Watermelon is a good heatstroke prevention fruit in summer, but it also has taboos. Watermelon is a cold food, which is easy to hurt the spleen and stomach, so patients with spleen and stomach deficiency and loose stool should eat less. Because watermelon is cold, people with physical weakness, menorrhagia, chronic gastritis and indigestion should not eat more. Otherwise, eating too much is easy to hurt the spleen and stomach, causing bloating, diarrhea and loss of appetite; Watermelon has a high sugar content and is not suitable for diabetics. Normal people should not eat more watermelon, otherwise it will damage the spleen and stomach, causing indigestion or diarrhea; Patients with heart failure or nephritis should not eat more watermelons, so as not to increase the burden on the heart and kidneys and make the condition worse.
Tip: Watermelon should be cut and eaten. Don't store it for too long to avoid deterioration. It is best not to eat watermelon taken out of the refrigerator directly until the temperature of watermelon rises, otherwise it will damage the spleen and stomach because it is too cold.
Sweet watermelon is a fruit that people must eat every day in summer. However, not everyone can eat watermelon, even those who can eat it should pay attention to the scientific eating method. Some patients, or in some cases, it is best not to eat.
First, the sugar content of diabetic watermelon is about 5%, mainly glucose, sucrose and some fructose, which means that eating watermelon will increase blood sugar. Normal people can keep their blood sugar and urine sugar at a normal level because they can secrete insulin in time. People with diabetes are different. Eating too much watermelon in a short time will not only increase blood sugar, but also lead to acidosis and even life-threatening due to metabolic disorder. The daily intake of carbohydrates (carbohydrates) by diabetics needs to be strictly controlled. Therefore, if you eat watermelon many times a day, you should reduce the amount of meals and flour products (carbohydrates) accordingly, so as not to aggravate your illness.
Second, patients with renal insufficiency and renal insufficiency have greatly reduced the function of expelling water from the body, so edema of the lower limbs or the whole body often occurs. If this kind of patients eat too much watermelon, they will consume too much water and can't excrete excess water in time, which will lead to excessive water storage in the body and increased blood volume, which will not only aggravate edema, but also easily induce acute heart failure. Therefore, patients with renal insufficiency should eat less or not eat watermelon.
Third, in the early stage of cold, Chinese medicine believes that both wind-cold cold and wind-heat cold belong to exterior syndrome in the early stage, and divergent treatment methods should be adopted to treat them from the exterior. It is believed that the attack will aggravate the condition before the surface is solved. Watermelon has the function of clearing away heat. Eating watermelon at this time will aggravate the cold or prolong the course of disease.
Fourth, oral ulcer disease Oral ulcer is considered to be caused by yin deficiency and internal heat and virtual fire in traditional Chinese medicine. Because watermelon has diuretic effect. If people with oral ulcers eat more watermelons, the water needed for the recovery of oral ulcers will be discharged too much, which will aggravate the internal heat due to yin deficiency, lengthen the course of disease and make it difficult to heal.
Five, maternal physique is weak, Chinese medicine believes that eating more watermelon will be too cold and damage the spleen and stomach.
6. Don't eat before and after meals because a lot of water in watermelon will dilute the digestive juice in the stomach. Eating before and after meals will affect the digestion and absorption of food. Eating a lot of watermelon before meals will occupy the volume of the stomach and greatly reduce the intake of various nutrients, especially for children, pregnant women and wet nurses. For people who want to lose weight by dieting, eating watermelon before meals is a good way to reduce their food intake.
Seven, watermelon should not be eaten because watermelon is a "cold food." Anyone who eats too much will hurt the spleen and stomach, leading to poor appetite, indigestion, decreased gastrointestinal resistance and abdominal distension and diarrhea.
Eight, eat less ice west Although eating ice watermelon is very effective in relieving summer heat on a hot day, it is very irritating to the stomach and is easy to cause damage to the spleen and stomach, so we should pay attention to grasping the delicious temperature and quantity. Watermelon is best placed on the lowest floor of the refrigerator, where the temperature is about 8- 10℃, and the temperature is also the best. Don't eat more than 500 grams of watermelon at a time. Chew slowly. For people with dental caries (tooth decay) and tooth allergies, they will feel sour and painful after catching a cold, and people with poor gastrointestinal function are not suitable for eating iced watermelons.
It is bad to eat watermelon without spitting seeds.
Relevant data show that eating watermelon without spitting seeds may also cause abdominal distension, constipation, urinary retention, intestinal obstruction and so on. This should attract people's attention.
Watermelon seed shell is hard and difficult to digest. Eating a lot of watermelon seeds, watermelon seeds gradually gather together with intestinal peristalsis, leading to constipation, abdominal distension, and even intestinal obstruction and appendicitis.
According to the eating theory, watermelon seeds don't need to be eaten in the stomach, because they are tasteless and nutritious, black and hard, and can't be eaten at all.
Watermelon seed shell is hard and difficult to digest. Watermelon seeds are mixed with food and can be excreted with stool. A large number of watermelon seeds are eaten, and watermelon juice is absorbed by the human body. Watermelon seeds gradually gather together with intestinal peristalsis, leading to constipation, bloating, even intestinal obstruction, urinary retention, appendicitis and so on. Therefore, when eating watermelon, parents should tell their children to spit out the watermelon seeds, or dig out the seeds and give them to their children.

