Introduction: Summer is a season rich in fruits, so many people like to eat fruits for health, but we can't eat more fruits in summer, otherwise it will be harmful to our health. So how should we eat fruit healthily in summer? Let me give you an answer and take stock of some taboos about eating fruit in summer. Just go and see.

Although six kinds of fruits are nutritious and healthy in summer, they should not be greedy.

Eating more fruits is very beneficial to physical and mental health, especially in summer, many women like to eat different kinds of fruits, which can not only cool off the heat, but also help digestion and even lose weight. However, not all fruits are suitable for mass consumption. The following six fruits must be eaten less in summer.

First, persimmons

Features: Persimmon is the sweetest fruit among fruits, which is called "the sweetest fruit", while persimmon cakes made of persimmons are sweeter. Persimmons are not only delicious, but also nutritious. But persimmons also have shortcomings, and eating too much is also harmful. Persimmon contains a certain amount of tannin (tannic acid), and the content of persimmon peel is high. When eating persimmon, the astringency and numbness of the tongue are the reasons for the convergence of tannins.

Note: Tannic acid has a strong astringent effect, and it is easy to combine with gastric acid in the stomach, thus solidifying into blocks. Tannic acid combined with protein is easy to precipitate, so eating too much for a long time, especially on an empty stomach, will be harmful to your health.

Second, hawthorn

Features: Hawthorn is sweet and sour, which has the special function of promoting digestion and resolving food accumulation. It is one of the best fruits to stimulate appetite and help digestion, but eating too much is harmful. Eating too much hawthorn will hurt people, because hawthorn contains a lot of vitamin C and fruit acid. Judging from the medicinal properties of food, hawthorn tastes sweet and sour.

Precautions: It was recorded in ancient medicine: "Hawthorn is dead, so it is not advisable to eat more. Eating too much consumes gas and hurts teeth. " Hawthorn is a product that breaks qi and accumulates stagnation. People with weak spleen and stomach or taking tonics such as ginseng are not suitable for eating. The child is in the period of changing teeth. If you eat a lot often, it will be bad for the growth of teeth and affect your appetite.

Third, bananas.

Features: Banana is a delicious fruit, so some people eat many bananas at a time. As we all know, this is very bad for your health.

Be careful: bananas contain many elements such as magnesium and potassium. These mineral elements are necessary for human health, but if they are ingested too much at one time in a short time, the contents of magnesium and potassium in the blood will increase sharply, resulting in the imbalance of potassium, sodium, calcium, magnesium and other elements in the body, which is harmful to health. In addition, eating more bananas will also cause gastrointestinal dysfunction and excessive mood swings due to the greatly reduced gastric acid secretion. Therefore, bananas should not be eaten in excess.

Fourth, Apple.

Features: Apple is sweet and sour, nutritious, convenient to eat, and can treat many diseases, so it is widely loved by people. But if you eat too much or eat too many apples, it may also bring many disadvantages. This is because apples contain a lot of sugar and potassium salts, of which 100 grams of apples contain 100 mg of potassium and only 14 mg of sodium, and the ratio of potassium to sodium is too wide.

Note: Eating too many apples is bad for the health of the heart and kidneys. Especially for patients with coronary heart disease, myocardial infarction, nephritis and diabetes, it increases the burden on the heart and kidneys and is not conducive to health. Therefore, apples should not be eaten too much, and the general consumption is 1-2 apples per day.

Five, litchi

Features: Litchi is a unique fruit in the south of China. It is very delicious. But litchi should not be eaten more, otherwise litchi disease may occur. Because most of the monosaccharides contained in litchi are fructose, fructose can be converted into energy-supplying glucose or stored glycogen after being absorbed by human body and catalyzed by a series of enzymes, which is oxidized by tissues and cells.

Note: If you eat too much lychee and intake too much fructose at a time, your blood sugar (blood sugar refers to the concentration of glucose in your blood) will be much lower than normal, which will cause hypoglycemia. Therefore, litchi disease is an acute disease caused by hypoglycemia, which is characterized by early onset in the morning, often with early symptoms such as sweating, cold limbs, fatigue, abdominal pain, diarrhea, and then sudden convulsions and coma. If left untreated, he will die within a few hours. Children, in particular, should be careful not to eat more, otherwise it will seriously affect their health.

Six, peaches

Characteristics: Peach is characterized by high iron content and contains protein, sugar, calcium and pectin. Especially suitable for people with anemia. Pectin contained in peaches can promote intestinal peristalsis, so it can prevent constipation. Although peaches are delicious, you can't eat too much. Eating too much can cause acute gastrointestinal diseases such as diarrhea. Watermelon Watermelon is sweet and cold. If you are thirsty and have a hot heart, you can eat some watermelons appropriately to relieve the summer heat. But eating too much is bad for your health.

