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.

Beer: Beer is rich in amino acids, protein, sugar, minerals and other ingredients beneficial to human health, and is known as "liquid bread".

In addition, bitter foods such as bitter vegetables, tea, coffee, etc. 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.

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.

Don't eat too much cold drinks and beverages.

When the weather is hot, eating some cold drinks or drinking some drinks in moderation can play a certain role in relieving summer heat and cooling down. 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.

Don't forget to supplement potassium in summer.

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.

Pay attention to 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.

Summer is the best time to make up for it

In the aspect of diet nourishing, the principle of nourishing and strengthening the spleen, removing summer heat and removing dampness is adopted in hot days. 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 addition, in high temperature environment, 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 human metabolism in midsummer. 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.
