Coffee and tea are everyday drinks for millions of people, but a new study suggests they may not have the same relationship with bone health. Researchers at College of Medicine and Public Health, Flinders University, Adelaide, followed nearly 10,000 women aged 65 and older for 10 years to examine whether their coffee and tea habits were linked to changes in bone mineral density (BMD), an important measure of osteoporosis risk. The study found that tea drinkers had slightly higher total hip BMD than women who did not drink tea. Coffee showed a different pattern. Moderate consumption was not associated with harm, but women drinking more than five cups a day had lower bone density. The researchers stress that the differences were modest and do not mean older women need to give up coffee. The reasearch paper, 'Longitudinal Association of Coffee and Tea Consumption with Bone Mineral Density in Older Women: A 10-Year Repeated-Measures Analysis in the Study of Osteoporotic Fractures', was written by Ryan Yan Liu and Enwu Liu and published in Nutrients in November 2025.
TEA DRINKERS HAD SLIGHTLY HIGHER BONE DENSITY
