For today’s edition of Dear Mark, I’m answering just one question. But it’s a good (well, maybe not good, but certainly important) one: Why is male fertility on the rise and testosterone on the wane? The popular notion is that women flushing birth control pills and peeing estrogen-rich urine into the public water supply are the primary reasons for the sex hormone issues facing men, but I’m not so sure. Let’s explore what else might be causing the problem.
Read MoreFor 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.
Let’s go:
Read MoreFor today’s edition of Dear Mark, I’m answering five questions from readers. First up, why isn’t hiking giving one reader the shifts in body comp they expected? Two, is there actually a way to mask the flavor of liver? Then I discuss a few unconventional testosterone boosters, followed by a brief treatment of the cooked, then cooled, then reheated potato. And finally, are there any dietary activators of sirtuin proteins?
Let’s go:
Read MoreBy 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….
Read MoreFor today’s edition of Dear Mark, I’m answering two questions. First up concerns the effect going Primal has on your skin’s resistance to sun damage. While there isn’t any specific research examining ancestral eating and sun damage, several lines of evidence suggest a protective effect. Second, what’s the deal with stigmasterol, AKA Wulzen anti-stiffness factor? The WAPF says butter and cheese and milk are the best place to get it, but that pasteurization destroys it. Is this really true? And how does fermentation affect stigmasterol?
Let’s go:
Read MoreMost of us go Primal to solve problems created by Conventional Wisdom. The importance of whole grains and daily cardio, the dangers of dietary fat and animal protein, the primacy of carbohydrates for “energy,”—these untruths are promulgated so widely and fail so conclusively that you can’t help but look to the people saying the opposite for direction. That’s where we come in. Most of us go Primal to solve problems created by conventional dietary and lifestyle recommendations. Often these solutions involve doing the opposite of what the authorities are telling us. For the most part, it works.
Sometimes eschewing conventional advice goes too far, though. Sometimes we make serious blunders in our pursuit of Primal perfection.
