Revisiting Sea Salt: Dr. Cordain Responds to a Reader’s Comment

As the Paleo movement has grown, many within the community have broadened the original template to include other ingredients that we at ThePaleoDiet.com do not feel should be included as a Paleo staple.  This is not to say that these additions should never be consumed, we have always agreed, that for most people, non-Paleo foods can be included in a healthy diet with an 85:15, Paleo:non-Paleo ratio.  But even if an ingredient can be argued as natural, one should still assess the likely availability, and hence its evolutionary influence upon humans, while also examining the current scientific literature with respect

One More for the AGES: Dr Cordain Responds to Reader’s Questions about Advanced Glycated End Products

More than most sciences, the nutrition world is rife with debate and wildly different recommendations. Normally the debates center around our common knowledge of nutrition: macro- and micronutrients; glycemic index; caloric balance; etc. But sometimes it’s what we don’t know – or at least what few know – that’s important. One example is Advanced Glycated End Products or AGEs. Still new and not well understood within the nutrition world, these molecules can have a big impact on our health. And they are found in our food. Loren Cordain, PhD explained AGEs in a recent post, but you our readers asked

Obesity in the Paleolithic: The Odd Case of the Venus Figurines

Introduction: Obesity in Western Societies Unless you’ve been camping out for the past 20 years, you are probably aware that Americans are the fattest people in the world.  The latest National Institute of Health (NIH) survey indicates that 68.8 % of all American adults are overweight or obese.   The easiest way to determine body composition and weight classification is to calculate the body mass index (BMI). Simply divide body weight in kilograms (kg) by height in meters squared (Table 1). Table 1.  Body Mass Index (BMI) categories where BMI = [body weight (kg)/height (m2)].  World Health Organization (WHO), 2004

Pemmican: A Plains Indians Staple Food that Prevented Protein Poisoning

Introduction In a previous blog post (http://thepaleodiet.com/north-american-plains-indians -tall-and -robust-meat-eaters-but-not-a-milk-drinker-among-them/) I demonstrated how the diets of North American Plains Indians during the 19th century allowed them to become the tallest humans in the world. All available evidence indicates 1-4 that they ate a very high (76–85% of total calories) 1 animal based diet throughout their lives, primarily from consumption of buffalo (Bison bison) meat and organs, as I have shown in my last blog post. With a high animal based diet, one of the inherent problems that these peoples surely must have known was that unlimited and high consumption of lean

Cordain Answers to Reporter on “Pegan” Diets

Elizabeth BizWest asks: 1. Are you following a strictly Paleo or Vegan-Paleo (Pegan?) diet and can you say something about the best way for someone to address the contradictions between the two if they are vegan? 2. What are the primary challenges people face for the combination of these 2 diets? 3. Do you or people in general follow this diet on a temporary or a permanent basis and why? 4. I’ve read that it’s more the modern preparation of foods like legumes and pseudo-grains like buckwheat and quinoa than the foods themselves that puts them off-limits for Paleo dieters

North American Plains Indians: Tall and Robust Meat Eaters, But not a Milk Drinker Among Them

George Catlin, the famous chronicler of American Indians, circa 1832, glowingly used these words to describe the Crow Tribe, “They are really a handsome and well-formed set of men as can be seen in any part of the world. There is a sort of ease and grace added to their dignity of manners, which give them the air of gentlemen at once. I observed the other day, that most of them were over six feet high . . .” “It is but to paint a vast country of green field, where the men are all red – where meat is

Vitamin D: One of the Few Supplements Paleo Dieters May Require

One of the most persuasive aspects of contemporary Paleo Diets is that you will not have to waste your hard earned dollars on supplements (1, 2).  Once you get going on this lifetime program of eating, except for Vitamin D and possibly fish oil, you will achieve all of the DRI’s recommended by governmental agencies from just the food you eat (1, 2).  Previously, I have extensively covered the calcium issue in a number of scientific publications (2-4), so in this blog, I want to re-emphasize the importance of vitamin D supplementation for health and well being.  As we come

Loren Cordain, Ph.D. Response to Mouse Study

I have previously commented upon this single short term mouse study. You are correct in stating the obvious, nowhere in the original article did the authors indicate they were testing a “The Paleo Diet” but rather a low-carbohydrate, high-fat diet in an unusual animal model (prediabetic New Zealand Obese (NZO) mice, rather than in humans.   This single study apparently, seems to be one that the Australian popular press has focused upon and distorted the more far ranging implications of this study.  Yet the study totally lacks the criteria and objectivity by which most of the scientific, nutritional community uses to

Is Maca Root Powder Paleo?

Dear Dr. Cordain, Thank you for your great YouTube vidoes and your website. I found them last week after some detours through a few pale imitators, and have begun transitioning to the Paleo diet according to your interpretation, which I consider to be the most authentic. In only about a week, I am feeling much less bloated, have fewer cravings, and think my body looks slightly different. I love how deeply the foundations of the diet have been researched and how well you explain it. I have a question about maca root, which I have just learned is from a
