GMOs: Safe for Consumption?

GMOCornWe’ve examined the arguments for and against GMOs in the past. Indeed, there are reasonable and valid points to be made on both sides of the issue. Nonetheless, we concluded that there are just too many red flags to support the industry’s direction in GM technology. Not only do GMOs drive the use of naturally occurring and regionally suited seed varieties into the ground, they lock farmers (including those in developing countries) into a legal deal with the devil – one that often comes back to haunt them. Their rampant subsidization further encourages farmers to raise the same garbage grains and other “staple” crops that undermine our public health. And then there are the nagging, unsettling questions about our physiological response to these organisms. What happens exactly when you eat plants grown from seeds that are synthesized with everything from bacteria to fish to herbicides? What happens when you eat the animals that ate these crops? How much do we really know about these GM crops? With that in mind, a good reader sent this recently published study my way. See what you think.

The Definitive Guide to Oils

healthyoilsBefore you can hope to make it as a speculator and start slingin’ barrels for big money, you’ve got to understand exactly what’s gushing forth from the earth’s crust. Yes, that’s right – it doesn’t start and stop just with crude, and there’s far more to oil than dinosaur bones. In fact, most experts agree that the bulk of crude oil is derived from prehistoric single-celled plankton remains. Then you’ve got the abiogenic theory, which posits that…

Er, wrong oils. Sorry.

Today’s post is actually about edible oils. Well, they’re all technically edible – they can all be swallowed and digested – but as for being palatable, let alone healthful? That remains to be seen. Not all oils are created equal, especially given the fact that most of the ones people use nowadays are actually created in an industrial laboratory. No oil “exists naturally,” mind you. Olive oil isn’t harvested by leaving open containers under leaking, dripping olives on the branch, nor is that liquid sloshing around inside a coconut pure oil. I’m not trying to disparage processing in and of itself. It takes a certain amount of processing to get any sort of oil, but a good general rule is to avoid consuming the oils that require processing on a large scale. If it involves an industrial plant, multiple stainless steel vats, a deodorizer, a de-gummer, and the harsh petroleum-derived solvent known as hexane, I wouldn’t eat it. But that’s just me (and Grok, who probably wasn’t processing wild rapeseed to get the precious canola oil).

But this is the Definitive Guide to Oils. Everything goes. No stone left unturned. No oil left un-tasted and bereft of analysis for fatty acid profile, oxidative potential, and rancidity proclivity.

The Wonderful World of Coconut Products

coconutCoconut seems to have a special place in Primal hearts. Judging from the forums, people are pretty taken with the fatty pseudo-nut and they’re always interested in new ways to consume the stuff. For some who abstain from dairy completely, coconut products make a great replacement for creams and butters. Others see the evidence from South Pacific traditional groups who thrived on a diet of coconut and fish, and want a bit of that in their lives. The milk makes a great base for smoothies, soups, and curries; the oil is a great source of saturated fat that stands up well to heat; the water beats commercial sports drinks with its impressive electrolyte content; the nut itself can be used as a projectile weapon. It’s just a well-rounded, versatile food with some interesting characteristics and a ton of offshoot products. Unlike most food “products,” however, coconut products are legit. They’re real food, and they’re real good. To help you guys wade through the often-confusing world of coconut products, I’ve put together a little guide to them all. Of course, I’ve probably missed a few things, so share your thoughts with me in the comments section.

Dear Mark: Trans Fat

transfatThe message has been circulating for a few years now: trans fats = bad. It’s one of the rare times I find myself in alignment with conventional nutritional guidelines. (Of course, it’s not so simple, but I’ll unpack that one in a moment.) The fact is, manufacturers have done a better job sending the anti-trans fat message than public health agencies. Everywhere you turn in the grocery store the “No Trans Fat!” tag leaps out at you, complete with manic font and exclamation point, from hundreds of boxes, bags, and packages. (“Well, it must be healthy then!”) Unfortunately, the marketing push has crowded out the real science when it comes to the public’s engagement with the real issue. As you can guess, there’s more to the trans fat picture than the self-congratulatory manufacturer claims.

Dear Mark,

I know trans fats are unhealthy and I avoid them like the plague. But like so many things sometimes I need a little reminder why. (I regularly brush up my knowledge by visiting your site so that when a friend asks why I avoid grains I don’t say something like “Grains are bad because… something about lectins and phytates – can’t remember why… but they’re bad.”) Could you write up an easy to remember primer on what trans fats are and why are they unhealthy?

Weekend Link Love

weekend link lovePrimal is spreading. If you haven’t already seen it, the New York Times ran a piece on modern cavemen in the big city. You’ll probably recognize a few of the people they interviewed.

Zen Habits included me in his recent post about health bloggers’ favorite blogs. Even for the hardcore Primal fans, there may be a few blogs you haven’t heard of.

If you haven’t read Good Calories Bad Calories yet, I’d suggest heading over to Higher Thoughts where you can read extensive notes on the entire book.

Barefooters gain the upper foot after more research comes out on the ineffectiveness of high tech running shoes.
