What foods should the elderly eat to keep out the cold in winter?

　　Vitamin-rich foods

　　Low temperature will accelerate the metabolism of vitamins in the body and should be supplemented in time in the diet. For example, vitamin A can enhance the body's ability to withstand cold; B vitamins are beneficial to normal metabolism; vitamin C can improve the body's ability to adapt to cold; vitamin E can smooth blood circulation and adjust hormone balance in the body. Therefore, you can increase your intake of foods rich in vitamin A such as animal liver, carrots, and pumpkins, foods rich in B vitamins such as fresh rice noodles, whole grains, and foods rich in vitamin C such as fresh vegetables and fruits, nuts such as sunflower seeds, walnuts, and black sesame, and foods rich in vitamin E such as marine fish and soy products.

　　mineral-rich foods

　　Sensitivity to cold is related to a lack of minerals in the diet. Carrots, potatoes, green vegetables, Chinese cabbage, lotus root, cauliflower, scallions, potatoes and other root vegetables contain a large amount of minerals. They can be mixed with meat to keep out the cold. You can eat more milk, soy products, shrimp skin, oysters, sardines, shrimp and other calcium-rich foods. Regular consumption is also of great benefit to enhancing the body's cold resistance.

　　Foods rich in iodine

　　Iodine is an important raw material for the synthesis of thyroxine. Thyroxine can promote the conversion of proteins, carbohydrates, and fats in the body into energy, thereby producing heat energy and resisting cold. If the body is deficient in iodine for a long time and the raw materials for synthesizing thyroxine are insufficient, the body's ability to resist cold will be reduced. Therefore, you can eat more iodine-rich foods such as kelp, seaweed, nostoc, jellyfish, and shellfish. In addition, foods rich in amino acids such as black sesame seeds, sunflower seeds, dairy products, and leafy vegetables can also help improve the body's ability to withstand cold.

　　Iron-rich foods

　　Iron is an important raw material involved in hematopoiesis. Red blood cells in the blood are responsible for the transport and metabolism of oxygen in the body. To turn proteins, carbohydrates, and fats into calories, you need sufficient oxygen to "burn" them. If the body is deficient in iron, it is easy to suffer from iron deficiency anemia ; And without the "tool" to transport oxygen, the final result is insufficient heat production and it is easy to feel cold. many young female I am particularly afraid of the cold. In winter, my hands and feet often feel cold even in a heated room. 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, jujubes, dairy, soy products, etc., which can improve their resistance to cold.
