In life, some people eat a lot of food (nutrition), but they are not fat, so it is easy to draw the conclusion that the nutrition he eats is "not absorbed". There are still some people who sell products that use "absorb well" to make a fuss. How can I know if the food (or nutrients) I have eaten is absorbed?

　　The method cannot be easier. Because the food (or nutrition) we eat can only have two results: it is either absorbed (entered into the blood) or excreted (formed stool), and there will be no third channel. Therefore, if food (or nutrients) are not absorbed, then it will definitely be excreted from the feces, then the amount of feces or the frequency of defecation will increase abnormally, on the contrary, if the excretion of feces is normal (traits, quantity or frequency Are normal), that means food (or nutrition, especially the three major nutrients) is well digested and absorbed. In other words, you can know whether the absorption of food (or nutrients) is normal by seeing whether the excretion is normal. Generally, unless there is more frequent diarrhea (increased frequency of defecation), the digestion and absorption of food (or nutrition) is normal. Food (or nutrition) cannot be digested and absorbed, which is a rare situation.

　　How to explain the phenomenon of "dry eating not fat" mentioned earlier? In fact, it is often not because of "not absorbed", but because of his higher basic metabolism and higher consumption .
