If you've ever seen a photo of a child who has turned orange from eating too many carrots, then you'll know that what's in our blood can sometimes show on our skin.
Vegetarians and those that love their greens tend to have an orange-ish hue to their complexion, but id someone notices that you are looking a bit yellow around the gills then visit your doctor.
When the liver isn't working to full capacity, a banana-coloured substance called bilirubin accumulates in the blood, which shows up in the skin. It also makes the whites of your eyes look a bit golden!
