There is an English proverb that "the fruit in the morning is gold and silver from noon to 3 pm, copper from 3 pm to 6 pm, and lead after 6 pm". Eating fruit in the morning can help digestion and absorption, which is conducive to laxative. Moreover, the sweet and sour taste of fruit can make people refreshed and contribute to a good mood all day. On the contrary, eating fruits before going to bed is not conducive to digestion, especially fruits with high fiber content, which is even more harmful to health for people with poor gastrointestinal function. Eat less cool melons before going to bed.
Secondly, the best time to eat fruit is 65438+ 0 to 2 hours before meals, so as to absorb the essence of fruit. Because the gastrointestinal digestion of food is not carried out at the same time, but in stages according to the types of food, it takes our stomach about four hours to digest protein, at least six hours to digest fat, and only 1 hour to digest fruit. If fruit is eaten with other foods, our stomach will first decompose protein, then starch, then other foods such as fat, and finally fruit.

However, people usually think that eating fruit after meals is the best, but a professor from Taiwan Province Province put forward the latest opinion, emphasizing that eating fruit one hour before meals is the most beneficial. The reason is that fruit is raw. After eating cooked food raw, the body will not produce leukocytosis and other reactions, which is conducive to protecting the human immune system and thus enhancing the ability to prevent diseases and cancers. Eating fruit after meals has no such protective effect. In addition, after eating fruit, fructose contained in fruit can not enter the intestine in time to stay in the stomach for fermentation, resulting in organic acids, which will cause abdominal distension and diarrhea.
Fruit should be eaten before meals.
Many people have a big misunderstanding when eating fruit: treat fruit as a dessert, and the organic acids in it will combine with minerals in other foods, which will affect the digestion and absorption of the human body; Pectin in fruit can absorb water and increase the water content of food in the gastrointestinal tract, so eating fruit after meals will also increase the burden on the stomach.
Experts point out that the correct time to eat fruit is before meals 1 hour, and about 2 hours after meals (except persimmons). First of all, many ingredients in fruit are water-soluble, so eating before meals is beneficial to the absorption of essential nutrients. Secondly, fruit is a low-calorie food, and its average calorie is only 1/4 of that of pasta with the same weight, and that of pork with the same weight is about110. Eating low-calorie food first makes it easier to grasp the total calorie intake of a meal. 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.
In addition, we should also pay attention not to eat fruit before going to bed at night, otherwise the fullness of the stomach will affect sleep. Never think that eating fruit is a trivial matter. Only by eliminating these misunderstandings can we cultivate truly healthy living habits.
One hour before meals and one hour after meals.
People usually think that eating fruit after meals is the best, but a professor from Taiwan Province Province put forward a new viewpoint, emphasizing that eating fruit one hour before meals is the most beneficial. The reason is that fruit is raw. After eating cooked food raw, the body will not produce leukocytosis and other reactions, which is conducive to protecting the human immune system and thus enhancing the ability to prevent diseases and cancers. Eating fruit after meals has no such protective effect. In addition, if you eat fruit after a full meal, the fructose contained in it cannot enter the intestine in time, which will ferment in the stomach and produce organic acids, causing abdominal distension and diarrhea. Therefore, you need to wait for an hour after dinner before eating fruit.
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. 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.
