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...

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?

A Primal New Year’s Eve Survival Guide

New Year’s Eve approaches. Parties beckon. Arsenals of alcohol accumulate. Whether you venture out into the wild night or keep it quiet with close friends and loved ones (that’s me), people will probably offer you a glass (or several) of something containing ethanol to mark the occasion. As always, it’s not about a right or wrong choice but about assuming responsibility for your health. I’ve heard a lot of readers over the years say going Primal has made them much more sensitive to the effects of alcohol. If you’ll be partaking, you can gird your system to deal with the incoming toxicity.

Dear Mark: Fruit Wax, Placentophagy, and Second Hand Smoke

For today’s edition of Dear Mark, I’ll be covering several topics. First, I cover fruit wax, that lovely layer of ultra-thin sheen applied to many fruits and vegetables in the grocery store. Is it harmful or innocuous? Find out below. Next up is one that makes most people extremely squeamish: placentophagy, or the consumption of the placenta by the mother following birth. Does it do anything? Should people do it? What’s the deal with it? Finally, I field a question from a guy who hangs out in a bar for a few hours a week with his friends. All good, right? Unfortunately, this particular bar allows smoking, so he’s wondering whether or not he’s doing any real damage to himself from exposure to second hand smoke.

Dear Mark: Acrylamide, Sprint Alternatives, Gynoid Fat, and Adult Bed Sharing

In this week’s edition of Dear Mark, I’ll be covering three wide-ranging topics. First is acrylamide, the french fry toxin, the coffee carcinogen, the rat destroyer. It appears in almost every starchy item cooked or roasted at high heat, and it’s classified as a carcinogen. What do we do about it? Do we even have to worry about it? Next up are sprint alternatives for the person who loves to runny really fast every once in awhile but has a herniated disk that becomes aggravated shortly after said sprint. Sprinting is an important, beneficial activity, so long as you can do it pain and injury free, so I try to come up with a few worthy options. Then, I offer some advice to a man with gynoid – or lower body/hip/thigh – fat, most of which hinge on my suspicion that he’s low in free testosterone. Finally, I discuss the benefits – and drawbacks – of co-sleeping with your adult partner.

7 Foods You Don’t Need to Buy Organic

A couple weeks ago, I gave you a list of the top 10 foods you should strive to buy organic. Some of you found the list useful, while others felt a bit overwhelmed and disheartened by the information, saying that it felt like they couldn’t eat anything that wasn’t organic. Today, I’ll try to make things a little better by giving you a list of the foods which are perfectly fine in their conventional form. However, even if the following conventional foods are relatively safe for your health, some would argue that you should still buy organic in order to support the workers and protect the environments exposed to agricultural chemicals. That’s totally valid, and it’s part of the reason why I try to buy organic, but it’s not what I’m discussing here. It’s a topic for another time. Today is about maximizing the health of you and your family while cutting costs when and where you can.

So, what common, Primal staples can you buy conventional?

Dear Mark: Preservatives in Lard, Ace-K, Raspberry Gorging, and Veal

What would you do if someone gifted you with a 5-pound tub of lard? Jump for joy? Grab a spoon? All reasonable responses, but what if that tub of lard had a label that said “contains BHA and BHT”, two antioxidants commonly used to preserve processed food, cosmetics, and pharmaceuticals – how would you react? That’s the first question I tackle in today’s edition of Dear Mark. After, I discuss whether or not acesulfame potassium, an artificial sweetener, is safe to consume, whether Joe should venture into the creepy raspberry forest threatening to overtake his house, and how organic dairies handle their male calves.

Ready? Let’s get to it:

Dear Mark: Swimming Pool Chemicals, Washing Veggies, and Carb Blockers

Who doesn’t like a lovely day at the pool? Unless you can’t swim, there’s no reason not to love the cool water, the bright sun, the ping pong (every swimming club worth a dime has a ping pong table, or several of them), the face dunking, the high dive, and the chicken fights. But what if something sinister churned within the depths of the chlorinated water? What if by entering that pool you were risking life, limb, and the pristine alabaster of your eyeball? In today’s edition of Dear Mark, I’ve gone back to the roundup format. I begin with the question of swimming pool chemical safety, follow with a query about washing vegetables, and I finish the post with a short section on carb blocking agents. Sound good?
