Eating protein exhaust is mostly related to factors such as difficulty in digesting food and imbalance of intestinal flora. Protein is a relatively difficult food to digest, because of the increased difficulty of food digestion, so the time spent in the intestine will be relatively long, the irritation caused to the intestine is also more, many people will exist after eating the increased number of exhaust. When protein is digested, it needs to be broken down by proteases in the body. If you eat a lot of protein-based food for a long time, the proteases in your body will be reduced accordingly, or even depleted, and then you will not be able to break down and absorb the protein. At the same time protein in contact with harmful bacteria, will also produce more gas. Although protein foods are more nutritious, but in the digestion, but will cause changes to the intestinal flora, long-term eating protein is not conducive to the survival of beneficial bacteria in the intestinal tract, but will lead to harmful bacteria will proliferate, resulting in increased exhaust performance.
