Tea may strengthen bones in older women; heavy coffee could weaken them

A 10-year study of nearly 10,000 women aged 65+ found tea drinkers had slightly higher hip bone density, while consuming more than five cups of coffee daily was linked to lower bone density; moderate coffee (about 2–3 cups) showed no harm. The effects are small, tea catechins may help bone formation, caffeine can affect calcium metabolism, and calcium/vitamin D remain central to bone health, with no need for drastic daily changes.
