Winter diet principles: In winter, the climate is cold and yin is strong and yang is weak. The human body is affected by cold temperatures, and its physiological functions and appetite will change. Therefore, it is very necessary to adjust the diet reasonably to ensure the adequacy of essential nutrients for the human body to improve the cold tolerance and immune function of the elderly and enable them to survive the winter safely and smoothly. First, the supply of heat energy should be ensured. The cold climate in winter affects the human body's endocrine system, increasing the body's secretion of thyroxine, adrenaline, etc., thereby promoting and accelerating the decomposition of the three major types of heat source nutrients, protein, fat, and carbohydrate, to increase the body's ability to withstand the cold, thus causing The body loses too much heat. Therefore, winter nutrition should focus on increasing heat energy, and you can appropriately consume more foods rich in carbohydrates and fats. For the elderly, they should not consume too much fat to avoid inducing other diseases in the elderly, but they should consume sufficient protein, because protein catabolism and metabolism are enhanced, and the human body is prone to negative nitrogen balance. The amount of protein supplied should account for 15-17% of the total calories. The protein supplied should be mainly high-quality protein, such as lean meat, eggs, fish, dairy, beans and their products. These foods contain The protein is not only easy for the human body to digest and absorb, but is also rich in essential amino acids and has high nutritional value, which can increase the body's cold tolerance and disease resistance. Winter is the off-season for vegetables. The number of vegetables is small and the varieties are monotonous. This phenomenon is more prominent especially in northern my country. Therefore, after a winter, the human body often suffers from vitamin deficiency, such as lack of vitamin C, which causes many elderly people to suffer from oral ulcers, tooth root swelling and pain, bleeding, constipation and other symptoms. The prevention method should first expand food sources. Green leafy vegetables are relatively reduced in winter. You can eat some potatoes, such as sweet potatoes, potatoes, etc. appropriately. They are rich in vitamin C and vitamin B, especially those lacking vitamin A. Red sweet potatoes also contain more carotene. Eating more potatoes can not only supplement vitamins, but also clear away internal heat and remove plague toxins. In addition, among the main vegetables on the market in winter, in addition to Chinese cabbage, you should also choose cabbage, Xinlimei radish, white radish, carrot, soybean sprouts, mung bean sprouts, rapeseed, etc. These vegetables are rich in vitamins. As long as you change the varieties frequently and mix them appropriately, you can still supplement your body's vitamin needs. The cold in winter can also affect the body's nutritional metabolism, causing the consumption of various nutrients to increase to varying degrees. Due to the influence of digestion and absorption and body metabolism factors, the elderly often lack potassium, calcium, sodium, iron and other elements. In addition, the amount of urine in the human body increases in winter, so the amount of the above-mentioned inorganic salts excreted in the urine also increases. Therefore, they should be removed in time. be supplemented. You can eat more foods rich in calcium, iron, sodium, potassium, etc., such as dried shrimps, dried shrimps, sesame paste, pork liver, bananas, etc.

If you have low sodium and the taste is a little salty when cooking, you can add more
