What foods should not be eaten in summer?

These fruits should not be eaten in summer. Litchi is a unique fruit in southern China. It tastes very delicious. But litchi should not be eaten more, otherwise litchi disease may occur. Because most of the monosaccharides contained in litchi are fructose, fructose can be converted into energy-supplying glucose or stored glycogen after being absorbed by human body and catalyzed by a series of enzymes, which is oxidized by tissues and cells. If you eat too much litchi and too much fructose at a time, your blood sugar (blood sugar refers to the concentration of glucose in your blood) will be much lower than normal, which will lead to hypoglycemia. Therefore, litchi disease is an acute disease caused by hypoglycemia, which is characterized by early onset in the morning, often with early symptoms such as sweating, cold limbs, fatigue, abdominal pain, diarrhea, and then sudden convulsions and coma. If left untreated, he will die within a few hours. Children, in particular, should be careful not to eat more, otherwise it will seriously affect their health. Watermelon Watermelon is sweet and cold. If you are thirsty and have a hot heart, you can eat some watermelons appropriately to relieve the summer heat. But eating too much is bad for your health. This is because, according to the theory of traditional Chinese medicine, watermelon is cold, and eating too much can easily cause stomach cold, abdominal distension, decreased gastrointestinal digestion and other adverse symptoms. In addition, watermelon is rich in sugar. If you eat too much watermelon, you will consume a lot of sugar, and the excess sugar will accumulate in the body and turn into fat, which will turn body fluids into an acidic environment and affect human health. But also affect the diet balance, reduce the intake of protein and minerals, resulting in nutritional imbalance. Therefore, watermelon should not be eaten more. Persimmon Persimmon is a seasonal fresh fruit in autumn. Among fruits, persimmon ranks first in sweetness and is called "the sweetest fruit", while persimmon cakes made of persimmon are even sweeter. Persimmons are not only delicious, but also nutritious. But persimmons also have shortcomings, and eating too much is also harmful. Persimmon contains a certain amount of tannin (tannic acid), and the content of persimmon peel is high. When eating persimmon, the astringency and numbness of the tongue are the reasons for the convergence of tannins. Tannin has a strong astringent effect, and it is easy to combine with gastric acid in the stomach, thus solidifying into blocks. Tannic acid combined with protein is easy to precipitate, so it is easy to eat more for a long time, especially without peeling on an empty stomach. Hawthorn Hawthorn tastes sweet and sour, and has the special function of promoting digestion and resolving food accumulation. It is one of the best fruits to stimulate appetite and help digestion, but eating too much is harmful. Eating too much hawthorn will hurt people, because hawthorn contains a lot of vitamin C and fruit acid. Judging from the medicinal properties of food, hawthorn tastes sweet and sour. It was recorded in ancient medicine: "Hawthorn is out of breath and should not eat more." Eating too much consumes gas and hurts teeth. "Hawthorn is a product that breaks the qi and disperses the stagnation. It is not suitable for people who are usually weak in spleen and stomach or are taking tonics such as ginseng. The child is in the period of changing teeth. If you eat a lot often, it will be bad for the growth of teeth and affect your appetite. Therefore, hawthorn should not be eaten more. Banana Banana is a delicious fruit, so some people eat many bananas at once. As we all know, this is very bad for your health. Bananas contain more elements such as magnesium and potassium. Although these mineral elements are necessary for human health, if they are ingested too much at one time in a short period of time, the contents of magnesium and potassium in the blood will increase sharply, resulting in the imbalance of potassium, sodium, calcium, magnesium and other elements in the body, which is harmful to health. In addition, eating more bananas will also cause gastrointestinal dysfunction and excessive mood swings due to the greatly reduced gastric acid secretion. Therefore, bananas should not be eaten in excess. Apple is sweet and sour, nutritious and convenient to eat, and can treat many diseases, so it is widely loved by people. But if you eat too much or eat too many apples, it may also bring many disadvantages. This is because apples contain a lot of sugar and potassium salts, of which 100 grams of apples contain 100 mg of potassium and only 14 mg of sodium. The ratio of potassium to sodium is too wide, and too much intake is not conducive to the health of the heart and kidneys. Especially for patients with coronary heart disease, myocardial