Dear Mark: Fat Triggers Marijuana-Like Chemicals, Another Anti-Meat Report, and Teff

By Mark Sisson
63 Comments

How was the weekend for you? Mine was kinda tough. Great weather beckoned all weekend, and my paddleboard and I shared mournful glances full of longing, but I was stuck inside working on my talk for the upcoming Ancestral Health Symposium at UCLA. I think it’s going to be a good one, though, so hopefully the work pays off. Okay, enough complaining. It’s Monday, which means another round of questions and answers. This week, we’ve got a pair of scary studies that seem to condemn fat and red meat as the nutritional factors ultimately responsible for all that ails us as a society (what else is new?). I also field a question on teff, a grain used in traditional Ethiopian cooking, from a reader who plans on moving there.

Dear Mark,

Could you comment on this study? Family members have been smugly forwarding articles about it, and I can’t take it anymore.

Body’s Own Marijuana Chemicals Trigger Love of Fat

Thanks,

Sandy

Sure. It’s a pretty interesting one. Rats were “sham fed,” which means they were fitted with a tube that kept swallowed food out of the gut. Since the rats could swallow and taste food normally, this allowed the researchers to test whether the food was acting on the gut or on the taste buds. They either got a vanilla Ensure shake, a high sugar drink, a high protein drink, or a high fat drink. Only sham feeding the high fat drink caused a response by the endocannabinoid system. The tongue tasted fat and relayed a message to the brain, which then sent word to the gut to begin producing anandamide, a potent endocannabinoid that attaches to the same receptor sites as the exogenous cannabinoids found in marijuana and, like marijuana, gives us the munchies. Since the endocannabinoids make us feel good, a food that prompts their release is a food that we are driven to eat. That’s why they’re there: to promote certain beneficial behaviors.

Okay, but can this be extrapolated to humans eating a diet of real food? I remain unconvinced. The real kicker lies in the fat that they used – it was corn oil, which is an industrially-produced food high in omega-6 linoleic acid that simply doesn’t appear in nature. If you want to extrapolate the results of this study to humans eating a diet of fried corn chips, Hostess cupcakes, and other seed oil-enriched fare, be my guest. I’d even agree with the possibility that high omega-6 junk food is inducing mindless, endocannabinoid-induced bingeing. But I’m not worried about your butter, your olive oil, or your coconut oil. Each are wildly different foods composed of various fatty acids in varying amounts. Each has a different effect on the animal that consumes it. “Fat” is not a monolith.

For some opposing takes on the study, see Emily Deans’ post and then read Don Matesz’s interesting take.

Dear Mark,

I’ve been getting this article emailed to me by multiple people.

Eating Meat Linked to Disease, Report Says

What are your thoughts on it?

Thanks,

Dan

I’ve seen this floating around, too. It’s nothing new, and I mean that quite literally: this “report” consists of old epidemiological data drawn from pre-existing studies that I’ve probably dissected before. The main thrust of the “Meat Eaters Guide” is the environmental impact of various animal foods – it was put together by the Environmental Working Group, after all – with the “health effects” tacked on.

I have a real problem with the studies that condemn meat, especially red meat, for several reasons:

1. The studies almost invariably conflate red meat, processed meat, and any food that contains meat. The headlines scream “red meat,” but the prose slips in “red and processed meat,” as if the two are interchangeable. So, red meat includes such fare as hot dogs (with white flour buns), hamburgers (with white flour buns), and Oscar Mayer bologna sandwiches. I’ve even seen studies where they include any food that employs meat as “meat,” like pizza (it’s the wafer-thin pepperoni, I guess). When they do make a distinction between fresh red meat (steaks, roasts, stews) and processed “red” meat, things look a whole lot different. Now, why didn’t the EWG include that last study in their report? For an example of what they mean by “meat,” see the photo used in today’s article up above. Is that your idea of eating meat?

