1, high-protein and high-nutrient foods are taken in too much, which can't be fully digested and absorbed by the human body, and a large amount of indole is produced in the metabolic process in the body, which often causes the stool to smell too smelly. This situation often happens to young people. The solution is to eat reasonably and not to eat too much meat, chocolate and other foods.

2, intestinal aging causes the stool to be too smelly: This situation often happens to middle-aged and elderly people, and sometimes even a heavy tar smell can be smelled, but now many young people do not pay attention to their diet, which will lead to the phenomenon of intestinal aging ahead of schedule. The solution is to eat a reasonable diet, eat some detoxified natural foods, such as black fungus, etc. Take less drugs that stimulate the intestines, and clean the intestines once in a while.

3. People with dry stools, who defecate once every few days, have a bad smell. The reason is that the waste can't be excreted in time, and it accumulates in the intestine for too long, resulting in too much waste. At this time, a large number of toxic substances adhere to the intestinal wall and are easily absorbed by the human body. The solution is: eat more fiber-rich vegetables and fruits, develop the habit of regular stools, and defecate in time.
