In addition, patients with stomach disease or gastric ulcer should not eat food with more oil, because the heavy oil food is difficult to digest, so that the digestive fluid can not directly contact the food, resulting in fullness and dyspepsia after eating. And the original purpose of adding seasoning oil is to increase fragrance to achieve the purpose of attractive appetite. However, when cooking, there is too much grease, which will make people feel greasy and affect people’s appetite.
