What is the best winter health diet for the elderly?

　　1. Eat more staple food, including some mutton, quail and sea cucumber.

　　Protein, fat, and carbohydrates are known as thermogenic nutrients. Therefore, in winter we should appropriately increase the intake of staple foods and fats to ensure the supply of high-quality protein. Dog meat, mutton, beef, chicken, venison, shrimp, pigeon, quail, sea cucumber and other foods are rich in protein and fat and produce a lot of heat. Traditional Chinese medicine believes that they are beneficial to the kidneys and yang, warm the middle and lower parts, replenish qi and generate blood, and have the best effect on keeping out the cold.

　　Being afraid of cold is related to lack of calcium and iron.

　　2. People's fear of cold is related to the body's lower intake of certain minerals. For example, the amount of calcium in the human body can directly affect the elasticity and excitability of the myocardium, blood vessels and muscles.； Iron deficiency in the blood causes iron deficiency anemia The important reasons are often manifested as low heat production and low body temperature.

　　Therefore, supplementing foods rich in calcium and iron can improve the body's ability to resist cold. Foods containing calcium mainly include milk, soy products, kelp, seaweed, shells, oysters, sardines, shrimp, etc. ； Iron-containing foods are mainly animal blood, egg yolks, pork liver, soybeans, sesame seeds, black fungus and red dates.

　　3. Kelp and seaweed can promote the secretion of thyroid hormone and produce heat.

　　One of the human body's thyroid secretions is called thyroxine, which can accelerate the oxidation of many tissue cells in the body, increase the body's heat production capacity, and enhance the basal metabolic rate. skin Blood circulation is accelerated, cold resistance is maintained, and iodine-containing foods can promote thyroid hormone secretion. Foods rich in iodine are: kelp, seaweed, nostoc, jellyfish, spinach, Chinese cabbage, corn, etc.
