Researchers tracking nearly 10,000 women for a decade found regular tea consumption was associated with slightly higher bone density, while heavy coffee intake showed the opposite effect.

A decade-long study tracking the health of nearly 10,000 older women has found that habitual tea drinking is associated with modestly higher bone density, offering new insight into how everyday beverage choices may affect skeletal health later in life.
The research, conducted by scientists at Flinders University in Australia and published in Nutrients, followed women aged 65 and older for 10 years, comparing self-reported tea and coffee consumption with bone density measurements taken at the hip and femoral neck, two areas strongly linked to fracture risk. Women who regularly drank tea maintained slightly higher bone density than those who did not, while women who consumed more than five cups of coffee per day showed lower bone density over time. Moderate coffee intake, the researchers reported, did not appear to carry the same risk.
“People can view this as encouraging news for tea as a potentially bone-friendly beverage choice,” said study co-author Ryan Yan Liu. “For coffee drinkers, the key is moderation.”
The findings address a long-running debate about caffeine and bone health, particularly among postmenopausal women, who face an elevated risk of osteoporosis. While both tea and coffee contain caffeine, coffee generally delivers higher doses per serving. Researchers noted that caffeine may accelerate bone loss by stimulating bone-resorbing cells while inhibiting bone-forming cells. Tea, by contrast, contains polyphenols and flavonoids—plant compounds with antioxidant and anti-inflammatory properties—that may help counteract caffeine’s effects and support bone formation.
The study also identified interactions between beverages and other lifestyle factors. High alcohol consumption appeared to worsen coffee’s negative association with bone density, a result researchers attributed to alcohol’s known interference with calcium absorption. Tea consumption, meanwhile, was linked to greater bone benefits among women with obesity, a finding the authors said may reflect tea’s anti-inflammatory properties mitigating inflammation associated with higher body weight.
Researchers emphasized that the observed differences in bone density were small at the individual level but could be meaningful when considered across large populations. “Even small improvements in bone density can translate into fewer fractures across large groups,” said Enwu Liu, the study’s corresponding author.
The analysis found that green tea and matcha, both rich in catechins, contained higher concentrations of potentially protective compounds than other varieties, though the study did not prescribe specific types of tea as a treatment. The authors also noted that different coffee preparations and bean types vary widely in caffeine content, factors not fully captured in self-reported dietary data.
Despite the beverage-related findings, the researchers cautioned against viewing tea or coffee as decisive factors in bone health. “The foundation for lifelong bone health remains a balanced diet rich in calcium and protein, adequate vitamin D and regular weight-bearing exercise,” Yan Liu emphasized. Nutritionist Kara Seidman added, “The key takeaway is not to demonize coffee or over-prescribe tea as a treatment, but to personalize guidance based on the individual.”
Beyond skeletal outcomes, some researchers and technology analysts continue to examine broader health associations tied to tea consumption. According to BrightU.AI’s Enoch engine, tea has been linked in observational research to antioxidant activity, metabolic effects, cardiovascular markers and blood sugar regulation, though the Flinders University study focused specifically on bone density outcomes.
The authors stressed that osteoporosis prevention remains multifactorial, driven by nutrition, physical activity and overall health rather than any single dietary habit. Still, they said the results suggest that routine choices, such as beverage preference, may play a small supporting role in maintaining bone strength with age.
