The Hazards of a Health Fetish Part 3: Conclusion with Word games

In part one of this series I introduced you to a man you constantly hear about when the discussion is about raw food. Dr. Francis M. Pottenger, Jr., MD was an original thinker and keen observer whose imagination, integrity and common sense gave him the courage to question official dogma. Dedicated to the cause of preventing chronic illness, he made significant contributions to the understanding of the role of nutrition in maintaining good health.
In his
classical experiments in cat feeding, more than 900 cats were studied over 10 years. Dr. Pottenger found that only diets containing raw milk and raw meat produced optimal health, processed diets accomplished the opposite. We realized that one has to very carefully read Pottenger’s notes as some appear to be deceptive to some degree. Today I want to share with you what. Ron Schmid, ND, author of “Francis M. Pottenger, MD and "The Hazards of a Health Fetish" has to say about the doctor’s “Word games:
We see that Pottenger's own words describe clearly the superior value of raw versus pasteurized milk for the animals. Yet the "Health Fetish" authors’ statement that "a diet of one-third raw meat and two-thirds milk (pasteurized or not) did not provide adequate nutrition for the cats" is strictly speaking true, because of the use of the phrase "pasteurized or not." One experiment used raw metabolized vitamin D milk, and, like the pasteurized, evaporated, and sweetened condensed milks, this resulted in diseased animals. The metabolized vitamin D (a synthetic form of the vitamin present in the milk because the cows had been fed irradiated yeast) proved to be so toxic that it overrode the benefits of the otherwise optimal all-raw diet that were proven in the animals fed plain raw milk. Thus one type of milk that was not pasteurized had indeed not provided adequate nutrition. Had the "Health Fetish" authors used the phrase "pasteurized or raw," the statement would have been false, because the word raw would be referring to both raw milks tested—the raw metabolized vitamin D milk that did not provide adequate nutrition, and the plain raw milk that did. The choice of the word "not" makes the distortion possible without actually making a false statement. Very clever indeed. There is no discussion on the toxicity of the synthetic vitamin D in the "Health Fetish" article, and no mention of the sparkling health seen in generation after generation of cats fed raw meat and raw milk free of synthetic vitamin D.
The "Health Fetish" authors make one other statement that may not be called an untruth, yet is obviously designed to lead one to false conclusions: "Raw milk advocates have erroneously cited this article as having reported that disease occurred in cats fed pasteurized milk." I'll repeat what Pottenger reported: "The cats fed pasteurized milk as their principal item of diet, and raw meat as a partial diet, showed lessened reproductive efficiency in the females, and some skeletal changes, while the kittens presented deficiencies in development." Pottenger indeed does not actually use the word "disease" here or anywhere else in this article in reference to animals fed pasteurized milk (the article is about effects on the dental and facial structures of the animals). Yet his finding of the superiority of raw versus pasteurized milk is clearly presented. In fact, in one experiment described briefly, 13 cats fed pasteurized milk all died within several months.
The "Health Fetish" authors make no mention of a number of other relevant findings published in the Pottenger article. For example, an autopsy photograph shows the internal organs of a cat that had been fed a diet of one-third raw meat and two-thirds pasteurized milk for eight months before being sacrificed. The caption reads, "Note poor tone of skin and inferior quality of fur. Fair heart. Slight fatty atrophy of the liver. Lack of intestinal tone: moderated distension of uterus. Note the disturbance of the skin with a shift from the creamy color of the raw-milk fed cat to the purplish discoloration of congestion."
In contrast, another photograph shows the internal organs of a cat fed a diet of one-third raw meat and two-thirds raw milk all of its life. The caption reads, "Note excellent condition of fur and creamy yellow subcutaneous tissue with high vascularity. Moderate heart size. Good liver, firm intestines, and resting uterus. Note the muscle of the raw-milk-fed animal has a deeper red color and appears more vascular than that of the animals receiving the heat-processed milks."
Another experiment began with 13 cats in excellent health that had been raised on raw meat and raw milk. A table is used to show how long these cats lived after being placed on a diet of one-third raw meat and two-thirds pasteurized milk. The average length of life for the males is 4 months 11 days, for the females 3 months 27 days. The calcium-to-phosphorous ratio of each cat's femur (thighbone) is shown, and all are abnormal.
Two X-ray photographs depict the results of another experiment that used two rats, one fed raw milk (rat A) and the other pasteurized (rat B). The caption for the raw milk animal reads, "Note advanced maturity, greater diameter and length of the olecranon process [part of the elbow] of the ulna [the long bone in the foreleg]." The caption for the pasteurized milk animal reads, "Note smaller olecranon process and delayed maturity when compared with rat A."
Another photograph shows a number of bones from one of the cats, previously healthy, that died four months after being placed on the one-third raw meat and two-thirds pasteurized milk diet. The caption reads, "Note missing teeth, chalky appearance of bone, squaring of the bases of teeth and marked root resorption. Osteoporosis. Lack of completion of orbital arches [the orbit is the eye socket]. The cheek bones have become separated at suture lines [where the bones come together]."
An X-ray of the jaw of a living cat fed the raw meat-raw milk diet all of its life is presented. The caption reads, "Normal jaw structure, good distribution of trabeculae [part of the bony structure], well developed condyle [a knob at the end of the bone], and well developed pterygoid process [a little outgrowth of bone] of the mandible [jaw bone]. Alveolar crest [the alveolus is the bony socket for the root of a tooth] of normal height; even distribution of teeth."