Caution: According to the theory of traditional Chinese medicine, watermelon is cold, and excessive consumption can easily cause stomach cold, abdominal distension, gastrointestinal digestive function decline and other adverse symptoms. In addition, watermelon is rich in sugar. If you eat too much watermelon, you will consume a lot of sugar, and the excess sugar will accumulate in the body and turn into fat, which will turn body fluids into an acidic environment and affect human health. But also affect the diet balance, reduce the intake of protein and minerals, resulting in nutritional imbalance.

Eight misunderstandings of eating fruit in summer

The temperature is gradually warming up, and the delicious "fruit season" is coming again. In an interview with the reporter of Life Times, experts pointed out that eating fruits should follow the principle of "freshness, seasonality, variety and moderation". If you want to give full play to the health benefits of fruits, you must avoid the following eight misunderstandings.

Eat if you want.

Fruits contain more organic acids and tannins, and some also contain protease with strong activity. Eating at the wrong time may cause irritation and harm to the stomach. Fu Jinru, chairman of Tianjin Nutrition Society, said: "Bananas, for example, have high magnesium content. Eating too much on an empty stomach will lead to the imbalance of magnesium and calcium in the blood, which may have an inhibitory effect on the cardiovascular system. Generally speaking, most fruits are suitable for eating before meals 1-2 hours. "

There's no harm in eating more.

Donglian Cai, chief physician of the Nutrition Department of Changhai Hospital affiliated to the Second Military Medical University, pointed out that it is appropriate to eat about 200 grams of fruit every day. The dietary fiber content of most fruits is very high, and if you eat too much, you will have stomach pain and abdominal distension.

In addition, elderly people with stomach deficiency and cold should not eat more oranges; People with poor gastrointestinal tract or constipation should eat less persimmons. Some people eat pineapple, which can induce allergies. People with gastrointestinal diseases and coagulation disorders should not eat it. People with high sugar content, high potassium content, high blood sugar and renal insufficiency should eat less bananas.

Fruit can replace vegetables.

Although the nutrition of fruits and vegetables is similar, fruits cannot replace vegetables. For example, the vitamin C content of Chinese cabbage and spinach is about 10 times higher than that of apples, peaches and pears. But if you want to meet the recommended amount of vitamin C for one day, you should eat 5 kilograms of Fuji apples.

Fruit has the highest vitamin content.

Vitamins are a big family with many members. Fruits may be rich in these ingredients, but they also have disadvantages. For example, fruits do not contain fat-soluble vitamins, and most fruits have limited vitamin C content.

Fruit for a meal, beauty beauty.

Donglian Cai introduced that the contents of protein, fat, calcium and iron in fruits are less. Eating fruits for a long time will definitely lead to insufficient intake of protein and lipids, resulting in malnutrition and anemia.

Eating more fruits can help you lose weight.

Although the calorie per unit weight of fruit is lower than that of rice, it is easy to eat more because it tastes good. If you are not careful, your sugar intake will exceed the standard. This will not only fail to lose weight, but even have the opposite effect.

Peel off the skin to prevent pesticides.

Fruit skin and its subcutaneous parts are often the most nutritious parts, so it is a pity to throw them away. In fact, you don't have to worry too much about pesticide residues on the peel. China has banned the use of highly toxic pesticides in directly imported foods such as fruits and vegetables, and most fruits are not eaten until a few days or even months after harvest, and pesticides have basically decomposed.

Donglian Cai suggested that fruits can be washed repeatedly before eating, or soaked in rice washing water for a period of time to remove the residual substances on the surface.

Foreign fruits are more nutritious.

"Foreign fruits" have high transportation, packaging and storage costs and high prices. In order to look good, the surface of this fruit may be treated with preservatives or waxing to keep the appearance bright, but the nutrients will be gradually lost during transportation. So it's best to eat local seasonal fruits.

Eating fruit in summer is divided into "cold" and "hot"

Although many fruits have just come into the market in early summer, many people have already had problems eating them. When apricots are eaten too much and get angry, symptoms such as dizziness, stomachache and nosebleeds will appear to see a doctor. Although summer is the peak season for eating fruits, and fruits are rich in vitamins, water and minerals, which are very beneficial to human health. However, from the perspective of traditional Chinese medicine nutrition, fruits are divided into cold and hot. If your body is not suitable for eating cold or hot fruit, eating it inappropriately or eating too much will have a serious negative impact on your body.

Then, how can fruits be divided into cold and hot, and how should people choose?

Cool fruit relieves dryness and heat

According to Dr. Li, summer fruits are mostly cold, such as pears, apples and various melons. Generally speaking, people with excessive heat constitution have strong metabolism in summer, sympathetic nerves are dominant, sweat a lot, often have red face, dry mouth, irritability and constipation, and especially like to eat cold things in summer. Therefore, people with hot constitution can eat more cold fruits appropriately.

