Artificial Sweeteners May Leave You Absolutely Gutted

Several years ago, I covered the popular artificial sweeteners sucralose, acesulfame-k, aspartame, and saccharin, finding mixed results and little to confirm the widely-held view that they provoke an insulin response. I also wrote about diet soda in general, coming out generally against them while acknowledging the lack of hard evidence either way. But artificial sweeteners […]

Dear Mark: Leg Fatigue, Too Much Muscle Meat, Starch Persorption, and Hadza Study Author Responds

For today’s edition of Dear Mark, we’ve got four questions. First is a question from a reader who exemplifies the “between a rock and a hard place” situation inherent to chronic cardio. Second, I address a reader who worries that I’m not worried enough about exclusive muscle meat consumption. Third, I give my thoughts on whether […]

Does Red Meat Clog Your Arteries After All?

I’ve been asked to comment on the latest media deluge to suggest that red meat is again the primary cause of atherosclerosis, heart disease, and your impending doom. At least this time they’re targeting something other than cholesterol: this time it’s carnitine. Carnitine is found in red meat, mostly, as well as dairy, tempeh, and […]

How Simplifying Your Life Can Help You Refocus on What’s Important

Earlier this week I ran across a study that demonstrated a “simple lifestyle” can decrease our contact with toxic endocrine disrupting chemicals. The researchers looked at lifestyle elements like transportation, personal care products, and homegrown versus purchased food in their participants. I was struck by the study’s suggestion itself but also by the larger metaphoric […]

Dear Mark: Is Meat Going to Kill Me (Again)?

There’s another “meat is bad” study making the rounds, featuring such stellar prose as: “Although causality cannot be established…” “…further research is recommended.” “…should still strive to reduce intake of red and processed meat, which tend to contain high amounts of saturated fat and sodium.” And so on. By now, we see these lines, roll […]

A Different Kind of Fitness Resolution

It’s the month when gym memberships spike and fitness equipment flies off store shelves. I think most of us begin the year wanting to be healthier, and fitness stands as an essential element of that endeavor. Logical. Reasonable. Commendable. Yet, the common interpretation of what it will take to get there suddenly veers off in […]

Should We Ice Injuries?

I’ve said this before, but inflammation is a necessary response to injury. It’s the inflammatory response that increases blood and lymphatic flow to and from the injured tissues, bringing healing nutrients and inflammatory mediators and removing damaged refuse. It’s the inflammatory response that makes injuries hurt, which prevents us from using and re-injuring the injured area. […]

Is Organic a Scam? – Nutrient Differences

Even if you can get folks to begrudgingly admit that organic foods tends to contain fewer pesticide residues than conventional (and that this might even impact a person’s health or the way a child develops), they’ll dig in their heels when it comes to the nutritional content. And why shouldn’t they? Organic isn’t really about […]

Is Organic a Scam? – Fetal and Child Development and Antibiotic Resistance

A few weeks ago in Weekend Link Love, I mentioned the great big much-ballyhooed study that appeared to show organic produce was no more healthy than conventional produce. Many people with an axe to grind championed its findings, with some proclaiming the undeniable ringing of the final death knell of organic farming. Science Based Medicine […]

Autism: A Brain or Whole-Body Disorder?

You could say this post is a long time coming. In the last few years, I’ve lost count of the huge number of emails I get from parents with kids who have special needs either asking for advice or explaining how The Primal Blueprint has made a significant difference for their children. These are parents […]

Dear Mark: Fat Triggers Marijuana-Like Chemicals, Another Anti-Meat Report, and Teff

How was the weekend for you? Mine was kinda tough. Great weather beckoned all weekend, and my paddleboard and I shared mournful glances full of longing, but I was stuck inside working on my talk for the upcoming Ancestral Health Symposium at UCLA. I think it’s going to be a good one, though, so hopefully […]

The Art of Work: Avoiding the Pitfalls of a Sedentary Job

A series of recent studies have implicated sedentary lifestyle in the obesity epidemic. The idea is, even if you hit the gym a few times a week, parking it in front of the T.V. at night dwindles away any benefits gained. Every hour on the couch costs us dearly. But what about the office chair? […]

Dear Mark: Soy Lecithin, Healthy Fat Alternatives, Wasted Workouts, and Magic Grapefruit

Things got a little heated regarding the milligrams of evil soy lecithin used as in emulsifier in most dark chocolates in last week’s Dear Mark post, so before launching into today’s questions and answers, let’s go over that. Soy lecithin is simply the byproduct of soy oil extraction. It’s not hydrogenated soybean oil, folks allergic […]
