The answer is quite simple - too much Betacarotene. It's the stuff they feed to flamingos kept in zoos to keep their pink colouration which they get from their normal diet when in the wild.

That may be so, but as a British Citizen payment would be required for any treatment whereas it would be completely free of charge in the UK. I know I sometimes moan about the NHS [usually about the way it treats its staff] but it really IS the best in the world. Where else could you get the best treatment free?
