I've heard a bunch of conflicting info about the benefits of drinking raw eggs.
It is attractive to me for the following reasons:
Eggs are cheap , drinking eggs is an easy protein+ fat meal, it tastes pretty good to me.
I have heard two things regarding to absorbtion.
school of though #1 drinking raw eggs is a superior way to get their protein because the proteins do not get denatured from the cooking process (e.g. fried eggs supposedly get denatured somewhat)
#2 eating cooking eggs makes their protein more absorbable by your body
I have also read some **** about albumen binding to biotin and excessive drinking of eggwhites gives you a biotin deficiency. but also egg yolks are high in biotin, so if you drink yolk+white is the biotin concern voided?
I don't have reps to give, but i think it would be awesome to see some science put this myth to bed.

thanks for the idea. is the idea with the pasteurized egg whites that the protein has been sufficiently cooked or denatured so that it is more bio-available?
I honestly have been googling and googling and can't find any scientific basis for why uncooked egg is only 51% bioavailable whereas a cooked egg is said to be 91%

Denaturing a protein is not a bad thing somehow people associate denature with destroy and that is not the case.... When you are denaturing a protein you are changing its conformational shape (or "unfolding" it) this is why a raw egg white is clear, and a cooked egg white is white (it changes the properties and appearance of the molecules). Proteins get denatured by excessive heat or acidity and they get denatured any time you eat a protein containing meal by the HCL in your stomach. In many cases (such as in this one) it increases not decreases bioavailabity.
Salmonella may be a concern with uncooked, unpasteurized eggs. So if you buy the pasteurized kind you can have them raw, I just think cooking them would be better.THE ONLY THING HOLDING YOU BACK IS YOURSELF

Digestibility of Cooked and Raw Egg Protein in Humans as Assessed by Stable Isotope Techniques
1 in 20,000 - 30,000 may contain Salmonella.
As for avidin, from what I've seen, avidin irreversibly denatures at 65-70 degrees C. Some companies say that the pasteurization temperature isn't high enough to break the bond (http://www.betterneggs.com/faq/answer.cfm?qid=17), while others claim it does (http://www.eggwhitesint.com/go/bodybuilding-protein)Last edited by in10city; 10-07-2008 at 06:00 PM.
It is the mark of an educated mind to be able to entertain a thought without accepting it.

yes, in this case cooked is much more bioavailable... It is also cited in that study which showed the bioavailability of eggs almost doubles from around 50% (raw) to a bit above 90% when cooked.
Both taken from the study posted:
"The true ileal digestibility of cooked and raw egg protein amounted to 90.9 ? 0.8 and 51.3 ? 9.8% , respectively."
"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. "Last edited by ben2285; 10-07-2008 at 09:57 PM.

Not trying to be an @$$ here man, but honestly... He linked it for you, if you are curious, the least you could do was read it.
Why would you want someone elses opinion of the facts, without reading all the facts yourself first? That is how missinformation/misinterpretation of the facts get so spread around.Caleb Donnelly

they sell some **** in the egg section in cartons that has color and flavor and bull**** added so people can make easy fake omlets "EGG BEATERS" for instance
next to that stuff will be a similar carton of ONLY plain egg whites
note that this is probably not a monetarily efficient way to get a lot of protein.

I didn't need all those studies to eventually realize cooked is better. I can only eat half as many eggs cooked as raw, so I assumed right then that there's more I'm getting out of them cooked if I'm filling up on fewer eggs.
Still though, mixing raw eggs and maple syrup into a protein shake tastes amazing!
