Can you turn orange from eating too many carrots?
Yep. That beta-carotene can pigment your skin just like it does your carrot cake.
How many carrots would I need to eat?
Partially depends on how bioavailable the carrots are.
As in, are you eating them raw? (more carrots needed)
juiced? (fewer carrots needed).
Also, since beta-carotene, aka vitamin A, is fat-soluble, the less body fat you have the more likely you are to store this orange-molecule in your skin.
