Eating an orange every day will turn your face yellow.

That’s because these yellow foods are rich in carotene. It happens that the body of the eater lacks the specific enzyme to digest and decompose carotene. The carotene intake is too high in a short period of time, and the body’s conversion efficiency of vitamin A is also high. If it is low, carotene cannot be converted into vitamin A in time; a large amount of carotene will flow with the blood to various tissues and organs throughout the body. When the carotene content in the patient's blood and sweat increases, normal skin will appear yellow.

After eating a lot of oranges, pumpkins, persimmons, carrots, oranges, etc. in a short period of time, I find that my skin turns yellow. Even if I stop eating these foods, it often takes a few days to fade away. .

Extended information:

This type of skin yellowing caused by consuming a large amount of carotene in a short period of time is clinically called "orange syndrome", also called hypercaroteneemia. Symptoms are most common in children and young women. There is a clear difference between "orange syndrome" and the yellowing symptoms of icteric hepatitis: although the skin is yellow, the sclera (the white part around the periphery of the eyeball) of patients with "orange syndrome" is not yellow, the urine and stool are normal, and the skin is yellow. Most of them are on the face, nose, mouth, hands, etc., without other symptoms.

Don’t worry too much if you have orange syndrome. As long as you stop eating high-carotene foods, they will usually be metabolized in a few days and are harmless to your health. Although it is harmless to the body, we do not encourage everyone to eat a large amount of a single fruit in a short period of time. It is still necessary to enrich the variety to make the nutrition more balanced.