If the above situation occurs, don't worry, you can use 400-600 enema with warm soapy water, which can usually be cured at one time. If not, you can put your finger into your anus to dig out watermelon seeds or take them out with an anoscope in the hospital.
Watermelon is rich in nutrition. Chinese medicine believes that watermelon is cold and sweet, and has the effects of clearing away heat and relieving summer heat, quenching thirst and diuresis, and is the best fruit in summer.

People love to eat watermelon not only to appreciate its delicious taste, but also because it can cool and quench their thirst, relieve summer heat and make people feel comfortable. First of all, watermelon pulp is 94% water, as well as sugar, vitamins, various amino acids and a small amount of inorganic salts, which can most effectively supplement the water and nutrition needed by the human body in high temperature season; Secondly, the intake of water and inorganic salts can be metabolized into urine, and can also take away excess heat to achieve the effect of clearing away heat and relieving summer heat and benefiting qi.

He said that watermelon is sweet in taste, cold in nature and non-toxic, which not only "relieves annoyance and thirst, relieves summer heat", but also "soothes middle warmer, promotes diuresis, cures bloody dysentery, hangover and aphtha". Watermelon is also called "natural white tiger soup" in medical books. Baihu decoction is an effective prescription for treating excess heat such as high fever and polydipsia in traditional Chinese medicine. It is said that eating watermelon can achieve the effect of this prescription, which shows the doctor's attention. Today, symptoms such as fever, thirst, oliguria, hyperhidrosis and irritability caused by heatstroke or other acute fever in summer can be treated by eating watermelon.
In addition, the medicinal part of watermelon also has the skin called "watermelon Cui Yi" by TCM. In fact, the effect of clearing heat, diuresis and promoting fluid production of melon peel is far better than that of melon pulp, but few people know it. With a little repair, melon skin can become a rare summer delicacy in summer. The simplest way is to cut off the rough green husk and the residual melon pulp, cut them into strips and mix them with sesame oil, refined salt, sugar and vinegar; It can also be fried with sliced onions, ginger and other things, which will make people's appetite open after tasting.
It should also be stated that watermelon is good, but it is always a cold product. If people with weak body, cold stomach and weak stomach are gluttonous, it is easy to cause abdominal pain and diarrhea. Not suitable for eating with greasy things; If watermelon is eaten with warm food or drink, cold and heat are incompatible and it is easy to make people vomit. Watermelon should be eaten as soon as possible after being cut, otherwise its sweet and juicy pulp will easily become an ideal "culture medium" for bacteria; When eating watermelons stored in the refrigerator, be sure to leave them at room temperature for a while before eating, so as not to damage your body.
First, don't eat too much, otherwise it will hurt the spleen and stomach and cause pharyngitis.
Watermelon is a cold product, and eating too much is easy to hurt the spleen and stomach. Therefore, people with spleen and stomach deficiency and cold, dyspepsia and loose stool should eat less, while eating more will lead to abdominal distension, diarrhea, loss of appetite, accumulation of cold and dampness, leading to diseases. Eating too much watermelon at a time will dilute gastric juice, cause indigestion and decrease gastrointestinal resistance.
Second, don't eat watermelon at the beginning of a cold.
Don't eat watermelon at the beginning of a cold, otherwise it will aggravate the cold or prolong the cure time. Whether wind-cold cold or wind-heat cold, its initial stage belongs to exterior syndrome, so it should be treated from exterior to dispel evil. Watermelon is rich in nutrition. Chinese medicine believes that watermelon is cold and sweet, has the effects of clearing away heat and relieving summer heat, quenching thirst and diuresis, and is the best fruit in summer. But when eating watermelon, there are also some problems that need attention. First, don't eat too much, otherwise it will hurt the spleen and stomach and cause pharyngitis.

