Carrots are rich in carotenoids, but they exist in the cells of carrots and are wrapped in dietary fiber, which is not easily digested and absorbed by the body, so if they are not chewed properly it will make it difficult for the carotenoids to be digested, thus affecting absorption. Moreover, carotene is a precursor of vitamin A, which can be converted into vitamin A in the body, and is also fat-soluble with vitamin A. Therefore, it is recommended to stir-fry or stew carrots before eating them, or cook them with meat with high fat content, such as ribs and brisket, which can increase the absorption rate of carotene. Carotene has more benefits for the human body, such as preventing and improving night blindness, dry conjunctiva, dry skin and other uncomfortable symptoms caused by vitamin A deficiency. Vitamin A is a vitamin that cannot be synthesized by the human body and needs to be obtained from food. Therefore, carotenoid-rich foods such as carrots, tomatoes, pumpkins, papayas and oranges can be added to the daily diet in appropriate amounts. In addition, in addition to the cooking method, the absorption of carotene is also related to the bile synthesized and secreted by the liver and the pancreatic enzymes secreted by the pancreas, so liver and biliary diseases and pancreatic diseases can also lead to a decrease in the absorption rate of carotene. If symptoms of vitamin A deficiency appear, you need to seek medical attention in time to determine the cause and treatment with the help of a doctor.
