Bone Marrow: Delicious, Nutritious and Underappreciated

boneMarrowIf you’re truly interested in consuming the original Primal brain food, look no further than bone marrow: perhaps the first reliable source of large, fatty animal products our scrappy ancestors were able to procure. Yes, before we became spear-using cunning tacticians surrounding, stalking, and out-maneuvering large prehistoric ungulates, we feasted on the bones of fallen prey. Or, more accurately, we feasted on what lurked inside the bones (and the skulls, for that matter). Animal fat and protein improved the quality of our diet by making digestion less energy intensive. Bone marrow, especially, was highly caloric and nutrient dense, allowing early human ancestors to divert metabolic resources away from the costly digestion of roughage and toward bigger, costlier brains. This spurred the increase in hominid brain size that we still enjoy today.

How Much Is Too Much?

Stop 1Although the Primal Blueprint leaves ample room for individual determination, I do try to offer folks a clear picture of the impact different dietary and lifestyle choices have on their overall health picture. At times I even offer specific recommendations or ranges that readers can tailor to their particular needs and situations. I’m often asked, however, about the upper ceilings I would set for various elements of the PB (fat, fish oil, etc.) I thought I’d take on those questions today and cover good ground by applying a rapid fire approach for several of the most common “excess” inquiries. Enjoy, and be sure to share your thoughts!

Dear Mark: Nuts and Omega-6s

mixednutsNuts have gotten a surprising amount of flack as of late. Many nuts have a fairly high PUFA content, and most of that PUFA is Omega-6, which is the bad one. It’s easily oxidized, highly unstable for cooking, usually rancid on the shelf, and, thanks to government farm subsidies and public hysteria over animal fat, it’s in absolutely everything nowadays. We Primal types generally avoid it for good reason, and that tends to influence how we react to the O6 content of nuts. Last week I received this email from a reader:

Dear Mark,

I’m a little confused. I get the animal fat, the meat, the veggies, and the lowish sugar fruit recommendations, but what about nuts? I love nuts, don’t get me wrong… I’m just a bit paranoid about the Omega 6 content. You recommend nuts in the book. If you (and pretty much all other Primal bloggers) tell us to avoid Omega 6 fats, should we still be eating them?  I’m having trouble reconciling the two bits of advice and there seem to be mixed messages out there. Thanks.

Is there a place for nuts in the Primal Blueprint diet? Let’s take a closer look.

Dear Mark: Omega-3s and Fish Allergies

fishoilBy now we all know the benefits of fish oil and its omega-3s: lower risk of heart disease, stroke and cancer, less systemic inflammation, lower risk for depression, better skin, and so on. Although fish and fish oil supplements are the best sources for these omega-3 benefits, there are nonetheless scenarios that rule out these sources.

Dear Mark:

I’m sold on the benefits of a Fish Oil Supplement and I’m interested to start taking one. However, I have had serious allergic reactions to Shell Fish in the past, and an allergist has shown me to be reactive to most fish in general. As such I have avoided anything and everything that swims for a very long time. Maybe it’s possible my allergies were due to inflammation caused by my CW diet, but I’m still wary to test my theory now that I’m eating Primal. I feel like I’m missing out on a huge variety of food and supplement options. Question: I know anything can cause an allergic reaction, but is there any scientific basis for Fish Oil Supplements causing allergic reactions in people who have demonstrated allergies to fish/shellfish? And if so, what are my options for proper Omega-3 supplementation?

Can Fried Food Be Healthy?

FriedTurkeyFried food is regularly pummeled in the village square by CW because of the fat content. We Primal types know better of course. Although we eschew the carb-based foods (potatoes, donuts, corn chips, battered/breaded everything) that disgrace fry pans and deep fryers everywhere, we get along fine with the fat itself. I get a lot of questions from readers about frying foods – whether frying is a truly Primal practice and how frying can be done properly to avoid oxidation and retain nutrients. I know there are a lot of fried fans at MDA, and I hope they’ll share their tips as well.