Eating too much watermelon at a time will dilute gastric juice, cause indigestion and decrease gastrointestinal resistance.
Third, don't eat watermelons that have been open for too long.
When the temperature is high, watermelon is easy to deteriorate after being opened for a long time, which will breed germs and lead to intestinal infectious diseases. Therefore, when eating watermelon, we should pay attention to choosing ripe fresh watermelon.
Fourth, people with renal insufficiency should not eat it.
Eating a lot of watermelon in a short period of time will increase the water in the body, which exceeds the physiological capacity of the human body. In patients with renal insufficiency, the ability of kidney to regulate water is greatly reduced, and too much water entering the body can not be regulated and excreted, resulting in a sharp increase in blood volume and easy death due to acute heart failure.
Fifth, people with oral ulcers should not eat.
Traditional Chinese medicine believes that the main causes of oral ulcers are internal heat due to yin deficiency, disturbance due to deficiency of fire, and burning flesh and blood veins. Watermelon has diuretic effect. If people with oral ulcer eat more watermelon, the water normally needed in the body will be discharged through the diuretic effect of watermelon, which will aggravate the state of insufficient vaginal fluid. Yin deficiency will increase internal heat and aggravate oral ulcer.
Sixth, diabetics should eat less.
The sugar content of watermelon is about 5%. If diabetics eat too much watermelon, it will also lead to high blood sugar, increased urine sugar and other consequences, and even severe ketoacidosis coma. If you eat 25-50 grams of watermelon at a time, it will have little effect on diabetics, so diabetics should pay attention to the right amount of watermelon. Methods to treat. Traditional Chinese medicine believes that exterior and interior are not attacked, otherwise exterior evil will enter the interior, and the condition will be aggravated. In the early stage of a cold, eating watermelon is equivalent to eating drugs that clear away heat from the interior surface, which will lead to the entry of pathogenic factors, aggravate the cold or prolong the cure time. However, when the cold gets worse and there are fever symptoms such as high fever, thirst, sore throat and yellow urine, you can eat some watermelons while taking normal drugs, which is helpful for the recovery of the cold.

Fruit pulp, fruit juice, seeds, skins, roots and leaves can all be used as medicine. Watermelon is known as "natural white tiger soup" because it is eaten raw to relieve summer heat. The folk proverb says, "Eat watermelon in summer, and you don't need to catch medicine". This shows that watermelon has a wide range of diseases, and eating watermelon in summer is very beneficial to human body. However, because watermelon is a sweet and cold product, people who usually suffer from chronic enteritis, gastritis and duodenal ulcer in traditional Chinese medicine should eat more. People with cold accumulation, cold pain or frequent urination should be careful to eat. Normal healthy people can't eat too much at a time, because too much water in the stomach will dilute the gastric juice and sometimes cause indigestion or diarrhea. Don't eat spoiled melons. People with renal insufficiency have poor balance adjustment ability and should not eat a lot of watermelons at one time. Excessive water will increase the burden on the heart and kidneys. Giving children watermelon can not only get rich nutrition, but also help stimulate appetite, help digestion, facilitate urination, promote metabolism, and dispel summer heat to keep fit. The effect on watermelon is recorded in Compendium of Materia Medica: "Eliminating vexation, quenching thirst, relieving summer heat, treating laryngitis, relaxing the middle energizer, promoting diuresis, treating blood dysentery and relieving blood poison."
