Carrots, which are known and much of the time used for their beta-carotene; can also be a problem for the human body. Having too much beta-carotene can be problematic for the pigment in your skin; causing it to turn to an orange or yellow shade.
This health problem is called Carotenemia and most times occurs in infants or toddlers who eat carrot purees. This issue can also occur in adults, teenagers, or children who eat way too many carrots in their diet.
