The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate...
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...Tell Me More
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.
Everyone reading this knows about the macronutrients. You’re all eating enough protein, fat, carbs, and the various sub-categories, like fiber, omega-3s, MUFAs, SFAs, linoleic acid, and so on. You know the major micronutrients, like magnesium, calcium, vitamin B12, and most of the minor (but still vital) ones, like plant polyphenols, iodine, and vitamin K2. Today I’ll be talking about the truly obscure nutrients. The ones health food hipsters were super into like, five years ago (“I’m taking beta-1,3-glucan, you probably haven’t heard of it, there’s only one group at Hokkaido University doing any research, you can only get it off the DarkNet using bitcoins”). The ones Grok was super into like, 50,000 years ago.
What are they, what do they do for us, and, if they’re so great, how did Grok obtain them?
By next year, Americans are expected to spend nearly 11 billion dollars on skin care annually. By some estimates anyway, the biggest share of this market goes to “anti-aging” products. Anti-aging… As I noted in an offhand way a few years back, there’s a certain enjoyment in looking good naked (or just looking good), and there’s nothing wrong with that. Looking “good” is largely a reflection of optimum inner health—nothing un-Primal about that. Great health is what we’re all here for. The “extra” rewards that come with it aren’t anything to shake a stick at—or to be sheepish about.
But the health ambition isn’t really what’s behind the statistics above. At their best, anti-aging products boost the body’s natural processes (or at least don’t undermine them with toxins). At their worst, these products promise a way to cheat effort as well as time. While taking care of your skin is part of basic hygiene, too often the claims have more in common with a hat trick than genuine wellness. But which is which?
For today’s edition of Dear Mark, I’m answering questions from the comment section of last week’s fasting post. You guys brought up some great points, and I’ll be addressing some of them. First up, do you need to follow a vegan diet to maintain the health benefits of long fasts? Second, I give a tip or two for appetite suppression during the fast. Then I discuss my definition of a long fast, the potential effect of fasting on gut bacteria (and whether we should consume prebiotics and probiotics while fasting), the reason why fasting makes some people have short fuses, and whether green tea k0mbucha breaks the fast.
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?
I never cared much for legumes growing up. Growing up, beans were the “magical (or musical) fruit that made you toot.” They existed in a quantum state: beans were your ally in schoolyard rear-facing attacks and your downfall during encounters with that pretty girl from history class. But the issues I had were mostly superficial. I’ve never come out strongly against legumes. My focus has always been on grain avoidance.
Way back, I placed beans and lentils and other legumes in the “Okay” category. If you wanted to eat them, and you had carb calories to spare, they were a decent choice. Flatulence aside, they are relatively nutritious and come with a big dose of prebiotic fiber for your gut flora (hence the gas).
