Winter diet tips
1. Eat more staple foods and eat mutton, Chinese wolfberry and sea cucumber. Should be warm goods, in order to take the meaning of the yin and yang, such as protein, fat and carbohydrates are called heat-producing nutrients. Therefore, in winter, we must appropriately increase the intake of staple foods and oils to ensure the supply of quality protein. Dogs, mutton, beef, chicken, venison, shrimp, pigeons, cockroaches, sea cucumbers and other foods are rich in protein and fat, produce more calories, and have the best effect of keeping warm. 2. The fear of cold is related to the lack of calcium and iron. People are afraid of cold and the body's intake of certain minerals is less related. Such as calcium content in the human body, can directly affect the myocardium, blood vessels and muscle flexibility and excitability; iron deficiency in the blood is an important cause of iron deficiency anemia, often showing low calorie production, low body temperature and so on. Therefore, supplementing foods rich in calcium and iron can improve the body's ability to keep out the cold. Calcium-containing foods mainly include milk, soy products, kelp, seaweed, shells, oysters, sardines, shrimp, etc.; iron-containing foods are mainly animal blood, egg yolks, liver, soybeans, sesame, black fungus and red dates. 3. Kelp and seaweed can promote thyroid hormone secretion and produce heat. Thyroid hormones in the human body are called thyroid hormones, which can accelerate the oxidation of many tissues in the body, increase the body's heat production, increase the basal metabolic rate, accelerate the blood circulation of the skin, and resist cold and cold, while food containing iodine can Promote thyroid hormone secretion. Iodine-rich foods are: kelp, seaweed, seaweed, jellyfish, spinach, Chinese cabbage, corn and so on. 4. Animal livers and carrots can increase cold resistance. The cold climate changes the body's vitamin metabolism significantly. Increased intake of vitamin A and vitamin C can enhance cold resistance and adaptability to cold, and have a good protective effect on blood vessels. Vitamin A mainly comes from animal livers, carrots, dark green vegetables, etc. Vitamin C comes mainly from fresh fruits and vegetables. V. Nuts provide the necessary elements of cold resistance in the human body. Cold weather increases the demand for methionine in the body. Methionine can provide a series of methyl groups necessary for adapting to the cold through transfer. Therefore, more food containing methionine should be taken in winter. Such as chestnut, sesame, sunflower seeds, black beans, black rice and so on. Six. Eat spicy can be cold. Pepper contains capsaicin, ginger contains aromatic essential oils, and pepper contains piperine. They are all spicy foods, eat more in the winter, not only can increase appetite, but also promote blood circulation, improve the ability to keep out the cold. 7. Drinking a small glass of wine for dinner every day in the winter will greatly benefit the middle and old aged people. 2004-2021 New Laser Distance Sensor
