It is widely believed that fruits are rich in sugar, vitamins, and various nutrients, being both sweet and delicious, as well as beneficial for health and beauty. However, improper consumption of fruits can also lead to illness.
Lychees are extremely sweet and rich in glucose, fructose, and vitamins. However, excessive consumption of lychees for several consecutive days can lead to "lychee disease" in some people. In mild cases, symptoms include nausea, sweating, and limb weakness; in severe cases, dizziness, and even coma and convulsions, mostly occurring in the early morning. This is because lychees contain certain substances that lower blood sugar, which can reduce glucose levels in the blood, causing "acute hypoglycemia." Once this condition occurs, medical attention should be sought immediately. For mild cases, drinking oral glucose water can help, while for severe cases, intravenous glucose injection can rapidly alleviate the symptoms.
Pineapples have a fresh aroma and are rich in sugar, crude fiber, minerals, and vitamins. However, some people may experience allergic reactions after eating pineapple, such as nausea, vomiting, abdominal pain, diarrhea, numbness of the lips, and itchy skin. This is because pineapples contain glucosides and bromelain. Glucosides can irritate the oral mucosa, causing numbness of the lips, while bromelain can cause nausea and vomiting. People with allergies are more prone to this phenomenon. The preventive method is to cut the peeled pineapple into small pieces, soak them in light salt water for ten minutes, or heat them to destroy the bromelain before eating, which makes it safe.
persimmons are sweet, moist, and rich in sugar and vitamin C. However, persimmons are considered "cold" in nature and are not suitable for consumption by postpartum women and those with a weak constitution. Persimmons contain a significant amount of tannins, which are astringent. Eating too many can cause a dry mouth and numb tongue, reduce digestive secretions, and lead to constipation.
Persimmons also contain persimmon phenol and tannic acid. If a large amount is consumed on an empty stomach, it can solidify into hard masses under the action of gastric acid, causing "bezoar of the stomach." Symptoms of this condition include upper abdominal pain, bloating, acid reflux, vomiting, loss of appetite, and it can also lead to high intestinal obstruction. Therefore, although persimmons are delicious, they should not be eaten in excess. Only 1-2 should be consumed at a time. Do not eat persimmons on an empty stomach, do not eat the skin, and do not eat unripe persimmons.
Additionally, jujubes have thick flesh and a sweet taste, with effects of strengthening the spleen and stomach, moistening the lungs, and calming the mind. However, excessive consumption can produce phlegm and heat, and can damage teeth. Bananas are soft, fragrant, and sweet, with effects of moistening the intestines to relieve constipation, clearing heat, and detoxifying. However, they are "cold" in nature, so people with a weak spleen and stomach or those with diarrhea should consume them in moderation. Pears have soft flesh and abundant juice, with effects of moistening the lungs to relieve cough, clearing heat to resolve phlegm, and promoting bowel movements. However, due to their "cool" nature, excessive consumption can also harm the spleen and stomach, so people with diarrhea or postpartum blood deficiency should be cautious. Furthermore, peaches, when eaten in excess, can generate heat and easily lead to sores. Plums, when eaten in excess, can produce phlegm. Sour plums, when eaten in excess, can damage the teeth. Watermelon is a summer favorite, with effects of relieving summer heat, clearing heat, promoting urination, and quenching thirst. However, eating too much at once can also damage the spleen and stomach.
