Ah, it’s good to be back with a regular old Dear Mark. Today we’re discussing the nutritional value of canned salmon, and whether the canning process negates some or much of the impressive nutrient profile of fresh salmon. After that, I discuss the dietary views of Ray Peat, an increasingly popular topic in the MDA forums and a seemingly wildly divergent way of eating. Is there any reconciliation to be made between Peat and Primal? I think so, actually. Finally, I explore why we might be inherently drawn to crispy, crunchy food despite the lack of potato chips, Fritos, and Pringles during the most formative years of our evolution.
Two weeks ago, I introduced you to five cosmetics ingredients you should avoid. These are chemicals you’ll often find in things like shampoos, conditioners, deodorants, sunblocks, and makeups – you know, the stuff you’re covering yourself in everyday. Cosmetics manufacturers use these ingredients to improve their product’s ability to clean, moisturize, beautify, or improve an odor, but they often do lots of other bad stuff in the process. So the question is, do these products need these chemicals to work like we want them to, or are there alternative products that manage to use more natural and/or less harmful ingredients while still getting the job done? Indeed, there are, and today I’m going to share my findings with you.
It’s Monday, which means it’s time for another edition of Dear Mark. This week, I’m covering four reader questions. First up is a really tricky one: ApoE4, the ancestral allele that’s classically associated with a host of maladies, like cardiovascular disease and Alzheimer’s. What’s the deal with it? We don’t have any concrete answers (yet), but I give my take on it. Next, I tell a reader who’s flying to Chile for vacation how I recover from travel-related sleep disturbances and realign my circadian rhythm. After that, I cover another paleo debunking that’s actually not much of a debunking, this time a TEDx video from Christina Warriner. And finally, I explore the eternal question of Halls cough drops, including whether or not any natural alternatives exist.
So this is my review of the new book Paleofantasy: What Evolution Really Tells Us About Sex, Diet, and How We Live. It’s been making the rounds for a few weeks now, and although some other people have already weighed in, I’ll add my two cents. At the outset, I’d like to make very clear that I actually agree with a decent portion of Marlene Zuk’s individual arguments. Though it may surprise you to know that Mark Sisson agrees with the most prominent paleo debunker du jour on several topics, I’m not saying I support the overall product or her final conclusions. In fact, Paleofantasy is an odd, meandering book whose ultimate purpose I’m not really sure I truly understand.
There are two main problems with the book, as I see it. First, she’s working against a straw man. Many of the arguments she debunks, like “eyeglasses aren’t paleo” or “the paleo diet was carnivorous,” seems to have been dug up from some random Internet commenter or drawn from fringe camps. In other words, they aren’t arguments people like Robb Wolf, Chris Kresser, Paul Jaminet, or me (or our readers) are making. Second, many of her counterarguments or “nuanced approaches” are the very same ones we’ve been exploring at length for years! After reading the book, John Durant tweeted “Paleofantasy shouldn’t have been a book in 2013, it should have been a blog post in 2010,” and that’s as good a description as I can think of.
I regularly get emails asking what’s on my bookshelf (or RSS feed). Now and then I like to answer those questions and share a bit of what I’ve been up to. Truth be told, my reading of late has revolved around themes I’m covering in my upcoming book, The Primal Connection. Think along the lines of play, creativity, ancient wisdom, sensory experience, social bonds, hunter-gatherer history, and an inner wild (to name just a few). In other words, it covers the many lifestyle elements that can further connect us with our inherent blueprints – beyond the basics of diet and fitness. The method (as always) examines the incongruence between how we evolved and how we live today. The purpose, of course, is informed choice to help us create healthier, more content, and fulfilled lives in the modern age. I’ll make an official, more detailed announcement in the coming weeks, but I can happily divulge this much today: it will be hitting the shelves September 17th.
Now for a look at some of the books I’ve been reading…
