She didn't debunk shit.

Paleo is about consuming carb less than 25%, because that is the exact amount our body can process in a day, and the remaining 60% is protein, vitamins, fibre and so on. Paleo advocates less carb, because in the so called 21st century, we have diabetes and obesity on the rise. And carb is the real culprit to that, as most of the people consume too much carb in the name of food.

Animal fat clogs insulin receptors so that carbs cannot be processed. Ketosis is a backup emergency process, but our brain's primary and preferred fuel source is glucose.

The Libertarian Vegan Lol bullshit vegan crap. ALL fat clogs insulin flow if consumed in excess over time. However moderate fat consumption does nothing to affect this. And ketosis is a NORMAL process. If you exercise regularly or are a woman that is pregnant this happens on the daily.

Julie Wang Yes everyone is very quick to defend their viewpoint that they get triggered before actually watching the video.

Yeah, watched the video before commenting.... Her main "debunk" is that essentially Paleo is misnomer.. Something many of those authors she puts up agree on

Julie Wang no, I watched the whole thing. Also, I looked into her work and TED wasn’t the only place where she talked about it. Especially, about how she disapproves the Paleo. So, she came to the talk with her personal beliefs and vague scientific data about Paleolithic people’s usage of tools (to say the tools they found were used to grind legumes is a pretty bold statement)

Julie, you are correct. Even if Dr. Warriner stressed meat, and some Paleo Diets stress veggies - these are not the veggies the real paleolithic people would have had to eat. Our real problem today is eating too much processed food with very little fiber left in it. That's sugar, corn, soy, and wheat. She made that point. That gives us very concentrated calories with very little other good nutrients with them. And gluttony doesn't help modern man either. Our foods are 1000% more enjoyable than what men ate even 100 years ago, let alone 10,000 years ago. It's too tempting to eat nutritional bomb foods in huge quantities. I am an MD, and I run a weight loss clinic. If my patients want to eat a "Paleo Diet" that consists of a few meat/eggs/seafood daily with plenty of vegetables, that's fine. I think it sounds pretty healthy, but I'd also allow a few whole grains. But they are going to have to eat fewer calories daily if they want to lose weight.

Ian Rob added sugar is A problem, it's not THE problem

refined sugar, not "sugar"

What redeems unrefined sugar? Unrefined sugar to refined sugar is not like whole grain to white flour. While whole grain bread is a world apart from white bread, sweets or soda made from unrefined sugar are still loaded with nothing but ultra short chain carbs and not much else. You get plenty of kcals, a terrifying insulin response etc. However, I think people should relax a bit and not follow any extreme dietary fad, but I still think one should be very much aware of the composition of the foods we eat. And what refined sugar consists of is really very close to unrefined sugar. Eat the whole fruit if you want any sugar, problem solved. Or even eat two Snickers per month and forgive yourself for that "sin", while having whole grain bread, brown rice, veggies and some fish the rest of the time...

Mt Vagon Yeah she is a little biased. But I guess that adds to the reason why it's interesting to me.

Eoin Kenny It's interesting because it bias? Lol, sounds ridculous. But whatever you like man.

Well I've found it pays to be open minded about nutrition.

Eoin Kenny So first you mistakenly feel her view is unbiased, then someone points out she is biased which you concede to, but then you say that is what you find interesting, and then you declare it pays to be open minded about nutrition... But because she is biased... she isn't open minded. And she is actually very biased, she perpetuates falsehoods about our biology, and frankly with her education on the matter, I would be inclined to believe she is outright lying about it, which is a bias that cannot be trusted.

Hold on, hold on, watch again and pay attention to contradictions.

I was really hesitant myself, but I am loving this talk. She is so well educated in her field and the point is excellent. Everything I have asked myself about the paleo diet, you know, how can we KNOW? Great talk!

A couple centuries of that, and you go from the nightmare that WAS a watermelon... to something far closer to what we have today. My point is, selective breeding over millenia has led to mostly more abundant and nutrient-rich foods, and I wouldn't consider a specific cultivar - far removed from its original form - to automatically be a *bad* thing.

