A 10-year study of nearly 10,000 women (65+) found that tea drinkers had slightly higher bone density than non-tea drinkers. Tea’s polyphenols and flavonoids may counteract caffeine’s bone-weakening effects by promoting bone formation and reducing inflammation. Excessive coffee intake (5+ cups/day) was linked to lower bone density. Moderate coffee consumption appeared safe, but alcohol worsened coffee’s negative effects on bones by disrupting calcium absorption. Women with obesity saw greater bone benefits from tea, likely due to its anti-inflammatory properties countering weight-related inflammation.
