A Healthy Skeleton Benefits from Tea
Several decades ago, several scary articles received a great deal of publicity.16,17 These articles attempted to show that drinking beverages containing caffeine somehow could weaken a woman’s bones. — Wrong! — The real story: three more recent studies proved that the earlier articles had shown that women who drank even large amounts of beverages containing caffeine experienced reductions in bone density only if they also were deficient in calcium or vitamin D!18-20 In fact, research shows that caffeine intake has no effect on bones in anyone at any age.19,20
Drinking at least 2 cups of phytonutrient-packed black or green tea every day enhances bone health and strength. This was shown most powerfully in the 91,465 postmenopausal women who participated in the U.S. government’s Women’s Health Initiative study.21 The results of this study, published in the American Journal of Epidemiology make it quite clear that instead of avoiding tea, women who drink at least 2 cups of tea every day can enjoy optimized bone mass throughout their bodies, and especially in parts of the vertebral spine.
