Eating those things in winter can help keep out the cold.

Cold has many effects on human body. Firstly, it affects the hormone regulation of the body and accelerates the metabolic decomposition of protein, fat and carbohydrate, especially fat; Secondly, it affects the digestive system of the body, making people increase their appetite and digest and absorb it better; Third, it affects the urinary system of the body, and the corresponding increase in urination increases the loss of minerals such as calcium, potassium and sodium. Therefore, these changes need to be reasonably regulated by corresponding nutrients to prevent the above-mentioned physiological changes in the winter environment. The specific requirements should be as follows:

(1) Increase the intake of warm food.

In the cold winter, people often feel uncomfortable because of the cold, and some people are particularly afraid of the cold because of the weak yang in their bodies. Therefore, in winter, it is necessary to use cold-proof food to keep warm and recuperate, so as to warm and nourish the whole body tissues, enhance physical fitness, promote metabolism, improve cold-proof ability, maintain the functional activities of body tissues, resist exogenous pathogens and reduce the occurrence of diseases. Traditional Chinese medicine believes that warm tonic foods should be eaten in winter, such as mutton, dog meat, turtle, sparrow, shrimp, pigeon, quail, sea cucumber, medlar, leek, walnut and glutinous rice.

(2) Increase the intake of heat-producing food.

Due to the cold climate in winter, the human body consumes more energy every day to adapt to the cold environment, so it is necessary to increase the intake of thermogenic nutrients. Thermogenic nutrients mainly refer to protein, fat and carbohydrates. Therefore, we should eat more foods rich in these three nutrients, especially increase the intake of fat. For example, we should pay attention to the intake of fat when eating meat dishes and put more cooking oil.

(3) Supplementing essential methionine

Methionine can provide a series of methyl groups necessary to adapt to cold tolerance through transfer. The cold climate increases the excretion of creatine in human urine and accelerates the metabolism of fat. The heat released by the oxidation of creatine, fatty acids and phospholipids in mitochondria needs methyl. Therefore, we should eat more methionine-containing foods in winter, such as sesame seeds, sunflower seeds, dairy products, yeast, leafy vegetables and so on.

(4) Eat more foods rich in vitamins.

Due to the cold climate, the oxidation heat production of human body is strengthened, and the vitamin metabolism of human body has also changed obviously. For example, increase the intake of vitamin A and enhance the cold tolerance of the human body. Increasing the intake of vitamin C can improve the adaptability of human body to cold, which has a good protective effect on blood vessels. Vitamin A mainly comes from animal liver, carrots, dark green vegetables and other foods, and vitamin C mainly comes from fresh fruits and vegetables and other foods.

(5) Appropriate mineral supplement.

People's fear of cold is also related to the quality of minerals ingested by the body. For example, the content of calcium in the human body can directly affect the flexibility and excitability of the heart, blood vessels and muscles, and calcium supplementation can improve the cold resistance of the human body. Foods rich in calcium include milk, bean products and kelp. Salt is also very important for human body to keep out the cold, which can enhance the heat-producing function of human body. Therefore, in winter, it is mainly heavy taste and pungent heat, but it should not be too salty, and the daily salt intake should not exceed 6 grams at most.

(6) Pay attention to hot food

In order to adapt the human body to the cold environment, we should eat hot meals and hot dishes to absorb more energy to keep out the cold. You might as well arrange more hot soup on the dining table, which will not only increase your appetite, but also eliminate the cold feeling.
