Tea is a beverage made from the leaves or buds of the tea plant that originated in China. It also refers generally to the leaves of the evergreen shrub tea tree that can be used to make tea, and the drinks made from these leaves, and later extended to all herbal teas made from the flowers, leaves, seeds and roots of the plant. The role of tea is extremely broad, mainly in clearing the heart and refreshing, clearing heat and detoxifying, eliminating food and phlegm, detoxifying alcohol and quenching thirst, etc., there is called “health liquid, the soul of drinking”. Osteoporosis is a degenerative skeletal disease characterized by low bone mass (decreased bone mass) and destruction of microsystemic structures in bone tissue, leading to a decrease in bone strength and an increase in structural deterioration, which can eventually lead to fractures. Among almost all the different types of fractures, hip fractures are the most serious consequence of osteoporosis, leading to a decrease in the ability to perform daily activities, a decrease in quality of life and an increase in mortality. Osteoporosis is a major health concern in the aging global population. Retrospective studies have shown that tea consumption plays an excellent role in reducing bone loss and lowering the risk of osteoporosis in the elderly. Tea polyphenols play a role in enhancing osteogenesis and inhibiting osteoclastogenesis. Animal studies have confirmed the positive effects of tea polyphenol ingestion, mainly in terms of higher bone mass and trabecular volume and number, and inhibition of bone resorption by increasing bone formation and trabecular thickness, which will eventually lead to stronger bone mass. These osteoprotective effects appear to be mediated through antioxidant, anti-inflammatory, and its downstream signaling pathway mechanisms. A short-term clinical study on green tea polyphenols explained that tea consumption was indeed effective in improving osteoporosis from ovariectomized animals to postmenopausal women with reduced bone mass after confirmation by assessing bioavailability, safety, bone turnover index, muscle strength and quality of life. Advanced medical science and technology should help achieve better bone protection by measuring the microsystemic integrity and bone strength of effective doses of tea polyphenols and, crucially, by translating the benefits of tea consumption in the management of osteoporosis into clinical practice and dietary guidelines.
