Eat more staple food, and eat some mutton, quail and sea cucumber properly. Protein, fat and carbohydrates are called thermogenic nutrients. Therefore, the intake of staple food and oil should be appropriately increased in winter 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, which generate more calories and have the best cold-proof effect.

Supplementing foods rich in calcium and iron can improve the body's ability to keep out the cold. Calcium-containing foods mainly include milk, bean products, kelp, seaweed, shells, oysters, sardines, shrimp and so on. Iron-containing foods are mainly animal blood, egg yolk, pig liver, soybeans, sesame seeds, black fungus and red dates.
