The cold in winter affects the endocrine system of human body, which increases the secretion of thyroid hormone, adrenaline and other hormones, thus promoting and accelerating the decomposition of protein, fat and carbohydrates, enhancing the body's ability to keep out the cold, thus causing excessive loss of heat. Therefore, increasing heat energy should be the main way to supplement nutrition in winter.

Winter diet should be supplemented with thermogenic nutrients, such as carbohydrate, fat, protein, etc., to improve the body's tolerance to low temperature. In addition, foods rich in protein should be supplemented, such as lean meat, chicken and duck meat, eggs, fish, milk, beans and their products.

Therefore, some "fat, sweet and delicious" foods can be appropriately added to the daily diet in winter.

Vitamin C can improve the adaptability of human body to cold, and has a good protective effect on blood vessels, so we should pay attention to the intake of fresh vegetables and fruits.

Medical research shows that people's fear of cold is closely related to the lack of inorganic salts in diet. Experts suggest that you should eat more vegetables with roots in winter, such as carrots, lilies, sweet potatoes, lotus roots, vegetables and Chinese cabbage, because the roots of vegetables contain more inorganic salts.

Tonifying to keep out the cold in winter, such as ignoring the physiological cold tolerance of human body, relying on food to keep out the cold blindly, and eating too much high-calorie and high-fat food and alcohol. It is easy to cause and aggravate cardiovascular diseases. Therefore, we should insist on proper exercise in winter, such as playing Tai Ji Chuan, walking and ball games, which can promote metabolism, speed up blood circulation, enhance digestion and absorption of nutrients in gastrointestinal tract, and truly achieve the goal of eating out benefits.
