Guest guest Posted December 12, 2007 Report Share Posted December 12, 2007 I read on Mercola's website a while back that raw egg whites have a substance called avidin I think which blocks biotin. That is why, at least at the time, he recommended eating the yolks raw but cooking the whites. Seems like a lot of work to me.

Guest guest Posted December 12, 2007 Report Share Posted December 12, 2007 Thanks for the correction Bee. I'm glad they don't as that is one less thing, then, I will have to worry about.

" ) Hi Jecca. Just so you know, Dr. Mercola does change his mind about things from time to time, and I respect him for it. At least he lets us know when he has been wrong about something. However, Sally Fallon believes that egg whites have substances that block protein digestion. I haven't seen proof of that, and my friend, an Orthomolecular Physician in Australia and I agree that animals in the wild don't stop to get rid of egg whites, and obviously egg whites haven't caused them problems or they'd be sick and possibly die out. Sometimes science gets too scientific for my liking. Anyone can isolate a substance in a food and prove that it is damaging in a laboratory. But in the " real world " it isn't, and that is because it is a whole food and it all works together. I do not believe in maligning God-given foods that have been consumed for centuries and kept the human-race going. Bee Quote Link to comment Share on other sites More sharing options...

From the article I read (Newsletter 611),his recommendation is to cook the egg whites (but not the yolk) in contrast to newsletter 376 which suggested eating egg whites. I also wanted to say that since good bacteria produce biotin and since many of us that have Candida do not have good intestinal flora, I would be reluctant to eat egg whites raw. I am glad this topic has come up as I have been wondering about it for a while. I realize the discovery of biotin by feeding raw egg whites to rats was a bit problematic (I am not sure if the repeat experiemnt was done using whole eggs - that would be intersting!). Can you please clarify? Quote Link to comment Share on other sites More sharing options...

First, before I review the update, I want to dispel the common myth that raw eggs are bad for you. Most people fear them because of the risk for salmonella contamination. If you are still concerned about this please read my earlier article on raw eggs. As part of that article I had stated that one should never consume raw egg white alone without the yolks, as a component in them called avidin binds to the B-vitamin biotin, potentially creating a deficiency in your body. However, my position shifted when one consumed whole raw eggs, both the yolk and the white together. <<<<Please Note!!! One of my raw food mentors convinced me that there was more than enough biotin in raw egg yolks to compensate for this problem, and I revised my previous recommendation to say that eating whole raw eggs would not pose a problem. This idea made sense to me as many wild animals consume raw eggs with no apparent problems. However, recently a subscriber, Dr. Sharma, PhD, who is a biochemist with Bayer, contacted me about this issue. His investigation into the matter revealed that there is not enough biotin in an egg yolk to bind to all the avidin present in the raw whites. He found that 5.7 grams of biotin are required to neutralize all the avidin found in the raw whites of an average-sized egg. There are only about 25 micrograms -- or 25 millionths of a gram -- of biotin in an average egg yolk. This is obviously not nearly enough to do the job. For this very reason, controlled diets of ***only raw egg whites lead to severe biotin deficiency.**** " Bee Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 14, 2007 Report Share Posted December 14, 2007 Bee, I had also read that if a person ate raw eggs(whites) daily your biotin supply would be depleted in 5 months. I have found a few references that stated eggs blocked the absorbtion of the folate in them. I will try to relocate those articles and read them closely. > >> Bee, > > > > Can you point me to this article on Dr. Mercola's site?

My doctor initially suspected biotin deficiency and/or vit. B deficiency. Tests came back ok, duh, but I'm now scrambling daily eggs in butter. There's biotin in the raw yolks but maybe not enough to offset the raw whites. Susie Quote Link to comment Share on other sites More sharing options...

Hi Bee, I may be missing something here but it sounds like this means there WOULD be a problem with eating whole raw eggs as " there is not enough biotin in an egg yolk to bind to all the avidin present in the raw whites " . I eat 6 raw eggs a day so this is important for me to understand. By the way, does adding hot water to the raw eggs (per recipe) in the Bee drink change the structure of the raw white to slightly cooked - and if so, does that help? Thanks, Anita T.

You would need to follow this thread more closely, since I wrote a reply to the above statements. Raw eggs do not cause a biotin deficiency - do a message archive search to find out more of what was written on this subject. Bee Quote Link to comment Share on other sites More sharing options...