Me I eat organic and mostly veg, then fruit..a little meat and dairy. Simple-no processed sugars, or too much any other sugar. Less processed oils..Fruit has fiber to slow digestion of it’s natural sugar..Your taste buds can actually change without cane and processed sugar so it tastes not so good awhile after abstaining. A mention..So many diets can cause stress and eating disorders. Watch out for diet gurus..alot of money in it for them, and not clear, or even contradictory ‘research’ touted. She put on a good presentation. Makes me think of a friend who had a craving for awhile for lemons who said..I think I needed more vitamin c. Me,I related-have craving for onions with everything..so, take away the cane sugar and possibly cravings are a good thing and can lead to truly instinctual eating, and trusting what your body needs..Maybe that’s all we need and is good enough! Also, fiber can feed good bacteria in gut..lots of research coming up on that nowadays. No doubt someone will write a book saying we need MOSTLY fiber..ha!

uh thats how ted talks work

Finally, the voice of reason. Thank you, Keith, for pulling it all back together. I am a practicing dietitian and hear all about many different diets. Many that I personally either do not agree with and/or know are scientifically baloney. I do not tell patients not to follow something unless I know it is harmful. The Paleo Diet, Atkins Diet, South Beach Diet, Zone Diet, et al. People become very attached, especially if they have had success or at least no harmful results. The bottom line is recognize that "the diet" is a product to be sold in the form of a book like any other product. Rarely do facts seem to matter--whether it seems reasonable or even too good to be true. I say pick an eating plan that works for you and does not cause further harm and stick to it. Stop defending it to others like religious zealots. One way is no more "right" than another. The quickness to respond with how wrong she is is astonishing. Does anyone have her scientific background or even care or respect her depth of knowledge? What has happened to critical thinking? Keith, thanks again for your balanced response.

RDabq *_"The quickness to respond with how wrong she is is astonishing. "_* This video was posted 8 months ago... what is the appropriate time to wait before responding?

@@rdabq5991 LOL exact what happened with critical thinking; major problem with humanity!

Literally no one eats "Paleo" thinking that's really how our ancestors ate, NO ONE; the point is to eat whole, unprocessed food.

NO it explains that no historic ancestor in their right mind would have attempted to eat even one eight foot cane of sugar. But most folks I know have no problem guzzling down that large soda. It does not explain that paleo dieters eat fewer calories while feeling full.

Except not really. This talk is full of BS and pseudoscience.

See, here's my question: which Paleo diet? Is there basically just one? Or, has it become the latest and greatest marketing term from which everyone's trying to cash in on; selling their version of a diet book? I don't know, there are many basic common sense concepts in Paleo, but it seems a little too much like the soup du jour to me.

We don’t need the teeth, we have thumbs and big brains… my ancestors crafted and used spears.

And meat contains vitamin c.

Geee wonder how those Eskimo folks have been able to live for 100,000 of thousands of years

And how was the title misleading (to you)? I think it hit the nail on the head.

yeah, what was that title about? should be "Optimized Paleo Diet"

The title explained exactly what the talk was about. Smh

it's not about being PC. It is important to choose your words wisely when you are trying to spread a message. If your language turns people off, instead of inspire them, then your message falls dead in the water. There is nothing "politically correct" about choosing between "challenged" and "debunked". Neither word is presumed offensive. O.P. was just suggesting that the message would reach a wider audience with a small title change.

@Ella Blun All she basically proved is that the recently popular "paleo" diet is NOT what our ancestors ate (because it would have been impossible).Thousands of years ago, you could not have blueberries and avocados on the same plate because they naturally grow in completely different parts of the world, and transportation had not advanced far enough. You missed her entire point.

Ella Blun I don’t think she was trying to say the paleo diet was bad. She was saying that it’s just not paleo. It should be called something else. That doesn’t mean she thinks that the paleo diet is unhealthy or that you shouldn’t do it. It’s just unfortunately named badly. It misleads people. But she doesn’t ever say it’s a bad choice of diet. She was debunking the idea that paleo people ate this kind of diet - they didn’t. But that doesn’t mean we shouldn’t.

It's FAKE NEWS!!!!!

