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...

Dear Mark: Roundup Safety and Polyamory to Monogamy

For today’s edition of Dear Mark, I’m covering two entirely different topics. The first is a fairly familiar topic to readers of this blog—whether a popular pesticide is actually dangerous or not. The reader asking the question thinks the data is clear, and Roundup is safe, but I’m not so sure. Second, I discuss the evolutionary underpinnings of our transition from polyamory to monogamy.

7 Reasons to Love Wheat

Wheat gets a bad rap in the alternative health sphere, receiving blame from all sides. Today, I’m here to provide the other side. Today, I’m going to give you seven solid reasons to love wheat, ranging from its effects on the environment, its role in the foundation of the American republic, its effect on gut bacteria and your health, its ability to stamp out hatred, its protective role in the lives of Bronze Age Chinese women, and its status as an enduring symbol of human rights and prosperity.

Let’s get right to it.

Dear Mark: Erythritol and Weight Gain, Chicken Liver and Arsenic, and Tips for Laptops in the Sun

For today’s edition of Dear Mark, I’m answering three questions from readers. First, is erythritol, one of the more common sugar alcohols, linked to weight gain? According to a new study, it is. What should we make of the research? Next, I talk a good game about chicken livers, but there’s a new study that seems to show they’re big repositories of arsenic. Should you stop eating chicken liver? And finally, I give a few tips for improving screen clarity when working outside on your laptop in full sun.

Dear Mark: Superfoods, Plants for Pollution, Raw Liver Danger, and Irradiated ‘tsticles

For today’s edition of Dear Mark, I’m addressing four questions and comments from readers. First up, do I subscribe to the idea of superfoods? If so, what do I like? If no, what do I consider “super”? Next, we know that plants—house plants, garden plants, trees—can absorb pollution and release stress-lowering odors. Is there an optimal arrangement of flora to achieve these goals? After that, I address a reader comment about the dangers of eating raw liver, followed by an intrepid reader who found the reference for the sunbathing testicle study from last week.

How to Augment and Support Your Natural Detox Capacities

Conventional wisdom has decreed that “detox” is a myth. They’re not even sure if toxins even exist, as far as I can tell. On the other side, you’ve got detox gurus prescribing cayenne-maple-lemon tea and glasses full of charcoal water as cures for essentially everything. Where’s the truth lie?

First, detoxification does exist. It’s an established concept, after all, with its very own spot in the dictionary. When we come into contact with toxins—compounds that pose a threat to our healthy homeostasis—we must remove or nullify them. That’s detoxification.

Dear Mark: Raw Mushrooms, Tom Brady’s Diet, and Beta-Glucan Alternatives

For today’s edition of Dear Mark, I’m answering three questions. First, are raw mushrooms safe to eat? Are there toxins? Are there any other issues to consider? Second, what’s the deal with Tom Brady’s diet and lifestyle? It seems healthy enough, but there are some unanswered questions, too. And finally, are there any other ways to get beta-glucans without eating mushrooms, yeast, or oats?

19 Personal Care Products I Use or Like

A few years ago, I wrote a long post listing cosmetics, soaps, and other personal products made with healthy, non-toxic ingredients. It’s a sad thing when you basically have to assume the worst about the average product designed to be slathered all over the largest organ of your body—your skin. But that’s the situation in which we find ourselves now.

Today’s post is an update of sorts. What products am I using? Which ones have I used? And are there any others that I can safely recommend? It won’t be as comprehensive as the last one. It will be more personal.

How to Buy (and Appreciate) Eggs

Time and again I find myself on the topic of eggs. I’m a fan really. In fact, I had them for breakfast just this morning (as most mornings).

They’re one of nature’s true superfoods after all—pre-packaged and ready to enjoy however you see fit. The healthy fats, proteins, vitamins and minerals contained within simply can’t be ignored, regardless of all those misguided cholesterol-haters out there.

Back in 2008, I provided a brief look into deconstructing egg carton labelling. That simple guide to egg purchasing has gotten a fair amount of attention and shares over the years, so I’m revisiting the subject to update and elaborate where it makes sense. I don’t see eggs ever losing their place in paleo/Primal eating, and I know others share my enthusiasm.

Dear Mark: Infrared Sauna Roundup

After last week’s post on infrared saunas, people asked some good questions. For today’s edition of Dear Mark, I’m answering a few of them. First up, can infrared saunas harm male fertility? After all, they do penetrate the skin and raise body temperature, which is a no-no for sperm. Next, infrared saunas induce lots of sweating, and sweat contains bioaccumulated toxins like BPA and heavy metals. Can infrared saunas help us shed these toxins? Finally, are infrared-emitting blankets and other “topical” infrared products effective alternatives to infrared saunas?

Some Primal Answers for Kids’ Problem Behaviors

Last week, Chris Kresser wrote a great article discussing the emerging—and likely causative—link between poor gut health and childhood misbehavior. He explained potential mechanisms for the association, as well as solutions to counter it.

But as any parent knows, getting a picky child to adopt your arsenal of perfect gut-supporting foods and supplements isn’t always easy. Not every kid immersed in the righteous anger of the terrible twos will stop what he’s doing to drink sauerkraut juice, nibble on kimchi, take resistant starch, drink kefir and bone broth.. It’s certainly a major part of the problem and the solution, but are there any other dietary causes? What else can a parent try to stem the flood of tantrums?
