This may seem like a redundant topic, since most of you following a Primal eating plan are already avoiding wheat. The occasional dabbing of soy sauce, maybe a bit of crusty bread at a restaurant, sure, but for the most part, you’re not munching on baguettes in parks on sunny days, wolfing down huge sandwiches, and eating pasta. Wheat avoidance tends to be the rule in our circle. Still, though, haven’t you had that moment where someone asks “What’s wrong with wheat?” and you mutter something about gluten and the advent of agriculture that doesn’t really sound convincing, even to you? Consider today’s post a crash course in exactly why modern wheat in particular is a problem. To borrow a horrible concept that has helped politicians and their cronies obfuscate the truth for decades, these are “talking points” to which you can always refer when asked. The only difference is that these talking points are based on actual research.
A new study came out last month out of France. In it, researchers found that rats on diets consisting of 11%, 22%, and 33% Roundup-resistant genetically modified corn developed far more mammary tumors than control rats on non-GMO corn diets. GMO diet rats died earlier and in greater numbers. Why is this study notable amidst all the other studies that seem to show the safety of GMOs? Well, it’s one of the few long term GMO feeding studies, lasting a full two years, which, to a rat, is the equivalent of 60 of our human years. The other safety studies which found no evidence of toxicity in GM foods tend to last just 90 days, or 15 rat years. In other words, the French study studied rats over the course of an entire lifespan, whereas other studies have looked at rats for a relatively brief snippet of their lives. Cancer generally develops over a lifetime, as you probably know, so this would appear to be more relevant to human health than the shorter trials.
This is a guest post from Mira and Jayson Calton of Calton Nutrition. As many of you know, I’ve written extensively on the seasonality of eating, and the fractal nature of early human existence. In this guest post, the Caltons share a few of their own insights and discoveries on seasonal eating patterns, and provide a new perspective on weight loss plateaus. Enter the Caltons…
“Whoever wishes to investigate medicine properly should proceed thus: in the first place to consider the seasons of the year.”

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?
