If you love carrot juice but you have noticed that you are looking more tanned that usual, perhaps you should consider Carotenemia. Carotenaemia (xanthaemia or carotenosis) is the presence in blood of the yellow pigment known as carotene. Often this occurs from excessive intake of carrots or other vegetables containing the pigment resulting in increased serum carotenoids.
Carotenemia is a common finding in children. Mostly due to the excessive intake of carrots, but it can also be associated with the ingestion of many other yellow and green vegetables and citrus fruits. Carotene is a lipochrome that normally adds yellow color to the skin. With elevated blood levels of carotene, the prominence of this yellowing is increased. This condition is completely harmless but it can be mistaken for or even mask the signs of Jaundice, a yellowing of the skin due to Liver disease.
