I know, hrdgain, I was just kidding around. But as Ross said...we've been cooking food for thousands of years and if you want to speak of evolution, the prevailing belief is that applying heat was one of the KEY things that allowed us to derive enough protein for our growing brains.

But the reason I joked about it in the first place is because I figured people would start getting up in arms and defensive about their believes. And I see that is already happening.

Applying heat to proteins "unfolds" the protein. Proteins are made up of two different kinds of bonds. Very tight covalent bonds that bind the aminos together in chains. And weaker bonds that fold the protein chains into their shape.

In a working body the shape of the protein is crucial to it's function. But as for as digestion is concerned...the aminos themselves are what is important.

Heat will not do much to damage the strong covalent bonds of the aminos. That requires the body's enzymes, acids, bacteria, etc. But heat can easily disrupt the weaker bonds and open up the protein, thus exposing more surface area to the digestive process thus making digestion more efficient.

I've also heard things about it weakening some of the coatings on proteins and whatnot but I know nothing of this.

It is NOT that well understood. This is the THEORY. All this stuff is theory.

Theory is not FACT. Theory's are not PROVEN. It is not the job of science to prove theories. It it to disprove them. Whatever theory, at present, best describes the natural state of things, is the accepted theory until a better theory comes along and shakes up that theory, taking it's place. Then that theory will stick around until something better comes along, and it too will not be FACT, but theory.

So, quite frakly, and endless philosophical argument on how we are designed would be pointless.

I don't know the ANSWER. But the above is a better explanation than "we were designed" to do this or that. To get into how evolution works would be pages and pages of discussion. But sufficeth to say, just because our ancestors somewhere way back in the prehistoric past could have subsisted on raw meat has nothing to do with whether cooking it would open up more protein. I mean, they also were scavengers and sucked out the bone marrow, ate the pickings left over my predators. So, go find some road kill.

As soon as we started becoming better hunters we seemed to have started becoming cookers.

As for myself, I've made is clear that I am speaking of meat and protein in general. If you want to eat raw meat, what do I care? If you don't want to eat raw meat..why argue about it? I don't to take steroids so I don't feel compelled to argue about how great they are. People who are interested in them can argue about them. I like to cook my meat and I feel fairly comfortable with that lifestyle choice, lol.

And I know a bunch of people are going to say they already know all tha

If you act sanctimonious I will just list out your logical fallacies until you get pissed off and spew blasphemous remarks.
