The Modern Assault on Eyesight

eyeWe 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?

Are Oats Healthy?

groatsYou know how we say that grains exist on a spectrum of suitability, from “really bad” wheat to “not so terrible” rice? Well, what about the rest of ‘em? They may be the most commonly consumed (and thus encountered) grains, but wheat and rice aren’t the only grains on the spectrum. Since I get a lot of email about oats, I figured they were a good choice for this post. Besides – though I was (and still mostly am) content to toss the lot of them on the “do not eat” pile, I think we’re better served by more nuanced positions regarding grains. Hence, my rice post. Hence, my post on traditionally prepared grains. And hence, today’s post on oats. Not everyone can avoid all grains at all times, and not everyone wants to avoid all grains at all times. For those situations, it makes sense to have a game plan, a way to “rank” foods.

Today, we’ll go over the various incarnations of the oat, along with any potential nutritional upsides or downsides. But first, what is an oat?

Does Eating Red Meat Increase Type 2 Diabetes Risk?

hotdogsIf you already eat Primal, your email inboxes are most likely filling up with links to the story. Concerned mothers clutching the local paper’s “Health” section are calling (or, if they’re hip, texting). Smug vegetarian Facebook friends are posting the story on your wall, sans commentary. Yes, it’s about that time again. It’s another week, it’s another observational study by data-mining researchers hoping to establish a solid link between red meat and some chronic, horrific illness. So, what’s killing us this time? Well, considering that they’ve already done studies linking red meat to colorectal cancer, heart disease, and outright death, type 2 diabetes is next.

Dear Mark: Hempseed, Too Much Omega-3, and Vitamin D’s Halflife

hempseedsIt’s a lovely summer morning here in Malibu. The cool sea breeze keeps the coming warmth at bay, for now, and makes me glad for the hot mug of coffee I’m clutching. I’ve still got a couple hours before heading into the office, so I’m hoping that I can get this post wrapped up and edited in time to hit the water for a bit of paddle boarding. We’ll see. I’ll try not to rush things too much. Today we’ve got a quick round of questions on a diverse set of topics: the suitability of hempseed in the Primal way of eating, whether you can get too much omega-3, and how long vitamin D lingers in the body before you need to replenish your stocks. As always, feel free to keep the questions coming and I’ll do my best to get to them!
