September Series: All About Calcium

One of the biggest criticisms of the Paleo diet is that it typically has a lower daily calcium consumption than a “healthy” western diet. This is especially concerning to many Paleo critics who point out that osteoporosis is becoming one of the most common chronic conditions in the western world. Calcium supplementation and milk consumption have become so ingrained as part of “healthy living” that it’s hard to leave your doctor’s office without a blood pressure test, a heart rhythm check, and a calcium prescription. Yet, despite this huge focus on increasing our calcium intake, there seems to be little

6 Reasons Why People Quit Paleo

People join the Paleo challenge for a variety of reasons including weight loss,1 the significant health effects on blood pressure, blood sugar, and cholesterol levels, 2,3 or simply the overall lifestyle improvements.4 But there are an equal number of reasons why folks jump off the Paleo wagon. From a purely psychological standpoint, self-sabotaging behavior,5 all-or-nothing thinking,6 and the fact that no one likes to be on a “diet” are just a few. Here are six common reasons that ex-Paleo folks and Paleo experts identified why people quit: 1. It’s hard to be Paleo during vacations. Louise Hendon, co-founder of Paleo

Archeological Breakthrough Indicates Hominin Predecessors Were Sophisticated Hunters

Recently archaeologists in northeast Jordan have discovered the oldest known tools with identifiable protein residues—the residual remains of butchered animals.1 Between 2013 and 2015, a team of archeologists excavated 7,000 tools used by hominins around 250,000 years ago. These tools provide significant insights into the hunting sophistication of early proto-humans. More importantly, the study further discredits the myth that early hominins were predominantly vegetarians. First, let’s examine what this new archeological evidence reveals about ancient hominins from present-day Jordan. The specific location is the Azraq Basin of Jordan’s Eastern Desert, a hominin habitat for the past 300,000 years. Its first

The Paleo Diet August Digest – Revisiting Some Dietary Bad Guys

Looking Back On August  Welcome Paleo Diet readers to our first monthly digest! This is your chance to catch up on the many great articles written by our team on topics we think you’ll find interesting. In August, some exciting new research and Dr Cordain’s continual quest to find the dietary answers to optimal health led us to revisit a few of those dietary bad guys we can all do without. Perhaps most exciting is new research on two of the biggest culprits – a study showing wheat sensitivity has true immunological consequences and another addressing sugar addiction. But that

Autism, Aspartame, and the Paleo Diet

Some time ago, a colleague introduced me to the work of Woodrow Monte, Ph.D..  Dr. Monte has dedicated his academic career to the research and teaching of the composition and safety of foods.  For more than 25 years he has raised serious concerns about the consequences of Aspartame/methanol consumption. A Google search regarding methanol toxicity from aspartame consumption will produce a mix of results for and against Aspartame safety.  A typical pro safety position can be found at the website, which states: “When your body processes aspartame, part of it is broken down into methanol. Although toxic in large

Zzzzz… Paleo Sleeping Surfaces

For most people, seeking better health and well-being through a Paleo lifestyle is purely a dietary choice. However, some of the more curious and adventurous spirits out there are willing to experiment with other aspects of their life for further health gains.  An often overlooked, but certainly important aspect of leading a Paleo lifestyle is sleep quality. Our Paleo ancestors certainly didn’t have cushioned king mattresses or posturepedic comfort foam. They slept on a variety of surfaces that sometimes had more to do with what was available. But the question is whether mattresses are a truly welcome advance or if

Is Sugar Addictive?

Sugar is likely the most over consumed substance in the modern world 1 On top of our endless addiction to soda (sugar water essentially) – sugar is surreptitiously added to nearly every processed food.2 As a result, the United States Department of Agriculture (USDA) now reports that the average American ingests 150-170 pounds of sugar per year.3 This overconsumption of sugar may very well be killing us. As I’ve previously written, sugar is the precursor and the ‘canary in the coalmine’ – to numerous diseases and unhealthy conditions. Diabetes? Check.4 Obesity? Check.5 Even Alzheimer’s has been directly linked to too

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 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
