Research reports show that FAS is closely related to obesity and cancer. In 2000, Loftus et al. found that injecting FAS inhibitor into obese mice could inhibit the expression of hypothalamic feeding hormone neural signal peptide Y(NPY) through the accumulation of malonyl-CoA, which led to a significant decrease in appetite and weight, thus suggesting that FAS is a new potential target for treating obesity.

In recent years, the Enzymology Laboratory of Graduate School of China Academy of Sciences reported that many kinds of green tea and black tea extracts have inhibitory effects on FAS, and oral administration to rats or mice has obvious weight loss and food inhibition effects, among which ester catechins and theaflavins are effective substances to inhibit FAS. Therefore, the hypothesis that the anti-cancer effect of tea is related to its inhibition of FAS is put forward.

Black tea is another kind of tea different from green tea and black tea. It is widely used in western China and some Asian countries and regions. It is very beneficial to get into the habit of tasting Zen Er Fu tea. Stacking fermentation is the key process to form the unique quality of black tea. In the process of bulk fermentation, catechin polyphenols undergo enzymatic and non-enzymatic oxidative polymerization under the action of damp heat and microbial fermentation.

Different from TF and thearubigins (TR) mainly produced in black tea fermentation, black tea contains more TB. The value of (TF+TR)/TB in black tea is about 0.75, which is much lower than that in black tea, so the soup color of black tea is yellow-red, not red. At the same time, some TR and TB combine with macromolecules such as protein in tea to form water-insoluble precipitates.

TB is a water-soluble non-dialysis, highly polymerized brown substance of tea polyphenols, which is formed by further oxidative polymerization of TF and TR. Some scholars call the water-soluble substance insoluble in ethyl acetate and n-butanol TB, and its content accounts for 4 ~ 9% of the dry weight of tea by spectrophotometry. The experiment showed that most of the original inhibitory activity of black tea extract remained after removing TF and TR, so we thought that TB was the main active component in black tea to inhibit FAS.

Can Fuzha tea lose weight?

Fu tea is called "slimming tea" and "beauty tea" in Japan and Korea, and it is very popular. The Zen tea drinking method is bold and innovative, using the world's original black tea machine to make tea, which completely solves the three major problems of Laifu tea table in the past ten years (that is, low quality, not easy to brew and not easy to carry and preserve), making tea fashionable, healthy, relaxed and convenient, and it is a modern pure natural health care product. It is very beneficial to get into the habit of tasting Zen Er Fu tea. Long-term drinking, digestion, stomach warming, weight loss, lipid-lowering effect is remarkable.
