But many people say that overnight tea can't be drunk, which will cause cancer. Will Pu 'er cause cancer overnight? The answers are all in the content of this article. Please read this article in detail! The weight-reducing and lipid-lowering effects of Pu 'er tea mainly come from two aspects: First, it is formed by the comprehensive action of tea polyphenols, chlorophyll, vitamin C and other effective components (the tea polyphenols content in Yunnan tea-producing areas are all 30-34%, the total catechin content is 18-24%, and its foam resistance and tea extract are 46-50%). The second is the comprehensive effect of various beneficial bacteria formed in the fermentation process (the effect of bacteria can reduce the absorption of triglycerides and sugars in the small intestine and improve the decomposition of waist and abdomen fat by enzymes). A cup of Pu 'er tea after each meal can effectively stimulate your metabolism and accelerate fat decomposition.
A cup of Pu 'er contains only about 4 calories, and drinking pure Pu 'er is regarded as the most effective and healthy way to lose weight. Caffeine in Pu 'er tea can help burn excess fat in the body, while tea polyphenols rich in Pu 'er tea can effectively decompose fat. Pu 'er tea is different from other teas because it will produce special compounds after special fermentation treatment. This special substance is called highly polymerized theabrownin. Experiments show that drinking Pu 'er tea for one month can significantly reduce blood lipid and blood sugar. Highly polymerized theabrownin in Pu 'er tea can reduce blood lipid.
But? It is circulated on the Internet that Pu 'er tea contains secondary amines overnight, which can be converted into carcinogenic nitrosamines. If you drink too much, you will get cancer. In fact, this statement has no scientific basis. Secondary amines are mostly found in pickled products, and nitrosamines are also found in bread, vegetables and meat. When the intake of nitrosamines reaches 0/00 to 2000 mg/kg body weight/kloc-,it may cause cancer. Generally, normal food intake will not cause cancer. Therefore, it is unscientific to say that drinking overnight tea causes nitrosamines to cause cancer. On the contrary, tea contains tea polyphenols and vitamin C, which can inhibit nitrosamines. Moreover, tea polyphenols can also scavenge oxygen free radicals and inhibit other carcinogens. ? Actually, it won't, but research shows that tea polyphenols will be further oxidized after tea leaves are soaked, and the color of tea leaves will deepen if they are left for too long. Tea polyphenols in tea will be oxidized into yellow-red and reddish-brown oxides. These oxides are non-toxic and will not cause harm to human body.
Overnight tea has no toxic effect as long as it does not deteriorate. However, there is no clear research to show whether Pu 'er tea can lose weight overnight, but don't drink it after brewing for more than 12 hours. Tea leaves over 12 hours will produce harmful bacteria. However, overnight tea has a good effect on eliminating bad breath, whitening teeth and protecting gums. So far, there is no experimental proof? There is no evidence that drinking Pu 'er overnight will cause cancer. MM who wants to lose weight should choose an effective and healthy way to lose weight. While choosing tea to lose weight, they hope to cooperate with proper exercise and proper diet control, and don't overeat during weight loss. (The content is for production test only)
