Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

Is Samwise Gamgee Right About Potatoes?

Potatoes are controversial in the Primal and paleo world. They represent a bolus of dietary starch, which can wreak havoc on the insulin resistant, but they are undeniably whole, real foods that don’t require much processing beyond simple heating. Grains and legumes, on the other hand, are tiny, disparate sources of calories that need soaking, fermenting, and extensive heating to be palatable (and they’ll still mess you up), but potatoes are big, dense, and obviously food. Chimps have been known to use sticks to dig up and eat wild tubers, and they’ve got even less salivary amylase to break down starch than we do. Evidence exists for human consumption of roots and tubers from multiple sites spanning multiple time periods: Northern Europe (specifically Poland), in the terminal Paleolithic and early Mesolithic. Clearly, we have the physiology (amylase production, glucose metabolism), the tools (fire, hearths, digging implements), and the motivation (attraction to dense caloric sources with negligible or easily neutralized anti-nutrients) to consume starchy tubers.

So what’s the hold up? Why do I generally recommend limiting their intake?

Weekend Link Love – Edition 114

To all the folks who found my free Grok tattoo offer on the final contest post of the 30 Day Challenge, your tats are in the mail! And speaking of which, it’s not too late to enter that last contest, but do it fast.

Cheers to reader Eric for finding this gem (PDF) in the Nutrition Journal that (Eric’s colorful words) “fully b****-slaps the American Dietary Guidelines for being based on faulty science, weak evidence, and weak results.”

In the three decades since, carbohydrate consumption has increased; overall fat, saturated fat, and cholesterol consumption have decreased to near or below targeted levels; caloric intake remains within recommended levels; and leisure-time physical activity has increased slightly (pp. D1-1, D3-10, B2-3). At the same time, scientific evidence in favor of these recommendations remains inconclusive, and we must consider the possibility that the “potential for harmful effects” has in fact been realized. Notably, “the prevalence of overweight and obesity in the US has increased dramatically in the past three decades” (A4); the number of Americans diagnosed with T2D has tripled.

Warning, the following article is hard to read, the title explains why: Family Farm Ordered to Destroy 50,000 Pounds of Cheese.

Lobster, Grapefruit and Avocado Salad with Creamy Citrus Dressing

When you’re in the mood for something decadent, or a special occasion arises, or it’s a Tuesday and for no particular reason at all you’re craving lobster, MDA Reader Kerry Carlson’s Lobster, Grapefruit and Avocado Salad with Creamy Citrus Dressing is one to turn to.

Kerry’s lobster salad is flavored by a bold combination of tart grapefruit, creamy avocado and salty bacon. This trio of contrasting flavors will wake up your taste buds and demand they take notice of what you’ re eating. Each bite is a celebration of varying textures and flavors, and when one of those bites also includes a chunky piece of lobster meat, you’re really in for a treat.

Medical T.V. Is Bad For Your Health

Despite our culture’s “problematic” relationship with personal health (yes, I’m straining to be this diplomatic), we sure do like our medical T.V. There’s the news of course, the doctor talk shows, and the dramas: House, HawthoRNe, Grey’s Anatomy, Private Practice… (I have no doubt I’m missing some.) It’s one of those head scratchers – kind of like our culture’s current penchant for food T.V even though the average American spends less time cooking than ever these days. When it comes to the news, they make anything and everything sound like an imminent emergency. (Swine flu, anyone?) As for the dramas, there are the good looking people, romantic plotlines, feverish action, and tear-jerking narratives. More to the point, however, you have bizarre assortments of random medical oddities, the suspense leading up to the eventual diagnoses, and the inevitable drama surrounding characters’ medical treatments and tragedies. It’s enough to pique anyone’s curiosity, but some interesting research shows that we’re getting more than we bargained for from our entertainment.

Empowering Poses

I’m not big on yoga, as most of you know. Too much idle time for me. I’d rather be playing. But last Sunday (a beautiful, sunny, SUP kinda day), I caved to the pressures of my wife Carrie, who loves yoga, and attended a session. It was to be a multi-hour event (a “workshop”) so we brought pillows and fur blankets to be comfortable. As we’re entering the studio, bedding in tow, I run into Michael Anderson, the owner of CrossFit Malibu sitting in the atrium, sipping on a Starbucks coffee. I must have looked like a deer caught in headlights and he just grinned. Mark Sisson, Mr. Primal, with a furry blanket and just moments from striking a pose and singing some oms. I told him that nothing was going on here, mumbled something about research and that he hadn’t seen anything. We winked and went our separate ways. I kid, of course, but there might be something to this after all.
