Pottenger's cats - One particular question that Pottenger addressed in his study has to do with the nutritive value of heat-labile elements—nutrients destroyed by heat and available only in raw foods.
A Study in Nutrition - As for as applying his results to human nutrition, Dr. Pottenger said, "While no attempt will be made to correlate the changes in the animals studied with malformations found in humans, the similarity is so obvious that parallel pictures will suggest themselves."
Cats are not humans - Dr. Pottenger observed that cats fed a cooked diet developed a number of pathologies, some of which were remarkably similar to certain diseases of civilization, whereas cats eating raw didn't suffer from these problems. It has thus been tempting to blame cooking for all the food-related evils from which we suffer; and in the raw-food movement, this study has been held up as the quintessential paradigm of proof of the perils of cooked food. However, casting Pottenger's experiment in this role suffers from some weaknesses that we shall examine, some of which are fundamental.
