3 Common Types of Headache (and How to Treat Them Naturally)

One major downside to having these big prominent heads stuffed with consciousness-spawning brain matter is that they sometimes ache. Nobody likes a headache. You can find fetishists who enjoy pinching, slapping, biting, burning and any matter of objectively painful stimuli. But there aren’t “headache fetishists.” No one’s chugging a 32 ounce Slurpee in search of brain […]

Did Grok Suffer from Seasonal Allergies?

Spring has sprung across most of the country. Awesome, right? Not if you’ve got seasonal allergies. Anyone with a severe case of hay fever knows how horrible it is being outside on a windy otherwise beautiful spring day with pollen blowing and rapacious bees buzzing around. Your eyes water and swell up. Your nose congests, you go […]

How Going Primal Can Help With 5 Common Genetic Mutations

As I mentioned earlier this year, our personal ancestry can help determine how we respond to certain dietary, behavior, exercise, and lifestyle patterns. The big question remaining is this: does going Primal mesh with some of the more common polymorphisms? Yes. The Primal Blueprint is a living document. Its foundation rests on pre-agricultural human evolution, but […]

4 Ways Winter Affects Your Physical Health

With winter all but officially upon us, we might already be feeling the season, maybe even planning warm weather vacations. I venture most of us have wondered if we’re not somehow healthier during the summer months. Is it just a mental vitality from the additional daylight hours and relative ease of outdoor time, or is […]

Blindspots Even Informed Paleo Enthusiasts Often Have

You read Mark’s Daily Apple every day. Paleo health, nutrition, and fitness folks populate your Twitter feed almost exclusively. You’ve got several PubMed alerts set up, helping you stay on top of the emerging evidence. Everyone in your immediate circle knows to come to you with questions about diet and exercise. You’ve been living like […]

Can Getting Your DNA Tested Help You Optimize Your Diet and Training?

Last month, I received an unexpected email request from a man named Craig Pickering: “Send me your saliva.” Craig works for DNAFit, a genetic testing company using customers’ DNA results to optimize their diet and training. He’s a former Olympic 100 m and bobsleigh (bobsled to us Yanks) athlete, and a longtime reader of the […]

You Are What Your Mother and Father (and Grandmothers and Grandfathers) Ate

On September 11, 2001, passenger jets struck the Twin Towers, leveling them, killing thousands of New Yorkers, and traumatizing tens of thousands more. Among those directly affected, but not killed, by the attack were 1700 pregnant women. Some of those women developed post traumatic stress disorder, some did not. When the PTSD-positive group had their […]

Should You Get Your Genome Sequenced?

Earlier this year, I explored the “evolution” of human dietary requirements in the last 10,000 years by examining some of the SNPs – single nucleotide polymorphisms, or variations in genetic sequences – that relate to diet and nutrition. I concluded that while certain genetic changes to the way we process certain foods have arisen in […]

What About Type 1 Diabetes?

You hear a lot about type 2 diabetes on this and other sites in the community. It’s easy to see why: type 2 diabetes is the “lifestyle” diabetes, the preventable one, the one that “doesn’t have to happen” and that you can “fix if you just dial in the food.” All true, for the most […]

Are We Pre-Programmed to Be Happy?

I think we can all agree that a basic goal in life is the attainment of happiness, that mind state characterized by positive and pleasant thoughts and emotions. But how do we become happy? By definition, happiness requires some type of pleasure to be present. We need good feelings and good physical sensations. Furthermore, the […]

Why Fast? Part Four – Brain Health

Pretty much every feature of the human body can be found, in some form or another, on other species. Opposable thumbs? Great for building and using tools, but apes have them, too. Even the giant panda has an opposable sesamoid bone that works like a thumb. Bipedalism? Helped us avoid direct mid-afternoon sun and carry […]

Maybe There is Such a Thing as Too Much Information

A couple weeks back, the LA Times published a piece on a geneticist’s experience with “personalized medicine.” Based on careful and constant monitoring of his sequenced DNA and around 40,000 health markers – or “omics” – over 14 months by a team of his colleagues, Stanford geneticist Michael Snyder observed in painstaking detail exactly what […]

Why Fast? Part Three – Longevity

A time-honored and research-tested way to extend an animal’s lifespan is to restrict its caloric intake. Studies repeatedly confirm that if, say, a lab mouse normally gets two full bowls of lab chow a day, limiting that mouse to one and a half bowls of lab chow a day will make that mouse live longer […]

How Much Have Human Dietary Requirements Evolved in the Last 10,000 Years?

A hallmark of the Primal Blueprint is that our genetics were shaped by our ancestral environment. That the foods to which we had access, the amount of sun and stress and sleep to which our bodies became accustomed, the movement patterns in which we engaged represented environmental factors that exerted selective pressure on our genetic […]

Managing Your Mitochondria: Exercise

A couple weeks ago, I wrote about how becoming an efficient fat-burner helps mitochondrial function, and last week I went over some of the nutrients and supplements most important for your mitochondria. All good and all useful, but today I’m going to talk about another route: exercise. It makes intuitive sense that mitochondria are profoundly […]

What If I Don’t Want to Lose Weight?

I receive a lot of emails from folks worried about losing too much weight on the Primal Blueprint, underweight readers who need to gain weight, or the formerly overweight who have reached their target weight and wish to stay put. No, they don’t outnumber the questions from overweight readers, but that’s to be expected given […]

Did a Wrinkle in Human Evolution Predispose Us to Diabetes?

A new mice-with-an-engineered-human-genetic-deficiency study is out that promises to shed light on why humans are so darn diabetic and obese – and the cause is an evolutionary “mistake.” A deficiency that apparently slipped through the cracks without somehow leading to our species’ demise. You see, we’re missing a genetic component shared by pretty much all […]

The Myriad Benefits of Intermittent Fasting

Calorie restriction is all the rage in anti-aging circles. A few mice and worm studies seem to show that drastic reductions in food intake over a long period of time have the effect of prolonging life – although I’m not sure I’d call it living. For one, these animals are actually restricted. There’s no ad […]

Monday Musings: Intergenerational Diabetes, New and Improved Pasteurization, Sitting is Still Bad, and Really Old Wine

Diabetes is that rare brand of nasty disease that fails to strike real, visceral fear. It doesn’t carry the weight of a cancer or an AIDS or a heart disease. It’s something you get, like a gut, a long list of prescriptions, and a walker, as you grow older. People just live with it – […]

Why Can Some People Eat Anything They Want and Never Gain a Pound?

The following are both actual and paraphrased versions of questions I regularly get from readers: If grains are so bad how can you explain the leanness and good health of Clarence Bass? How is it that this guy can eat 30 bananas a day and not gain weight, or this guy can eat nothing but […]
