Hi Doria,
This is a very common misunderstanding that comes from feeding parts of foods. So, while the egg white may rob biotin, guess what's got lots of biotin in it? The yolk! And, as you can guess, I'm not advocating feeding one without the other. Now, I'm guessing here, but I'd bet wolves wouldn't separate the yolk and toss it, right ;-) ?
Whole, natural foods win. Fractionating is just man's idea, and we put ourselves and our animals in jeopardy the more we think that way.
Thanks for airing this out. More people need to know this.
