Carrots help you see better in the dark

This has some basis in truth. Deficiency in vitamin A results in a diminished ability to see in dim light. The characteristic orange pigment of carrots is a source of vitamin A, so it is possible that consumption of carrots would improve dim-light vision in people with vitamin A deficiency. However, this deficiency is rare in Australia so for most people, eating carrots is unlikely to improve vision significantly. No one can see unaided in total dark, no matter how many carrots they eat.

The consumption of very large amounts of carrots can result in the accumulation of the orange pigment and the skin appears yellow. This fades when the excessive consumption is discontinued.
