Among meats, dog meat, lamb, beef, venison, donkey meat, rooster, duck, quail, crucian carp, turtle, octopus, and grass carp have the best warming effects. They have the effects of benefiting the kidneys and strengthening yang, warming the middle and lower jiao, and replenishing qi and generating blood. II. Root and Stem Vegetables
Root and stem vegetables such as carrots, sweet potatoes, green vegetables, Chinese cabbage, lotus root, cauliflower, green onions, and potatoes contain a large amount of minerals. They can be mixed with warming meats for consumption. [Chinese Cuisine] III. Iron-Rich Foods
Elderly people with iron-deficiency anemia are prone to feeling cold, so they should consume more iron-rich foods, such as animal blood, egg yolks, pork liver, beef kidney, sheep tongue, soybeans, sesame seeds, dried bean curd, and black fungus. IV. Iodine-Rich Foods
The human thyroid gland secretes a hormone called thyroxine, which has a thermogenic effect, and thyroxine is composed of iodine and tyrosine. Tyrosine can be "produced" by the body, but iodine needs to be supplemented from external sources. Foods rich in iodine include kelp, seaweed, shellfish, oysters, sardines, spinach, and fish and shrimp, which are good choices for consumption.
