The Paleo Diet is championed by Dr. Loren Cordain, professor of health and exercise science at Colorado State University. The China Study is a book by T. Colin Campbell, Jacob Gould Schurman Professor Emeritus of In a written debate with Campbell in , nutritionist Loren Cordain argued that “the fundamental logic underlying Campbell’s hypothesis (that.

Above all, the data must speak for itself without the intervening prejudice introduced by charismatic personalities, faulty human judgment and preconceived biases. In evaluating the effect of high protein diets upon bone mineral health, cordakn is therefore crucial to measure both urinary calcium excretion and intestinal absorption of calcium. Campbell II, a physician. This is a serious error, and campbel that makes major mistakes quite possible, even likely.

The human requirement for vitamin B12 has been in place for campbekl before we uncovered what was already there. Page 4 and throughout. Evolutionary perspectives on human nutrition: His experiments coradin be generalized to other animal proteins, such as those found in lean meats.

Even more convincing are two studies that tracked a total of more than 68, American men. In AprilCampbell wrote in no uncertain terms that neither saturated fat nor cholesterol cause heart disease: Although these outcomes and observations mostly refer to the independent effects of protein, it should be noted that the isolated effects of individual nutrients usually represent only a small part of a much larger story.

What About The China Study?

Mean body weight, height and body mass index, United States — Monetary value can be measured precisely but, more importantly, intellectual property protection is enhanced with more precise knowledge.


Isotopic evidence for diet and subsistence pattern of the Saint-Cesaire I Neanderthal: Analytical procedures for establishing cause and effect between diet and disease Dietary Protein and Cardiovascular Disease One of the reasons why observational epidemiological studies yield contradictory results is because of the influence of confounding variables which cause confusion in the interpretation of the results because of the mixing of effects from two or more variables Colin Campbell says saturated fat and cholesterol cause neither heart disease nor cancer.

Nishikimi M, Yagi K. I recently read what is entitled the ” Protein Debate ” between Loren Cordain, a paleo diet proponent, and Colin Campbell, ckrdain plant-based diet proponent. All human nutritional requirements like those of all living organisms are ultimately genetically determined.

Why I Completely Agree w. Vegan Crusader T. Colin Campbell | Christopher James Clark

A new species of early hominid from Ethiopia. Effects of protein, monounsaturated fat, and carbohydrate intake on blood pressure and serum lipids: Diets have been constructed and judged according to their inclusion of this treasured nutrient.

An essential nutrient for the cat. Diet and chronic degenerative diseases: The Structure of Scientific Revolutions. The Dietary Protein Conundrum: First, one can comprehensively record many factors that may influence outcome even many possible health and disease outcomes in a search for consistent and biologically plausible causal factors.

The China Study – Wikipedia

The book was reviewed by Harriet Halla physician and skeptic who writes about alternative medicinein a blog entry [15] posted on the Science-Based Medicine website in J Archaeological Sci ; Not to be misunderstood that it might be the training and not the diet that led to these results, he then showed even greater conditioning when a group of already fit athletes switched to a plant-based diet.

A large part of this frustration is because:. Health and Well Being Establishing Cause and Effect between Diet and Disease One of the challenges faced by nutritional scientists when they ultimately make recommendations regarding what we should and should not eat is to establish cause and effect between a dietary element and the subsequent development or prevention of disease.

As stated in the beginning, my philosophy of nutrition is substantially different from Professor Cordain if, in fact, he even has a philosophy of nutrition, given his very negative views of this field. For example, although some observational studies have shown a positive association between animal protein and cardiovascular disease CVDit is entirely possible that this association is spurious because the measurement of animal protein is confounded by another variable that is also linked to CVD.


The average protein intake in the U. Physiologic economy in nutrition. A good place to begin understanding how much protein to consume is with the recommended daily allowance RDA, now recommended daily intake, RDI that has been repeatedly re-evaluated and re-established for the past plus years by many official bodies. Additional clues to the typical plant-to-animal subsistence ratio in Paleolithic hominin diets can be found in the foraging practices of historically studied hunter-gatherers.

An important dietary issue that has come under debate in recent years is the safety of high protein diets and their long term influence upon health and well being 17, And making matters decidedly more complicated, countless higher order interactions among the component parts cannot be accurately described or controlled.

A high-protein diet induces sustained reductions in appetite, ad libitum caloric intake, and body weight despite compensatory changes in diurnal plasma leptin and ghrelin concentrations. Third, I believe that he has put far too much weight on gene mutation events to describe the evolutionary basis for a normal, healthy diet and has overlooked the highly significant roles of epigenetic and adaptive mechanisms to also account for these same effects.

We now know that it is the nutritional control of gene expression that matters far more.

Therefore, why must studies of contemporary diet and health associations by nutrition researchers be submitted for validation by evolutionary history buffs, as suggested by Cordain?