infarction, nephritis and diabetes, it increases the burden on the heart and kidneys and is not conducive to health. Therefore, apples should not be eaten more. Generally, eating too many peaches is easy to get angry every summer. It is not advisable to eat more sweets in summer. Be careful of getting angry and getting wet phlegm. The weather is getting hotter and hotter. Under the attack of heat and humidity, many people lost their appetite for food. Sweet cakes, cool ice cream drinks and sweet fruits have become many people's favorites. However, experts warn that eating too many sweets in summer can not only relieve the heat, but will aggravate the symptoms of getting angry. Professor Chen, the chief nutritionist of the Nutrition Department of Shanghai Huadong Hospital, told the reporter of Life Times that the summer climate is humid and sultry, and people are prone to get wet, and eating sweets will make them more wet and phlegm, making people feel that there is more "a fire" in the body. Xiang En, a professor of Chinese medicine at China-Japan Friendship Hospital, also said that there are many sweet fruits in summer, such as lychee and cantaloupe, which actually make people get angry easily. If you eat too much, you will have symptoms such as sore throat and nosebleeds. It is not only the theory of traditional Chinese medicine that eating too sweet will get angry, but also western nutrition supports this view. Chen told reporters that eating too much sweets will consume a lot of B vitamins in the body, and there will be symptoms such as glossitis, angular stomatitis and eye pain. In addition, the summer air pressure is low and sultry, and sweets contain a lot of carbohydrates, which will produce a lot of carbon dioxide after metabolism in the human body, which will increase the burden on the lungs. So eating too many sweets will make people feel more bored. Finally, sweets will affect appetite, aggravate thirst, make people feel bloating and don't want to eat. This will prevent people from eating other nutritious foods and aggravate the symptoms of "getting angry". Therefore, you can't eat too many sweets in summer. Drink less sweet drinks and more tea and water. If your breath is heavy, you'd better drink honeysuckle tea, chrysanthemum tea or cassia seed tea. The traditional summer drink mung bean soup can not only supplement the minerals lost with sweat, but also help the human body absorb the B vitamins consumed by eating sweets, which is also very recommended. Too sweet fruits, such as litchi and cantaloupe, should be avoided, but watermelon can be eaten properly. In addition, don't eat too many cold and greasy things, and drink a small amount of water many times. Eat hot pot once a week at most in summer. There are many kinds of hot pots in summer, but most of them are "cool" and "fire-removing". Zhangqian, nutritionist, deputy director of the Nutrition Department of Beijing Tongren Hospital, said that adding a small amount of cool herbs to improve the hot pot had very limited effect. No matter what kind of hot pot it is, it is better to eat less in summer and eat it once a week at most. The culprit of several problems that must be paid attention to in summer supper barbecue: crayfish eating crayfish with diarrhea and high fever in the sea is the most spectacular supper scene. A large number of people are eating shrimp, and every table is filled with big pots of shrimp. People wear disposable gloves, and when they are in a hurry, they lose them and eat them directly with their hands. This unrestrained and hearty feeling not only fills their appetite, but also releases their emotions. However, after many people are addicted, they often have stomachache in the middle of the night and have symptoms such as diarrhea and high fever, so they have to run to the hospital. Zhou Xiao is one of them. Recently, he is addicted to crayfish. After eating for two days, my stomach hurts a little. At first, he didn't care. Later, he ate crayfish, and at night he had diarrhea, high fever and other symptoms. He realized that it might be the ghost of spicy crayfish. Tang Hansheng, director of emergency department in central hospital of wuhan, is a very careful doctor. Since the summer, he found that more and more patients came to see the emergency department because of diarrhea, high fever, suppurative tonsils and inflammation. After his patient's inquiry and investigation, it was found that most of these patients had the same experience of eating crayfish. After eating crayfish, many patients eat cold drinks and cold beer, which makes the disease hidden danger even greater. Generally speaking, lobsters that die for more than two or three hours will deteriorate, and customers will easily lead to symptoms of food poisoning such as diarrhea and abdominal pain after eating them. Shi, director of the Department of Gastroenterology, Wuhan First Hospital, said that most lobsters are farmed artificially