In the cold season, people who are afraid of cold are often weak due to yang deficiency, often with tepid limbs, pale and emaciated face, loss of appetite, shortness of breath and fatigue. These people generally have chronic diseases or lack of physical exercise at ordinary times, and the quality and quantity of diet nutrition are insufficient. Therefore, in addition to strengthening physical exercise and treating its existing diseases, improving diet and nutrition is a very important aspect. Here are some foods that are beneficial to people with deficiency cold and yang deficiency in cold season for you to choose.

Hot food

Chinese medicine believes that mutton, dog meat, longan, leek, walnut, millet and other foods have the function of warming yang and benefiting qi, and eating more in moderation can improve the ability to keep out the cold. On the contrary, it is best to eat less cold or cold food such as duck, crab, banana, cucumber, pear, mung bean, watermelon and rock sugar.

Food containing methionine

Low temperature increases the excretion of creatine in human urine and accelerates fat metabolism. Both creatine synthesis and fat metabolism need methyl, and methionine can provide methyl. Methionine is one of the eight essential amino acids for human body. Foods rich in amino acids include sesame, sunflower seeds and leafy vegetables. For the elderly, it is better to eat more pig blood. The proportion of amino acids in pig blood is very close to that of human body, which is easy to be absorbed and suitable for the elderly with decreased digestive function.

Calcium food

Medical research has proved that fear of cold is related to mineral deficiency in diet, especially calcium deficiency, which will affect the flexibility and excitability of myocardium, blood vessels and muscles. Therefore, it is advisable to eat more calcium-rich foods such as milk, bean products and shrimp skin in winter. In addition, carrots, sweet potatoes, lotus roots, green onions, potatoes and other root vegetables contain a lot of minerals, and regular consumption can also enhance the cold resistance of the human body.

Foods containing vitamins

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 cold tolerance of human body; Vitamin C can improve the adaptability of human body to cold. Therefore, the intake of foods rich in vitamin A such as animal liver, carrots and pumpkins and foods rich in vitamin C such as fresh vegetables and fruits should be appropriately increased in winter.

Iodine containing food

The human thyroid gland can secrete a hormone called thyroxine, which can produce heat. Thyroxine is composed of iodine and tyrosine, which can be synthesized in vivo, but iodine must rely on "foreign aid". Therefore, we should eat more iodine-rich foods such as kelp, laver and shellfish in winter.

Iron food

Studies have shown that many women's fear of cold in winter is related to iron deficiency in their bodies. Therefore, women who are afraid of cold can eat more iron-rich foods, such as animal blood and liver. Iron in animal food is heme iron, which has a high absorption rate after being ingested by human body, especially in animal blood, and its iron absorption rate can be as high as more than 22. Plant food, such as auricularia auricula, kelp, sesame, etc. Although the iron content is high, the absorption rate is low, mostly around 10.
