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

If there is no reasonable arrangement on diet in hot weather, it is very easy to cause various health problems. In particular, we should prevent the following phenomena: there is no appetite in high temperature weather, so many people will feel no appetite in high temperature weather, so their appetite will be reduced, and they will even be unwilling to eat and avoid eating. In fact, in hot weather, we should pay more attention to the balanced intake of food. Because hot weather itself will increase our body's demand for various nutrients, especially vitamins and minerals, if we can't get reasonable supplements in our diet, we are more prone to health problems such as heatstroke and limb fatigue. Eat only fruit, not dinner. Many people like summer, because summer fruits are rich in variety, delicious and can relieve summer heat. Especially in sauna days, food can't arouse people's appetite, so simply take fruit instead. When the fruit is full, dinner will naturally be saved. Although fruit tastes delicious, it is a good product to relieve summer heat and thirst, but excessive consumption of fruit will inevitably affect the normal intake of other foods, and it is difficult to ensure a balanced diet and reasonable nutrition. If you only eat fruit and don't eat dinner, your body's nutrition and energy will not be supplemented, and you will naturally feel weak. After all, the human body needs a variety of nutrients every day, and fruits can only provide carbohydrates, some vitamins, minerals and dietary fiber. The content of protein and other nutrients is very limited, so long-term use of fruit instead of dinner will inevitably affect health. Use iced drinks and ice cream to relieve the summer heat. Many people think that summer is hot, it is easy to get angry, feel dry, thirsty and irritable, and should eat more cold food. Therefore, iced drinks, ice cream, popsicles and ice cream have become the best products for these sheds to relieve summer heat. In fact, eating cold food will make the submucosal blood vessels of the digestive tract contract rapidly, reduce the absorption capacity, weaken the gastrointestinal function, which is not conducive to supplementing water and nutrition, and will also reduce the resistance of the gastrointestinal tract, which will easily lead to diarrhea and gastroenteritis. At the same time, due to the reduced blood supply to the digestive system and poor heat dissipation, people feel hotter and more irritable. Many people often eat too many cold drinks. Because they are in a state of sweating and high fever, sudden high temperature and sudden cooling can easily stimulate the throat and stomach, causing sore throat and stomach discomfort. Patients with cardiovascular diseases, after eating a lot of cold drinks, can reflexively cause coronary artery spasm and contraction, induce angina pectoris and cold drinks to stimulate oral and esophageal mucosa, and can also reflexively cause head vasospasm, numbness of palate, tongue and head, and then cause pulsating headache and nausea with vasodilation. Especially for people with weak stomach and intestines on weekdays, they should pay more attention to food temperature and strictly limit cold food and cold drinks. Especially for children, eating more cold drinks will affect the body's resistance and cause unnecessary throat and gastrointestinal diseases. In fact, the heatstroke prevention and cooling effect of cold food and cold drink is not only far less than that of hot tea, mung bean soup and other drinks. To relieve summer heat, you should drink a drink slightly higher than your body temperature to increase gastrointestinal blood flow, improve the absorption of water and nutrients, and improve your resistance. Relieve the summer heat by drinking a lot of beer. Many people think that drinking more beer can relieve the heat in summer. Drinking beer in hot weather does have a cool feeling, especially when drinking cold beer. The feeling of penetrating the heart and spleen makes many people love beer. However, this feeling is only a temporary pleasure of the mouth, digestive tract and taste. People who drink too much beer often feel thirsty, thirsty and feverish in less than half an hour. Beer cannot fundamentally solve the problem. In addition, beer has high energy, so people call it "liquid bread". If you rely on beer to relieve the heat, it is estimated that the heat has not been solved, and the beer belly will come! To clear away heat and prevent heatstroke, you should eat more cool fruits and vegetables such as bitter gourd. When many people talk about clearing away heat and preventing heatstroke, they only think of "cool" fruits and vegetables such as bitter gourd, cucumber and wax gourd, staring at them every day, and they like to eat cold salad best, and rarely cook with oil. Although these cool vegetables contain vitamin C and potassium, the content of other nutrients is low. From the content of carotene, vitamin B2, folic acid, calcium, magnesium, etc. , are ranked lower, and the antioxidant components and dietary fiber content are also insufficient. If you cook with little oil, it will make it difficult to effectively absorb fat-soluble nutrients in vegetables. Although cool fruits and vegetables are low in calories, they will also reduce the thermal efficiency and energy consumption of human body. If you eat too much cold food, it may reduce the ability of digestion and absorption, thus aggravating the nutritional deficiency in summer. In addition, cool food will reduce the "internal heat" of the human body, but it usually means that the heat dissipation function of the human body is reduced. For example, girls with cold hands and feet on weekdays, eating cold food will make their bodies cooler. Traditional Chinese medicine is difficult to explain in biological terms, but the overall effect of "clearing fire" is to reduce human calorie consumption. In this way, eating the same food calories will make you less likely to lose weight. People with weak digestive function, overeating cold food will also cause accelerated intestinal peristalsis and even diarrhea, thus further reducing the efficiency of nutrient absorption. Generally speaking, the summer weather is hot and the sun is exposed, which requires enough antioxidant components and multivitamins. When choosing vegetables, pay special attention to vegetables with dark green leaves. The protein, vitamins, minerals and antioxidant components of dark leafy vegetables are higher than those of light leafy vegetables, so the comprehensive nutritional value is also high. It is best to eat about 200 grams of dark green leafy vegetables every day in summer, such as spinach, amaranth, pea tip, oily wheat, kale and so on. , plus 200 ~ 300 grams of other light-colored vegetables, you can get the most comprehensive vegetable nutrition. Of course, the way vegetables are cooked is also very important. It should not only attract appetite, but also have a light taste. When cooking green leafy vegetables, stir-frying with a little oil or scalding with a little sesame oil to make cold salad is an ideal cooking method in summer.
