Dear Mark: PUFAs

In last week’s Dear Mark I took up a reader question about trans fats. While we’re on the fat subject, I figured it was a good time to keep the conversation going and cover an email I got last week about polyunsaturated fatty acids (PUFAs). Thanks to Brent for this one. I loved your posts […]

The Definitive Guide to Oils

Before you can hope to make it as a speculator and start slingin’ barrels for big money, you’ve got to understand exactly what’s gushing forth from the earth’s crust. Yes, that’s right – it doesn’t start and stop just with crude, and there’s far more to oil than dinosaur bones. In fact, most experts agree […]

The Wonderful World of Coconut Products

Coconut seems to have a special place in Primal hearts. Judging from the forums, people are pretty taken with the fatty pseudo-nut and they’re always interested in new ways to consume the stuff. For some who abstain from dairy completely, coconut products make a great replacement for creams and butters. Others see the evidence from […]

Dear Mark: Trans Fat

The message has been circulating for a few years now: trans fats = bad. It’s one of the rare times I find myself in alignment with conventional nutritional guidelines. (Of course, it’s not so simple, but I’ll unpack that one in a moment.) The fact is, manufacturers have done a better job sending the anti-trans […]

Dear Mark: How Primal is Hemp?

As I’ve always said, part of the Primal Blueprint’s power is its continuing evaluation and evolution. As a broad lens defined by tried and true physiological principles, the PB can effectively assess and (when appropriate) seamlessly accommodate “new”/rediscovered practices and foods. Readers send me questions all the time that help redefine or further confirm the […]

Is Canned Food Safe to Eat?

Ideally, The Primal Blueprint is a living, breathing document. Whether it’s emails from insightful readers or random articles from my RSS feed casting a subject in a completely different light, or even personal N=1 revelations spurring a meticulous re-examination of previously-held stances, I’ll often find myself rethinking certain aspects of the PB. They usually hold […]

Is Organic All It’s Cracked Up to Be?

Several months back, a major study comparing the nutritional value of organic food to conventional food made the rounds. Organic food, it found, was “no healthier” than ordinary food. There were no significant “differences in nutrient content,” and the study’s authors found “no evidence to support the selection of organic over conventionally produced foods on […]

Dear Mark: Arachidonic Acid

I spend a lot of time highlighting the importance of omega-3 fatty acids and downplaying their poly cohorts, omega-6s. Of course, I do this for good reason. Western dietary patterns and modern agricultural practices have made omega-3s harder to come by and blown any semblance of omega-3/omega-6 dietary balance out of the water. As maligned […]

The Definitive Guide to Fermented Foods

Life in the Paleolithic wasn’t a pristine, sterile existence. There were no fun-sized hand sanitizers or pasteurized eggs. Meat didn’t come shrink-wrapped, and it wasn’t stored in sub-40 degree temperature to prevent spoilage. I’ve never seen evidence of vegetable cleaning liquid containers at prehistoric dig sites, nor have any tiny tubes of antibiotic ointment been […]

Dear Mark: Primal Trail Food

Just when you feel you’ve made the successful transition to Primal eating in everyday life, you stumble upon a scenario that sends you back to the drawing board. For some people, it’s the holidays. For others, it’s travel. For reader Brian, it’s regular camping trips into the real “primal environment”: Dear Mark, Each summer and […]

Dear Mark: Your Brain on Junk Food

Clearly, we eat not just to fill our stomachs but to satisfy a whole host of biochemical drives. The brain is built to incentivize our efforts not just with the quieting of hunger pangs but the kick-starting of an intricate hormonal “reward” system. When it comes to diet, I’ve always said what nurtures the body […]

Why Grains Are Unhealthy

I find that grain bashing makes for a tasty, but ultimately unsatisfying meal. You all know how much I love doing it, though. But no matter how often I sit down to dine on the stuff (and I’ve done it with great gusto in the past), I always leave the table feeling like I left […]

Trick or Treat: Yea or Nay?

There are menacing spirits about tonight. Truly horrifying, ghastly ghouls in shiny, enticing packages. Resting ominously in bowls, baskets and bags, they await their jolly little prey. With the power of the Pied Piper, they will lead all manner of small witches, scarecrows, Spidermen, vampires, princesses, cowboys and gypsies toward ebullient, screeching glee, then sugar […]

How to Maintain Muscle While Losing Weight

“Losing weight” is insufficient terminology. It’s too vague, too unspecific. When a person sets out to lose weight, just what are they trying to lose? Bone density? Muscle mass? Organ weight? Of course not – they’re generally looking to lose adipose tissue. People want to burn body fat, and they want to do it without […]

Dear Mark: How to Stay Healthy in College

College students and healthy lifestyle. On the one hand it seems like the ultimate contradiction. Pizza boxes, Red Bull cans, Doritos bags, beer bottles, Captain Crunch at every cafeteria meal. They’re as much a cultural vision of college as John Belushi’s sweatshirt. If there were a Primal no man’s land, you’d think the residential campus […]

Choose Your Booze: A Guide to Healthy Drinking

It’s the question every Primal adherent faces: how does alcohol fit into a low carb lifestyle? Maybe you’re out with friends, bravely resisting the assorted chips and fried concoctions in the center of the table. You don’t mind waiting patiently for the steak and salad you conscientiously selected, but must you be relegated to the […]

10 Ways to Quench a Primal Thirst

I’ll admit it. For the most part, beverages don’t get a lot of attention around here. I tend to take a pretty dismissive stance on them, perhaps as a reaction to the ridiculous mainstream obsession with water intake (64 ounces per day? C’mon!). Also, besides the occasional hankering for a cold beer, I don’t really […]

Dear Mark: Contest Questions

For this week’s post I’m dipping into the hundreds of comments-questions I received for the Contest last month. Although I could highlight only a few for the winning set, I appreciated all your responses and will try to cover as many as possible in upcoming posts. Thanks, everybody! Mark, As part of my more primal […]

Who You Callin’ Stupid and Lazy?

A number of readers have sent me links (thanks, readers) to a new study coming out of the UK that raised some eyebrows all across the Internet earlier this week. The headlines seemed to scream from everywhere “Do High Fat Diets Make Us Stupid and Lazy?” That, in turn, made me scream, so I took […]

Contest Results: Q&A with Mark

Congratulations to Ed, Wyatt, Ken, VN, and Dan. You have won copies of The Primal Blueprint. As Aaron mentioned, we received nearly 250 fantastic questions. I could spend the next few months writing blog posts to address these questions exclusively. Needless to say, I’ll be using the comment board as a source of future MDA […]
