Could Carrots Be The Secret To A Long Life And Sex Appeal? ScienceDaily 5/11/07 "...The work was carried out on sticklebacks, and compared the fate of fish that all received the same basic diet but had different amounts of carotenoid supplement. Male sticklebacks need carotenoids to produce the red throat patch that they develop in the breeding season and display to females...Dr Thomas Pike, researcher in Environmental and Evolutionary Biology at Glasgow University said: 'Males provided with fewer carotenoids still tried to produce a bright red throat patch, but could only do so by diverting carotenoids away from their role as antioxidants; so by trying to look as good as possible, these males aged faster.' ...'The positive effects of a carotenoid-rich diet are likely to apply to many other animal species as well – but whether eating carrots makes humans longer-lived and more handsome remains to be seen!' "
I would be very surprised if carotenoids have as beneficial effect in humans as in stickleback fish that rely so heavily upon them.
