From the presence of vitamin D receptors in our cells and vitamin D factories in our epidermis, along with the central role vitamin D plays in calcium metabolism, immunity, and gene expression, it’s pretty clear that having adequate vitamin D is an essential component of being a healthy, successful homo sapien. And yet, many health practitioners suggest that vitamin D deficiency is one of the biggest nutrient deficiencies in modern society. The question, then, arises: What’s the best way to get enough vitamin D – via oral supplementation or sunlight?
To determine that, let’s examine a few common questions surrounding the various modes of intake.
Before phototropic plants began bending toward sunlight, before jellyfish developed ocelli, the light-sensing organs that allow them to distinguish between up (sunlight) and down, before the bikini-clad beach denizens began tanning en masse, and before the first house cat followed the sliver of sunlight around the room all afternoon, our primitive, microscopic marine forebears were flourishing by converting the sun’s energy into chemical energy usable by biological life. You’re probably aware of photosynthesis, the process by which plants, algae, and other organisms do it and produce byproducts like oxygen, but even the unicellular archaea that do not produce oxygen utilize sunlight for energy. And if you aren’t obtaining energy directly from the sun, you’re probably eating the organisms that do. Either way, sunlight directly or indirectly supports all life (well, except for the chemoautotrophs living in deep sea hydrothermal vents feeding off of inorganic energy sources like iron, ammonia, or sulfur).

Do you have what it takes to unleash your inner Grok?
Everyone does. It’s inherent in our biology. And yet many don’t, not because of physical obstacles but mental ones. Such barriers manifest as false and misguided perceptions of Primal living’s complexity, difficulty, and restriction. Alas, these devilish traps inhibit many would-be Groks from realizing their full potential.
So, how do you evade these ensnarements and unleash your inner Grok?
You stop worrying about “how” you’ll live Primal and start thinking about “why” you should.
The “why” is essential. If you don’t know why you should adopt Primal living then you never will. How come? Because the “why” gives meaning to what you do. And when you have meaning you have the strength and resolve to succeed.
This simple 1-2-3-4 forumula will guide you to “why” Primal living is right for you. Have fun with it and get ready to unleash your inner Grok!
Ever watch dogs at play, carefree? Next time you go on an off-leash hike with a canine, or even just a walk around the neighborhood, watch how they just jog along. Assuming they aren’t in pursuit of cat, squirrel, or pedestrian, it’s an easy trot, an effortless series of flicks of the ankle joints. It’s smooth, and their heads and shoulders stay mostly level with the ground. No off balanced dipping or stumbling. Oh, sure, the composure goes out the window when a frisbee’s let fly and they tear off after it, tongue flapping and fur rustling and muscles pumping, but to watch a calm, curious off-leash dog trot around, checking out the surroundings, sniffing, and just taking it all in is to watch an animal at total, complete ease in his own (furry) skin. We can learn a lot from watching dogs, as I have from my own Yellow Lab, Buddha.
Probiotics get a ton of positive press from a multitude of sources (including here). It’s one of those areas of nutrition that receives approval from pretty much every camp out there, like fish oil. (Even Dean Ornish supports the usage of fish oil; just about the only type of fat he seems to approve of.) I’m firmly in the “For” column as well if you haven’t already guessed. I feel so strongly about probiotics and their integral role in gut and overall health that, as you may know, I’m coming out with a probiotic supplement in a few weeks. But there’s another aspect to the manipulation of beneficial gut flora. I briefly mentioned them last time, and today I’m going to really gut the whole beast, so to speak.