How else do you learn anything in life? Its either do the experiments/research hands on yourself or listen to the people that have already done it. Same goes for nearly everything else. Such as growing up, you can learn your lessons the hard way or listen to your parents that have already been through it.(sorry for anyone who didnt have parents or someome to raise them with love) Of corse, the best method is somewhere in between, IMO. Take into consideration what experienced people speak and also what you have found in your own experiences along the way.

Absolutely right. We also have no anatomical adaptations for eating grains, try eating wheat or barley without cooking it if you don't believe me. You can however eat raw meat if you're badass enough. Check Laurens van der Posts experiences with the Bushmen. Although fairly carnivorous, I've never followed a paleo diet or any other "fad" diet. My understanding is that they don't promote exclusive meat eating and the idea that say we should all live on red meat is a straw man.

@h. s Veganism has only existed for a little over 50 years. Meanwhile, there have been societies around the world that ate/eat a meat/animal products only diet. Which one is a fad again?

@@xzodiayinzero5929 Both. People throughout history ate anything that they could. Copralites (fossilized poop) show that in some areas pre-civilization peoples were almost vegetarian, in other areas they were almost carnivorous, in other places they ate just seafood and sea plants. We're omnivores, we eat everything.

​@@cuscof2 You don't understand my comment. I'm not talking about the nomadic hunter-gatherers that were forced to consume starchy plants when they had an unsuccessful hunt. I mean actual developed cultures where animal products were virtually the only food consumed. Even when looking at coprolites, the ones that lean towards vegetarianism don't show the full story. Typically, paleolithic people only ate plant foods as a secondary option when they couldn't get meat. Those specimen must have been during a time when there was a period of unsuccessful hunts. Omnivore doesn't mean anything.

@@xzodiayinzero5929 **Forced** to consume starchy foods? We've been eating starchy foods so long that human saliva has evolved to pre-digest it before we even swallow. Deliberately cooked tubers have been found in hearths in South Africa from over a million years ago. "animal products were virtually the only food consumed" And what did they do when everyone started dying of scurvy? Humans can't produce vitamin C, we have to get it from plants. "animal products were virtually the only food consumed" And you know this, how? I'm much more likely to take the word of professional biologists, archaeologists and paleontologists than "random Internet guy", and they're unanimous on the matter: humans are omnivores.

It's called strawman argument.

I agree. Paleo is not about meat.

Yeah, the only benefits you're getting from that is from the vegetables. The meat is just adding calories and slower digestion.

Maybe she was thinking Keto diet and doesn’t realize the difference. A lot of advertising for paleo looks really keto, so you can see how that could confuse people.

The thing is she isn't saying paleo is unhealthy. her main criticism is that to name a diet paleo when in reality it has little to do with the palaeolithic times and to sell the idea of it isn't honest. she was mainly informing on the archeology aspect of it. Another main takeaway is that grains and legumes were eaten by past humans and to exclude them from your diet without any reason is just redundant.

Stepping out of the lab, here's what Native Americans in the Southwest ate before adulteration of food supply by invading europeans. The CHART on fats is of particular interest, refuting the speak's argument. This stuff isn't rocket science. There are many, many field studies on aboriginals around the world today and what they eat.

The speaker makes many excellent points, some about Palio Diets (another fad) that are self-evident. The end of the lecture brings her best observation to light. However, some arguments aren't air-tight. She compares our digestive capacity, dentation and physiology to that of ungulates. Any archeologist in the field can immediately assign a skeleton to either Neolithic or Paleolithic eras by the condition of teeth, the shape of a skull and by diseases like tuberculosis that leave scars on bones. Nice young lady. I certainly do not advocate a mythical "Palio Diet". Balance and moderation are the keys. 

