Which is the best deoiling effect, coffee or tea?

Sometimes eating too greasy feels very uncomfortable, some people say that drinking strong tea can relieve greasy, some people say that drinking coffee can relieve greasy, so which one is more able to solve greasy ah? Do the alkaloids in tea and some substances in coffee have an effect on the digestive tract?

Netizens explained: scientific Squirrel member True Land Bird believes that if the food mass in the stomach is high in fat, it will generally promote gastric emptying (physiological terms). But this does not mean that there are chemical receptors in the stomach that can make the cerebral cortex feel "so tired in the stomach". It is just pure humoral regulation and does not involve neuroregulation. Therefore, drinking tea or coffee can not greatly change the proportion of food mass fat in the stomach, but gargle to remove the oil in the mouth. The member "magnet" agrees that drinking tea or coffee is just like eating watermelon to remove oil, just to refresh the mouth. I'm afraid I can only eat crude fiber to get rid of the greasy in my stomach.

Li Xinghui, director, professor and doctoral supervisor of the Tea Science Research Institute of Nanjing Agricultural University: tea is better at relieving greasy. Because tea contains a large number of tea polyphenols and other antioxidants, which is conducive to reducing fat; the caffeine in tea helps to accelerate excretion; tea is more clear drink, itself does not contain greasy ingredients. Coffee contains chlorogenic acid and other antioxidants, which is conducive to reducing fat; the amount of caffeine in coffee is generally lower than that in tea, and the diuretic effect is also different. Coffee roasting itself will produce oil, and coffee is often drunk with milk and sugar. "Iron absorption stone" said to eat crude fiber to resolve greasy view is wrong, can only take exercise consumption and accelerate decomposition and excretion methods.