2. Since red meat is a reviled, evil food, the people most likely to indulge are also doing loads of other unhealthy things, like smoking, not exercising, eating sugary junk food, eating fast food, and drinking more heavily. Primal folks are an aberration, what with their red meat-eating, heavy thinglifting, junk food-avoiding ways.

3. They rarely take cooking methods into account. The way you prepare meat can affect its potential for carcinogenicity. Overcooking at high heat is very different from braising at low heat. A burnt sausage is entirely different than a pork shoulder dressed in anti-oxidative herbs and marinated in wine.

4. They ignore the protective, anti-carcinogenic compounds inherent in meat. We know that CLA protects against cancer and we know that carnosine, an amino acid found in red meat, protects against DNA damage. Why are these never mentioned?

5. They conflate CAFO meat with grass-fed meat. The two are not the same. Grass-fed has more minerals, more CLA, and more omega-3 fats… and those are just the differences we know about! That said, I’m not even convinced conventional meat is a big health risk, especially compared to processed meat.

And that’s why I’m not alarmed, and, in my opinion, nor should you be.

Hi Mark,

My husband and I are planning to move to Ethiopia in a few months. Ethiopian food is served almost ubiquitously with injera, a spongy, sour bread-like substance made from the grain Teff. Where does Teff fall on the “grain continuum”? Just how non-Primal is it? Given how popular Ethiopian food is becoming in the U.S., I would think a post on Teff would be of interest to your readers!

Cheers,

Meredith

Teff appears to be one of the “better” grains. It contains no gluten (which is the most problematic anti-nutrient), is lower than most grains in phytic acid (which binds to minerals, making them essentially useless when eaten), and its most common incarnation – injera – is always fermented (which breaks down any residual phytic acid load). A quick look around the celiac community finds that teff is pretty popular there. If full-blown celiacs are using it, you can probably get away with some every now and again.

Whenever I eat Ethiopian, I’m the guy who asks if they use real teff flour and if the injera is fermented traditionally. Be aware: many, if not most Ethiopian restaurants now use wheat flour in their injera, since it’s cheaper than pure teff. If you ask, they’ll sometimes have traditional injera made with all teff, so be sure to ask. As teff is more readily available (and cheaper) in Ethiopia, I don’t think you have to worry about sneaky wheat when you’re living there.

So, good for an infrequent cheat, and absolutely essential when eating Ethiopian food (not necessarily because of the taste, although that too, but because the injera is used in place of silverware – to actually pick up and eat the food).

Keep the questions coming, folks. I love to answer them.

I would rebut the “Eating Meat Linked to Disease, Report Says” with the fact that not eating meat (a low cholesteral, low saturated fat diet) is conclusively linked to prostrate and breast cancer. The cynics will eat their over processed cancer-on-a-plate while I enjoy my steak.

Studies showing that eating meat is bad just crack me up. Step outside America for a moment, open up a history book and the answer is obvious. Nope.

Unless they are suggesting that what brought us as a species this far is a bad thing… but that’s a philosophical question not a physiological one.

Agreed – it makes me mad (even in The China Study) where they look at epidemiological data and generalize a portion. Does anyone think to separate out meat from grass fed and pasture raised animals from that of processed meats, meats from factory farms, those containing antibiotics and growth hormone, meat from animals fed fed feed laced with ethanol?

I swear they just want the no meat message to be conveyed. Maybe then we will eat more of their subsidized corn and wheat.

Great points on the EWG study. I thought it was excellent from a “crash-course on Grassfed” perspective and they went much further to assess many of the lesser considered contributors. However the overall thesis of “red meat is inherently bad” was really off the mark (no pun intended) on their part. The lack of clarity on the accounts of many who make these types of claims is so frustrating. I would hope that they might have the integrity or intelligence to make a differentiation between Grassfed meat and say, an OM wiener. Oh well, Rome wasn’t built in a day…

Thanks Mark. I will continue to eat my grass-fed red meat without fear of disease, and that’s good since I eat A LOT of it(I even get funny looks from the other people in the buying club when it’s delivered. What, you’ve never seen a guy get 50 lbs. of meat at a time before?)