Tomas Nofziger TOo bad some of yours leaks too ;), We simply aren't designed to eat meat, we have no carnassials and our digestive track is too long ( for meat!), and we don't produce our own Vitamin C like carnivores do. Did you miss those points , making it abundantly clear we aren't designed for meat ? That was right up front. Yes , most ungulates were mainly herbivores, so was that your comment to say we aren't ? Incorrect, we certainly are, and the sooner we get to a vegan diet the sooner we'll all be much more healthy, save our global warming ridden planet and fix hunger ( most food feeds big agro). Least of all the moral side of this is SO clear. Nuff said on that point, which should be clear to anyone ( not saying you) not a troll or whom has done sufficient research to understand the underlying principles. Meat has been proven over an over again to be bad for us, same goes for milk. Its not designed for us, period. www.webmd.com/food-recipes/features/the-truth-about-red-meat “The association between consumption of red and processed meats and cancer, particularly colorectal cancer, is very consistent,” says Marji McCullough, PhD, a nutritional epidemiologist with the American Cancer Society. " After a systemic review of scientific studies, an expert panel of the World Cancer Research Fund and the American Institute for Cancer Research concluded in 2007 that “red or processed meats are convincing or probable sources of some cancers.” Their report says evidence is convincing for a link between red meat, processed meat, and colorectal cancer, and limited but suggestive for links to lung, esophageal, stomach, pancreatic, and endometrial cancers. Rashmi Sinha, PhD, the lead author of the National Cancer Institute study, points to a large number of studies that link red meat consumption with chronic diseases.

***** The vision you have for yourself is excellent. I'm not trying to change your mind. Paleolithic and contemporary aboriginal humans mostly eat organ meats, not the muscle cuts you see today in supermarkets and in restaurants. Personally, I'm not a meat eater. Yet the plants of our ancestors, including their flowers, fruits and seeds, were bitter and often toxic from lectins. WIld grains are not consumed by any contemporary aboriginal peoples.

Tomas Nofziger I really enjoyed her talk, it is good to hear other people's point of view. However, I was surprised about her comment about vitamin C. I think raw meat and fish has plenty of vitamin C. The Inuit don't get scurvy, do they?

Seriously?!? this is your take on this informative presentation? Wow, you have quite the confirmation bias based on your opinion. Here is a scientist stating unrefined diversity is historically supported and you marginalize it with your egotistical derived opinion. This is an endemic cultural problem and a reckless one when people of stature (Like you) meddle.

brolan5150 The basic diet is to eat anything that can be eaten raw (except meat, because of cross contamination, but if it came direct from an animal it technically can be) I have 2 questions, and maybe you can answer them brolan5150, why is the question of which digestive system is closest to humans not being addressed here. the only thing she covers is longer tracks for food to stay longer. Cows and most animals that eat grains and plants only have 4 stomachs!!! We have only one, like all other carnivores. That is a huge evolutionary truth! Second, the essential vitamin B12. It is only found in meat. It is not found in any plant form. Now, how did we evolve if we did not eat meat?

Marvin O The ruminant digestive system is drastically different from the carnivore system. Humans clearly have some omnivore adaptations (amylase released from the salivary glands for example), but by and large the human digestive system does not break down cellulose. Cows, as you mentioned, have four stomachs and they are teeming with specific bacteria that ferment plant matter which breaks down cellulose. Human gut length is longer than most carnivores, but nowhere close to a cow. The human gut microbiome can ferment some plant matter to an extent but nothing like a cow, sheep, goat, or horse. (which is why it's good to include veggies in your meals, not for the nutrients but to feed your good bacteria which we are learning play all sorts of roles in our health). Check out the 'expensive tissue hypothesis' which claims we became human because we ate meat (it fueled our brain growth).

Daniil Pintjuk Thanks for the big words used, made me learn having to research them. Fruits & Honey have carbs too, so the fact that you follow a "Paleo" diet does not mean you are abstaining yourself from carbs. The idea here is that you will eat everything that can be eaten raw, you may choose to cook it of course. Your "gut micro-flora" will feed off the unprocessed carbs you ingest from natural sources.

What about whole grains like oatmeal and quinoa?

Yeah she is basically saying that the "Paleo Diet" as it's advertised is anything but a paleolithic diet. Having said that, the foods that the "Paleo Diet" advocate are good for you if you eat them as whole foods and not processed. She also stressed that there is NO ONE GOOD DIET that's above the rest. The key is diversity, and avoid processed versions of food. So basically, eat healthy... lol.

she did mention that today's meat is not lean like meat was then

***** And fat found in most meats today is most certainly not that deep yellow fat either. So before you go telling people how good fat is, best take a look at that fat. Won't take long for you to see that the lipid balance in the fat is completely different. It's not even close to the same product.

