Be aware that fruits can also have side effects
As is well known, fruits have high nutritional value, and some even have certain health benefits, making them a beloved food. However, like other foods, fruits also have worrying side effects. If consumed carelessly, it can harm one's health in minor cases and even be life-threatening in severe ones.
(I) Lychee
Lychees are extremely sweet and rich in glucose, fructose, and vitamins. However, consuming too many lychees for consecutive days can lead to "lychee disease." In mild cases, this causes nausea, sweating, and limb weakness; in severe cases, it can lead to dizziness, and even coma and convulsions, often occurring in the early morning. This is because lychees contain certain substances that lower blood sugar, which reduces glucose levels in the blood, causing "acute hypoglycemia." Once this happens, medical attention should be sought immediately. For mild cases, drinking oral glucose water can help, while severe cases may require intravenous glucose injection to quickly alleviate the symptoms.
(II) Pineapple
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 skin itching. This is because pineapples contain bromelain and glycosides. Glycosides 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. 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.
(III) Persimmon
Persimmons are sweet, moist, and rich in sugars and vitamin C. However, persimmons are considered "cold" in nature and are not suitable for consumption by postpartum women or those with a weak constitution. Persimmons contain a high amount of tannins, which are astringent. Eating too many can cause a dry mouth and tongue numbness and reduce digestive secretions, leading 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 stomach acid, causing "bezoars." Symptoms of this condition include upper abdominal pain, bloating, acid reflux, vomiting, loss of appetite, and it can lead to complications like high intestinal obstruction. Therefore, although persimmons are delicious, they should not be eaten in excess. Limit to 1-2 at a time, and do not eat them on an empty stomach, with the skin on, or when unripe.
(IV) Cherry
Although cherries are beautiful and delicious, due to their extremely high iron content and the presence of certain cyanogenic glycosides, excessive consumption can lead to iron poisoning and even cyanide poisoning.
(V) Mulberry
Ripe mulberries are sweet and juicy but contain substances like hemolytic agents, allergens, and hyaluronic acid. Eating too many can easily lead to hemorrhagic enteritis, and in severe cases, it can be fatal.
(VI) Plum and Ginkgo
Fruits such as plums, ginkgo nuts, and apricots all contain trace amounts of hydrogen cyanide. As the saying goes, "Peaches nourish life, apricots harm life, and under the plum tree, the dead are buried," which actually refers to hydrogen cyanide poisoning caused by eating too many apricots, plums, and similar fruits.
(VII) Pear
Eating too many pears can damage the spleen and stomach, promote dampness, and disrupt gastrointestinal function, leading to diarrhea and other illnesses. Therefore, those who are sensitive to cold, have a weak spleen, or suffer from diarrhea should avoid them. Additionally, they should not be consumed in large amounts after an injury, postpartum, or when a child has recovered from chickenpox.
(VIII) Banana
Bananas are popular with everyone, but eating a large amount on an empty stomach is not advisable. Due to their high magnesium content, it can alter the ratio of magnesium to calcium in body fluids, causing a sharp increase in blood magnesium. This has an inhibitory effect on the cardiovascular system, leading to significant numbness, such as muscle paralysis, drowsiness, and fatigue. Furthermore, because of their "cold" nature, people with a weak spleen and stomach, or those who suffer from stomach pain and diarrhea, should eat them sparingly, and those with excess stomach acid should avoid them. People with poor kidney function, as well as those with arthritis or muscle pain, should preferably not eat bananas. This is because bananas are excessively high in potassium, which has serious side effects on kidney diseases. Additionally, bananas can slow down local blood circulation, causing metabolic waste to build up and increasing the consumption of vitamin B in the body, thereby worsening joint and muscle pain.
