Adjust your winter diet wisely and add more heat-source foods. The diet should be supplemented with more thermogenic nutrients, such as carbohydrates, fats, and proteins, to improve the body's tolerance to low temperatures. In particular, you should consider supplementing with protein-rich foods, such as lean meat, chicken, duck, eggs, fish, milk, beans and their products. Supplement more foods containing methionine. Methionine can provide a series of methyl groups necessary for cold-resistant adaptation through transfer. Cold weather increases the excretion of creatine in human urine and accelerates fat metabolism. Methyl groups are required for the synthesis of creatine, fatty acids, and phospholipids, which are oxidized in the mitochondria to release heat. Therefore, you should eat more foods containing more methionine in winter, such as sesame seeds, sunflower seeds, yeast, dairy products, and leafy vegetables. Supplement appropriate amounts of inorganic salts. Medical research shows that people's fear of cold is closely related to the lack of inorganic salts in the diet. Experts suggest that you should eat more vegetables containing rhizomes in winter, such as carrots, lilies, potatoes, lotus roots, green vegetables, Chinese cabbage, etc., because the rhizomes of vegetables contain more inorganic salts. The amount of calcium in the human body can directly affect the elasticity and excitability of the human heart, blood vessels and muscles. Calcium supplementation can improve the body's resistance to cold. Foods containing more calcium include: dried shrimps, oysters, peanuts, clams, milk, etc. Eat more foods containing VB2, VA, and VC. Cold weather strengthens the body's oxidative function, and the body's vitamin metabolism also undergoes significant changes. Vitamin B2 (riboflavin) should be supplemented in the diet in time to prevent angular stomatitis, cheilitis, and glossitis. Wait for the disease to occur. Vitamin B2 mainly exists in animal liver, eggs, milk, beans and other foods. Vitamin A can enhance the body's cold tolerance. You should eat more foods rich in vitamin A, such as liver, carrots, pumpkins, and sweet potatoes. Vitamin C can improve the body's ability to adapt to cold and has a good protective effect on blood vessels. You should pay attention to the intake of fresh vegetables and fruits.
