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 food with cold-proof function 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 external evils 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.

Meat: dog meat, mutton, beef and venison have better cold-proof effect. They are rich in protein, carbohydrates and fat, and have the effects of tonifying kidney, strengthening yang, warming middle warmer, benefiting qi, promoting blood circulation and removing blood stasis. Eating these meats can accelerate the metabolism of yang deficiency constitution and enhance endocrine function, thus achieving the effect of keeping out the cold.

Rhizome: Medical researchers have found that people's fear of cold is related to the lack of inorganic salts in the body. Lotus root, carrot, lily, sweet potato, green vegetables and Chinese cabbage are all rich in inorganic salts, so these foods may as well be eaten with other foods.

Spicy food: Chili contains capsaicin, ginger contains aromatic volatile oil, and Chili contains piperine. Eating these spicy foods can dispel wind and cold, promote blood circulation and raise body temperature.

Iodine-containing foods: kelp, seaweed, sea salt, Nostoc flagelliforme, jellyfish, clams, Chinese cabbage, spinach, corn and other iodine-containing foods can promote the secretion of thyroid hormones. Thyroid hormone has thermogenic effect, which can accelerate the oxidation process of most tissues and cells in the body (except brain, gland and uterus), increase thermogenesis, increase basal metabolic rate, strengthen skin blood circulation and resist cold.

Three recipes:

1. Fried mutton with shredded ginger

Slice the mutton. Shred ginger.

Add a little oil to the pot and bring it to a high fire. When the oil smokes, add pepper and star anise, stir-fry until fragrant, add shredded ginger, stir-fry, add mutton slices, add salt and monosodium glutamate, and pour sesame oil out of the pot.

Add water to the pot, add mutton, onion, ginger and aniseed and cook together. When it is half cooked, add jujube, medlar and salt, and then cook. If you don't like the taste of mutton, you can add one or two pieces of orange peel to increase dates to reduce the smell.

3. Three spice peppers

Red pepper (choose pepper varieties according to the spicy degree of food), put it on the fire and dry it until it is close to burnt; Peanuts, fried until crisp (sesame seeds are also acceptable); Bake the scallion on the fire until the outer layer is burnt, and peel off the outer layer.

Mash the above three raw materials in a mortar, then mix them together and add salt and monosodium glutamate.
