For a while, I especially liked to pick up a carrot and eat it in the morning. Some friends gave me a cute nickname “rabbitâ€. I often listen to them and say, “How can you be a dietitian? What kind of nutrition is there for you to eat raw carrots? It's the most nutritious to fry with oil! Then is it important to eat it? Is there any nutritious food?
Everyone knows that the most nutrient-rich substance in carrots is carotene, which is a fat-soluble vitamin that needs absorption and fat to form fat microspheres to be absorbed by the small intestine.
According to Fan Zhihong’s blog, “The highest loss of carotenoids in food is fueled by high-temperature cooking. On the one hand, the bioavailability of carotene is reduced. On the other hand, a lot of fat cooking will cause carotene to dissolve into fat. The fats and oils containing these carotenoids are attached to the kitchen utensils and utensils and cause losses.†Therefore, high-temperature cooking causes a large loss of carotene.
Why do you think raw food is also possible? Related research shows that as long as the intake of foods containing fat after a period of intake of carotenoids, it can promote the absorption of carotenoids, because the carotenoids stuck on the small intestine mucosa can be with the new Incoming fat bound to form fat microspheres is absorbed.
Therefore, carrots do not have to be fried. How to make the absorption of carrots achieve the best results, it is only necessary to eat foods containing oils in the same meal or to eat foods containing oils within a certain period of time, which are helpful for the absorption of carotene.
