Edible taboo
Don't eat too much: Watermelon is the most natural natural drink, and it is rich in nutrition and has many benefits to the human body. However, although watermelon has many advantages, the side effects of large or long-term consumption can not be ignored. Wang Mingying said in "Edible Materia Medica": Watermelon is cold and antipyretic, and it has the name of natural white tiger soup, but it is not suitable to eat more. Li Shizhen's Compendium of Materia Medica said: Watermelon and melon are both cold, which is thought by the common people to be a quick way to remove dew, but I don't know the harm of damaging the spleen and helping dampness. Yuan Pengfei's "Life Extension Book" said: northerners are generous, but they are still used to eating, while southerners are thin, and eating too much is easy to cause cholera. There is another cloud: Chen Fengyuan is a satrap in Zhou Fang. He eats too many melons in summer, and suddenly his back aches and his legs ache in autumn, so he can't move. He just eats melons. Therefore, TCM syndrome differentiation belongs to spleen and stomach deficiency cold, cold accumulation abdominal pain, frequent urination and more urine; And people who usually have chronic enteritis, gastritis, duodenal ulcer, etc. It belongs to deficiency-cold constitution and should not be eaten more. Normal and healthy people should not eat too much at one time or for a long time, because watermelon contains a lot of water, which will dilute the gastric juice in the stomach and cause indigestion or diarrhea.
Cann't eat after deterioration: Watermelon can't eat after deterioration, which is easy to cause gastrointestinal diseases and diarrhea. Wei Qing and Zhang Lu said in Ben Feng Jing Yuan that watermelon is sweet in taste and cold in nature, which can stop diarrhea. Its nature is benevolence and warmth, and clearing phlegm and promoting fluid production is its nature. He also quoted the cloud in Xiang Gan Zhi: After eating watermelon, I ate my son, that is, I didn't smell the melon, so I can see the merits of warming and dispersing. Those who eat too many fruits and vegetables and have abdominal pain caused by cold accumulation in the gastrointestinal tract can take Lizhong decoction for treatment. Although watermelon is good for people, please remember the folk proverb in Taiwan Province Province: Eat watermelon every day and get sick in the middle of the night.
Diabetic: Watermelon contains about 5% sugar, mainly glucose, sucrose and some fructose, which means eating watermelon will raise 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.
Renal insufficiency: In patients with renal insufficiency, the function of draining water from the body is greatly reduced, so edema of lower limbs or 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.
Early stage of cold: Chinese medicine believes that both wind-cold cold and wind-heat cold belong to exterior syndrome in the early stage, so divergent treatment should be taken 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.
Patients with oral ulcer: Chinese medicine believes that oral ulcer is caused by internal heat due to yin deficiency and disturbance of deficiency fire. 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.
Puerpera: Puerpera's physique is weak. Chinese medicine believes that eating more watermelon will be too cold and damage the spleen and stomach.
Not suitable for eating before and after meals: because a large amount 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 watermelon in large quantities before meals will occupy the volume of the stomach and greatly reduce the intake of various nutrients, especially for children, pregnant women and lactating mothers. For people who want to lose weight by dieting, eating watermelon before meals is a good way to reduce their food intake.
Don't eat too much: 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.
Eat less ice watermelons: Although eating ice watermelons on a hot day has a good effect of relieving summer heat, it is very irritating to the stomach and is easy to harm 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.
Watermelon is too long to eat: after the weather is high, it is suitable for bacterial reproduction. If you eat watermelon that has been opened for too long and has been contaminated by bacteria, it will lead to gastrointestinal infectious diseases. Therefore, when eating watermelon, we should pay attention to choosing ripe fresh watermelon.
