New genetic research shows that the ability to digest starch helped mark, in part, the passage from wolves to dogs. This implies nothing about thriving, however, as anyone who’s put their pooch on a grain-free, animal-based diet can attest.

Marion Nestle discusses the study that recently revealed ties between Big Food and Registered Dietitians. I’m disappointed, but certainly not surprised.

Comment of the Week

The next post on co-sleeping should be about cats and dogs. I find it incredibly comforting to sleep with our cat right up to when he is co-sleeping on my head while chewing on my hair or licking my eye.

– Maybe, Juli. I’ll look into it. I certainly do love the feel of a sandpaper cat tongue against my cornea.

You want comments? We got comments:

Imagine you’re George Clooney. Take a moment to admire your grooming and wit. Okay, now imagine someone walks up to you and asks, “What’s your name?” You say, “I’m George Clooney.” Or maybe you say, “I’m the Clooninator!” You don’t say “I’m George of George Clooney Sells Movies Blog” and you certainly don’t say, “I’m Clooney Weight Loss Plan”. So while spam is technically meat, it ain’t anywhere near Primal. Please nickname yourself something your friends would call you.

  1. Yikes. That article about RDs is frightening. The thing is, as far as having credibility and being allowed to practice nutrition, an RD is the gold standard (at least in NC). Because of that, I’ll probably end up getting my RD, and if nothing else it will be an eye-opening experience to see what they teach these aspiring nutritionists! But the whole nutrition education system is just messed up.

    • Unfortunately, it is. My Aunt is a Registered Diet Technician (just below RD) and I can say she’s not meaningfully in the pocket of Big Food. However, she’s struggled with obesity all her life and just recently got gastric by-pass surgery. Went I went low-carb, she “causally” asked me how I was going to get the B vitamins. I said “meat”. (Uh, she’s the dietician?)

      Quite often the problem is, not unlike with therapists, that those who are attracted to the profession and credentials are looking for answers for themselves. My Aunt has a problematic relationship with food to say the least.

      Anyway, good luck. The best way to change a profession is from the inside. Get the credential and then do what you can to improve the situation.

  2. You can tell Marion Nestle is onto the truth. Judging by all the RD negative comments posted she hit quite a nerve. Apparently the truth does not act as novacaine.

  4. I’m in my internship now & 5 months away from being an RD, and I loved reading her article! There was a ton of great responses from other RDs that got a conversation going about the sponsorship. It’s good to see there’s plenty of RDs out there that do not agree with it – many who probably will not be renewing their membership with AND (I won’t be). I never look at AND’s “evidence analysis library” because I’d rather find other non-biased research out there.

    • Oh Lauren do you have any advice? I graduate with my Bachelor’s in Nutrition/Dietetics in May and I am currently going through the DICAS/D&D process. I’m trying desperately for Bastyr University (holistic nutrition). Congrats on getting your internship and good luck on the RD exam!

      Emily Mekeel wrote on January 27th, 2013
      • Good luck! I’ve heard good things about that program, and I’m sure it’s better because it is holistic nutrition based. My advice for applications is make your goals clear and explain how that program can help you reach them. Other than that – during the internship, I’ve found that I can promote different topics like animal protein as high quality protein and whole food (vs processed) as much as possible without saying “paleo or primal.” Other times like in clinical – you just gotta push through without getting too angry – like when the other RDs are sending up Ensure or milkshakes to get patients to eat (or when patients are stuck ordering low cholesterol eggs because they’re on a cardiac diet!).

  5. Loved the art of manliness article. After thinking about your answer to how to get rid of gynoid fat by increasing testosterone, I’ve been trying to learn more about testosterone, and this article did the trick!!

    Now I’m curious to the effect of bjj on testosterone. It involves whole body movements against resistance (your opponent), so while it involves all the big muscle groups… I’m not sure it counts as lifting heavy things.

    Also the competitiveness I feel when sparring feels pretty primal and testosterone laden… But that may simply be from all the adrenaline… Released because in bjj there is a lot of fight and flight!

    Also surprised to read his link showing that eating low carb can be detrimental to testosterone production. Not sure i quite buy that.

    • The only thing I never enjoyed about those articles on increasing testosterone was that Brett McKay recommended that you shouldn’t be on a “Caveman” diet and gave a piece of research why.

  6. The Art of Manliness article links to MDA cholesterol articles, but goes on to cite a study which says eating paleo/carb lowers testosterone.

  7. I have no particular interest in maxing out my testosterone but I am convinced that following Primal has significantly boosted mine. I don’t have any tests to prove it but lots of changes lead me to believe it is true, e.g. the “meter” that men have when they wake up in the morning. I have a good meter reading, especially considering that I’ll be 70 in two weeks.

  8. I would caution agains vacuum sealing storage bags like zip locks for heating food. Volatile compounds in the plastic may leach into foods and mimic estrogens. Perhaps this technique would be OK for freezer storage.