DW alberta Did you see why those "experts" ranked it last? "But U.S. News & World Report's experts said the Paleo Diet was too restrictive for most people to follow long term, and that it limited some essential nutrients. They also cited a lack of research proving the Paleo Diet's cardiovascular health and weight loss benefits in their ranking." So lets see, too restrictive means it is hard to find good pasture raised meats, and NEVER EVER disrespect king corn. In other words NEVER cross big ag, they are 10 times more powerful than big oil. Limited essential nutrients? Really? I'd like to see that one. Complete BS. I guess since whole foods are not "fortified with 8 essential vitamins" that means that would disrespect big pharma too! LOLZ And lastly since when is absence of evidence the same as evidence of absence? If you don't have research papers, then do the research! Don't just claim it can't be true. DW alberta is right, pseudoscience BS.

DW alberta First off, it's CNN. I wouldn't listen to anything they have to say. Second, did you see the diet they ranked as the best? The DASH diet? They talk about Paleo being hard to follow hahahahah, that is an utter JOKE as compared to the DASH diet, where you have to count calories AND daily sodium, potassium, calcium and a couple others, and make sure you stay within this level and don't leave it.

No one is talking about diets in this comment thread...

Marc Montti rip to ur arteries

Paleo is about consuming carb less than 25%, because that is the exact amount our body can process in a day, and the remaining 60% is protein, vitamins, fibre and so on. Paleo advocates less carb, because in the so called 21st century, we have diabetes and obesity on the rise. And carb is the real culprit to that, as most of the people consume too much carb in the name of food.

Robyn Masters that's the truth. So many people healing illnesses from eating animal foods can't be false.

That's great. Also: she doesn't say at any point to stop eating paleo or even suggesting that it's bad. She's an archaeologist who's challengin the naming of the diet as Paleo, cause it's not. It's just a diet.

You were probably eating processed junk food as a vegetarian

It's well known that keto/paleo diets are good for epileptics. I'm amazed you weren't aware of that fact for so long.

The big change probably has more to do with getting rid of processed foods, not the focus on meat.

When something fails on a broad level, you don't need to go deeper. Her premise is that the Paleo diet does not represent what real paleolithic people ate. She doesn't need to know anything more than the superficial aspects of the diet to prove that. I'm really confused about what you guys were expecting. It says right in the description what she was setting out to prove. She makes no claims about the efficacy of the diet. She only disproves the logic behind it.

ZipplyZane Yeh this superficial stuff isn't a real and true representation of what the Paleo Diet is. Eating heaps and heaps of meat - that isn't the Paleo Diet I know. Our ancestors ate meat regularly, to be sure, but probably not everyday. I'm pretty sure the foraging for berries, nuts, yams, etc was far more productive than the hunting. Sometimes the hunters come back empty handed, but not the foragers. These were the every day foods. Grains and legumes, however, were certainly not an every day food as in modern diets. Starchy grains and starchy legumes do make me sick - I have a nasty immune disease called Ankylosing Spondylitis. The reaction to eating these is surprisingly fast. I can't blame people if they don't believe me.. I had heard people say this about my condition and didn't believe it for years. I thought they were fools. BUT the real reason I can digest these starchy grains and legumes is damage to my gut flora leading to improper fermentation. This is primarily due, I think, to some aspect of our modern lives. It could be preservatives, it could be antibiotics, or lack of contact with dirt from our modern cleanliness habits.. it could be all the above...

ZipplyZane There is the issue to your confusion, go deeper into what exactly? This Paleo Diet is a manufactured diet by publication companies that want books on the shelves that sell like the Scarsdale diet, or South Beach diet or Vegan diets books which are all the rage. If you rare tailoring your criticism solely on the media market, you really have not explained or countered any peer reviewed research used to promote any vegetarian, vegan, Paleo, low carb or whatever group who base their claims to promote their diets through real research.

