In nature all animals eat living foods as yielded up by nature. Only humans cook their foods and only humans suffer widespread sicknesses and ailments. Only humans regularly and consistently suffer premature death. Natural death in humans is so rare that it isn't even listed as a cause of death in our almanacs or statistics. Everybody does it.
Cooking is a process of food destruction from the moment heat is applied to the foodstuff.
Long before dry ashes result, food values are totally destroyed. Proteins begin coagulating and delaminating, as may be plainly seen in the case of eggs and cheese when their temperature reaches only 118 degrees. At temperatures commonly applied in cooking, they are completely devoid of nutritive values. Cooked proteins are readily putrefied by bacteria in the digestive tract and give rise to some very potent poisons such as ptomaine's, leukomaines, mercaptans, indoles, skatoles, ammonias, hydrogen sulfide, putrescine, cadaverine and yet more. These are absorbed into the portal blood and cause myriad's of disease conditions.
