I remember early in my childhood I had some neighbors who were health nuts and they always offered me a snack carrot, then I decided carrots were really healthy and remember at least a few times eating too many carrots and I got a peculiar nauseous stomach wooziness I call “the carrot feeling.”
Yes the nausea is very real! Also people who eat too many carrots and other orange things with a lot of beta-carotene such as pumpkins, their skin actually begins to take on an orange hue.
