What about avidin and biotin depletion? Is this a myth or what??? So many mixed messages.No one is sure. There were isolated reports of people dying if they just ate only egg-whites for long periods. There seems to be enough biotin in the yolk, though, for there to be no problems eating raw eggs. Fertilised raw eggs also have much lower avidin levels than the unfertilised kind.
Thanks Tyler. Do you know what signs/symptoms would tip off a self-experimenter? I could use these cues(if they exist) in my experimentations...http://en.wikipedia.org/wiki/Biotin_deficiency (http://en.wikipedia.org/wiki/Biotin_deficiency)
