Dear Mark: Flexibility vs. Mobility, Orange Skin, and Radioactive Matcha

I’m going to keep today’s question and answer session rather brief. I’ll be covering three topics: flexibility and mobility; carotenoderma, or the orange-ing of the skin following ingestion of carotenoid-containing foods; and whether matcha green tea from Japan poses any threat due to radioactive contamination. For the first, I discuss whether it’s flexibility or mobility […]

The “Asian Paradox”: How Can Asians Eat So Much Rice and Not Gain Weight?

How the Primal community loves the concept of a dietary paradox. How we eagerly point to its various manifestations as supportive evidence for our way of eating, living, and moving. You know the French Paradox and how it confounds the experts. To mention all those smug surrender monkeys with their brie and their butter and […]

Why the Night Sky Matters: The Ramifications of Light Pollution

Carrie and I are lucky enough to have a hot tub in our back yard, overlooking a pretty spectacular ocean and mountain view. We often soak for a while and talk about the day’s activities just before retiring to bed (I sometimes alternate with a quick plunge or two into our unheated pool). Last night […]

The Pill: What You Need to Know About Oral Contraception

Over the years I’ve received questions about the Pill on a pretty steady basis. As one female reader put it, if you go Primal and do all the work of normalizing your hormones, does taking the Pill undo all the good? Are the cautionary rumors I hear just overblown, or are there substantial risks? What […]

The Relationship Between Exercise and Inflammation (and What It Means for Your Workouts)

Since we’ve been on an inflammation kick the past couple weeks, I figured I’d start covering some of the areas of health and lifestyle that interact with inflammation. That doesn’t exactly narrow things down, seeing as how inflammation is involved in just about everything, but it does give me plenty of things to discuss. Today’s […]

Are Your Canned Foods Safe to Eat?: A BPA-Free Buying Guide

By now, you’re undoubtedly aware of BPA, or bisphenol A, and its ubiquitous presence in can liners, plastics, and even receipts. I wrote about its status as a xenoestrogen with the ability to interact with hormonal receptors in animal bodies, as well as its potentially deleterious effects on humans – especially tiny growing humans – […]

How to Tell If You’re Inflamed: Objective and Subjective Inflammatory Markers

In the comments section of last week’s post on inflammation, many of you expressed a desire for a post explaining how to know if one is actually suffering from systemic, chronic inflammation. I thought that was a great idea and decided to put the other followups on hold so I could tackle this one. Obviously, […]

Dear Mark: Fat Causes Brain Damage?

It feels good to get back to our regularly scheduled Monday morning programming. “Dear Mark” is a way for me to keep my finger on the pulse of the community, to respond quickly and directly to any issues that may arise. I try to keep abreast of all this stuff, but there’s a lot, and […]

Dear Mark: Salt and Blood Pressure

The salt debate rages on outside these halls, but I’ve never really opened MDA’s doors to the tempest (beyond a short dalliance several years ago). Today, though, I am. We’ve likely all consumed a fair bit of sodium chloride over the past holiday weekend, and I imagine a few of us are wondering whether that’s […]

How to Interpret Cholesterol Test Results

Before we get into the big job of interpreting cholesterol numbers, let’s review what cholesterol actually is. Cholesterol is cholesterol: a waxy steroid of fat that serves as an essential structural component of cellular membranes and in the production of steroid hormones, vitamin D, and bile acids. Contrary to what the terminology indicates, there’s actually […]

Tails, Tendons and Tripe: A Guide to Discovering the Odd Bits

Put down your rib-eyes, don’t thaw those chicken legs just yet, and step away from the pot roast. Don’t get me wrong – those are fine examples of animal muscle meat. Delicious, even. But they’re not all that we should be eating. Not by a long shot. Allow me to explain. The other day, I […]

Dear Mark: Sun Beds, Skipping Breakfast, Cooking with Essential Oils, and Glycerol

It’s Monday, which means it’s time for another round of Dear Mark questions and answers. This week I’m answering four reader inquiries. First, I discuss the suitability of tanning beds, and try to give the best answer I can muster given the lack of hard evidence either way. Next, I cover whether or not a […]

10 Holiday Gifts for Your Primal Tribe

It’s holiday time, at least around here, and that means gift-giving. And since you’re reading this post, you’re likely a card-carrying Primal fanatic who would like to see as many people involved in this lifestyle as possible. If that’s the case, tailoring your gifts to the Primal lifestyle could be a great way to get […]

How to Train for a Marathon

Leading into this post, I promised myself that I wouldn’t try to dissuade people from running marathon(s) or any long distance races. I already do that plenty in other posts, so today’s is geared toward the folks that simply are going to run a marathon or marathons, regardless of what I say. I know these […]

Dear Mark: Are Peas and Green Beans Healthy?

For today’s Dear Mark post, I’m going to hold off on doing a big roundup and instead focus on a single question that keeps appearing in my inbox: the suitability of green beans and peas in a Primal Blueprint eating plan. I regret not getting to it sooner, for I can imagine the Vibram-clad pausing […]

How to Eat More Fat

The leaders of the dietary establishment either keeled over or started arming themselves with pitchforks as I wrote that title. (It’s a good day to enjoy the subversion, I think.) On a serious note, let me unpack this worthy question – one I tend to get often: how does one incorporate more fat into a […]

Flatulence: Foes and Fixes

Farting is universally hilarious. Across every culture, every religion, every language, the issuance of gas from a person’s posterior will – once the wrinkled noses have smoothed out – evoke laughter from just about everyone in earshot. I won’t try to explain why it’s so dang funny, especially when we can turn to Louis C.K. […]

The Problems with Antibiotics: Possible Alternatives and Damage Control

Are there any viable alternatives to antibiotics? I just spent the last few posts talking about all the bad things that stem from taking too many antibiotics, and you’re likely wondering if there’s anything you can do when an infection comes around. Although I wouldn’t suggest ignoring your doctor’s antibiotic prescriptions for some herb you […]

The Problems with Antibiotics: More Fallout from Killing Your Flora

A new study found that pediatricians are over-prescribing broad spectrum antibiotics (which target both gram-negative and gram-positive bacteria, also known as most bacteria) at an increasing rate. 21% of all pediatric visits ended with a prescription for antibiotics, 50% of which were broad spectrum. For 23% of those visits ending in antibiotics (which accounted for […]

Dear Mark: O6:O3 Ratio, Green Drinks, and Shin Splints

It’s Monday, and that means it’s time for another series of Dear Mark questions and answers. I think you’ll find today’s choices pretty interesting. First, I field a question from an apparently healthy reader who’s doing everything right, losing weight, and controlling the quality of his fat intake – but he can’t seem to avoid […]
