Garlic is a condiment with anti-inflammatory, antiseptic and anti-cancer effects. Eating garlic in moderation can help improve the body’s immunity and reduce the possibility of stomach diseases. However, since garlic is a stimulating food, it can cause some stimulation to the gastric mucosa when ingested, so avoid eating too much at once, otherwise it will lead to stomach discomfort. Some people who suffer from chronic gastritis are more susceptible to the aggression of the pungent substances in garlic because the protective barrier of the gastric mucosa has been damaged, and they may experience stomach discomfort after eating it. Some people may suffer from gastric ulcer disease, and the excessive secretion of gastric acid will cause stimulation to the ulcer surface, leading to stomach spasm and contraction, thus causing pain in the stomach. People with gastric neurosis should avoid irritating and allergy-prone food in their diet, otherwise it will induce disease attacks. These people will suffer from disease attacks caused by stimulation after eating garlic, which will lead to strong secretion of gastric acid and slow peristaltic movement of the intestines, so they will also experience discomfort such as gastric distension and stomach acidity.
