Protein value of raw and cooked eggs?

[Huike]

Any difference? Or is one easier than the other for the body to uptake?

[CharliC]

The protein in cooked eggs is more bioavailable.

just finished reading the study. really great!

any basic cooking class explains you burn nutrients proteins etc as you expose a food to heat, a raw egg will have more more protein compared to a cooked egg because it hasnt had its protein burnt away in the process of cooking, as far as digestibility goes, not everything can be broke down to b/s science for some overcomplicated answer, obviously raw eggs are a better source for your protein, even over those stupid protein shakes n supplements b/c it is natural unlike that powder bs, just an opinion, but naturaly organic is better then man made everytime

You don't burn up macronutrients in the cooking process. If that was true, then the fats of the egg would also "burn up" because that is a macronutrient as well. You really should not be giving advice like this.

Edit: Heat causes protein to denature, not burn up. This does not render the protein completely useless.

I always thought that less cooked foods would keep more protein intact. Good thing I like my steak rare

This is true for the most part, but the thing is that is different between steak and eggs is the bioavailability of the macronutrients.

Same idea that even though your body doesn't process 100% of the protein (cooked or not), you're still supposed to count all the calories that the egg represents.

But again, steak has many different lengths that it can be cooked (rare, medium, etc) until it becomes charred carbon. Eggs on the other hand...

if any difference it is very very small. just eat it cooked imo. tastes better & is safer

small difference? Not really, if we are talking about bioavailability.

Here is a relevant excerpt from the study posted by in10city:

"The calculated true ileal digestibility of cooked egg protein amounted to 91%. This finding demonstrates that even cooked egg protein, which has generally been considered to be easily digestible, is malabsorbed to some extent after ingestion of a physiologic load...In this study, it was shown that after ingestion of 25 g of raw egg protein, almost 50% is malabsorbed over 24 h. The higher digestibility of cooked egg protein presumably results from structural changes in the protein molecule induced by heating, thereby enabling the digestive enzymes to gain broader access to the peptide bonds."

you really should finish reading something before putting your two cents in, clearly stated it was an opinion, a raw egg contains more protein then a cooked egg regardless, youd have to be a fool to believe you can burn something and expect it to be exactly the same, cooking something changes the substance of its original form, doesn't take a genius to understand that concept, there are all kinds of books that say something with an opinionated, compare the results from eating cooked eggs and raw eggs in a trial period and you will see the difference, again, educated opinion, not everything needs to be overcomplicated, trial n error will show you, again OPINION, think for yourself once n awhile n find out your own answers
