A few cold days, the same is wearing a coat, wearing a cotton cap, some people do not seem to be afraid of cold, full of firepower, while some people are always frozen, cold hands and feet. In addition to physical reasons, diet can also affect a person's ability to resist cold. As we all know, the three major nutrients of protein, fat and carbohydrate can be converted into energy in the human body, which helps to protect against cold.
Although the following micronutrients cannot be converted into energy, they are involved in energy metabolism. If they are lacking, they will reduce the body's ability to keep out the cold. Those who are afraid of cold should pay attention to supplement.
Vitamin C, representing food: fresh dates, kiwi. This nutrient is closely related to the adaptability to the cold. Studies have shown that ingesting large amounts of vitamin C can significantly reduce the rectal temperature drop caused by cold, and can alleviate the excessive stress response of the adrenal gland and enhance the body's tolerance to cold. Dark vegetables such as bell peppers and tomatoes, as well as fruits such as citrus and lemon are also rich in vitamin C.
B vitamins, representing food: coarse grains, canola. Most B vitamins play a coenzyme role in the body and play an important role in the metabolism of carbohydrates, fats and proteins. Vitamin B1, vitamin B2, and niacin are all closely related to energy metabolism. Vitamin B1 is mainly found in coarse grains such as oats, nuts, lean pork and animal internal organs. Foods rich in vitamin B2 include animal liver, egg yolk, dairy products, spinach, leeks, canola, broccoli, and the like. Foods rich in niacin include whole wheat products, brown rice, beans, sesame seeds, peanuts, mushrooms, chicken, lean meat, fish, and green leafy vegetables.
Iron, representing food: lean meat, egg yolk. American scientists have tested the cold resistance of women in swimwear and found that most women who are afraid of cold have insufficient iron in their bodies, and once iron is added, the symptoms are greatly improved. Iron participates in heme synthesis in the body, which can improve the oxygen carrying capacity of blood. The oxygen supply in the peripheral tissues of iron deficiency is reduced, while the lack of oxygen leads to obstacles in the energy metabolism of the body, and naturally it is cold due to insufficient heat production. Iron-rich foods include animal livers and blood tofu.
Calcium, representing food: milk, green leafy vegetables. In winter, the sunshine time is short, which is easy to cause calcium deficiency in the human body, and calcium ions help to regulate muscle contraction and relaxation. Calcium-rich foods include soy products and nuts.
Iodine, representing food: kelp, seaweed. Iodine is an important raw material for the synthesis of thyroxine. Thyroxine promotes the conversion of proteins, carbohydrates and fats in the body into energy and protects against cold. If iodine is deficient, the raw material for the synthesis of thyroxine is lacking, and the ability to keep warm is reduced. Foods rich in iodine include sea bream and shellfish.
