Habitual tea drinking could lead to higher bone density, particularly for women, and lower the risk of bone fractures, the research conducted by chinese School of Public Health with Peking University found,450,000 adults.

Although little is known about the cause of the association daily consumers of green tea and those who had drunk tea for more than 30 years have a lower rate of fractures according to their hospitalization records.

The paper on the research was published on the international journals of Nutrients and Osteoporosis International.

Prof Li Liming, research head , said the study included 453,625 people randomly selected from the China Kadoorie Biobank, and documented their records on hospitalized fractures. Based on their self-reported tea consumption, the researchers found that compared with those who do not drink tea, daily tea consumers have a 12 percent lower risk of fracture. Those who drink green tea or have drunk tea for over 30 years have a 20 to 30 percent lower risk in hip bone fracture.

Li said bone density has become an important subject of public health. Previous researches also suggested a certain

association between habitual tea drinking and higher bone density among menopausal women.

He said the prospective study still needs a more substantial sample analysis for more accurate results linking the association between tea drinking and bone density, since tea drinking may affect other factors such as improving people's concentration and vigilance.

Tea consumption, 120 mL/d or more for 1 year, significantly reduces the risk of developing hypertension in the Chinese population.

Tea has long been believed to possess hypotensive effects in popular Chinese medicine. We examined the effect of tea drinking, measured in detail for the past decades, on the risk of newly diagnosed hypertension in 1507 subjects (711 men and 796 women), 20 years or older, who did not have a hypertensive history during 1996 in Taiwan. Six hundred subjects (39.8%) were habitual tea drinkers, defined by tea consumption of 120 mL/d or more for at least 1 year. Compared with nonhabitual tea drinkers, the risk of developing hypertension decreased by 46% for those who drank 120

to 599 mL/d and was further reduced by 65% for those who drank 600 mL/d or more after carefully adjusting for age, sex, socioeconomic status,  family history of hypertension, body mass index, waist-hip ratio, lifestyle factors (total physical activity, high sodium intake, cigarette smoking, alcohol consumption, and coffee drinking), and dietary factors (vegetable, fruit, unrefined grain, fish, milk, visible-fat food, and deep fried food intake). However, tea consumption for more than 1 year was not associated with a further reduction of hypertension risk. 

The benefits of green tea have been discussed by doctors and health experts. . Along with cutting down on sugar, it is believed to aid fat-burning, boost metabolism among other benefits.   The

paper on the research was published in  the journal Nutrients and Osteoporosis International.  Bone density had become an important subject of public health. Previous researches also suggested a certain association between habitual tea drinking and higher bone density among menopausal women.

Celebrity nutritionist Rujuta Diwekar shared her views on green tea, she shook everybody's faith in this wonder-drink.

Prof Li Liming said the prospective study still needs a more substantial sample analysis for more accurate results linking the association between tea drinking and bone density, since tea drinking may affect other factors such as improving people's concentration and vigilance.
