Lychee is a special delicacy unique to southern China, with an exceptionally delicious and fresh taste. However, lychees should not be consumed in excess, as it may lead to lychee disease. This is because most of the monosaccharides in lychees are fructose. After being absorbed by the body, fructose must undergo a series of enzymatic catalysis to be converted into glucose for energy or into glycogen for storage, which is then oxidized and utilized by tissue cells. If too many lychees are consumed at once, an excessive intake of fructose can cause a significant drop in blood sugar (the concentration of glucose in the blood), leading to hypoglycemia. Therefore, lychee disease is an acute illness caused by low blood sugar, characterized by an onset in the early morning with initial symptoms such as sweating, cold limbs, fatigue, abdominal pain, and mild diarrhea, followed by sudden convulsions and coma.
If left untreated, it can lead to death within a few hours. This is especially true for children, who should be particularly careful not to eat too many, as it can seriously affect their health. Watermelon
Watermelon is sweet and cool in nature. For summer heat, thirst, and vexation in the chest and mind, one can eat some watermelon to relieve heat and clear heat. However, eating too much is not good for your health. From the perspective of Traditional Chinese Medicine, watermelon is cold-natured, and excessive consumption can easily cause adverse symptoms such as a cold stomach, abdominal fullness and bloating, and decreased digestive function. Additionally, watermelon is extremely rich in sugar. Eating too much watermelon leads to a large intake of sugar, and excess sugar is stored in the body as fat, making the body's fluids acidic, which affects health. It can also disrupt dietary balance, reducing the intake of protein, minerals, and other nutrients, leading to nutritional imbalances. Therefore, watermelon should not be eaten in excess. Persimmon
Persimmon is a seasonal fresh fruit of autumn. Among fruits, persimmon ranks first in sweetness, earning it the title of "the sweetest fruit," and persimmon cakes made from it are even sweeter. Persimmons are not only delicious but also nutritious. However, persimmons also have their drawbacks, and eating too many can be harmful. Persimmons contain a certain amount of tannic acid, with the skin having an even higher concentration. The astringent feeling in the mouth and numbness of the tongue when eating persimmons are due to the astringent effect of tannins. Tannins have a strong astringent effect and can easily combine with gastric acid in the stomach to form clots. Tannic acid also combines with proteins to form precipitates. Therefore, long-term and excessive consumption, especially on an empty stomach and without peeling, is not advisable. Hawthorn
Hawthorn is sweet and sour, and has a special effect of promoting digestion and resolving food stagnation. It is one of the best fruits for stimulating appetite and aiding digestion, but excessive consumption is harmful rather than beneficial. Eating too much hawthorn can damage the body's central qi, as hawthorn contains large amounts of vitamin C and fruit acids, among other components. From the perspective of food properties, hawthorn is sour and sweet. Ancient medical texts record: "Hawthorn breaks qi and should not be eaten in excess. Excessive consumption consumes qi and damages teeth." Hawthorn is a substance that breaks qi and resolves stagnation. People with a weak spleen and stomach, or those taking qi-tonifying herbs like ginseng, should avoid it. For children who are in the stage of replacing teeth, frequent and large consumption can be detrimental to dental growth and also affect appetite. Therefore, hawthorn should not be eaten in excess. Banana
Bananas are fragrant, soft, and delicious, so some people eat them in large quantities at once. However, this is very detrimental to health. Bananas contain relatively high amounts of elements like magnesium and potassium. Although these minerals are essential for human health, consuming them all at once in a short period can cause a sharp increase in the levels of magnesium and potassium in the blood, disrupting the balance of elements such as potassium, sodium, calcium, and magnesium in the body, which is harmful to health. Furthermore, eating too many bananas can significantly reduce gastric acid secretion, leading to gastrointestinal dysfunction and excessive mood swings. Therefore, bananas should not be consumed in excess. Apple
Apples are sweet, sour, and delicious, nutritious, convenient to eat, and can help treat various diseases, making them widely loved. However, excessive or binge eating of apples can also bring many disadvantages. This is because apples contain large amounts of sugars and potassium salts. For every 100 grams of apple, there are 100 milligrams of potassium but only 14 milligrams of sodium. The ratio of potassium to sodium is too extreme, and excessive intake is not good for the health of the heart and kidneys. It is especially burdensome for the heart and kidneys of patients suffering from coronary heart disease, myocardial infarction, nephritis, or diabetes, which is detrimental to their health. Therefore, apples should not be eaten in excessive amounts, and a daily intake of 1-2 apples is generally recommended.
