I get a lot of emails on a lot of subjects. “Mark, is toothpaste Primal?” “How many micrograms of wheat germ agglutinin can I safely consume each day?” “Did Grok even lift?” Usually, I manage to address them in the Monday Dear Mark posts, but sometimes a question deserves its own dedicated midweek post. Today’s question, or rather pair of questions, definitely qualifies. First is the titular question, “How much protein should I eat?” I get that one a lot, even though I’ve covered this in my books and in various blog posts. The second question is “How much protein do you eat, Mark?” Before we get to my protein intake (which has changed in recent years) let’s explore how much protein you should be eating. The answer – wait for it – depends on who (and what) you are. Your goals, your age, your activity levels, your size, and your health status all impact how much protein you need. And although individual protein requirements ultimately depend on dozens of variables that we can’t really know, there are some baseline intakes that can serve as a foundation for different groups. Let’s take a look.
There’s another “meat is bad” study making the rounds, featuring such stellar prose as:
“Although causality cannot be established…”
“…further research is recommended.”
“…should still strive to reduce intake of red and processed meat, which tend to contain high amounts of saturated fat and sodium.”
And so on.
By now, we see these lines, roll our eyes, and keep on moving down the path that seems to be helping us. But that’s us, people who pay attention to nutrition news and stay abreast of the literature. We may be able to write off these breathless articles without thinking we’re going to die because we ate that bunless burger the other day, but our parents, our friends, our colleagues may not be so well-equipped. They’re worried about our health, and who can blame them? If you take mainstream health articles at face value, articles which confirm what your doctor is probably telling you, you would do the same.
We now know that the oft-repeated “your brain only runs on glucose!” is wrong. I’ve mentioned it before, and anyone who’s taken the time to get fat-adapted on a low-carb Primal eating plan intuitively knows that your brain doesn’t need piles of glucose to work, because, well, they’re using their brain to read this sentence. Obviously, you eventually adapt and find you have sufficient (if not much improved) cognition without all those carbs. That said, some glucose is required, and that’s where people get tripped up. ”Glucose is required” sounds an awful lot like “your brain only uses glucose” which usually leads to “you need lots of carbs to provide that glucose.” And that’s the question today’s edition of “Dear Mark” finds itself attempting to answer: how much glucose is required?
Let’s get to it.
This is another special guest post from our favorite study-dismantler, Denise Minger. Read all of her previous Mark’s Daily Apple articles here, here, here and here, pay her website a visit, and stay tuned for her upcoming book “Death by Food Pyramid” due out later this year.
We’re already 74 days into the new year, which can only mean one thing: it’s high time for our latest episode of Science Says Meat Will Kill You, complete with a brand new study and commercial-free viral media coverage! Have a seat and tune in (or at least set your DVR for later viewing).
If you haven’t had at least one family member, coworker, or soon-to-be-unfriended Facebook acquaintance send you this study as a reminder that you’re killing yourself, you’re either really lucky or your inbox is broken. Thanks to an observational study called Red Meat Consumption and Mortality freshly pressed in the Archives of Internal Medicine, a slew of bold headlines exploded across every conceivable media outlet this week:
If 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.
