In winter, the climate is cold, with yin flourishing and yang declining. Under the influence of cold temperature, the physiological function and appetite of human body will change. Therefore, it is very necessary to adjust the diet reasonably, ensure the sufficiency of essential nutrients, improve the cold tolerance and immune function of the elderly, and make them spend the winter safely and smoothly.
First of all, we must ensure the supply of heat energy. The cold climate in winter affects the endocrine system of human body, which increases the secretion of thyroxine and adrenaline, thus promoting and accelerating the decomposition of protein, fat and carbohydrate, increasing the body's cold-proof ability, thus causing excessive loss of heat. Therefore, nutrition in winter should be based on increasing heat energy, and foods rich in carbohydrates and fats can be properly ingested. For the elderly, the intake of fat should not be too much, so as not to induce other diseases of the elderly, but enough protein should be taken, because the decomposition of protein is enhanced, and the human body is prone to negative nitrogen balance. Protein's supply accounts for 15 of the total heat? 17% is the best. Protein should be supplied mainly with high-quality protein, such as lean meat, eggs, fish, milk, beans and their products. Protein contained in these foods is not only easy for human body to digest and absorb, but also rich in essential amino acids with high nutritional value, which can increase human body's cold resistance and disease resistance.
Winter is the off-season of vegetables, and the number of vegetables is small and the varieties are monotonous, especially in northern China. Therefore, often after a winter, the human body appears vitamin deficiency, such as vitamin C deficiency, which causes many elderly people to have symptoms such as oral ulcer, swelling and pain of root, bleeding and constipation. Its prevention and control method should first expand the food source, and the green leafy vegetables are relatively reduced in winter, so you can eat some potatoes, such as sweet potatoes and potatoes. Are rich in vitamin C and vitamin B, especially lack of vitamin A, and red sweet potatoes also contain more carotene. Eating more potatoes can not only supplement vitamins, but also clear away heat and eliminate plague. In addition to Chinese cabbage, cabbage, radish heart, white radish, carrot, bean sprouts, mung bean sprouts, rape and so on. It should also be selected in the main course listed in winter. These vegetables are rich in vitamins. As long as the varieties are changed frequently and matched reasonably, the vitamin demand of the human body can still be supplemented. The cold in winter will also affect the nutritional metabolism of the human body and increase the consumption of various nutrients to varying degrees. Due to the influence of digestion, absorption and metabolism in the body, the elderly often lack potassium, calcium, sodium, iron and other elements. In addition, the inorganic salts discharged with urine in winter increase, which should be supplemented in time. You can eat more foods rich in calcium, iron, sodium and potassium, such as shrimp, shrimp skin, sesame paste, pork liver and bananas. If there is low sodium, it tastes slightly salty when cooking, so it can be supplemented.
Common sense of winter diet:
1. Fear of cold is related to the lack of inorganic salts in the diet. Eat more vegetables with roots.
2. Winter health care should eat "cold" properly, and drinking cold boiled water often has the effect of preventing colds. Drink plenty of water at ordinary times, keep the balance of water metabolism, and prevent chapped skin and invasion of pathogenic fire.
3. Lentinus edodes is delicious and has the effect of preventing and treating influenza. Eating it often can also prevent arteriosclerosis.
Eating radish often in winter can achieve the effects of relieving cough, resolving phlegm, clearing away heat and detoxifying.
5. Eat more fruits and vegetables, such as grapes, radishes, pears, persimmons, lotus seeds, lilies, sugar cane, pineapples and bananas. In order to supplement vitamins and minerals in the body, neutralize excess acidic metabolites in the body, and play the role of clearing away heat and toxic materials and moistening the lungs; Eat more high-protein plant foods such as beans and eat less greasy; It is not advisable to eat more barbecue, so as not to aggravate the symptoms of autumn dryness. Vitamin a can enhance the cold tolerance of human body; Vitamin C can improve the adaptability of human body to cold. Therefore, root vegetables such as sweet potato, lotus root, green onion and potato are rich in minerals and calories, which can also enhance the cold resistance of human body if eaten regularly.
6. If you want to "keep warm" through food in winter, you don't have to eat more hot food. Low temperature will accelerate the metabolism of vitamins in the body and should be supplemented in time in the diet.
7. There is a big temperature difference between morning and evening in winter, so it is necessary to increase clothes in time to prevent catching cold. Eating garlic regularly can prevent colds.
