Last week’s whey protein post generated a ton of great questions. I’m going to try to get to as many as I can today, and I’ll include information on alternative protein powders at the end. As always, let me know if I miss anything and I’ll try to rectify that in the future.
What about oxidized cholesterol? Aren’t most whey protein concentrates exposed to significant amounts of heating that oxidizes the cholesterol?
Oxidized cholesterol is potentially dangerous. In fact, along with Ancel Keys’ fudging of the saturated fat intake data, it was the oxidized cholesterol-fed rabbit model that jumpstarted the crusade against fat and cholesterol. Undamaged dietary cholesterol wasn’t atherosclerotic; oxidized dietary cholesterol was the stuff that contributed to arterial plaque (feeding pure cholesterol to an obligate herbivore played a part, too) in the rabbit.
We’re long overdue for a good, solid post on whey protein. I include it in my Primal Fuel shake mix, a number of readers asked about it after last week’s dairy post, and it’s one of the more commonly used nutritional supplements around, so it’s a no-brainer of a post.
Whey is a byproduct of cheese production. It’s that pseudo-clear liquid remaining after milk has been curdled and strained that used to be tossed aside as waste material. Today, we know that it houses an impressive array of proteins: beta-lactoglobulin, alpha-lactalbumin, and serum albumin. These are complete proteins, comprised of the essential amino acids central to protein synthesis and increased muscular hypertrophy. Our bodies can produce non-essential amino acids from lesser amino acids, but we cannot produce the essentials ourselves; we must eat quality protein sources. Whey is a naturally occurring, essential protein that satisfies the body’s protein requirements – hence its popularity.
I was going back over the MDA archives this week, thinking about what went right and what went wrong with past posts. There are always going to be regrets when looking at past work, whatever its nature. That’s just how these things work.
But this is the internets, not print, and I can quickly hop in and make changes to the past with just a few keystrokes. Or, I can write an honest appraisal of my previous transgressions and come up with a post of restitution. This is that post of restitution. Today, I’m admitting that my last post on cowpooling was a bit lean. It’s not that I trimmed the fat; it’s that the fat was never even there in the first place (hmm, old Cordain might agree). Consider this post a dollop of grass fed butter in the pan that is MDA’s cowpooling content, perhaps even after deglazing all the tasty bits with a hearty Zinfandel. Today, I’m going to tell you how to find a cowpooling source so you can buy grass fed beef in bulk directly from the supplier.
Yesterday, I debunked a few of the common, “evolution-based” arguments leveled against meat-eaters that might have the potential to stump anyone with only cursory knowledge of evolutionary science. By and large, these are arguments that appeal to our emotions. They invoke a peaceful, gentle pre-history of slender, humane early humans co-existing in perfect meatless harmony with the animal kingdom, an image that sounds great and makes us feel all warm and fuzzy inside. Those sharp spears found at various dig sites, you ask? Why, those were just used to skewer hard-to-reach apples, or perhaps to gently separate two squirrels battling over an acorn. But the fossil record shows distinct markings on large ruminant bones that seem to indicate cuts, tools, and butchering – how do you explain those? Oh, those? See, early humans were so grossed out by animal carcasses that they couldn’t bear to actually touch them with bare hands. They developed tools so that they could move the offending meat out of their line of sight without actually putting hands to flesh. Pretty ingenious!
Meat is murder.
Meat will clog your arteries.
Meat is an unnatural food.
Man is really an herbivore.
Meat will give you cancer.
Meat is bad for the environment.
It’s easy to forget that these are the common arguments leveled against meat-eaters. It’s easy to forget that most of the developed world assumes meat is inherently unhealthy – for our health, for the environment, and for animals. It’s easy to forget these things because, as Primal Blueprinters, we’re immersed in the literature and are actively involved in what we eat. To that end we understand that man evolved eating meat, that meat is an important part of a healthy human diet, and that meat production doesn’t have to be the unsustainable, industrialized monster it’s mostly become (and which rightly garners the most negative press). Still, what is the average meat eater to say in opposition to these charges?