and the growing environment is relatively clean. But lobsters with more parasites on their heads are generally not suitable for eating. Fresh lobsters can still be safely eaten after cleaning and high-temperature cooking. In addition, the hot and humid environment in summer provides suitable conditions for the growth and reproduction of intestinal pathogens. Crayfish is a cold food. Eating too much is easy to hurt the spleen and stomach, and protein eating too much is also easy to cause indigestion. It is recommended not to exceed half a kilogram at a time. Tip: Don't eat dead lobster. When selecting lobsters, we should pay attention to the fresh crayfish with bright and full color, compact meat, certain elasticity and chewiness. If it is a crayfish that has been left for a while or has died, the meat is tender and looks empty and not full. The green shell is better than the red shell. When people buy lobster in the market, they should look at the color. Lobsters generally have two kinds of shells: red and green. Generally, the green shell is better than the red shell, because the lobster shell with green shell is thin and fleshy. Moreover, green-shelled lobsters generally live in deep freshwater lakes, which are relatively clean and easy to taste after being cooked. They are not only full, but also tender. The lobster we eat today must be cooked thoroughly. Most of them are mainly farmed and relatively clean. However, it is better to be careful. If eaten raw or half cooked, people may be infected with parasites, so crayfish must be cooked, because high temperature can completely kill parasites. If people process crayfish by roasting, frying, salting and drunkenness, they may be infected with paragonimiasis after eating, because this processing method cannot kill all the paragonimiasis cysts in crayfish. Don't forget, lobster with its head and intestines removed belongs to rotten food, and there are many parasites on its neck and head. Some people will have allergic reaction symptoms and rash all over after eating lobster. This is because the body has a heterogeneous protein reaction, which can seriously lead to paragonimiasis. Eating unclean or undercooked lobster is easy to get acute gastroenteritis. The second culprit: 49-year-old Mr. Chen injured his gastric mucosa by drinking cold beer. After intravenous drip of cephalosporin twice in the nearest clinic due to cough, I went to midnight snack and drank two bottles of beer at night, and I felt headache, palpitation and shortness of breath. His family sent him to Wuhan First Hospital. Doctors say many people don't know that anti-inflammatory drugs and alcohol can cause serious adverse reactions. 22-year-old Xiao Wang went out for a snack with friends after swimming. Because of the hot weather, three young people drank 13 cold beer and felt very comfortable at that time. Xiao Wang started to have loose bowels when he came home at night, and went to the toilet five times a night. The hospital diagnosed him with acute enteritis. Recently, the number of patients with diarrhea and acute gastritis in the intestinal outpatient department and emergency department of this hospital has increased, and the patients are mainly young and middle-aged. Most of them have many experiences of drinking cold beer and eating barbecue. The reporter learned from many hospitals in this city that the number of patients with gastrointestinal diseases, acute pancreatitis and gout recurrence in various hospitals has increased rapidly since admission. A considerable number of male patients are induced by drinking too much beer, especially cold beer, which is called beer patients. Shi pointed out that cold beer is not suitable for everyone, especially patients with gout, chronic gastroenteritis, heart disease, hypertension and liver disease. Wu Liming, deputy chief physician of the Department of Internal Medicine of the First Hospital of the City, said that Mr. Chen's reaction was due to the sulfur-like reaction after drinking cephalosporin. Wu Liming said that in addition to cephalosporins, similar drugs include metronidazole, tinidazole and furazolidone. For patients who need to use antibiotics because of their illness, especially middle-aged and elderly people with cardiovascular diseases, it is best not to drink alcohol during the use of the above antibiotics and within 7 days after stopping taking them. Tips: Drinking heavily for a short time can lead to acute diseases. Drinking a lot of beer for a short time is enjoyable, but this practice is likely to lead to gastrointestinal discomfort. Although moderate intake of beer can promote gastrointestinal peristalsis, excessive drinking may lead to nausea, vomiting, diarrhea and other symptoms, and may also lead to acute gastrointestinal diseases, such as gastroenteritis and gastrorrhagia. Secondly, drinking a lot of beer in a short period of time leads to the exuberant secretion of human pancreas, and