Health hazards behind dinner.
First, induce digestive tract diseases. Zhang Ding said, eat kebabs, grilled fish, seafood and so on. Excessive drinking and overeating at night will increase the burden on the gastrointestinal tract and may even lead to acute pancreatitis. Hideo Suda, a Japanese medical scientist, found that the epithelial cells of gastric mucosa are updated every 2-3 days, and this process is carried out at night, which affects the mucosal repair if eaten too late.
Second, it is related to some cancers. In March this year, a joint study by the Chinese University of Hong Kong and utrecht university, the Netherlands, found that the risk of breast cancer increased by 80%, 10 ~ 12, 0 ~2 and 2 ~4 in the evening, 120% and 90% respectively. Women who eat at night for 20 years or more (at least once a week after 10 pm) have an increased risk of breast cancer 128%. According to scientists' analysis, eating late at night may affect the secretion of insulin, melatonin and cortisol, leading to metabolic problems highly related to breast cancer. Zhang Ding said that barbecue supper in particular may contain benzopyrene carcinogens. Eating once or twice occasionally won't do much harm, but eating regularly will increase the risk of cancer.
Third, it affects metabolic function. Cui Jun, director of the Nutrition Department of Nortel Hospital, said that at night, people's metabolism drops, and their calorie consumption decreases, so eating supper can easily lead to obesity. According to the latest research of perelman Medical College of the University of Pennsylvania, compared with eating dinner before 7: 00 p.m., eating supper at night 1 1 will make the body store more fat, which will lead to the increase of fasting blood glucose, insulin, cholesterol and triglyceride levels, and increase the risk of diabetes and heart disease.
Fourth, it affects nerve function. A study by the University of California found that eating late at night is harmful to brain health and memory. Zhang Guanghuan said that Chinese medicine believes that "the stomach is not harmonious, so it is difficult to sleep." Organs in the body "work overtime" in order to digest and absorb food. As a "commander", the brain has no rest, and the excitement is enhanced, which is easy to cause insomnia.
The "golden eating method" of midnight snack
Zhang Ding pointed out that it is not recommended for everyone to eat supper. If you are hungry at night, you can replenish energy moderately and don't eat it as a dinner. If you must eat supper, you need to pay attention to a balanced diet and grasp three principles.
Don't eat supper 2~3 hours before going to bed. Zhang Ding pointed out that the peak of digestion and absorption of sugar in gastrointestinal tract is about 2 hours after meals. If you eat fat, this time needs to be delayed. Therefore, the interval between supper and sleep should be at least 2 to 3 hours, and it is best not to eat supper after 9 pm.
