If you ate too many carrots you would turn orange.
this is true.
this phenomenon is called hypercarotenemia and the orange tint
(sometimes yellow or yellow-orange) shows up mostly in the palms of
the hands.
this happens when a person eat too much carrots and the body does
not use all of the beta-carotene from the carrots, hence the skin
turns orange.
but the skin discoloration is harmless.
just stop eating so much carrots, and the skin will return to its
original colour.