also easily leads to acute pancreatitis, acute pain in the upper abdomen, nausea, vomiting, diarrhea, fever and other symptoms, which may be fatal in severe cases. Drinking beer every day should not exceed 1000 ml. Although beer can cool off the heat, you must drink it in moderation. Healthy people should drink no more than 1000 ml of beer every day. Liquor and beer should not be mixed together. Many people have dinner with friends, and they are not satisfied with drinking white wine, so they need some beer. Experts remind that beer can not be mixed with liquor, which will accelerate the penetration of liquor alcohol in the whole body, cause strong stimulation to organs such as liver, stomach, intestine and kidney, accelerate alcoholism, and may also cause stomach cramps, acute gastroenteritis and other diseases, which is also harmful to cerebrovascular health. Diabetes patients should not drink beer, otherwise it may increase the blood sugar content in the body. The third culprit: barbecue barbecue+beer is easy to gout. Mr. Liu, 45, often suffers from ankle pain. Recently, the pain has become more and more serious, and it is even difficult to walk. He went to the hospital for orthopedic examination and found no joint lesions. The doctor asked him about his living and eating habits carefully and asked him to check his blood uric acid. The result showed that he had gout. It turns out that Mr. Liu has a generous personality. Eating meat and drinking in a big bowl is his passion, especially in summer. Every day, 20 skewers of barbecue and two or three bottles of beer are dinner. Also, Ms. Chen went to the seaside this summer and really enjoyed a seafood feast for several days. But when I came back, I felt unwell all over. I didn't know it was a gout attack until I saw a doctor. According to the doctor, gout patients like Mr. Liu, who did not see a doctor because of symptoms, are very common because of recent uncontrolled diet, excessive intake of seafood, beef and mutton, and beer, and even gout patients who were diagnosed after their illness worsened. Young and middle-aged men who drink a lot and eat large pieces of meat are high-risk groups of gout. Among them, seafood, barbecue beef and mutton, beer, etc. are all high-purine foods, which are easy to cause acute gout attacks or aggravate the condition. Tip: Eating more vegetables can reduce the risk. Young people should change the combination of barbecue and beer. Those who have no history of gout can choose barbecue and vegetables or beer and vegetables. People with a history of gout should give up beer and barbecue. Barbecue is not suitable for appetizers. In the process of barbecue, not only the utilization rate of protein in food is reduced, but also the carcinogen benzopyrene is produced. When excessive drinking increases the blood lead content, the combination of the above substances in barbecue foods is easy to induce digestive tract tumors. In addition, due to the large amount of drinking in summer, the probability of inducing this disease is often high. The carcinogenicity of barbecue food is related to the amount of food eaten. It is suggested that it should not exceed twice a week and not exceed 100g each time. The fourth culprit: mala Tang and hot pot burn your mouth and stomach. It feels comfortable to eat spicy food in dog days. Hotpot restaurants are also overcrowded, and people's tastes are getting hotter and hotter. Mr. Yang, a white-collar worker, invited some friends to eat mala Tang. He felt that the spicy and slightly spicy dishes were not enough, so he ordered a special spicy cauldron directly. I felt refreshed that day. As a result, I woke up the next morning with a sore mouth and hoarse voice. Cheng, chief physician of the Department of Stomatology of a hospital in Wuhan, said that you should eat less mala Tang in summer. Excessive numbness, acrimony and scald will not only stimulate the oral cavity, esophagus and gastrointestinal mucosa, resulting in congestion and edema, but also may induce digestive system diseases, such as recurrent stomatitis and chronic pharyngitis. People with ulcers, chronic pancreatitis, cholecystitis and upper abdominal surgery should not eat mala Tang. In addition, if the bamboo stick used is not disinfected thoroughly, the bacteria on it may cause food poisoning. Tips Don't be too hot in mala Tang and hot pot. Generally, the oral cavity, esophagus and gastric mucosa can only tolerate the temperature of 50℃-60℃. Too hot food can damage mucosa, leading to acute esophagitis and acute gastritis. Being too fat can easily lead to hyperlipidemia, gastropathy, duodenal ulcer, gallstones, oral ulcers, gingivitis and hemorrhoids. Can't drink hot pot soup for a long time. Purine substances contained in meat and seafood are mostly soluble in soup, so don't drink rinse soup. Otherwise, it is easy to cause gout, joint pain and other symptoms, and even damage renal function in severe cases.
