lychee
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.
watermelon
Watermelon is sweet and cool. 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.

In addition, watermelon is rich in sugar. If you eat more watermelons, you will consume a lot of sugar. Excess sugar will accumulate in the body and become fat, which will turn body fluids into acidic environment and affect human health. It will also affect the diet balance, reduce the intake of protein and minerals, thus causing nutritional imbalance. Therefore, watermelon should not be eaten more.
persimmon
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.
hawthorn
Hawthorn is sweet, sour and delicious, and has the special function of promoting digestion and resolving food accumulation.

banana
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.
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.
