This is a special guest post from expert study-dismantler Denise Minger. (Read Denise’s previous guest posts – Will Eating Whole Grains Help You Live Longer? and High Fat Diet Linked to Breast Cancer? – and her blog at Raw Food SOS.) Enter Denise…
Like salmon? Pop fish oil? Got a prostate? Then listen up. A new cancer study rolled in this week, and at first glance, it looks like bad news for any fish-loving men out there. A team of researchers at the Fred Hutchinson Cancer Research Center found a disturbing link between blood levels of DHA – that darling omega-3 fat abundant in seafood – and the risk of developing aggressive, “high-grade” prostate tumors.
Unless the afterlife has wifi, I can presume that you’re alive and reasonably well if you’re reading this post, so I’m going to assume you’ve been successfully breathing for some time. You get enough oxygen into your blood to support your physiological requirements and power your limbs, organs, and muscles. You know how to inhale, and exhaling is a breeze. You even know how to breathe through your nostrils like a champ. In other words, you can breathe well enough to live. What could you possibly be missing?
There’s a pretty good chance you aren’t breathing correctly. At rest, when sleeping, while running – you can probably breathe different and breathe better. Okay, you’re willing to accept that, as a whole, we’ve missed the mark on a host of supposedly mundane activities – eating, exercising, sitting, sleeping, standing, washing, heck, even pooping – but breathing? You’ve gone too far this time, Sisson. You’re firmly in the deep end. I breathe just fine.
Even if your workdays consist of alternating between hunkering down over the laptop in a full Grok squat with perfectly neutral lumbar spine and standing up at a standing workstation for the entire work day you’re likely still engaging in some anatomically novel and potentially problematic habits. The bulk of you folks might get away with wearing minimalist shoes to work or maybe padding around the office in socks, but I imagine most people are sitting down, staring at a screen, and making strange tapping motions with their fingers splayed out in front of them for seven to eight hours a day. If this sounds a little too familiar you could probably use some help. I know I could.
As promised in last week’s Hunter-Gatherer Fitness post, I’m stirring up the (apparently much awaited) subject of sex – specifically the benefits for physical and mental well-being. Uh, you mean coitus? Yup. Thanks to everyone who responded to the announcement with rousing enthusiasm as well as comments and questions.
What could be more Primal than sex, many of you have suggested. Absolutely right. It was probably one of Grok’s most valued pleasures. (Are people today much different?) For our part, however, we have new freedoms in a manner of speaking. Although we might honor the evolutionary imperative behind our primal appetites with eventual procreation, we’re not beholden to the natural odds with every tryst. As I’ve said many a time, I love studying and learning from the example of Grok and his kin. Nonetheless, I’m a happily modern man in this instance as much as any.
Calorie restriction is all the rage in anti-aging circles. A few mice and worm studies seem to show that drastic reductions in food intake over a long period of time have the effect of prolonging life – although I’m not sure I’d call it living. For one, these animals are actually restricted. There’s no ad libitum access to food. They’d prefer to eat more, but are prevented from doing so. I guarantee you they’re unhappy and, if they could put (cartoonish high-pitched) voice to physiological state, would say they’re starving.
