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
Earlier this week I ran across a study that demonstrated a “simple lifestyle” can decrease our contact with toxic endocrine disrupting chemicals. The researchers looked at lifestyle elements like transportation, personal care products, and homegrown versus purchased food in their participants. I was struck by the study’s suggestion itself but also by the larger metaphoric significance. A simpler code of life can spare us some of the inherent stress and damage of our modern lives. As this study showed, the principle certainly holds for physical health, and I easily venture it holds for mental well-being, too. Living simply offers a multi-layered protective benefit. That’s worth taking apart.
There’s another “meat is bad” study making the rounds, featuring such stellar prose as:
“Although causality cannot be established…”
“…further research is recommended.”
“…should still strive to reduce intake of red and processed meat, which tend to contain high amounts of saturated fat and sodium.”
And so on.
By now, we see these lines, roll our eyes, and keep on moving down the path that seems to be helping us. But that’s us, people who pay attention to nutrition news and stay abreast of the literature. We may be able to write off these breathless articles without thinking we’re going to die because we ate that bunless burger the other day, but our parents, our friends, our colleagues may not be so well-equipped. They’re worried about our health, and who can blame them? If you take mainstream health articles at face value, articles which confirm what your doctor is probably telling you, you would do the same.
It’s the month when gym memberships spike and fitness equipment flies off store shelves. I think most of us begin the year wanting to be healthier, and fitness stands as an essential element of that endeavor. Logical. Reasonable. Commendable. Yet, the common interpretation of what it will take to get there suddenly veers off in a white knuckle, nonsensical detour. Yes, let’s hear it for the chronic cardio model. As a former cardio king, I rack my brain questioning why so many people still subscribe to the “exhaustion or bust” mentality. (It’s unfortunately one of the reasons many said memberships will go unused by the middle of next month and the aforementioned equipment will begin gathering dust in a corner.) As with so many aspects of healthy living, the conventional fitness culture often misleads because it ignores what can and should be its ultimate guide – the nuanced role of physical activity in evolution and the simple but rather elegant connections that movement has to overall vitality.
Earlier this year, I explored the “evolution” of human dietary requirements in the last 10,000 years by examining some of the SNPs – single nucleotide polymorphisms, or variations in genetic sequences – that relate to diet and nutrition. I concluded that while certain genetic changes to the way we process certain foods have arisen in certain populations, for the most part we’re still best off eating from an ancestral, Primal spread of animals, sea creatures, and plant life. Nothing has changed on that front in my mind, but people are still understandably curious about their genetic predispositions toward various conditions, and, with the recent reduction in price for SNP sequencing from 23andMe (to $99 with no subscriptions required), as well as slightly more affordable full-on genome sequencing (~$1000) on the not so distant horizon, it’s easier than ever to actually do it.
But should you?
Even if you can get folks to begrudgingly admit that organic foods tends to contain fewer pesticide residues than conventional (and that this might even impact a person’s health or the way a child develops), they’ll dig in their heels when it comes to the nutritional content. And why shouldn’t they? Organic isn’t really about getting more vitamins, minerals, or other nutrients; it’s always been about getting vitamins, minerals, and other nutrients without the conventional pesticides, herbicides, and fungicides that so often accompany conventional produce. The presupposition that proponents of organic produce claim it contains more nutrients is a bit of a straw man, as that claim is rarely – if ever – made.
But what if that mythological claim actually held a kernel of truth? I mean, now that they’ve mentioned it and let that monkey out of its cage, let’s explore a bit to find out, starting with the Stanford study that sparked this whole topic.
A few weeks ago in Weekend Link Love, I mentioned the great big much-ballyhooed study that appeared to show organic produce was no more healthy than conventional produce. Many people with an axe to grind championed its findings, with some proclaiming the undeniable ringing of the final death knell of organic farming. Science Based Medicine wasted no time in weighing in on the current state of organic food, which they said “represents the triumph of marketing over scientific reality.” Strong words, words that seem to be – at first glance – supported by the study in question. But are they? Are you falling for marketing hype when you buy organic? Is it worth it?

To put this summary post and, more importantly, this 10-part series in perspective, let’s examine one of the most pervasive pieces of dietary advice given to people worldwide:
“Eating foods that contain any cholesterol above 0 mg is unhealthy.”

No summary of this length can begin to fully address a topic as comprehensive as cholesterol metabolism and the pathogenesis of atherosclerosis. In fact, those of us who challenge conventional wisdom often find ourselves needing to do exactly what Frederic Bastiat suggested:
A couple of weeks ago I wrote about slow living, the philosophy that encourages us to reclaim our time and consciously approach the way we live. Slow living isn’t as much about pace as it is depth of experience – absorbing the full dimension of each moment and relationship. In slow living and other conscious living philosophies, we’re called to re-sensitize ourselves to life. We notice more, feel more, and perhaps come to know ourselves more. We leave behind an existence led on autopilot. We let go of routinization that can reduce life to a manic drill. There’s another level to this picture, I think. Even in a peaceful, productive, and well-balanced life, we can find ourselves feeling restless. The comfortable plateau we’ve achieved – with all good intention – can seem less satisfying. Where did the peaks of life go? Do we make space for exuberance or adventure anymore? In seeking to live vitally, we inherently value more than the necessities of survival, more than the elements of comfort. It’s a mark of thriving, I think, to test the scale and dimension of existence – in whatever way fulfills us personally. We can choose to prioritize the role awe, adventure, and uncertainty in our lives. The fact is, the power of intermittent euphoria (IE) can fill a deep – and deeply human – well.
Anyone who’s been through a health store has heard about ions. If it’s not someone offering samples of ionized water, it’s someone selling ionized bracelets. It sounds wacky, woo-woo, crazy, and as if it belongs firmly in the same realm as crystals, magnet therapy, and cryptozoology (although the kid in me is still holding out hope that both Squatch and Nessie are found), but is there actual science behind this negative ion stuff, or are the people who buy into this stuff totally off their rockers? Today, we venture into what some might consider the realm of the non-scientific to discuss negative ionizers – both the natural kinds (like waterfalls) and the man-made variety (negative ion generators).
Let’s get to it:
