Eating garlic fart odor belongs to a normal phenomenon, it does not matter whether it is a good phenomenon or a bad phenomenon. Garlic has allicin, which is a stimulating substance that promotes intestinal peristalsis, thus causing the body to fart. When there are protein substances in the body that are not thoroughly digested, they are discharged, which can lead to smelly farts. Furthermore, garlic has a high amount of sulfide, which is absorbed and digested in the intestines and is broken down to form hydrogen and carbon dioxide, which can also cause smelly farts. Garlic is very popular as a seasoning to make food taste delicious. However, garlic should not be consumed in excess, so as not to irritate the mucous membrane of the gastrointestinal tract and cause gastrointestinal discomfort.
