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

Study Finds Multigenerational Vegetarians Are Genetically Predisposed to Cancer and Heart Disease on a Modern Diet

It’s no secret that vegetarian diets pose unique nutritional challenges. Protein, iron, vitamin D, and vitamin B12, for example, are nutrients vegetarians typically struggle to obtain optimally. Often overlooked, however, are the important differences between animal and vegetable foods with respect to essential fatty acids (EFAs). As we’ll see, vegetable EFA sources are inferior to animal sources and, according to research recently conducted by Cornell University scientists, these shortcomings promote genetic adaptations, which make intergenerational vegetarians more prone to inflammation-related diseases, particularly cancer and heart disease 1. The EFA Basics The only fatty acids considered “essential” are polyunsaturated fatty acids

Fueling to Perform…with Food

“Just get the calories in, it doesn’t matter where they’re coming from.”   “As an endurance athlete, you need to consume a lot of carbs to fuel that training.” “You can’t train too long on an empty stomach; you’ll get dizzy and it could be dangerous.” Wow! It’s overwhelming, isn’t it? Sadly, these three misconceptions are just the tip of the iceberg when it comes to understanding how we need to fuel our bodies for sport. As a long time ironman triathlete who’s been racing for nearly 20 years, I can honestly say that I’ve probably tried every gel, sports

Ancestral Solutions for A Sluggish Thyroid

Do you feel tired? Is your mood unusually low? Do you have steady weight gain despite eating well and exercising? If you answered “yes,” your thyroid may be struggling to keep up with the demands of daily life. Your thyroid gland effectively sets your body’s thermostat and metabolism. It can be sluggish when the conversion from your body’s primary thyroid hormone – thyroxine (T4) – to the “active” or useable form – triiodothyronine (T3) – is impaired. This condition is often termed subclinical hypothyroidism because patients can exhibit some of the classic symptoms of hypothyroidism – fatigue (especially in the

Transition to the Paleo Diet Without the Headaches

Are you afraid to transition to the Paleo Diet because you’ve heard you might feel like you have the flu for the first week? The low carb flu symptoms consist of headache, fatigue/weakness, achy muscles, and brain fog.1  Some people have exclaimed, “The Paleo Diet is not for me, I felt terrible eating that way.”   The Paleo Diet is not to blame.   What is at fault is actually not being patient with the transition time required to reset your body’s metabolic process, as well as a few simple errors in the application of the Paleo Diet’s guidelines.

Medical News Today – Media Response to “Paleo” Mice Study

Medical News Today demonstrates that they put scientific accuracy first and are taking steps to correct their recent article. March 17th, 2016 Dear editorial board, Many thanks for your follow-up email regarding the following article: I can confirm we have amended the caption to reflect that the researchers report that the mice on the “Paleo” diet gained 15% of their body weight, and we have also amended the article text to state that the report claims that the mice gained this weight after 8 weeks on the said diet. Additionally, we have contacted the study authors asking them to clarify

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

The Paleo Diet Response to Media on Misleading Mice Study Claims

March 16th, 2016 Dear Ms. Ellis, Thank you for responding to our letter. An open dialogue and discussion is always appreciated. While we respect that the author may have been expressing the opinions of the study’s author we do not feel that was made at all clear in the article. The article starts with a discussion of the Paleo diet without any attribution to the authors. More egregiously, the caption below the picture at the top of the article reads “Mice on a Paleo diet gained 15% of their body weight in less than 2 months”. Nowhere does it state that was

Embracing Your Inner Paleo Chef

It’s often said that meat made us human. Meat allowed for larger brains and greater intelligence, not to mention more time for pursuits other than chewing. So how did a species that ate relatively little meat 2.6 million years ago evolve into one that depended on meat and was radically transformed by its consumption? Do we owe this success to fire and our learned ability to cook? Or does a more rudimental form of “cooking” deserve the credit? As every chef knows, you don’t just toss whole vegetables and large slabs of meat into the casserole. You have to slice

Response to Media on Recent Mouse Study

Two weeks ago, media outlets around the world published articles strongly questioning the Paleo Diet based on a single high-fat study on mice. We always enjoy seeing articles about the diet, whether it’s a testimonial, a new discovery, or even criticisms about the science because it’s only through scientific debate that we arrive at better answers. But we draw our line at unfounded claims and poor research. This week contacted many of these media outlets asking for a correction to their unfounded claims. A sample of our letter (sent to Medical News Today) is published below: I am writing
