White skin is what most women pursue, and most people will know to eat more foods rich in vitamin C, such as strawberries, tomatoes, guava, kiwi fruit, cherries and other fruits and vegetables. But there are also some foods that turn black when eaten! Do you know what kind of food this is?

First: carrots and papaya contain high content of beta carotene, which will lead to yellow skin if eaten too much.

Beta carotene can be converted into vitamin A, which has a good antioxidant effect, but eating too much will make the skin yellow, so you can eat carrots and papaya, but be careful not to overdo it. For example, it is ok to stir-fry with a little carrot, but drinking a few glasses of carrot juice every day is a bit too much.

Second: Eat less beef, mutton, pork, viscera, chicken, turkey and duck.

Because these foods are rich in two kinds of amino acids: tyramine acid and amphetamine acid, which are the main nutrients to form melanin, don't eat too much, otherwise the skin will turn black if there are too many raw materials of melanin, so seafood is a safer food.

Third: remember to wash your hands after handling lemons, celery, carrots and nine-story towers.

These ingredients contain photosensitive substances. If you don't clean it and leave it on your hands, it will cause skin redness, allergies and pigmentation in the sun. Clinically, patients who squeeze lemon juice often get black hands, which is caused by squeezing lemon, not washing hands afterwards and exposure to the sun.

Is it easy for the skin to turn black after eating these foods? "Basically, it doesn't matter as long as there is sun protection during the day. Lemons are also rich in vitamin C. It's a pity not to eat them, isn't it?" There is no medical basis for judging whether the color of food affects skin color, but it is true that carrots and papaya will turn yellow if eaten too much. If you want to whiten, the color of the food you eat is not important. The most important thing is complete sun protection.
