Processed, Cured and Smoked Meats: Definitely Not Paleo!

As more and more people adopt the Paleo Diet, controversy has arisen as to which dietary elements actually comprise a contemporary “Paleo Diet”.  Or more precisely, which current foods, food groups or food additives should be included or excluded in modern day diets as we try to emulate the nutritional characteristics of our pre-agricultural ancestors?   A number of popular-day and charismatic bloggers suggest that processed meats such as bacon and other cured, processed and smoked meats should be part of contemporary Paleo Diets on a daily basis (1-3).   Surprisingly, one of the contested elements that charismatic bloggers advocate

A Rare, and Never Before Published Book Chapter Concerning Salt and Cancer

When I was in the middle of my academic career during the mid to late 1990’s (I retired from Colorado State University in December 2013,) I had the great pleasure of corresponding with Birger Jansson, Ph.D. at the University of Texas, M.D. Anderson Cancer Center in Houston, Texas. Dr. Jansson was a Professor in the Department of Biomathematics at the M.D. Anderson Cancer Center and worked as a biomathematician for the National Large Bowel Cancer Project (NLBCP) between 1973 and 1983 when President Nixon launched his war against cancer in the early 1970s. Birger was known internationally for his brilliant

Dr Cordain Answers a Reader’s Question About Egg White Lysozyme

Hi Dr. Cordain, I read the lysozyme article and I am wondering if you could please indicate if egg white lysozyme is more readily bio-available raw or cooked? If egg whites are consumed by eating them raw or cooked, does the body actually have the ability to put it into bloodstream and utilize the lysozyme? In other words – what is the big deal if a human cannot even utilize it if it is digested and broken up or if it cannot be absorbed if raw or cooked? How would evolution have made lysozyme more available – cooking, selection of

Dietary Salt Impairs the Endothelial Glycocalyx: The Most Important Cardiovascular Disease Risk Factor You May Never Have Heard About

Frequently, important physiological discoveries made by scientists who study obscure topics escape the attention of the general public, health professionals, and even other scientists.  Such has been the case for the endothelial glycocalyx: a delicate and fragile structure lining the inside surface of all blood vessels. The endothelial glycocalyx had been inferred from blood flow measurements as far back as the 1940’s, but due to its fragile configuration the structure had never been viewed until 1966 when it was first detected with an electron microscope using special staining procedures (1).  Over the next 30 years, scientists speculated about the function

Further Evidence Against a High Sodium Paleo Diet

An ongoing controversy about dietary salt (either refined salt or sea salt) in human ancestral diets represents a significant point of contention for the Paleo Diet community.  Some popular bloggers contend that ingested high levels of dietary salt have no adverse effects upon our health and wellbeing1-10.  My scientific colleagues and I disagree with these conclusions11-34.   The Table below clearly demonstrates that high sodium diets (greater than 2300 mg/day) are virtually impossible to achieve when eating a 2000 to 2500 kcal/day diet consisting of normal selections of un-adulterated, non-salted wild or domesticated foods.

The Sea Salt Controversy: Important Updates for Your 2017 New Year’s Resolution

Introduction: The Belief that Added Salt is Paleo Look no further than the increasing number of bestselling “Paleo” diet cookbooks1-7, or “Paleo” diet website recipes8-16 and you can fully appreciate the near unanimity of authors whose recipes embrace sea salt or salt as fundamental ingredients in an otherwise Paleo-friendly meal. Somehow, somewhere most people in the Paleo community have been led to believe that added sea salt or salt can be safely included in contemporary Paleo diets with no long-term, adverse health effects, and that high salt intakes were a normal part of ancestral, hunter-gatherer diets. At least, this is

Pomegranate: Perhaps, Paleo’s Healthiest Fruit

Introduction In Colorado, late fall will shortly be upon us and we will fade into early winter and beyond. For many Paleo Dieters throughout the U.S., this time of season represents the closure of fresh farmer’s markets and the end of the delicious local fruits and vegetables they produce. Nevertheless, late fall and October also signify the beginning of the Pomegranate season, which in California (the major U.S. producer) runs from October through January1. I am eagerly looking forward to munching down on this succulent and health-giving fruit. In fact, pomegranates are so healthful that they have been described as

Eliminating Non-Paleo Foods Improves Nutrient Density

[Part Three in our Series on Why the Paleo Diet is a Nutrient Dense Diet, by Trevor Connor, M.S. and Loren Cordain, Ph.D.] Possibly the biggest criticism made against the Paleo diet is that by eliminating multiple food groups (grains, dairy, legumes, and starchy roots) the diet can cause nutrient deficiencies. In fact, this argument is a major reason why the Paleo diet remains at the bottom of the US News and World Report’s Best Diet Rankings. In their rationale, US News stated “slapping the diet with multiple low ratings, the experts couldn’t accept that entire food groups, like dairy

Dr. Cordain Responds to Critics of a Recent Paleo Diet Study

[Part One in our Series on Why the Paleo Diet is a Nutrient Dense Diet] In April, news of a recent two-year study exploring the effects of a Paleo diet on postmenopausal women was presented at the 2016 Endocrine Society Annual Meeting. Soon afterwards, an article hit the web detailing the positive results, but quickly shifted its focus to interviews with members of the nutrition community who focused more on their issues with the diet. In this part 1 of our Nutrient Density Series Dr Cordain addresses these critiques and shows that when you just delve a little deeper into

Quinoa and Saponins: Dr. Cordain Responds to a Reader’s Question

Some people following the Paleo diet eat quinoa and other pseudo-grains as grain alternatives based on the encouragement of others in the nutrition community who tout quinoa as a “super-food.” Dr Cordain answers a reader’s question about why the high saponin content of quinoa can cause digestive issues and why we should be careful about reading too much into any single study. Dave Chiasson on August 24, 2016 wrote: I just read this: “What the Science Says Emerging research appears to contradict the idea that saponins from quinoa cause inflammation. Researchers examined the inflammatory effect of saponins from quinoa. Contrary