Question on the processed meats… I eat bacon cause I love it. I cure it & smoke it myself from the one pig/year we pick up at an organic, pastured farm in Maine. So I know that we eat almost exactly 25# of bacon in a year between two of us. I also usually cure one or two hams… Adding another 10 or so #.

Thanks for the breakdown on that meat article!

Also, saturated fat is what triggers bile from the gallbladder to be dumped into the intestine to aid digestion and nutrient uptake.
Not eating enough animal fats leads to gall stones.

My mother has been eating a high fiber and sugary/insulingetic diet her entire life. She just had 3 different surgeries at the age of 67 to take 6 gallstones out of her body, the size of cherries! She’s been avoiding animal fat and red meat her entire life.

The theory of saturated fat and cholesterol from animal fats that leads to high levels of cholesterol in blood, leading to fatty deposits in the arteries and thereby resulting in a fatal condition like arteriosclerosis was popularized by a Russian named Kritchevsky, who conducted ALL these tests on RABBITS.

So wait a minute, aren’t rabbits herbivores?

Yay injera! One of the saddest parts of primal/paleo eating for me has been changing the way I eat at ethnic restaurants, and changing which restaurants I eat at. Despite living in The Mission in SF, I rarely get Mexican or papusas anymore, and I find myself sticking to just curries at thai resturants instead of noodle-based dishes. But I have been most worried about Ethiopian, since the injera is fully half of meal. While I certainly wont feast on it every week, or even once a month, I now feel like I can have the occasional special ethiopian treat… Read more »

My friend who makes her own Enjera uses a combination of teff, barley and wheat flour. She does naturally ferment the batter though. It takes 3 days to make it this way so I assume some people use shortcuts such as adding leavening agents.

I have a goat shoulder I’m planning on turning into a delicious Ehtiopian stew. I will be buying my Enjera at the store though.

It’s really a shame that the reports fail to differentiate between processed and grass fed meat. What I’m curious about is what everyone’s take is on vegetarianism being touted as more environmentally friendly? I am a meat eater myself, although I don’t generally eat it more than once a week.

“Vegetarian” is largely a meaningless term, beyond “doesn’t eat meat.” Are we talking about a vegetarian diet like Mark’s wife (who if I recall correctly eats some seafood and avoids all the foods Mark suggests we avoid) or a vegetarian eating a bunch of processed soy and other grain products? A good number of vegetarians eat food that comes from large industrialized farms. These are wreaking havok on our enviornment, destroying the natural habitats of many animal species and destroying our topsoil faster than it can be replaced–topsoil that is typically replaced by worms (which are destroyed in commercial farms)… Read more »

The body has to make sure it doesn’t get over-stuffed so it must have some feedback mechanism that kicks in. For example when you start scratching a mosquito bite it feels good and you want to keep scratching but eventually it either feels less itchy or it starts to hurt and you stop. If you didn’t stop, you’d scratch yourself raw. With the munchies you might eat or drink past your normal satiety point or even until your stomach feels bloated and uncomfortable but eventually you’re going to stretch it to its limit and be too full to want to… Read more »

I have never been known to eat a brick of butter (unless it was to make a point) but you had better get some dark meat at the start of Thanksgiving dinner or else there will be little left. Linoleic acid appears to be the binge-tastic fat. That might be a problem, since too much linoleic acid is certainly a bad thing, but nobody should be making these sorts of ridiculous extrapolations.

Just a note, if you are interested in trying Ethiopian food or teff for the first time, it can give you some really, really powerful indigestion until you get used to it.

I have the gut of a goat, and I went to have Ethiopian after not having it for a year or so, and it caused me some serious pain/discomfort.

If this happens to you, don’t write it off entirely, but give yourself a few chances to get used to it in small doses.
