POTENTIAL REACTIONS TO INFORMATION IN THIS PAPER: PART 1
- Contrary facts vs. vegan dogma: facing the honesty problem
- Synopsis of the primary evidence (conclusions): Humans can be regarded as natural omnivores, and we are not natural vegetarians
- Veg*n diets are not the natural diet of humans
- Failure to thrive (FTT)
- Your health is more important than raw/veg*n dietary dogma
- Feelings of superiority and recitation of mantras result in blocking of contrary information
- Excuses and rationalizations the "party line" reaction to FTT
- How often are diet gurus honest and humble?
- For some diet gurus, dietary dogma is more important than the health of their followers, and victims may be blamed if the diet does not work
- Difficulty of resolving the question with nutritional calculations done "on paper," opinions from nutritionists, or with clinical studies done to date
POTENTIAL REACTIONS TO INFORMATION IN THIS PAPER: PART 2
- Rationalizations about the evidence for omnivorous diets from the fossil record and comparative anatomy
- Diet gurus excel at spinning rationalizations.
- Rationalization: The fossil record is irrelevant because we were created, rather than evolved--evolution is nonsense!
- Rationalization: Our prehistoric ancestors were acting "against their nature" by eating meat for 2.5 million years!
- Rationalization: The evidence of modern ape diets is irrelevant because we are a unique species, and we evolved in a different environment (the African savanna) than the forest-dwelling great apes.
- Rationalization: The human gut is far too elastic for comparative anatomy to tell us anything about our natural diet.
- Rationalization: The evidence of comparative physiology is irrelevant because: we can get B-12 from unwashed produce; low bioavailability of some nutrients from plants is good because they are toxic except in tiny quantities; physiological measurements made on meat-eaters are invalid!
- Rationalizations in response to the evolutionary and hunter-gatherer evidence for omnivorous diets
- Rationalization: What happened back in the Paleolithic age doesn't really matter. We are different people today.
- Rationalization: Evolution is concerned with reproductive success, not longevity. By the latter measure, vegetarian diets are an improvement on evolution.
- Rationalization: Hunter-gatherers may eat some meat but they are not that far from being vegetarians. Plant foods predominate, and animal food is sporadic because hunting is usually unsuccessful/inefficient compared to gathering of plant food.
- Rationalization: There are no vegan gatherer tribes because they have not been exposed to the "enlightened" philosophy of veg*nism.
- Rationalization: The hunter-gatherer diet is not feasible for people living in modern times.
