Gut Flora and Your Healthy Immune System

Last week, I discussed the importance of gut flora in the digestion of food while briefly touching on its role in early immunity, including the development of asthma and eczema – both of which are immune issues that appear to be exacerbated or caused by disrupted gut flora in children. But it goes much further […]

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 […]

Dear Mark: Sugar as Immune Suppressant

Dear Mark, Since going Primal last summer, my vegan buddy and I have some very explicit differences of opinion. I’m sure you can guess where they come up. Where we agree though is on the subject of sugar, especially refined sugar (syrups, honey, HFCS, table sugar, etc). Neither of us eat the stuff as a […]

Are Humans Hard Wired For A Limited Social Circle?

Despite growing insight into neuroscience and the physical limitations of our consciousness, we have the tendency to ascribe a limitlessness to our minds. We readily accept the existence of certain boundaries in the material world, like fences, social stations, rules, laws (of physics and of states), or physical characteristics (“You must be this tall to […]

How Light Affects Our Sleep

Most people are at least cursorily familiar with the concept of the circadian rhythm. For those who aren’t, the circadian rhythm refers to our internal, approximately 24-hour cycle of biochemical, physiological, and behavioral processes. Every living thing, from fungus to bacteria to plant to animal, has a circadian rhythm. External cues called zeitgebers (what a […]

Dear Mark: Embodied Cognition

The following reader email brought to mind a NY Times article I read a few weeks ago. The article discusses a fairly new field of research that is uncovering the surprisingly fundamental and intricate ways our bodies influence our thinking and vice-versa. We’ve discussed the mind-body connection in the past, but embodied cognition puts the […]

Weight Loss Shortcuts: Pills, Suction and Now… Lasers

Imagine a world where you could stroll into a clinic, spend fifteen minutes reading a magazine while a doctor’s assistant points a bizarre contraption at your backside, and skip out the door, down a few thousand bucks and twenty pounds lighter. Provided you had the money and the extra weight, would you do it? Would […]

A Sea Change Coming to Wash Your Shoes Away

I’m sure you’ve seen it. It’s all over the news. People are finally beginning to come around to that inconvenient truth about our feet, that dirty little secret that shoe companies would prefer to keep under wraps: barefoot is better. There has been media coverage of the barefoot trend in the past, mostly intermittent, in […]

GMOs: Safe for Consumption?

We’ve examined the arguments for and against GMOs in the past. Indeed, there are reasonable and valid points to be made on both sides of the issue. Nonetheless, we concluded that there are just too many red flags to support the industry’s direction in GM technology. Not only do GMOs drive the use of naturally […]

To Circumcise or Not To Circumcise?

Once a proverbial given in this and a number of other countries, circumcision has become a hot button issue, intensely debated in both family and medical circles. For decades it was standard procedure for hospital births, but the numbers are quickly declining. Today, 56% of newborn boys are circumcised, although the rate varies considerably by […]

Assessing Sanitizers: Cleaning Up the Confusion

If you believe the ads, we live in a squalid hotbed of menacing microbes. Evil germs are everywhere and out to get us – especially the innocent, well-dressed children playing nearby. The smart ones among us, the marketers tell us, navigate this ominous world armed with the right sanitizing defense. Even the grimiest restroom, 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 […]

Benefits of Benevolence

It’s a message fitting for the season and one that gives a whole new meaning to the adage, to give is to receive. Acts of generosity, research shows, don’t just lead to emotional satisfaction; they actually promote physical health and healing. It’s more than good karma of course. There’s evolutionary rationale to the warm fuzzies […]

Cell Phone Health Hazard?

It’s become one of those oft-repeated half-truths floating around that people either assume to be unerringly true or completely false. It draws both sides of the spectrum: those that eschew all traditional medicine, and the folks who take the official governmental recommendations and proclamations as gospel, every single time. Every now and then, you might […]

Dear Mark: Feast or Famine Diet?

Among the questions I get from MDA readers are those that ask about timely diet trends – you know, the latest regimens highlighted in the media or promoted by high profile stars and athletes. Some are bookstore blockbuster plans like The Zone, while others are the latest celebrity diet du jour. As my wife and […]

Coca-Cola Cares About Your Health

It’s the stuff of quintessential irony. Paradox. An absurdity so egregious it’s painful to type, let alone view on the screen. (There’s actual smoke rising from my keyboard….) We’re talking corporate “public health” sponsorships so ridiculous your eyes will fall out of your head. First, a show of hands. How many of you are familiar […]

The Biggest Loser… Is the Audience

I watched The Biggest Loser last week – as well as the prior week’s opener, thanks to TiVo. I know what you’re thinking, but, hey, it’s my job and it has to be done. Truth is, I figure it’s about time someone shook America by the lapels and exposed the myths and fallacies in this […]

Weighing the Evidence: Science and Anecdote in Nutrition Studies

I was a science major (biology) in college, yet I have always been a little suspicious of the use of the “scientific method” when it comes to biological systems – especially humans. I guess it started when we were all taught in labs as far back as high school to strictly adhere to the scientific […]

The Age of Antidepressants?

Now that we’ve turned the page on August’s Primal Challenge, we’re digging into some of our “regular programming,” including news highlights. We like keeping a finger on what’s new and novel – and occasionally outrageous. This one definitely fits the latter. (Hint: Are you sitting?) A few weeks ago the Archives of General Psychiatry reported […]
