As children, we live closer to our instincts. Yes, there’s the humorous and rather unfortunate side to this – like the time you ate an entire bag of Twizzlers and threw up all over your great-aunt’s carpet. In addition to the plethora of bad decisions (as if adults don’t make those too), however, there’s the extravagant daring and that amazing, irrepressible exuberance.
As adults, we might know better than to gorge on dye #40, but we’re tripped up by other things. We become distanced, detached from our instincts. The responsibilities, the schedule, the expectations surrounding our culture’s take on maturity can cast us out of the land of exuberance. It’s like we get gradually diverted to a boring Interstate stretch after traveling the scenic route. The road is efficient, utilitarian and might have nicer rest stops, but it often feels like a major letdown. What does it take to find our way back to the panoramas? What are the things we never should’ve stopped doing in the first place? I hope you add your own to the list. Let me throw out a few I’ve been thinking of today.
For years now, it’s been said that telomeres – the tips of your chromosomes – are the key to cancer and aging. The shorter they are, the worse off you are – so the story goes. But what do we really know about them? Can the length of your telomeres help predict how long you’ll live? Could telomere research unlock a modern fountain of youth? Could humans one day live to be hundreds of years old?
Dr. Ron Rosedale of DrRosedale.com and The Rosedale Diet is here to answer some of these questions in this special guest post. In it he will introduce you to these little bits of genetic sequences, and provide his expert commentary on the state of telomere science. It will get somewhat technical in parts, but it’s well worth the read.
Now, Dr. Rosedale…
Vegetables can be hard enough to work into our diet without other factors making it even more difficult. Either we’re stuck with nutrient-sparse, weeks-old produce that has lost all semblance of flavor (but it’s certainly affordable!), or we’re inundated with a countertop full of beautiful vegetation straight from the farmers’ market that we can’t hope to consume in time. You think convincing a ten year old to eat a plate of fresh sauteed kale is hard? Try getting a ten year old to eat a plate of sauteed withered kale that’s been sitting in the fridge for a week. And what about cooked vegetables versus raw? Some say that raw produce is the only way to eat it, that if you cook a carrot you’re rendering its nutritional content null and void. Is it really that dire? Does it matter that much? Find out the answers to these questions, plus one on whether or not copper deficiency can trigger premature gray hairs, in this week’s edition of Dear Mark.
Pretty much every feature of the human body can be found, in some form or another, on other species. Opposable thumbs? Great for building and using tools, but apes have them, too. Even the giant panda has an opposable sesamoid bone that works like a thumb. Bipedalism? Helped us avoid direct mid-afternoon sun and carry objects while moving around the environment (among other possible benefits), but plenty of other creatures walk upright, like birds and Bigfoot. The human foot? Okay, our feet are quite unique, but every other -ped has feet (just different types), and they all work well for getting around. So, what is it that makes us so different from other animals (because it’s got to be something)?
A time-honored and research-tested way to extend an animal’s lifespan is to restrict its caloric intake. Studies repeatedly confirm that if, say, a lab mouse normally gets two full bowls of lab chow a day, limiting that mouse to one and a half bowls of lab chow a day will make that mouse live longer than the mouse eating the full two bowls. Cool, cool, a longer life is great and all, but what about the downsides of straight calorie restriction, aside from willfully restricting your food intake, ignoring hunger pangs, relegating yourself to feeling discontent with meals, and counting calories and macronutrients obsessively? Are there any others? Sure:
Loss of muscle mass. Humans undergoing calorie restriction often suffer loss of lean muscle mass and strength, all pretty objectively negative effects (unless you really go for the gaunt “Christian Bale in The Machinist” look and use a super-strong bionic exoskeleton for all your physical tasks).
We in the Primal community talk a lot about the modern medical situation – the growing prevalence of lifestyle disease and the misguided, costly paths conventional health wisdom too often prescribes. Still, some conditions seem less – well, conditional – than others. Take eyesight, for example. If we wear glasses or contacts, we look to our families or age. While genetics and years certainly have their influence, is that the entire story for everyone? Is vision a wholly “closed” process – set in motion and then untouched by overall health and physiologic interaction, or is it more dynamic and systemic than that?
I get a fair number of emails from folks who wonder about their eye health in a Primal context. A while back I looked at the potential role of sunlight in preventing myopia, but that was just the tip of the iceberg. The post got people thinking. What are the other factors and theories behind the myopia surge? And as for readers’ individual circumstances, were they really destined to wear glasses? Is there anything they can do once they’re already living with a vision prescription? Glasses or no, what can we do to support the well-being of our eyes throughout our lifetimes?
Height has historically been regarded as a marker of health and robustness. We seem to implicitly accept that bigger is indeed better, even if we don’t want to admit it. On average, tall people attain more professional success and make more money, the taller presidential candidate almost always wins, and women are more attracted to tall men. On a very visceral level, the taller person is more physically imposing. After all, who would you rather fight – the dude with a long reach raining punches from up high or the shorter guy with stubby arms who has to work his way inside your guard (although Mike Tyson did pretty well for himself with such “limitations”)? And on that note, who would you prefer as a mate – the physically imposing specimen or the shorter, presumably weaker male?
We in the Primal health community are quick to point out that agriculture reduced physical stature. Generally speaking, bone records indicate that Paleolithic (and, to a lesser extent, Mesolithic) humans were taller than humans living immediately after the advent of agriculture. Multiple sources exist, so let’s take a look at a couple of them before moving on:
Everyone ready for the holiday weekend yet? It’s a good time, I think, to cover a relaxing, if not inspiring, topic I’ve been meaning to get to. In all seriousness, I get a couple emails every week from folks who are wondering about their waxing or waning sexual drive and how it relates to their lifestyle. Some are folks celebrating the return of their mojo after losing weight and and gaining energy on the Primal Blueprint. Others are from readers concerned about their partners’ unhealthy habits and what they see as the coital repercussions. Still more are from folks transitioning to Primal living and going through a period of energy “adjustment” as they find the right balance in their workout regimens, calorie intakes, and overall lifestyle picture. In all, the questions revolve around a central point: what lifestyle measures support optimum sexual drive?
Hi folks! I’m Emily Deans, M.D., a psychiatrist who normally blogs over at Evolutionary Psychiatry and at Psychology Today. However, Mark Sisson was kind enough to ask me to do a guest blog for Mark’s Daily Apple, and of course I am thrilled to oblige. My main interest is to explore how the differences in our modern lives and diets compared to a traditional/evolutionary experience may influence how our brains work and leave us more vulnerable to mental illness. If modern diets and lifestyle do leave us ragged in brain as well as body, The Primal Blueprint, being a practical diet and lifestyle that specifically emulates evolutionary conditions, would then theoretically be part of an antidote to modern mental health problems.

Got your attention? (Thought so.) Sisson’s gone morbid, you say. Not exactly. Death is on the docket for today but more so the time leading up to death – (for some) a period of morbidity during which we experience major illness and impairment. We live, of course, with the prospect of our own mortality and how it will befall us, but we’re also emotional witnesses to that of our loved ones. I’ve lost many family and friends at this point in my life. Although I believe most had a good life, not many had what any of us would consider a “good death.”
