Although different fruits have different nutritional values, it should be noted that some fruits should not be eaten more, otherwise it will be harmful. Let's find out which fruits can't be eaten more.

1, litchi

Litchi is a unique fruit in southern 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. If you eat too much litchi and 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 lead to 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.

2. Apple

Apple is sweet and sour, nutritious and convenient to eat, and can treat many diseases, so it is deeply 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. The ratio of potassium to sodium is too wide, and too much intake is not conducive to 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.

3.persimmons

Persimmon is a seasonal fresh fruit in autumn. Among fruits, persimmon ranks first in sweetness and is called "the sweetest fruit", while persimmon cakes made of persimmon are even 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. Tannin 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 it is easy to eat more for a long time, especially without peeling on an empty stomach.

4. Hawthorn

Hawthorn is sweet, sour and delicious, and 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. It was recorded in ancient medicine: "Hawthorn is out of breath and should not eat more." Eating too much consumes gas and hurts teeth. "Hawthorn is a product that breaks the qi and disperses the stagnation. It is not suitable for people who are usually weak in spleen and stomach or are taking tonics such as ginseng. 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. Therefore, hawthorn should not be eaten more.

5.bananas

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. Bananas contain more elements such as magnesium and potassium. Although these mineral elements are necessary for human health, if they are ingested too much at one time in a short period of 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.

Extended information 1. Five truths about fruit

1, you can't eat fruit during menstruation, which is easy to dysmenorrhea.

Eating fruits selectively helps to relieve "menstrual syndrome". It is best not to eat watermelon, pear and other cool fruits during menstruation. But "warm" fruits like apples, cherries, pomegranates and durians can be eaten, which can not only supplement water, but also vitamins and minerals, and help relieve symptoms such as loss of appetite during menstruation, backache and fatigue.

2, can not eat fruit on an empty stomach, will have a stomachache.

Eating fruit on an empty stomach varies from person to person. Generally speaking, people with hyperacidity and indigestion should not eat fruit on an empty stomach. If you have a strong digestive function and normal gastric acid secretion, it is not a big problem to eat fruit on an empty stomach and eat fruit in moderation. If you have poor digestive function, excessive gastric acid secretion, and even gastrointestinal diseases, then don't eat fruits on an empty stomach, especially fruits with heavy acidity such as hawthorn and lemon, which will make your already "sour" stomach even more uncomfortable.

3. Fruit is golden in the morning, silver in the afternoon and scrap iron at night.

The absorption of fruit nutrition has nothing to do with time. People's ability to digest and absorb fruits is mainly related to the secretion of digestive juice and gastrointestinal peristalsis, but not directly related to time. Whether in the morning or at night, as long as your gastrointestinal function is normal, there is no difference in the absorption of fruits.

4, can not eat fruit before meals, affecting digestion.

Eating fruit half an hour before meals can increase satiety, but it will not affect the digestion and absorption of food. Fruit is rich in sugar, which can be quickly converted into glucose in the body and absorbed by the body. With the increase of blood sugar, the brain's response to hypoglycemia can be quickly reduced. The crude fiber in fruit can give the stomach a "satiety", thus reducing appetite and reducing our demand for high fat and high protein in the diet.

5, you can't eat fruit after a meal, it will ferment and rot in your stomach.

It is most suitable to eat fruit after meals 1 hour. Eating fruits immediately after meals, slow-digested starch, protein and fat will affect fast-digested fruits, which may lead to flatulence and other symptoms. Eating fruit after meals 1 hour will not be like this.

Second, the principle of healthy eating fruit

Usually, people who have a good appetite and strong digestive ability, who eat too much and are afraid of heat, eat some fruit properly, which can slightly control the excess of the spleen and stomach and reduce the excessive internal heat. People who eat too much wine and meat, people who are hot, or patients with fever can eat some fruits appropriately. But the more you eat, the better. Eating too much cold will hurt the spleen and stomach. The ancients paid great attention to this. They don't eat fruit on an empty stomach, five-guarantee households don't eat fruit, and children and old people dare not give too much fruit to eat. Now there is no such concept. For patients with deficiency cold and a particularly greedy mouth, I can only make one step: if you really want to eat some fruit, soak it in a small amount of boiling water or cook it, which can cool it a little.

In fact, it is a western view to advocate eating more fruits. Westerners have a hot constitution. Their food is mainly all kinds of meat and dairy products, and there are few vegetables, so stomach heat and blood heat are their main symptoms. In the Qing Dynasty, we exported rhubarb for clearing stomach heat to Britain. Their idea is that eating more fruits can reduce obesity and make people healthier. We can't ignore our own physique and copy it completely. A girl and a graduate student in nutrition. Menstruation is a little abnormal, and my body is cold. After telling her some moxibustion methods, I reminded her to eat less fruit. She looked surprised: everyone said that fruit is beautiful, laxative, delicious and rich in vitamins. I explained, but she still looked unacceptable. She nodded politely and ignored him. I know that our views are contrary to what she usually studies and what professors and experts say. It's hard for her, too

Pay attention to region and seasonality when eating fruit. First of all, most fruits on the market are not local and seasonal. With the development of logistics, fruits have no geographical boundaries. And "one side of the soil and water support one side of the people", the fruit of a certain place corresponds to the local climate environment, but it is suitable for the local people. Eating fruit from other places is easy to hurt your health. For example, pitaya is produced in Hainan. Because of the hot weather in Hainan, eating pitaya is refreshing, but Hunan people will get cold when they come to eat pitaya.
