What's so bad about pasteurised eggs?
For what it's worth, heat in general seems to increase the burden of CML-like AGEs in food, which according to recent reports is not desirable, but what else may be bad about it?
However, this only applies to food subjected to heat for prolonged periods of time, <20 sek pasteurised food is still almost-raw.
Love to cite that paper[1]:
Egg, fried 27 kU/g
Egg yolk, boiled 12 kU/g
(Chicken breast, fried 15 min 61 kU/g)

Lol i have been drinking raw egg whites in my shakes for sooo long. and now i found out i have been getting 50% of the protein out of them.
I find its easier to eat them in a shake as i cant be bothered cooking and eating the tasteless whites..
and i was thinking of putting raw pasturized eggs into my shake but now there bad aswell lol

Digestibility of cooked and raw egg protein in humans as assessed by stable isotope techniques.
Egg proteins contribute substantially to the daily nitrogen allowances in Western countries and are generally considered to be highly digestible. However, information is lacking on the true ileal digestibility of either raw or cooked egg protein. The recent availability of stable isotope-labeled egg protein allowed determination of the true ileal digestibility of egg protein by means of noninvasive tracer techniques. Five ileostomy patients were studied, once after ingestion of a test meal consisting of 25 g of cooked 13C- and 15N-labeled egg protein, and once after ingestion of the same test meal in raw form. Ileal effluents and breath samples were collected at regular intervals after consumption of the test meal and analyzed for 15N- and 13C-content, respectively. 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.Nutrition and Supp Science FAQ:

1. You are correct that applying heat to eggs denatures Some of the nutrients, but the cooking makes others become more bioavailable...
2.) the most recent evidence shows that about 94% of the protein is available from cooked eggs vs about 60% from raw. Its all a matter of preference. I prefer to drink my eggs with almond milk and whey isolate as opposed to eat them for the sake of it being quick and easy because I don't always have time to sit, cook, and shovel down an entire plate full of food.
3.) In raw eggs there is a protein called avidin that bonds to biotin and prevents it from being absorbed or at least it becomes malabsorbed. However, cooking the eggs negates that
At the end of the day man it's totally up to you. I have no digestion issues or apparent vitamin defiencies (most bodybuilders or regular gym guys get plenty of b vitamins as is). Unless youre prepping for the Olympia - do what feels right for you. Who gives a **** if anyone else doesn't like it or has something negative to say. People always will. Go raw. Go cooked. Go with whatever you like at the moment - thatll probably change 6 months from now anyway!Team GAT Representative
