It is best to eat fruit before meals: First, it is beneficial to lose weight. Eating some fruits every day before meals 1 hour is a simple and effective way to lose weight. Because fruit is rich in sugar, it can be quickly converted into glucose in the body and absorbed by the body to supplement the calories consumed by the body due to physical, mental and mental labor. With the increase of sugar content in blood, it can quickly reduce the brain's response to hypoglycemia, and the crude fiber in fruit can give the stomach a feeling of fullness, thus relieving the body's strong appetite and reducing the demand for high fat and high protein in diet. The crude fiber in fruit can't be absorbed in the body, which is the mystery that eating fruit before meals can effectively lose weight. Secondly, a scientist in Taiwan Province Province emphasized that eating some fruits every day before meals 1 hour is the most beneficial for keeping fit and prolonging life. The reason is that the fruit is raw, and eating cooked food after eating raw food will not produce reactions such as leukocytosis in the body, which is conducive to protecting the human immune system. If you eat fruit after a full meal, it takes 1 to 2 hours for the food to be digested in the stomach, and the fruit is a monosaccharide food, which is easily attracted to the body and does not need to stay in the stomach for a long time; Because fructose can't enter the intestine in time, it will sour in the stomach, produce organic acids and cause bloating. Therefore, eating fruit before meals 1 hour is the most beneficial. You can eat fruit directly for breakfast in the morning ... it is best to eat apples. At noon, it is best to eat grapes and watermelons one hour after meals ... It is best to eat bananas one hour after meals at night, which is helpful for digestion. This is very helpful for people with bad stomachs ... it is customary to think that eating fruit after meals is good. But a few days ago, some scientists put forward different views that eating fruit after meals will lead to long-term disorder of digestive function and easily lead to diarrhea. If you change the time to eat fruit to one hour before meals, you can keep the human immune function normal. If you insist on eating fruit after meals, you must stay for an hour before eating. Many fruits can't be eaten on an empty stomach: after eating a lot of bananas on an empty stomach, they will also combine with hydrochloric acid in the stomach to form a substance that is not conducive to digestion; Persimmon is sweet, soft and delicious, rich in nutrition, but it has astringent effect. Persimmon stone will be formed when it meets gastric acid, which can neither be digested nor discharged. After eating a lot on an empty stomach, symptoms such as nausea and vomiting will appear in light cases, and persimmon stones must be removed surgically in severe cases; Hawthorn contains a lot of tannic acid, and eating it on an empty stomach will stimulate the stomach. Longan fever, hypertension, heart disease patients should not be greedy. Eating fruit half an hour before meals or one hour after meals is beneficial to the absorption of vitamins. If you eat fruit immediately after a meal, you will stay in your stomach for too long, which will affect the absorption of vitamins. Therefore, it is not appropriate to eat immediately after meals. Eating some fruit before meals will reduce appetite and is suitable for people who want to lose weight. Fruits not suitable for eating before meals: tomatoes, persimmons, oranges, hawthorn, bananas, etc. Can't eat on an empty stomach. Tomatoes contain pectin, pectin, soluble astringent and so on. If you eat on an empty stomach, it will combine with gastric acid, increase the pressure in the stomach and cause pain. Persimmon tannin and gastric acid condense to form "persimmon stone". At the same time, patients with gallstones and kidney calculi should be careful when eating persimmons, so as not to worsen their condition. Oranges contain a lot of sugar and organic acids, and it is easy to get bloated and sour when eaten on an empty stomach. Hawthorn tastes sour, and eating on an empty stomach will cause stomach pain; Bananas are high in potassium and magnesium. Eating bananas on an empty stomach will increase the content of magnesium in the blood and inhibit the cardiovascular system. Most people have such a eating habit, that is, eating fruit after meals, whether it is the serving procedure at the banquet or the daily diet of most people. Nutrition experts believe that eating fruit after meals is actually a dietary misunderstanding, which is actually harmful to health and easy to lead to overweight and obesity. At the first academic forum on nutrition, health and sub-health in western China held in Chongqing a few days ago, some nutrition experts said that an important problem affecting the health of China residents at present is excessive calorie intake. Eating fruit after a meal is often based on satiety or overeating, and then adding meals, almost all the calories are stored. On the contrary, eating a certain amount of fruit before meals has many benefits. First of all, many ingredients in fruit are water-soluble, including vitamin C, soluble plant fiber and pectin, which can reduce the cholesterol level in blood. Its digestion and absorption do not need the mixing of complex digestive juices, and it can quickly enter the small intestine through the stomach for absorption. The