    Food Saver bags typically used in sous vides cooking are supposedly safer.

    Great tip for when you’re using zippered freezer bags as demonstrated, but erm, fat-free mac and cheese?! If I’m gonna eat that crap, you’d better believe it’ll be made with a super-creamy cheese sauce!! Wow.

  10. re: vacuum sealing food

    I usually “vacuum seal” half avocados and stuff by sealing the bag almost all the way, then sucking the last of the air out myself. It works pretty well, especially since the said avocado usually gets consumed within 4-24 hours!

  11. Arggh! That article by Marion Nestle highlights the issue I have as I pursue a career in nutrition counseling. I feel that I need to have the RD status but it makes me feel like a complete hypocrite because I am against everything they stand for. It’s so difficult to decide an education path that will get me where I want to be in my career without sacrificing my beliefs. Such a shame that the two have to be at odds.

  12. One of my friends pointed to the wolf->dog story as an example of why stuff like Paleo is dumb because “we’re evolving all the time, people!”

    DarcieG wrote on January 27th, 2013
    • Humans haven’t exactly “evolved” in a very long time, maybe mentally but physically never. Our guts have been about the same length since our transition to an omnivorous diet. People of this community tend to agree that the Paleolithic diet is fixed because you need to eat what you were meant to eat… unless your species decided to take a spin in the other direction and make tools and fire. Our species may be lucky.

      Peacemaker wrote on January 27th, 2013
      • Mmm, that’s not scientifically accurate. There is change in the distribution of alleles in human populations currently occurring, e.g. evolution.

        As far as new mutations occurring and being selected for, there are cases of human evolution occurring since the Paleolithic Era, which ended 10k years ago (ex. http://www.nytimes.com/2010/07/02/science/02tibet.html?_r=0). Lactose persistence is one such “recently” evolved trait.

        Like you, I enjoy reading this blog and in general consider Paleo foods enjoyable and healthy…but let’s be careful not perpetuate inaccuracies and misconceptions about evolution while we do so.

        Scientista wrote on January 31st, 2013
    • the article is misguided. dogs did not really involve to eat grains anymore than humans.

      dogs evolved overtime to become more domesticated. If you read “the Greatest show on earth” by Dawkins you would read how scientists attest to the theory that wolves who evolved a to have a less timid/aggressive flight/fight neurology became the dogs we see today because they were able to live close to ancient human camps as opposed to other wolves and species were weary of cohabiting with humans. remember the assumption that living with humans and cohabiting with them is not unusual if you take out the perspective that humans are separate from nature. in the animal kingdom it is likely that hominoids and canines bonded for survival and evolved to be cooperative species instead of aggressive fighters

      it suggests that domestication took off when agriculture did but i beg to differ and question his science. i do not believe that canine to dog domestication happened that recently. if you look at nomadic tribes that use dogs you would see that they are foragers, hunters and pastoralists. nothing about agriculture.

      also remember the assumption that the agricultural revolution occurred globally at one point is false since many different societies even today practice various forms of subsistence. but the fact hat even the not agricultural humans have had dogs would say that we did not domesticate dogs through the means of introducing them to starch.

      i would also think that many dogs would have been fed meat considering that they were initially used for hunting and therefore they held on to the instinctive thirst for flesh .

      now have canines developed abilty to digest grains? i doubt it . many good vets would tell you to not buy the dog foo that is filled with these starches. I buy my dog Primal Pet Foods for that very reason. and it shows that these foods are healthier diet

  18. My friend has free roaming chickens and I get my eggs from her. I love those eggs! When I’ve run out and haven’t given her a box for a refill, I buy free range eggs from the supermarket. I can tell immediately the difference in quality. Her chicken’s eggshells are hard and don’t break the yolk when I crack them, whereas the supermarket’s free range eggs have brittle shells. I asked her what she feeds her chickens and she said everything. Since I know she eats a ton of meat I asked her if she feeds them meat scraps too and she said that her chickens eat the scraps of meat, the bones, fat, veggies, fruit, bread, cereals, even left over chickens and omelettes! Well there you have it. I reckon her chooks are by far the healthiest.

  19. I’m an RD in Canada, so part of a different professional organization, but I get mailings from Pepsico, The Sugar marketing people, lots of undesirable “low fat”, functional food type stuff. It all goes straight into the recycling bin. I agree with Marion Nestle that it’s inappropriate and embarrassing to have those sponserships for an organization that promotes good nutrition. Even CW “good nutrition” doesn’t promote soft drinks and candy…

  26. Hi Mark! I am enrolled in “Basic Human Nutrition” this semester at our community college. Just last week I had an issue with my instructor regarding the use of canola oil (which I do not use). I have been following the Paleo/Primal for about year now. She also extols loudly on the necessity to have grain in our diets. Amazing how many students here graduate with an Associates degree in Dietetics and they weigh more than 300 pounds and can’t walk due to inflammation!! Lovely to see this post on RD’s, believe me!
