Fort Collins, CO (PRWEB) December 19, 2014
Barely a day goes by without an individual or group attacking the Paleo Diet. Because the Paleo Diet eliminates grains, legumes and dairy, it has come under fire from companies and corporations that are financially vested in producing products for these food groups, respectfully. One might not expect, however, for organizations that, in their own words, use the most up to date public health and scientific research on food, health and disease, which they translate into practical guidance to enable people to make appropriate lifestyle and food choices, to do the same.
Last week the Daily Mail newspaper reported on the British Dietetic Association (BDA) revealing its annual list of the Top 5 Celebrity Diets to avoid in 2015. A tagline contained in the graphic states, Being famous does not make someone an expert on diet. Based upon telephone calls and other contributing factors, they ranked the Paleo Diet second, surpassed by the Urine Therapy Diet. While there are many celebrities (and, top professional athletes) that have adopted the Paleo Diet, including the diet in the British Dietetic Association’s “Top 5 Worst Celebrity Diets” suggests the diet is not supported by research and is, by the mainstream vernacular, a “fad diet. After outlining the major tenants of the diet fairly accurately, the Daily Mail then provides the BDA Verdict:
Jurassic fad! A diet with fewer processed foods, less sugar and salt is actually a good idea, but unless for medical reason, there is absolutely no need to cut any food group out of your diet. In fact, by cutting out dairy completely from the diet, without very careful substitution, you could be in danger of compromising your bone health because of a lack of calcium. An unbalanced, time consuming, socially isolating diet, which this could easily be, is a sure-fire way to develop nutrient deficiencies, which can compromise health and your relationship with food.
In the very first statement, the BDA recognizes the Paleo Diet is beneficial by eliminating the processed foods typically found in most Western diets. However, they quickly move into the misconception that by removing certain foods from the diet (i.e., grains, legumes and dairy), without very careful substitution, one will likely suffer nutrient deficiencies.
This is a classic position from those that are against the Paleo Diet. Completely removing a number of food groups that have been staples in their diet for so many years, may seem less than prudent. However, it is not difficult to run a nutritional analysis on any true Paleo meal that have these elements removed and realize that not only are there no deficiencies, but the nutrient density for the 13 nutrients most lacking in the US diet, compared to the USDA Food Plate (formerly the Pyramid) actually improves, including calcium. For those following a Paleo Diet, substitution is unnecessary when they adhere to the Paleo template that nature has served will provide this nutritional benefit. In spite of this, one should be aware of the hypocrisy of the BDA on this issue. Both the BDA and The Academy of Nutrition and Dietetics (formerly the American Dietetic Association) endorse vegan diets, which eliminate dairy, meat and fish. Accordingly, the BDA is hypocritical in their criticism of the Paleo Diet for eliminating dairy.
There are now hundreds of thousands of physicians, naturopaths, nutritionists, chiropractors, conditioning coaches, and other healthcare professionals who advocate for the Paleo Diet and rely on results for their businesses to be successful. As a consequence, millions of people have benefited from adopting this way of eating. The BDA has ignored this reality where testimonials are many across the many dedicated Paleo Diet websites to date and instead, suggested the diet will be short lived.
The organization that claims to use the most up-to-date scientific research to form their positions, failed to recognize the 15 human experimental studies on the Paleolithic Diet that demonstrate a benefit to adopting this dietary template.*(1-15) In all clinical trials to date, the Paleo Diet outperforms the Food Plate, the Mediterranean Diet, and diabetic diets for a variety of clinical endpoints including weight loss and cardiovascular disease symptoms. There are also many more peer reviewed scientific papers that lend support to the Paleolithic Diet template with which the BDA might benefit from becoming a little more familiar when advising and educating their base.
A few important points that can be found within the published research referenced above that would be unknown to the BDA follow. Humans have no whole grain dietary requirement. In fact, whole grains are one of the worst food groups in terms of their nutrient density for the 13 nutrients most lacking in the US diet and are poor sources of fiber compared to fresh fruits and vegetables. Around 5% of the UK (~3.25 million people) and US (~16 million people) populations have either celiac disease or gluten intolerance. Gluten containing grains increase intestinal permeability via the upregulation of zonulin (a protein that modulates the permeability of tight junctions between cells of the digestive tract), and this increased permeability promotes chronic low level inflammation, a universal characteristic underlying CVD, cancer and autoimmunity. Whole grains also contain phytate and other antinutrients, which impair divalent ion absorption. Further, wheat contains wheat germ agglutinin (WGA), which likely enters the systemic circulation (not in plasma but bound to formed elements) and can interact with the immune system. And 65% of the worlds people are lactose intolerant and have no ill effects from eliminating dairy from their diet.
Critics of the Paleo Diet need to understand a very important issue. Unlike the vast majority of diets out there, no one person has formulated this diet. It is based on the concept of evolutionary dietary selective pressure and all of the published research on the diet has attempted to examine the concept that following a diet that humans evolved with over a long period of time, may provide an optimal dietary template. The vast majority of the published data and the clinical findings, to date, support this idea. Researchers in this field of evolutionary nutrition are more than open to being shown research to the contrary; but, respectfully, would request that the data shows that, not someones opinion.
A response to an article critical of the Paleo Diet written by Professor Sydney Finkelstein (@SydFinkelstein) was published on The Paleo Diet Blog on October 13, 2014 in an attempt to engage Professor Finkelstein to support the points in his article and counter the critique that published data were used to formulate the position. However, the response simply stated that to suggest that the science behind the diet is incontrovertible, or that questioning the Paleo prescription is an affront to logic, is ludicrous. An initial critique of the Paleo Diet with no scientific support is rebutted with the published data and the comeback is to state that the Paleo Police are unhappy about their diet being questioned. For those involved in the research and clinical trenches, that could not be further from the truth; the counter arguments need to have some published data supporting them or at least some substance with sound logic so that further research can be conducted based upon those arguments to help determine what may be an optimal diet for human health and performance.
Dr. Loren Cordain, the very founder of the modern Paleo Diet movement, demonstrated an example of being open minded when he changed his position on dietary saturated fats. Upon re-examining his initial work through the lens of the evolutionary template, he realized a different conclusion. And there is no evidence that that wouldnt happen again if an argument or data showed a flaw in an original position or research findin
