For Y'all Data Ground Amongst Dr. Colin Campbell Inwards The Wall Street Journal
 |
| Dr. T. Colin Campbell |
Dr. Rodriguez’s opposing persuasion raises considerable concerns equally her statements are compromised yesteryear a number of serious methodological issues as well as relies largely on inaccurate stereotypes, stereotypes scripted as well as promoted yesteryear lobbying efforts of the livestock industry that promote fright of removing animate beingness products from the diet.
Laboratory Experiments as well as the Promotion of Cancer

| Dr. Nancy Rodriguez |
It is good documented that dietary restriction of methionine significantly increases both the hateful as well as maximum lifespan inwards the rodent model.13
...the maximum-calcium-retention studies are brusk term as well as hence receive got of import limitations. To reveal how the trunk adapts to dissimilar calcium intakes over a long menstruation of time—and to larn the large film of overall os strength—requires studies of longer duration.
Walter Willett, the Chair of the Department of Nutrition, Harvard is good known for criticizing the industries unfounded claims nearly the wellness properties of dairy. In regards to the 2010 USDA Dietary Guidelines he stated that:14
The guidelines piece of job on to recommend 3 daily servings of dairy products, despite a lack of prove that dairy intake protects against os fractures as well as in all probability or possible links to prostate as well as ovarian cancers.
Willett withal praised parts of the guidelines, stating that:
The guidelines appropriately emphasize eating to a greater extent than vegetables, beans, fruits, whole grains, as well as nuts as well as highlight healthful plant-based eating patterns, including vegetarian as well as vegan diets.
Dr. Rodriguez suggested that 'The Dietary Guidelines are founded on evidence-based, peer-reviewed scientific literature, as well as accept into trouble organisation human relationship the entire trunk of research, non exactly a unmarried study', as well as that hence her dietary recommendations are justified. However, prove to the reverse was made clear inwards the study of the Dietary Guidelines Advisory Committee on the Dietary Guidelines for Americans, 2010 that stated 'The DGAC did non evaluate the components of processed meats that are associated amongst increased opportunity of colorectal cancer as well as cardiovascular disease.'15 Thus the Dietary Guidelines did non sufficiently 'take into trouble organisation human relationship the entire trunk of research', 1 of the reasons the guidelines receive got been scrutinized by the Harvard School of Public Health.13
Nutrient Density of Plant vs. Animal Foods
In regards to 'calorie efficiency', the most nutrient dense foods are nighttime greenish leafy vegetables which are leaps as well as bounds to a greater extent than nutrient dense than the phytonutrient as well as dietary deficient animate beingness foods Dr. Rodriguez advocates, piece also beingness dense inwards protein, calcium, Fe as well as zinc.17 In regards to poly peptide intake, a meta-analysis of nitrogen residual studies institute that the estimated requirements inwards salubrious adults for the median as well as 97.5th percentile are 0.65 as well as 0.83 grams of poly peptide per kg of trunk weight respectively,16 Experiments on non-human primates receive got demonstrated that intake of fifty-fifty pocket-size amounts of dietary cholesterol equally depression equally 43µg/kcal, the equivalent institute inwards exclusively one-half of a pocket-size egg inwards a human diet of 2,000 kcal induces atherosclerotic lesions. Furthermore, at that spot was no prove of a threshold for dietary cholesterol amongst honor to an adverse number on arteries (Figs. 2, 3).20 21 Furthermore, several major prospective studies on humans institute that dietary cholesterol was associated amongst a pregnant increased opportunity of all-cause mortality.22 23 24

Conflicts of Interest
Finally, Dr. Rodriguez’s fiscal necktie to the livestock manufacture may explicate why she appears to receive got misinterpreted the medical literature inwards regards to the affliction promoting effects of animate beingness foods as well as the nutrient density of plant-based foods, written inwards a largely textbook agency used yesteryear other livestock manufacture lobbyists. The tactics of the livestock manufacture may resemble those used yesteryear the tobacco manufacture that misinterpreted the medical literature inwards the yesteryear inwards gild to dismiss the 'junk' scientific discipline linking smoking to lung cancer as well as other associated diseases. Brownell et al. reminds us of how serious as well as existent conflicts of interests tin actually be:25
A smasher lawsuit occurred inwards 1994 when the CEOs of every major tobacco fellowship inwards America stood earlier Congress and, nether oath, denied believing that smoking caused lung cancer as well as that nicotine was addictive, despite countless studies (some yesteryear their ain scientists) showing the opposite.
Perhaps the same tin live said for Dr. Rodriguez’s claim that 'It is exactly untrue to advise that animate beingness poly peptide causes cancer', which is clearly inwards discordance amongst the preponderance of evidence. It peradventure largely explained yesteryear socioeconomic factors equally to why wellness regime are unable to accomplish like dietary recommendations equally Dr. Campbell as well as his colleagues. For example, Eric Rimm from the Department of Nutrition, Harvard said to Reuters inwards regards to a major wellness study produced yesteryear the National Academy of Science, which he was an writer of that:
We can’t tell people to halt eating all meat as well as all dairy produces. Well, nosotros could tell people to piece of job vegetarians... If nosotros were really basing this on scientific discipline nosotros would, but it is a flake extreme.
As Dr. Rodiguesz’s herself stated, 'appreciating the scientific discipline behind nutrition helps us brand smart choices nearly the best agency to feed ourselves as well as the world'. Unfortunately her scare tactics illustrated inwards The Wall Street Journal demonstrated really lilliputian appreciation of the preponderance of scientific evidence.