absorption rate on an empty stomach is much higher than that after meals. Secondly, eating fruit before meals is conducive to grasping the "eight-point fullness" of a healthy diet. Fruit is a low-calorie food, and its average calorie is only a quarter of that of pasta with the same weight, and about a tenth of that of meat such as pork. It is easier to grasp the total intake by eating advanced low-calorie foods. Third, many fruits themselves are easily oxidized and corrupted. Eating fruit first can shorten its residence time in the stomach, reduce the degree of oxidative corruption and reduce the possible adverse effects on the body. Nutritionists suggest that adults should eat fruits before meals (except persimmon and other fruits that are not suitable for eating before meals) from the analysis of the composition of fruits themselves and the characteristics of human digestion and absorption. Children are in a long physical period, and some women belong to the constitution of "spleen and stomach deficiency and cold" in traditional Chinese medicine. It is inappropriate or inappropriate to eat fruit before meals. This group of people can eat fruit once between meals instead of eating fruit immediately after meals. Be patient when reading! You will have unexpected gains! There are all kinds of fruits, pears and peaches in summer and autumn. When people enjoy the rich nutrition brought by fruits, what should they know about the fruit family? As we all know, fruit is not only rich in vitamins, water and minerals, but also higher in fructose and pectin than other foods, which undoubtedly provides sufficient nutrition for people's health. However, someone observed the place where the supermarket sold fruit for nearly an hour, and 30 people bought fruit, of which more than 20 people bought it on impulse. In the survey, we also found that many consumers really don't know much about eating fruit. For example, when choosing fruits, they often lack direction and are more casual. In addition, some consumers don't know the attributes of fruits and how to choose fruits according to their health. At the same time, it is worth mentioning that many women simply take fruit as the staple food to lose weight and beauty. So, is this right? In summer, people eat a lot of watermelon. Watermelon can't be eaten on an empty stomach, because watermelon is a very good food for heatstroke prevention and cooling. From our Chinese medicine, it is dry and cold. In addition, it also contains a lot of water. After you eat on an empty stomach, you dilute your gastric juice, and after the gastric juice is diluted, the gastric acid will be less, which will easily lead to indigestion, loss of appetite, and easily affect gastrointestinal peristalsis. There is mucophenol in tomatoes, which is easy to form insoluble lumps with gastric acid, affecting gastrointestinal function, so it is not suitable for eating on an empty stomach. Fruits that should not be eaten on an empty stomach are bananas, persimmons, oranges, lychees, sugar cane and so on. In the peak season of melons and fruits, people with different constitutions are also very particular about eating fruits. People with deficiency-cold constitution have low basal metabolic rate and less calories in the body, so they should choose warm fruits when eating fruits. These fruits include litchi, longan, pomegranate, cherry, coconut, durian and apricot. On the contrary, people with excess heat tend to have flushing and dry mouth due to their vigorous metabolism, so such people should eat more cool fruits, such as cantaloupe, watermelon, pear, banana, mango, cucumber and tomato. And peaceful fruits, such as grapes, pineapples, apples, pears, oranges, mangoes and plums. People with deficiency cold constitution or excess heat constitution can eat it. Usually when we visit patients, we always like to bring some fruit, but do you know? Not all fruits are suitable for patients, and buying fruits should consider the patient's situation. People with ulcers and hyperacidity should not eat sour pears, lemons, bayberry, plums and other fruits with high acid content to avoid ulcer healing. Asthmatic patients should not eat jujube and other fruits that are easy to produce phlegm and help heat and hinder the function of spleen and stomach. Patients with constipation and hemorrhoids should not eat persimmons, hawthorn, apples and lotus seeds, because these fruits contain more tannic acid, which will stop diarrhea and aggravate the condition. Anemia patients should not eat citrus, persimmon and other fruits with more tannic acid, because tannic acid is easy to combine with iron, which will hinder the body's absorption of iron. Patients with nephritis, edema and poor renal function should not eat bananas, because bananas contain more sodium salts, which will aggravate edema and increase the burden on the heart and kidneys. All the fruits we eat have their own health care functions. When you are sick, if you eat fruit selectively, it will be of great help to your health. On the contrary, if you just choose blindly, it is not only useless, but also harmful to your health. It seems that eating fruit has a lot of knowledge, and we really need to learn more from snacks. The best time to eat fruit should be one hour before meals and two to three hours after meals. Most people have such a eating habit, that is, eating fruit after meals, whether it is the serving procedure at the banquet or the daily diet of most people.