However, you should not eat more cold fruits, otherwise it will be harmful to your health. Apples, for example, are sweet and have the functions of stopping diarrhea, relaxing bowels and helping digestion. Eating regularly can make the skin white and tender. However, because it is rich in sugar and potassium salt, eating too much will be harmful to the health of the heart and kidneys. Patients with coronary heart disease, myocardial infarction, nephritis and diabetes can't eat more, and those with insufficient middle qi and mental fatigue can eat more as nourishing fruit.

Pears, oranges, grapefruit and other fruits have the functions of relieving cough and resolving phlegm, moistening the lungs and helping digestion, but eating too much can easily cause gastrointestinal discomfort, toothache, hemorrhoids and even skin rash. Therefore, people with stomach trouble and cold stomach had better eat less.

Dr. Li particularly emphasized that people with qi deficiency and spleen deficiency should be especially cautious when choosing cold fruits such as watermelon, cantaloupe, mango, pear and banana, and it is best not to eat them. Qi deficiency generally refers to people or children with insufficient qi and weak strength. Such people are generally pale, thin and unable to eat; Spleen deficiency means poor digestive system and slow intestinal peristalsis. Therefore, the more you eat cool fruit, the more you will reduce gastrointestinal peristalsis and make your muscles weak. Eating too much will lead to bloating due to indigestion. Therefore, the elderly and children with poor gastrointestinal function are not suitable for eating cold fruits. If they really want to eat, they can eat less after lunch and before dinner, but not too much.

Cold fruits in summer: cantaloupe, watermelon, pear, banana, kiwi, mango, persimmon, water chestnut, wax gourd, grapefruit, etc.

Suitable crowd: excess heat constitution.

Warm fruits tonify deficiency and cold.

Although there are many cool fruits in summer, among many fruits, such as litchi, longan and apricot, which are warm, they are still popular. Especially people with deficiency-cold constitution have deficiency of qi and spleen, low basal metabolic rate, less heat generated in the body, and their limbs are cold even in summer. Comparatively speaking, these people are whiter than ordinary people, and they are seldom thirsty, and they don't like touching cold things, including entering air-conditioned rooms. Therefore, it is undoubtedly a good cold tonic for these people to eat more warm fruits.

However, for most people, eating too much warm fruit in hot weather is easy to get angry. For example, litchi contains hypoglycemic ingredients, and if you eat too much, you will have a low sugar reaction. For people with hot constitution, they can't eat warm fruits because they are full of energy, difficult to fall asleep at night and have high metabolic rate. In addition, children with fever or inflammation of an organ should try to avoid eating it.

Warm fruits in summer: litchi, peach, longan, guava, cherry, coconut, durian, apricot, etc.

Suitable crowd: deficiency and cold constitution.

Some fruits are not suitable for freezing.

The fruit between cold and heat belongs to peace. This kind of fruit, such as grapes, pineapples, mangoes, olives, gingko and plums, can be eaten by people with different constitutions. However, there are many things to pay attention to when eating fruit. Be careful when eating, especially in summer. Don't be greedy for cold. Not all fruits are suitable for frozen consumption.

Dr. Li suggested that fruits must be fresh and nutritious. Eat more whole fruits, try to eat less canned fruits and don't drink fruit juice, because you will lose a lot of dietary fiber. In addition, eat more fruits with colorful flesh, such as hawthorn, jujube, kiwi fruit and mango, which are rich in vitamins C and B, and are very nutritious.

Besides paying attention to nutrition, the most important thing to eat fruit in summer is not to be greedy. Many people like to eat frozen fruits in the refrigerator, although the chilled fruits are particularly delicious and comfortable to eat. However, fruits that are too cold will stimulate gastrointestinal peristalsis to slow down, which will cause indigestion, especially for people with cold stomach or mild gastritis.

Dr. Li said that litchi, persimmon and pear are usually frozen for an hour or two, so don't leave them until the next day; But some fruits are not necessarily delicious after freezing, such as watermelon, cantaloupe, peach and apricot. After freezing for an hour or two, they often feel that there is no sweetness. In fact, this is not because of nutrient loss, but because the water in the refrigerator has been absorbed into the fruit for too long, and the sweetness has been diluted. So fresh fruit like this is the best, if it is to be frozen for about half an hour. In addition, it is best not to eat frozen bananas. First of all, they are not sweet. Second, banana skin and even banana meat will turn black after freezing, which is the result of sugar fermentation. It is best not to eat them.

Conclusion: Although these fruits are rich in nutrition, they are not suitable for eating more in summer. For the sake of health, everyone should fast.
