5 Obscure Nutrients: Why We Need Them and How Grok Got Them

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?

A Primal Look at Skin Care

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?

Let’s discuss….

Dear Mark: Fasting Followup

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.

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?

Where Do Legumes Belong in the Primal Eating Plan?

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).

Dear Mark: When Walking Is No Longer Enough; Fermented Foods and Depression

For today’s edition of Dear Mark, I’m answering two questions. First up, what happens when a brisk walk isn’t enough to attain the optimal fat-burning heart rate zone? It’s a good problem to have—better fitness—but it still needs a response. What activities can a person do to slightly increase the intensity without going over the target heart rate? And second, are fermented foods a potential cause of depression? If they have any effect on serotonin, could this cause problems rather than improvements?
Let’s go:
