In the four seasons throughout the year, summer is the most prosperous season of yang in the year. The weather is hot and full of vitality. For people, this is a time when metabolism is strong, and human yang is out of the body, and yin is included. It is also vigorous and active on the surface of the body. In the Yellow Emperor's Internal Classic, the word “Yang Yang in Spring and Summer†means that during the hot summer months, it is necessary to protect the yang in the body. In summer, the body's appetite is reduced, and the consumption of nutrients is large. If the dietary nutrition does not pay attention, it will hurt the body. Then, what principles should be paid attention to in summer diet? First, from the perspective of Chinese medicine, summer diet should eat more sour, salty, cold should not be too cold. In the summer, when the fire is in season, the fire is overwhelming and the lungs are gold. Therefore, the “Golden Helmet Outline†has the saying “Summer is not good for the heartâ€. According to the relationship between the five elements (summer for fire), five elements (summer for long), five internal organs (for heart), and five flavors (for bitterness), the bittersweet substance can also help the heart and lungs, and in the summer it is sweaty. In seasons, when sweating is excessive, there will be more salt loss. If the heart muscle lacks salt, the heart beat will be abnormal. Chinese medicine believes that at this time should eat more sour, solid table, eat more salt to make up the heart. Sour vinegar can not only stimulate the appetite, but also kill germs and prevent gastrointestinal diseases. From the point of view of Yin and Yang, Xiayuefuyin, the diet can not be too cold, such as "the whole body set" said: "Summer heart and kidney failure, although the hot should not eat cold Amoy snow, honey water, jelly, cold porridge Stomach and cold, it must be cholera." Heart Wang kidney failure, that means the external heat inside the cold, because of its external heat inside the cold, so the cold food should not be more food, greedy more than a cold will hurt the spleen and stomach, it is vomiting and diarrhea. Watermelon, mung bean soup, ebony bean soup, although it is the best product for thirst quenching, but not iced food. According to the relationship between the dirty and dirty parts of Chinese medicine, "Kidney's heartless water is cold, and the heartless water is flaming; the heart will have nourishing kidney water, and the kidney will get warm and warm." It is not difficult to see the important relationship between heart and kidney. Second, from the nutritional point of view, summer to add enough protein, vitamins, water, inorganic salts. In the summer, we should pay attention to diet, because when people are in a hot environment, they sweat more, the metabolism of the body increases, and the consumption of nutrients increases. Not only that, summer people's loss of appetite and poor digestion and absorption also limit the normal intake of nutrients, all of which may lead to disorders of the body's nutrient metabolism, and even cause the corresponding nutritional deficiencies or other diseases. So, what are the specific methods for summer diet? 1, to add enough protein. Under high temperature conditions, the human body consumes a lot of energy. The intake of protein should be increased by 10% to 15% on a normal basis. The daily supply must be about 100 grams, and attention should be paid to supplementing lysine. Proteins are good for proteins in fish, meat, eggs, milk and beans. 2, to appropriate vitamin supplements. Increased vitamin metabolism in hot environments, in addition, sweat out of water-soluble vitamins, especially vitamin C, therefore, the body's vitamin requirements in summer than the average standard is 1 times or more than 1 times. In fresh vegetables and summer ripe fruits, such as tomatoes, watermelons, red bayberry, melons, peaches, plums, etc. contain the most abundant vitamin C, vitamin B group in cereals, beans, animal liver, lean meat, eggs, including the most In summer, people can properly supplement these foods. 3, to reasonably add water and inorganic salts. When the body sweats a lot or the body temperature is too high, not only the body's moisture is insufficient, but also a large amount of sodium and potassium are lost. Sodium deficiency can cause severe water shortages, so add water and inorganic salts. Moisture supplementation is best done in small amounts and multiple times, which will allow the body to slow down perspiration and reduce evaporation. The ancients had warned: "Do not want to be thirsty and drink, drink too much", meaning that drinking water to be thirsty, do not drink too much thirst, which is a scientific method to prevent thirsty drink. Third, do not drink water before and during meals. Drinking water before and during meals will dilute the digestive juice, which is not conducive to the digestion and absorption of food. The fourth is to drink some water when you get up in the morning, which can supplement the water consumed in the night, reduce the blood concentration, promote blood circulation, and maintain the normal level of body fluids.
