The weather is hot, what should we pay attention to in life?

Every hot summer, many people have poor appetite, decreased digestive function, and are prone to fatigue, epigastric discomfort and other symptoms, and some people are also prone to gastrointestinal diseases. This is because people sweat more in hot days, and water, sodium chloride and water-soluble vitamins (mainly vitamin B 1 and vitamin C) in the body will also be lost with sweat, causing water and salt metabolism disorder; It also reduces the chloride ion reserve necessary for the formation of gastric acid in the blood, leading to the reduction of gastric acid; Excessive sweating can also cause excessive loss of potassium ions in the body; In addition, in order to dissipate heat, blood is mostly concentrated on the body surface, while the blood supply to the gastrointestinal tract is reduced; Excessive heat storage and sweating in the body will also reduce the activities of various digestive enzymes in the gastrointestinal tract. These bad changes will directly or indirectly cause loss of appetite and digestive dysfunction. If it is not handled well, it will also induce other gastrointestinal diseases. Therefore, in the hot summer, we must pay attention to diet regulation and take corresponding effective and scientific measures.

First, eat bitter food properly.

As the saying goes, happiness comes from "bitterness", and alkaloids contained in bitter food have pharmacological effects such as relieving summer heat, promoting blood circulation and relaxing blood vessels. Eating some bitter food in hot weather can not only clear the heart, relieve annoyance and refresh the mind, but also stimulate the appetite, strengthen the spleen and benefit the stomach. Bitter foods such as bitter gourd, bitter vegetables, tea and coffee can also be selected as appropriate. It should be noted that eating bitter food should not be excessive, otherwise it may cause nausea, vomiting and other symptoms.

Second, drink some cold drinks properly.

Due to the influence of high temperature, the human body will produce a series of physiological reactions, leading to listlessness and loss of appetite. At this time, if you can arrange your diet reasonably and eat some cold drinks properly, you can not only quench your thirst, but also help digestion, with balanced nutrition and good health. You shouldn't eat too much cold drinks and drinks. Cold food such as ice cream and ice brick is made of milk, egg powder, sugar and other materials, so you can't eat too much. Overeating will reduce the gastrointestinal temperature, cause irregular contraction, and induce abdominal pain, diarrhea and other diseases. There are many kinds of drinks, and drinking too much will affect appetite, seriously damage the spleen and stomach or lead to gastrointestinal dysfunction.

Third, pay attention to supplement salt and vitamins.

In midsummer, the human body sweats more and loses more sodium chloride, so we should pay attention to supplementing salt while replenishing water. Drink some salty boiled water every day to keep the acid-base balance and osmotic pressure in the body relatively stable. Nutritionists also suggest that it is best to supplement vitamin B 1, vitamin B2 2 mg and calcium 1 g every day in high temperature season, which can reduce the consumption of sugar and tissue protein in the body and is beneficial to human health. Therefore, we should eat more foods rich in the above nutrients in summer, such as watermelon, cucumber, tomato, beans and their products, animal liver, shrimp skin and so on. You can also drink some juice.

Sweating more in summer, and more potassium ions are lost with sweat, leading to hypokalemia, which will cause fatigue, dizziness, headache, loss of appetite and other symptoms. The most effective way to prevent potassium deficiency in hot weather is to eat more foods containing potassium. Fresh vegetables and fruits contain more potassium, so you can eat more strawberries, apricots, lychees, peaches and plums. Vegetables include green onions, celery, edamame, etc., and are also rich in potassium. Tea also contains more potassium. Drinking more tea in hot weather can relieve summer heat and supplement potassium, killing two birds with one stone.

Fourth, food hygiene.

Food hygiene is particularly important in summer, and good food hygiene and personal hygiene habits must be developed. Don't buy spoiled food ingredients; It is best to cook and eat now; Raw fruits should be cleaned and disinfected; When cooking cold dishes, add garlic paste and vinegar, which can not only flavor, but also sterilize and stimulate appetite; Even if the weather is hot, you should not be too greedy in diet to prevent pathogenic microorganisms from taking advantage of it.

Fifth, it should be light and avoid hot and dry.

Diet, hot weather, the principle is tonic, spleen, summer heat, dampness. Fat, sweet and hot products should not be eaten, and light and nourishing food should be chosen, such as duck, shrimp, crucian carp, lean meat and edible fungi (mushrooms, mushrooms, Pleurotus ostreatus, tremella, etc. ) and coix seed. After reasonable cooking, it can be made into all kinds of delicious food, which can stimulate appetite, supplement nutrition, and relieve summer heat and keep fit. In addition, you can also eat mung bean porridge, bean porridge, lotus leaf porridge, mint porridge and other "antidote porridge", which has a certain effect of dispelling summer heat and promoting fluid production and tastes delicious.

In high temperature climate, protein metabolism in human body is accelerated and energy consumption is increased. Therefore, the supply of protein must be appropriately increased, and the daily intake is 100- 120g, of which more than half should be high-quality protein such as fish, lean meat, chicken, eggs, milk and bean products to meet the needs of body metabolism in summer. At the same time, in order to increase appetite, we should try our best to eat well, pay attention to the increase and change of color varieties, and choose some spicy condiments in moderation.
