High daily coffee intake linked to lower bone density in older women, tea may boost bone health

A Flinders University study published in Nutrients followed 9,704 postmenopausal women aged 65+ for 10 years and found that consuming more than five cups of coffee daily was associated with lower bone mineral density at key sites, while tea consumption correlated with higher total hip BMD; moderate coffee (about 2–3 cups/day) showed no negative effect. The researchers noted interactions with alcohol and obesity and stressed the study shows associations, not causation. They advised maintaining bone health through calcium and vitamin D, physical activity, and avoiding smoking and heavy alcohol, with a note that moderate coffee is acceptable and tea may be a bone-friendly alternative.
