A Visual Guide to Sea Vegetables

About 160,000 years ago the human diet expanded to include seafood. Early humans became coastal dwellers at least that long ago, and ever since then we’ve been inextricably linked to the sea. The sea contains our most reliable source (when we aren’t dining on the brains of ruminants) of the all-important, long-chain omega-3 fatty acids. […]

Further Adventures with Leptin

I mentioned a few of the working hypotheses for avoiding leptin resistance in my posts last week, including fructose and lectin avoidance, getting adequate nightly sleep, and eating at or above maintenance levels – or at least throwing in periodic carb refeeds – but there’s even more involved in establishing a good relationship with your […]

The Lowdown On Lectins

Little known to the public at large. Little understood by the health community. Omnipresent in our conventional food culture. Proven to be at least mildly detrimental for everyone and downright destructive for the more sensitive (and often unsuspecting) among us. We’re talking lectins today: common natural agents on the one hand, cloaked thugs of the […]

Smart Spice: Turmeric

It may not share cinnamon’s universal applicability to consumables, but turmeric is another spice with some powerful culinary and medicinal qualities that deserves our attention. Turmeric, known officially as Curcuma longa and historically as Indian saffron, is a rhizome of the ginger family. Its horizontal root system is dug up, baked, and ground into a […]

Smart Spice: Cinnamon

We mostly see them as flavorants, as the little jars of powder that line our cabinets and the bags of dried roots, barks, and leaves tucked away in drawers, designed to subtly or drastically alter the flavor profile of our “smart fuel” creations in the kitchen, but for most of human history, spices were also […]

A Primal Primer: Prebiotics

Probiotics get a ton of positive press from a multitude of sources (including here). It’s one of those areas of nutrition that receives approval from pretty much every camp out there, like fish oil. (Even Dean Ornish supports the usage of fish oil; just about the only type of fat he seems to approve of.) […]

What’s Up With Your Gut? – Beneficial Bacteria and Good Digestive Health

Everyone knows (well, not everyone, but anyone who’s probably reading this) how crucial the early days of an infant’s life are for establishing good habits and healthy patterns for the rest of its life. What the mother eats while pregnant, what the child eats, delivery methods, breastfeeding duration, heck, whether you read to your children […]

Cooking with Bones

Marrow is great and all, but what about the bones that aren’t blessed enough to bear the sacred gel in easily extractable amounts? We can’t forget about those. Chicken backs, beef knuckles, ham hocks, chicken feet, lamb necks, hooves and any other animal-derived matrices of calcium phosphate and collagen fibers are all worth saving, cooking, […]

A Quick Guide to Bacon

Thin, thick, smoky, salty, hearty, meaty, maple, chewy or crispy. Different strokes, as they say. Nonetheless, you’d be hard pressed to find anyone – especially a Primal type – who doesn’t sing bacon’s praises. (Too bad so many CW followers eschew this fine delicacy.) Nonetheless, I wanted to address some questions dangling out there in […]

Seasonality, Climate and Diet

Evolution and seasonality are inextricably intertwined. This isn’t a negotiable, controversial statement, because evolution describes an organism’s response to environmental pressures, and the seasons are part of the environment. Another uncontroversial statement is that the study of human evolution can give us insight into what constitutes a healthy lifestyle for modern humans. I think it’s […]

Bone Marrow: Delicious, Nutritious and Underappreciated

If you’re truly interested in consuming the original Primal brain food, look no further than bone marrow: perhaps the first reliable source of large, fatty animal products our scrappy ancestors were able to procure. Yes, before we became spear-using cunning tacticians surrounding, stalking, and out-maneuvering large prehistoric ungulates, we feasted on the bones of fallen […]

How Much is Too Much? – Round 2

Last week’s post covering upper recommendations garnered so much interest – and additional questions – that I thought we’d give it another go around. While last week’s list took on basics like protein and fat as well as worthy indulgences like chocolate and – drum roll, please –BACON (break for rampant applause), this week I’ll […]

Seasonality for the Birds

Last week, we determined a common thread of seasonality running through historical fructose consumption. Warm weather with plenty of sunshine generally meant fruit was available. Those living in the tropics (as we humans did for most of our history) thus had year-round access to sweet fruit, while cold climate Grok had seasonal, intermittent access. Plus, […]

The Question of Seasonality in Fructose Availability

Let’s continue the discussion from last time. Again, I apologize for any meandering. This is a big topic, and I think it helps to leave no stone unturned. Seasonal eating is currently pretty popular, perhaps even trendy in some circles. You’ve got the locavores, folks who only dine on meat and produce grown and harvested […]

Dear Mark: Nuts and Omega-6s

Nuts have gotten a surprising amount of flack as of late. Many nuts have a fairly high PUFA content, and most of that PUFA is Omega-6, which is the bad one. It’s easily oxidized, highly unstable for cooking, usually rancid on the shelf, and, thanks to government farm subsidies and public hysteria over animal fat, […]

Dear Mark: Raw Eggs

A glassful of raw eggs incites mixed reactions for many of us. It’s routine for some and revulsion for others. Commonly associated with bodybuilders and boxers (the Rocky scene) who want to bulk up, a lot of folks who fit neither category include them on a regular basis for simple nutritional reasons. However, there’s more […]

A Primal Primer: Whey Protein

We’re long overdue for a good, solid post on whey protein. I include it in my Primal Fuel shake mix, a number of readers asked about it after last week’s dairy post, and it’s one of the more commonly used nutritional supplements around, so it’s a no-brainer of a post. What is Whey? Whey is […]

The Definitive Guide to Dairy

I knew going in this was going to be a tricky one, because dairy, especially raw and/or fermented full-fat dairy, resides in a Primal gray area. The literature, the evolutionary reasoning, and the anecdotal reports all unanimously point to sugar, cereal grains and legumes, processed foods, and industrial vegetable oils as being net negatives on […]

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 […]
