Garlic is a common condiment in daily life, and there are many benefits to eating garlic. Garlic contains allicin which can play a bactericidal role and enhance the antioxidant power of the body. Garlic is a stimulating food, especially when eaten on an empty stomach, which can cause stomach pain, gastric distension and other uncomfortable symptoms, and may aggravate gastric disease. After eating raw garlic, it can damage the gastric mucosa and reduce the secretion of gastric juice. Some people eat garlic after eating it, which leads to pain and nausea symptoms in the mouth area. Gastric patients should choose light and easily digestible food that will not damage the gastric mucosa, and can eat more food with high fiber content, which can help intestinal peristalsis.
