 65 and older who drink more than five cups of coffee a day may be more likely to have lower bone density, a study has found.

Researchers at Australia’s Flinders University analyzed the coffee and tea consumption of 9,704 women and tracked changes in their bone density for about 10 years. They examined the upper thigh bone and the hip.

Catechins, which are abundant in tea, may help bone formation and slow bone breakdown.

· Ryan LiuThe study’s co-author explained why tea consumption may be linked to higher bone density.

Women who drank more than five cups of coffee daily showed a tendency toward lower bone density. By contrast, drinking about two to three cups a day was not associated with reduced bone density. Women who drank tea tended to have higher hip bone density.

Study co-author Ryan Liu said catechins, which are abundant in tea, may help bone formation and slow bone breakdown. He said caffeine in coffee could interfere with calcium absorption and bone metabolism, though the effect may be small.

Caffeine can interfere with calcium absorption and bone metabolism.

· Ryan LiuLiu described a possible mechanism behind the association between heavy coffee consumption and lower bone density.
