Eating fruit immediately after meals will increase blood sugar concentration. After dinner, it has become a "program" in many restaurants. Many people think that eating fruit after meals can relieve some greasy and help digestion. However, Professor Zhang from the Health Room of Beijing University of Chinese Medicine believes that eating more fruits immediately after a full meal will increase the blood sugar concentration and increase the burden on the pancreas. In the long run, it will become one of the causes of diabetes. Professor Zhang explained that apples and other fruits really help digestion. If you only eat seven or eight minutes full and eat some fruit, you can supplement vitamins and help digestion. However, after a hearty meal, especially after a banquet, people have eaten a lot of high-protein, high-fat and high-calorie foods, and some people have drunk a lot of wine and are full. Eating more fruits immediately at this time will increase the intake of calories and sugar and raise blood sugar. Moreover, after food enters the human stomach, it must be digested for an hour or two before it can be discharged slowly. If people eat fruit immediately after meals, they will be blocked in their stomachs by indigestible fat and protein that arrive early. If the fruit stays in the stomach for too long, it will affect the digestive function and feel flatulence. Professor Zhang said that the best time to eat fruit is one hour before meals and two hours after meals. Because the gastrointestinal tract is empty at this time, water-soluble vitamins and minerals such as vitamin C in fruits can reach the small intestine through the stomach in a short time on an empty stomach, which is beneficial to absorption and can avoid flatulence. Professor peking university health science center and Professor Tong Xiaolin from the China-Japan Friendship Hospital of the Ministry of Health believe that this issue should be treated dialectically and comprehensively. Eating a little fruit after a meal is really refreshing, and it has the effect of cleaning the mouth and cleaning the gastrointestinal tract. Moreover, generally, the amount of fruit eaten after a banquet will not be much, and healthy people themselves have a strong ability to regulate blood sugar, so it is no problem to eat less fruit. However, if you eat a lot of fruit, or if you have high blood sugar or diabetes, you should pay attention. Different individuals are very different and cannot be generalized. They should be different from time to time, from place to place and from person to person. For people with hyperglycemia or diabetes, the most important thing is to do a good job of "total control" of calories and sugar. If you want to eat fruit, you should eat less and eat more. When eating fruit, you'd better choose "green", "raw" and undercooked. This kind of fruit tastes good, but the sugar content will be greatly reduced.
