Drinking brick tea for a long time to prevent fluorosis
The use of old tea, old stem fermented and pressed brick tea, its fluorine content is more than a few times that of ordinary tea, long-term drinking may lead to bending back, kidney damage.
In areas where drinking tea-type fluorosis is widely prevalent, children aged 8 to 15 years mainly show fluorosis. Adults over the age of 16 mainly have fluorosis and skeletal fluorosis. The detection rate of skeletal vertebrae at the age of 40 rises rapidly. The high was 43.75%. By the age of 45, the detection rate of fluorosis was even higher, reaching 71.88%. The topic “Drinking tea fluorosis epidemiology research†recently completed by the Center for Disease Control and Prevention of the China Center for Disease Control and Prevention, which is affiliated with Harbin Medical University, further grasped the disease severity, epidemiological characteristics, influencing factors, and fluoride intake and fluorosis. Disease dose response relationship.
According to Professor Sun Dianjun, the person in charge of this project, in all living organisms on the earth, the content of fluorine in tea is the highest, and the more the poor quality tea stored for a long time, the higher the fluorine content. The use of old tea, old stem fermented brick tea, its fluorine content higher than ordinary tea several times, higher than high-quality tea hundred times. Drinking such brick tea for a long time will lead to chronic accumulation of poisoning of the body, which can damage the bone tissue. When the person is severely bent, it can not stand upright. It also affects many tissues and organs in the body, especially the damage to the kidney.
The results of this survey indicate that the distribution range of tea drinking fluorosis accounts for nearly 1/2 of the country's total, and is more common in ethnic minority areas such as Inner Mongolia, Tibet, Sichuan, Qinghai, Gansu, and Xinjiang. Residents of wards in the ward daily fluoride intake ranged from 8.05 to 14.77 milligrams and more than 90% came from brick tea. Among them, drinking tea-type adult skeletal disease is heavier than drinking water-type wards, X-ray imaging features are mostly osteoarthrotic lesions, with varying degrees of osteosclerosis, interosseous membrane changes, and ligament junctions. Calcification and other situations.
