Theories on why some do great w/ Raw Meat?

Answered on August 19, 2014

The Primal Parent announced this week that she's done with cooked meat. What are scientific reasons for some paleos feeling better this way?(B-vitamin def/yeast overgrowth?) The general consensus on P-hacks is that cooked is easier to digest and extracts more nutrition, as well as the cooking/evolution theory. So whats the health benefit?

Ahh ok thanks Stephen. I was able to find the study, it seems legit: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3228431/

Not a study, but some commentary by anthropologist Richard Wrangham concerning the expensive tissue hypothesis (increase of hominid brain size relative to decrease of GI size). He briefly mentions the evolutionary benefits of cooked vs. raw meat.

If one wanted to test the digestibility of raw vs cooked, how could one go about doing that? fecal testing?

It's in the Scientific American blog boss. Unfortunately it's in mice not humans, if you ctrl+f what I posted you should find it, it is a little ways down.

Stephen, did you forget to link the study you were discussing under my last response? I'd like to see it.

This one is in humans, but it's cooked food, and doesn't specifically qualify meat: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897733/

In retrospect this does not seem surprising. Heat denatures proteins and makes them easier to digest. Heat also kills bacteria and might decrease the immune cost of eating meat by reducing the work the immune system has to do which allows the body to make, well, more body for a given number of calories.

The mice on the different diets got about the same amount of exercise. They all had a wheel to run on, and they did not differ one treatment to the next in terms of how inclined they were to take a jog. They did differ, however, in how much they weighed at the end of the study. As predicted, mice lost more than four grams of weight on raw sweet potatoes, but gained weight when given cooked sweet potatoes (whether or not they were pounded). But what about meat? Cooked meat was easier to digest. The mice lost 2 grams of body mass on raw meat but just 1 gram on cooked meat.

It is easier (cooked meat to digest), that's a fact, not something that can speculated, you can find studies on it on pubmed for example.

I don't actually think cooked meat is easier to digest. The benefits of cooking meat for hominids was, as I understand it, largely due to increasing palatability, reducing parasites, and the ability to keep it without spoiling.

I don't know about the health benefits, especially since in theory cooked meat is easier to digest than raw meat like you mentioned. I eat very little meat, but when I do I prefer raw meat and fish, cooked meat smells like feces and piss to me, raw meat smells good to me. I have histadelia, that's the reason for my low tolerance of cooked meat, and fish.

I suspect it has something to do with carnitine, or some other substance that can be found in raw meat but is mostly destroyed by cooking.
