■ Foods rich in vitamins: Low temperature will accelerate the metabolism of vitamins in the body and should be supplemented in time. For example, vitamin A can enhance the cold tolerance of human body; B vitamins are beneficial to normal metabolism; Vitamin c can improve the adaptability of human body to cold; Vitamin E can make blood circulation smooth and adjust the hormone balance in the body. Therefore, the intake of foods rich in vitamin A such as animal liver, carrots and pumpkins, foods rich in B vitamins such as fresh rice flour and coarse grains, foods rich in vitamin C such as fresh vegetables and fruits, nuts such as sunflower seeds, walnuts and black sesame seeds, and foods rich in vitamin E such as marine fish and bean products can be increased. ?
■ Foods rich in minerals: Fear of cold is related to the lack of minerals in the diet. Carrot, sweet potato, green vegetable, Chinese cabbage, lotus root, cauliflower, green onion, potato and other root vegetables contain a lot of minerals, which can be mixed with meat to keep out the cold. You can eat more calcium-rich foods such as milk, bean products, shrimp skin, oysters, sardines, shrimp, etc. Regular consumption is also of great benefit to enhancing the cold resistance of the human body. ?
■ Foods rich in iodine: Iodine is an important raw material for the synthesis of thyroxine. Thyroxine can promote protein, carbohydrate and fat in the body to be converted into energy, thus generating heat energy and resisting cold. If the body lacks iodine for a long time, the raw materials for synthesizing thyroxine are insufficient, and the body's ability to keep out the cold will be reduced. Therefore, you can eat more iodine-rich foods such as kelp, seaweed, Nostoc flagelliforme, jellyfish and shellfish. In addition, foods rich in amino acids such as black sesame seeds, sunflower seeds, dairy products and leafy vegetables also help to improve the body's ability to resist cold. ?
■ Foods rich in iron: Iron is an important raw material for hematopoiesis, and red blood cells in the blood are responsible for the transportation and metabolism of oxygen in the body. To turn protein, carbohydrates and fats into heat, we need enough oxygen to "burn" them. If the body lacks iron, it is easy to suffer from iron deficiency anemia; Without the "tools" to transport oxygen, the final result is that the heat is not enough and it is easy to feel cold. Many young women are particularly afraid of cold. In winter, even in a heated room, their hands and feet are often cold, and insufficient iron intake is one of the important reasons. Therefore, women who are afraid of cold should eat more iron-rich foods in winter, such as animal liver, beef, fish, eggs, black fungus, jujube, milk and bean products, which can improve their resistance to cold.
