The so-called sharing method means that when eating, protein and starch are eaten separately. Proponents of food separation believe that the time to digest these two molecules is different, because the human digestive system needs 6 to 8 hours to decompose protein and 3 to 4 hours to decompose starch. So if protein is always mixed with starch, the stomach will secrete different gastric enzymes to digest these two ingredients respectively, and the digestive system will be very hard. When the digestion is incomplete, after that, the food you eat will easily turn into fat (if you start eating food before the digestion is completed, it will not only increase the burden on the digestive system, but also make the incompletely digested food accumulate in the body and gradually turn into fat).
This statement is unreasonable. First of all, the absorption processes of protein and starch are different, and they are decomposed and absorbed by different enzymes. These enzymes do not interfere with each other, and the secretion of one enzyme does not affect the other. Secondly, if digestion is not completed, it will not be absorbed, and the body will not be able to use these nutrients, of course, there will be no transformation of substances in the body.
