Hy guys, this thread is aimed at the highly knowledgeable guys of the forum with great experience on nutrition!

Basically when I began my mission to obtain lean muscle mass and fell in love with bodybuilding I knew very little about nutrition and was in my early teens and had no idea what to eat for gains.

After reading a little and gaining a certain amount of basic knowledge I realised i needed to take in high amounts of protein and began to drink tonnes and tonnes of raw eggs blended with milk, and soon made gains.

All the years later and after numerous trainees informing me that raw eggs cannot be absorbed nd digested I still believ that the raw eggs worked and so do some experienced old skool BBers I have spoke to, but have also been informed by lots of people that the body just cannot absorb them!

So I am wondering if any of you guys on the forum could give some theory behind either answer, wether it be I am wrong or other believe raw eggs can be used?

Cheers guys.

Doesn't seem such a good idea.

"Protein Absorption & Eggs

Some older athletic diets use to propose eating just raw eggs. This is a foolish attempt at taking in additional protein. Eating raw eggs (or raw egg whites) will only result in about 50% absorption of the available protein. That means that if you eat enough raw eggs to give you 40 grams of protein, your body will only absorb 20 grams.

Eating just raw egg whites results in the same (or worse). Egg whites have a huge amount of a substance called "avidin," which loves biotin. As a matter of fact, once the avidin-biotin forms a bond, the body can't break it apart. So you will develop a partial or full Biotin Deficiency Syndrome. Cooking your eggs (or egg whites) will quickly denature the protein avidin and will allow you to absorb 98% of the protein. In short, always cook your eggs.

9. The effects of actithiazic acid on egg white-induced biotin deficiency and upon the microbial formation of biotin vitamers in the rat. DHYSE FG, HERTZ R. Arch Biochem Biophys. 1958 Mar;74(1): 7-16."

Thanks alot cyberheater, obviously id been warned off the idea by people but nobody ever gave me a theoretical explanation to back their idea up.

Hang on mate. There seems to be a big debate on exactly how many raw eggs you need to consume before the "avidin" becomes a issue.

Hopefully, someone more knowledgeable then I can clear this up.

Yah but.
Vince Gironda gave his guys raw organic eggs and beef liver tabs and his suggestion was that his guys made steroid like gains.

Arnold was another guy that ate raw eggs.

Id say if you made gains from them, then keep doing it. I would not stop eating the eggs due to bioavailable protein, I would stop them from the chance of salmanila(sp). If you wash the outside of the egg before you crack it, the chance of this is less.
I have never heard of anyone I knew getting that anyway.

Eggs have the highest bio-avalible protein of any food source, i doubt you only digest 50% of the protein, that does not seem right to me.
Again, vince gave his guys 30 raw eggs and a bunch of dessicated liver, he swore they made steroid like gains.

Yes , I can believe it. I have eatn over 4o raw eggs a day before, and have never had food poisining from them, I have also heard of loads of people who staple them in there diet, including Hulk Hogan and Arnie.

Hi mate,

Check out this thread - http://www.uk-muscle.co.uk/food-diet...gs-ok-not.html

Within this particular thread there is also 2 other links to old similar posts - it's a massive subject on here, mate.

AH24 talks a lot of sense on the thread I linked for you.

But maybe the science wasn't available to them.

Here is another study that points to the fact that you only absorb 50% of protein of raw eggs.

http://jn.nutrition.org/cgi/content/full/128/10/1716

"The true ileal digestibility of cooked and raw egg protein amounted to 90.9 ± 0.8 and 51.3 ± 9.8%, respectively. A significant negative correlation (r = 0.92, P < 0.001) was found between the 13C-recovery in breath and the recovery of exogenous N in the ileal effluents. In summary, using the 15N-dilution technique we demonstrated that the assimilation of cooked egg protein is efficient, albeit incomplete, and that the true ileal digestibility of egg protein is significantly enhanced by heat-pretreatment. A simple 13C-breath test technique furthermore proved to be a suitable alternative for the evaluation of the true ileal digestibility of egg protein."


Another study points to 95% absorption for cooked eggs vs 65% for raw using a different measurement technique.

"Ten healthy volunteers were studied once after ingestion of a cooked test meal, consisting of 25 g of 13C-, 15N-, and 2H-labeled egg protein, and once after ingestion of the same but raw meal. Amounts of 5.73% and 35.10% (P < 0.005) of cooked and raw test meal, respectively, "

That will be me then.

Raw eggs are awesome, do not give a $hit what any science says, try it and see for yourself, if they are not absorbed then they give an awesome placebo effect.

Man that took some time to read......WOW, my brain hurts....lol
I am just going to toss some things out there.

In nature all animals that eat eggs eat them raw.

I notice that a cooked egg empties the stomach slower but ends up going through the small intestines faster.
They suggested that this had nothing to do with the absorption.

Would the fact that this study was done using 4 women and 1 man change anything if it was just men?

This test was done without the yolks?
Would the addition of the yolks change this absorption % of assimilation?
Or would the fat in the egg slow down absorption in the stomach and make assimilation higher?

If one were to eat raw eggs on a regular basis would the body adapt with an enzyme making digesting and assimilation higher?

I think this would put me off from raw: Incomplete assimilation of dietary protein may have important consequences not only from a nutritional point of view, but also from a gastrointestinal point of view. Indeed, some metabolites resulting from bacterial fermentation of malabsorbed proteins in the colon have been implicated in the ethiopathogenesis of diseases such as colonic cancer and ulcerative colitis (Macfarlane and Cummings 1991 , Pitcher and Cummings 1994, Visek 1978 ).

Tried them raw. Gave me one heck of a stomach ache and some bad stuff coming out the other end. That was not a good two days. Never got anything tested, but I wouldn't be surprised if I had salmonella poisoning. Never doing that again...

cyberheater

hackskii. I agree around the issues associated with the consequences from eating raw eggs from a "gastrointestinal point of view".

It should be noted that the type of animals that would eat raw eggs in the wild would normally have a rather shorter digestive/colonic tract. In humans, this is typically much longer which is why this is an issue for us.

Only cooked eggs for me from now on.

Well, it does make sense.
But at which point would the raw be needed to be cooked to offer the best bang for the buck?

I have heard that you can nuke the egg short term and kill the enzyme.
It would still be raw in essence but also cooked to be more assimilable?

Love the thread, great thought provoking thread.

Would one get more benefits if one were to add some digestive enzymes to the raw eggs?
Hmmmm

I have always heard that raw eggs were anabolic. I just want to get my head around this.

I mainly eat cooked eggs, however, i often add 1-3 whole omega eggs into my shakes and it never upsets my stomach or any thing.
