I'll give my "dogmatic" (KD would call it so) stand: anything cooked is bad. 
I would rather eat cooked yams over, lets say, raw onion any day!
Also cooked egg whites over raw ones.
And cooked chicken over raw chicken...
Those are my some of my preferences where I'd choose cooked over raw, since were talking good vs. bad

...I believe, suggested that the body's digestive system is still oriented towards breaking down raw not cooked foods, so that the denaturing caused by cooking alters the proteins in such a way that they can't be so asily digested.
I think after eating a lot of cooked food many people can get used to it digestion-wise, but yes intrinsically raw foods are whats meant to digest.
I used to eat a lot of cooked meat and it took long to digest, heaviest of all the foods I ate. My digestion system was always very fast though, even with cooked meat, so when I started eating all the raw meat at first it would digest so fast it wouldn't fill me up, but after just a short while my digestion calibrated to eat mostly raw meat and digested it slower (which is good so I am not hungry after eating it).
My theory is, the stomach needed different and more powerful acids to digest all the cooked meat (which is hard to digest generally), then when I moved to raw meat I still had those super-strong acids (for digesting the cooked meat) and those acids would obliterate completely the raw meat. But very quickly my acids when back to normal so now raw meat is filling. That explain why if I ever eat a cooked meal now I feel some strong acids inside me.
