Garlic has antiseptic and anti-inflammatory effects, cleanses the intestinal tract, detoxifies and reduces sugar, and protects the heart and brain vessels. Garlic has a pungent taste, and according to its nutritional composition, there are two main reasons for more intestinal exhaust after eating garlic: First, garlic is a result of stimulation of the gastrointestinal tract, which is relatively strong, and the response of the gastrointestinal tract to this stimulation is to accelerate gastrointestinal peristalsis, so that the original gas in the gastrointestinal tract is quickly expelled from the body. Secondly, garlic contains substances that can produce gas. The main components of garlic are allicin and volatile oil, which can produce more carbon dioxide, hydrogen sulfide and other gaseous substances through decomposition after entering the body, and allicin can also react with other foods to produce other gases, which can increase the amount of gas produced in the intestines and cause discomfort such as exhaust.
