"Three volts" is a general term for the first, middle and last three volts. According to the climate law of China lunar calendar, predecessors have long stipulated that "the third Geng day from long summer to the future is the first volt, the fourth Geng day is the second volt, and the first Geng day after beginning of autumn is the last volt." The dog days are a period of time between the light summer and the great summer in China. This is the hottest, wettest and sultry day of the year. What food do you eat in dog days? As the saying goes, "it's hot in dog days." The dog days are the hottest day in a year, and it is also a humid and sultry day. At this time, my appetite is declining. What food should I eat on a hot day? Pay attention to a light and digestible diet, eat less greasy and spicy food, be careful, calm down, calm down, and practice both inside and outside. What to eat in dog days? Chinese medicine believes that the stomach is the foundation of the day after tomorrow. In summer, people often feel loss of appetite, and the function of spleen and stomach is relatively slow. At this time, they might as well eat some fresh fruits and vegetables. The nutrients in fresh fruits and vegetables are generally half cellulose and half sugar, which can not only effectively supplement the necessary energy and water for human body, but also make people eat for a long time. Carrots, lemons and amaranth are the first choice. Eating more wild vegetables and fruits in season is of great benefit. But be careful not to eat cold or unclean food to avoid dysentery and diarrhea. Supplementing qi and removing fire in hot summer not only brings us physical discomfort, but also easily causes more and more people to get angry, which is manifested as emotional irritability, anxiety, excitability and insomnia. These symptoms are called "summer mood disorder" in medicine. Therefore, "removing fire" is also a compulsory course for summer food supplement. The best choice for summer food is bitter gourd, tomatoes and other cool fruits and vegetables. At the same time, milk is slightly cold, which can replenish water, nourish yin and reduce fever, and is also a good product for "dispelling fire". Dog meat and duck meat is the best way to make up for it in summer. Ancient sour and sweet scholars thought that "summer dampness should be cleared up." In hot summer, people like cold drinks and drink plenty of water, so that moisture invades the human body, while external moisture enters the body, making water wet and invigorating the spleen, lifting the spleen and stomach, causing digestive dysfunction, stagnant water and loss of appetite. According to the viewpoint of TCM health preservation, dryness and dampness in summer do great harm to the spleen, while bitter food has the effect of purging dryness and should not be eaten more, so it is advisable to eat more sweet and cold or sweet and cold in daily diet. And in summer, you return to your heart, but your heart likes cold and wants to eat sour, so you should eat more sour in summer. Such as pineapple and watermelon. The theory of hydrating health care pays attention to "yin and yang and five elements" and "harmony between man and nature" Winter is cloudy, summer is sunny, and summer is a season of vigorous yang. It is also a time when the human body is full of yang, which tends to rise in summer, and the cold in the body is in a state of easy solution. In dog days, people will sweat a lot when they are working or exercising a little, and then they will have a strong thirst. Therefore, hydrating health has become the top priority in dog days. Precautions in dog days 1, you must eat breakfast. Breakfast is the source of energy for a day. Eating breakfast can make you know better, make your mind bright, and improve your metabolism throughout the day. What should I eat for breakfast? If you are used to eating porridge in the morning, the dishes are better, including eggs, floss, fresh fish slices and vegetables, which can be paired with wheat buns and steamed bread. Don't just eat bread for breakfast. Breakfast must be accompanied by high-quality protein food, such as milk, eggs, cheese, meat and so on. The optimum intake ratio of starch and protein is 1: 1. For example, breakfast is mainly two pieces of bread, with ham, cheese, 1 ~ 2 eggs, a few pieces of cucumber or tomato and 65438+. 2. What should I have for lunch? The biggest function of lunch is to replenish enough energy for the body, relieve the fatigue of working all morning and "refuel" for the afternoon. Therefore, you can eat more high-protein foods for lunch, such as rice, beef, chicken, bean products, as well as various green leafy vegetables, yogurt, fresh fruits and so on. Rice is the best staple food, which can provide us with enough carbohydrates. If possible, you can eat some whole grains rice to protect your stomach. Beef and chicken can supplement us with high-quality animal protein; Soybean products containing high-quality plant protein can supplement nutrition more comprehensively; Vegetables provide us with a lot of vitamins, minerals and dietary fiber; Fresh fruit can make up for some nutrients lost in the diet. Many people like to eat high-sugar and high-fat foods for lunch, such as French fries, hamburgers, fried chicken and other fast food. They can stimulate the secretion of insulin and bile, reduce the oxygen carrying capacity of blood, and make people easily tired. 3, dinner should not be too rich, dinner should be light and simple, of course, we should also pay attention to maintaining nutrition. The best choice for dinner: noodles, rice porridge, fresh corn, beans, vegetarian stuffed buns, side dishes and fruit platters. It is also good to drink a small glass of rice wine or red wine with meals occasionally. Pay attention to the food mix, coarse and fine, dry and thin, meat and vegetables, cold and hot. Food collocation is closely related to nutritional balance. A bowl of instant noodles can only provide oil, a little protein and carbohydrates, so it is best to match a piece of fruit, a piece of meat or bean products to supplement protein, vitamins and cellulose. For the choice of a day's diet, such as eating hamburgers and fried chicken for lunch, you should eat some light food for dinner, especially vegetables. Poultry meat refers to chicken, duck, goose, pigeon, quail and other meat. The protein nutrition of poultry meat is almost the same as that of roughed meat, but the saturated fatty acid content is lower than that of livestock meat. Experts believe that eating poultry meat is more beneficial to health than eating livestock meat. Fish, fish muscle contains protein 15%-20%, and because muscle fiber is short and smooth, it is easier to digest than auspicious meat and miscellaneous meat. More importantly, the fat content of fish is only 1%-3%, and the main components are long-chain polyunsaturated fatty acids, such as EPA of eicosapentaenoic acid and DHA commonly known as "brain gold", accounting for 80% of the total fatty acids in marine fish. It is worth noting that EPA can reduce blood lipids and prevent coronary heart disease. DHA is necessary for the development of brain and retina of fetus and baby, so fish should be the first choice when choosing meat food. Vegetables contain a variety of minerals, vitamins and dietary fiber, which play an important role in human physiological activities. Vegetables can be roughly divided into three categories: leafy vegetables (such as Chinese cabbage, amaranth and Chinese flowering cabbage), melon eggplant (such as green pepper, cucumber and tomato) and roots (such as potatoes and carrots). Vegetables can provide vitamins such as folic acid, carotene and B vitamins. Among them, vitamin C, carotene and folic acid are high in dark leafy vegetables such as yellow, red and green. Green leafy vegetables are rich in minerals; However, oxalic acid in some vegetables (amaranth, spinach, cabbage, etc. ) will affect the absorption of the human body, so when cooking these vegetables, you should first blanch them with boiling water to remove oxalic acid. Experts suggest that adults should consume 500 grams of vegetables every day, of which 2/3 are leafy vegetables and 1 /3 are melons, eggplants and roots.
