What should the elderly eat if they are afraid of the cold in winter?

　　The elderly should take more iron supplements in winter. Iron participates in the synthesis of iron-containing hemoglobin in the human body and improves the oxygen-carrying capacity of the blood. Therefore, iron-deficient people will have reduced oxygen supply to peripheral tissues, and the energy metabolism of human tissues will be hindered. Naturally, they will feel cold due to insufficient heat production. Therefore, the elderly should pay attention to supplementing iron-rich foods, such as lean meat, fish, animal liver, egg yolks, beans, celery, mushrooms, black fungus, etc. However, animal liver and egg yolk have high cholesterol, so you should not eat too much. You can only eat them once a week. Fried celery, sliced ​​mushrooms, cold fungus, etc. can often appear on the dinner table. While supplementing iron-containing foods, you should also eat more foods rich in vitamin C to facilitate the body's absorption of iron.

　　Secondly, the elderly can eat more iodine-containing foods in winter. elderly Hypothyroidism can cause poor local and systemic blood circulation, especially peripheral blood circulation disorders, resulting in cold hands and feet. Iodine helps the synthesis of thyroxine in the body, improves the body's basal metabolism, thereby producing a thermal effect and reducing symptoms of cold sensitivity. Foods containing iodine include: kelp, seaweed, shellfish, oysters, sardines, spinach, fish and shrimp, etc. You can choose to eat more in autumn and winter.
