He Yuqi (first from right) is treating the patient. During the Spring Festival, Wang Peng, a member of the Xinhua News Agency, met frequently with friends and relatives, and the delicious food on the table was constantly tempting. At the same time, we should pay more attention to the health of the digestive system. How to protect the health of our digestive system? Recently, the Department of Gastroenterology and Digestive Endoscopy Center of Beijing Chest Hospital affiliated to Capital Medical University opened a clinic. Our reporter interviewed Professor He Yuqi, the director of the Department of Gastroenterology of the hospital, to explain the precautions for digestive system health. The diet adjustment was just like many netizens' joke at that time - "When you gain three pounds during the holiday season, you should be careful about digestive diseases". Just after the Spring Festival holiday, the Department of Gastroenterology has become one of the popular departments for patients to visit. "To some extent, most digestive tract diseases are eaten." He Yuqi reminded that during the Spring Festival, due to the obvious increase of large fish and meat in the diet and less intake of vegetables, it is easy to lead to a high incidence of digestive tract diseases. After the festival, attention should be paid to adjusting the diet structure to protect the health of the digestive system. How should I adjust my diet? "Eat less and eat more meals, mainly digestible food, and eat more vegetables, staple food and meat in an appropriate amount. Pay attention to light, less salt and less greasy." He Yuqi reminded that eat less animal fat and viscera, such as egg yolk, caviar, and fat, which contain more cholesterol, should not be consumed by people with high cholesterol. At the same time, do not eat spicy, stimulating, raw and cold food, drink less alcohol, strong tea and coffee, and avoid greasy dinner. How important is good eating habits? According to experts, some research shows that in 2017, about 10 million of the world's total adult deaths were caused by bad eating habits, among which 5 million were among people under the age of 70. "This figure accounts for about 22% of the world's total adult deaths, which is close to the number of deaths caused by smoking." He Yuqi said. What are the common bad eating habits? "Eating irregularly, overeating, eating fast, eating spicy, greasy, sweet, hot or cold food, drinking a lot of alcohol for a long time, etc." He Yuqi said that to prevent digestive tract diseases, we should pay attention to light diet, and do a good job of dietary adjustment from three aspects of low salt, low fat and low sugar; Ensure sufficient intake of fresh fruits and vegetables, and pay attention to dietary diversity; Choose reasonable cooking methods. Although the food made by frying, frying, grilling and other cooking methods tastes good, it is not healthy. More gentle cooking methods should be selected, such as steaming, boiling and other methods can not only better retain the nutrition of the food, but also do not produce harmful substances. Early diagnosis and early treatment should not be delayed. "Food passes through the chewing and swallowing of the mouth, through the esophagus, stomach and duodenum, which is the upper digestive tract, and then through the jejunum, ileum and colorectal, and finally excreted in the form of faeces. The organs outside the digestive tract such as liver, gallbladder and pancreas also participate in the digestive process." He Yuqi said that common digestive system diseases include gastroesophageal reflux, gastritis, peptic ulcer, hepatobiliary disease Pancreatic diseases, intestinal diseases, etc. In addition, there are many kinds of digestive tract tumors, including benign tumors and malignant tumors.