My object here is not to give a lesson in anatomy, but rather to make accessible to the reader some of the details of Pottenger's findings. In this article he focused primarily on the effects of heat-processed foods, including pasteurized milk, on the bones and jaws of his experimental animals because the article was written for a dental journal. In many other articles published over the course of some fifteen years, he emphasizes the diseases that result in cats and other animals when fed diets that include pasteurized milk.
Another of the "Health Fetish" authors' statements quoted earlier deserves further inquiry: "Numerous studies of the relative nutritional merits of raw and pasteurized milk have been conducted in animals and humans, and no differences were detectable." This appears to be a simple statement of fact. Since, in reality, numerous studies of the relative nutritional merits of raw and pasteurized milk conducted on animals and humans have shown clearly the nutritional superiority of raw milk, one is tempted to declare the "Health Fetish" statement to be untrue. But in fact it is a true statement! Now how can that be? To answer this question, we must do a little exercise in logic.
Examine these two statements: 1) "Numerous studies of the relative nutritional merits of raw and pasteurized milk have been conducted in animals and humans, and no differences were detectable." 2) "Numerous studies of the relative nutritional merits of raw and pasteurized milk have been conducted in animals and humans, and vast differences were detectable."
It appears that if one statement is true, the other must be false, right? Wrong! Both statements may be true—it all depends on which "numerous studies" the writer is referring to, and when he doesn't tell us, he isn't pinned down. Even if the writer is aware of numerous studies that favor both sides of the argument, statements 1 and 2 may both be defended as true statements (in a court of law, for example, or in a subsequent article). Understanding this element of logic is necessary when writers employ logical tricks. Young people who go on to medical school usually study logic as undergraduates.
Notice that although the authors refer to Pottenger's animal study in the very next sentence, they carefully do not say it is one of the "numerous studies" to which they have just referred. We get the impression that it is, of course. But they do not say this, for to do so would be false; as we have seen, Pottenger's study undeniably shows the nutritional superiority of raw milk as compared to pasteurized.
But it is almost as though someone played a game of perverse (dare I say fetishistic) logic, devising technically true statements which would disguise Pottenger's findings, distort the meaning of his words and trick the reader into false conclusions. I've studied Pottenger's work for over twenty years, and it took me hours to untangle the web I've described.
It is indeed a fact that a number of researchers supported by grants from the dairy industry have published research that claimed to find no significant differences in the relative nutritional merits of raw and pasteurized milk. We have good reason to question the validity of research funded by corporate money or conducted by individuals funded by corporations. No references are given for the "numerous studies" mentioned above, so it is not possible to examine them.
The "Health Fetish" authors carefully avoided any simple, straightforward statement to the effect of, "None of the reasonable studies in animals or humans of which we are aware have shown that there is a significant difference in the relative nutritional merits of raw and pasteurized milk." They also avoided words to the effect of "The Pottenger study under discussion showed no significant difference in the relative nutritional merits of raw and pasteurized milk." Either statement would have been patently false, because scores of reasonable studies, obviously including this Pottenger study, demonstrate the nutritional superiority of raw versus pasteurized milk.
We've seen that the "Health Fetish" authors used technically (logically) true statements to completely distort Dr. Pottenger's findings. Only careful study of Pottenger's article would allow the choice of precisely the right words to accomplish this while avoiding making false statements. We may hope that the authors gained considerable understanding of Pottenger's work and its implications for the health of people everywhere. Perhaps they may someday use that knowledge in the way Dr. Pottenger intended.
Pottenger concludes his article with possible explanations for his findings, referencing his words to physiology textbooks and articles by other scientists: "What vital elements were destroyed in the heat processing of the foods fed the cats? The precise factors are not known. Ordinary cooking precipitates proteins, rendering them less easily digested. All tissue enzymes are heat labile and would be materially reduced or destroyed. Vitamin C and some members of the B complex are injured by the process of cooking. Minerals are rendered less soluble by altering their physiochemical state. It is possible that the alteration of the physicochemical state of the foods may be all that is necessary to render them imperfect foods for the maintenance of health. It is our impression that the denaturing of proteins by heat is one factor responsible. The principles of growth and development are easily altered by heat and oxidation, which kill living cells at every stage of the life process, from the soil through the plant, and through the animal."
Dr. Pottenger's work leaves us with clear indications that there is no better food for human beings than raw milk from grass-fed animals. The clear and present danger is that "experts" such as the health fetish article authors wield unjustified influence with physicians and public health authorities—influence based in large part on false representations. Understanding the truth about Pottenger's work and the value of raw milk is an important step in regaining our health.”
All I have to add is: Not just an important step in regaining “our” health, but also the health of our companion animals.

Plus: Aren’t we pet owners used to the common problem that words, especially (but not only) if used for marketing purposes can have many different meanings and often require us to think twice of what they really say? Leaving a word out here or there or using a word it in a little different, deceptive way can make a world of a difference in understanding what we are looking at and possibly going to buy.