People denying the Paleo diet are denying common sense. The logic of the diet centers on evolution. Humanity existed for 3 million years. The biggest evolution was cooking meat that led to brain evolution. Grains, legumes and dairy that came from settlement is 10,000-40,000 years ago. The argument is that 10,000-40,000 years is enough time to develop SOME tolerance to these foods through evolution. But evolution has not completely removed the digestive problems that these foods have caused. People today act like we've evolved into a completely different species and are not governed by the same laws that governed cave men.

I love that series. Was not able to finish it due to moving away from the are where the library had those books but it was riveting to read.

even normal muscle meat has vitamin c. on top of that there are other anti oxidants too. uric acid, purines(which the body uses to produce uric acid), glutamine+glycine+cystine(which the body uses to produce glutathione), taurine and others. there are alot of peopIe who dont eat alot of fruits and veg, but dont have scurvy. our ancestors too. they werent munching on plants all year round, yet they didnt go extinct from scurvy.

Robb Wolf is the last person you want to be going to for nutrition advice. His credentials are as nonexistent as his understanding of nutritional science. He's a snake oil salesman spreading nonsense in hopes that you buy his books and paleo brotein.

Frederick0220 That is a logical fallacy. You can't just discredit a person on the basis of their credentials. You must assess a person's argument on the logic and evidence behind the argument. Furthermore, while Robb Wolf has no PhD, he does have a Bachelor of Science in biochemistry, and he did work as a research assistance for 5 years, specifically in the area of lipid metabolism. So he just isn't some regular guy, with no formal background in the subject matter. Secondly, if his lack of a PhD in the subject being discussed causes you to dismiss him (again a logical fallacy), keep in mind that he buttresses his claims with the research of many people who are equally credentialed as the speaker, Dr. Christina Warinner. It would be like me stating that gravity is real, and you dismissing me because I have no PhD in physics, despite the fact that my statement about gravity is true and can be substantiated by evidence and argument from many physicist who have a PhD. Finally, by definition, a snake oil salesman sells a product or dispenses advice that doesn't really work. The fact that many people can attest to Robb Wolf's advice improving all markers of health refutes that claim. I, for one, have followed his advice, and had lost over 50lbs (and I am continuing to lose ), improved every lipid measurement (overall cholesterol, HDL, LDL, LDL particle size, triglycerides), as well as reduced my blood pressure and fasting blood sugar levels. All of this was done, by the way, without enduring the rapacious hunger that I normally experience following a conventional low fat diet. My own doctor was flabbergasted at the results. If that is what a "snake oil" salesman actually does, we need more of them.

Frederick0220 The Journal of Nutrition and Metabolism disagrees, they have employed Robb to review submitted scientific trials for accuracy before publication. He's also a research biochemist and has been invited to lecture on strength, conditioning, AND nutrition by the Marine Corp, Naval Special Warfare, Canadian Light Infantry and NASA. _They_ consider him an expert.

Primal Vegan All great points.

Registered Dietitians are fed their curriculum, via government standards, which were arrived at through dubious scientific methodology. I would argue that registered dietitians, for the most part, don't do the primary research or have familiarity with the primary research, which informs the nutritional guidelines that they are being taught in schools. Hence, most of them do not critically evaluate the science behind the information they are told to dispense. However, many researchers, like Robb Wolf (who holds an undergraduate degree in biochemistry and did research in lipid metabolism for 5 years), Dr. Loren Cordain (a professor of health who has done extensive investigations into primitive diets) Dr. Boyd Eaton (a medical doctor who has been published in medical journals with respect to hunter gather diets), and Gary Taubes(a Harvard and Columbia trained science journalist who is world renowned for his science writing, specifically in nutrition) do have to be familiar with the primary research, and are quite versed as to the flaws in the research that dietitians take as gospel. Secondly, as I mentioned above in a response to another respondent who had the same criticism, to argue that someone's position is valid or invalid, on the basis of just the degree they hold, is a logical fallacy(Argumentum ab auctoritat or argument from authority). Furthermore, take any position on any issue, and you will have equally credentialed people take opposing sides of the same issue. How would merely having a degree clarify the truth, if two people, who are equally educated in a subject, could hold contradictory opinions on that subject? However, if having an RD by your name confers upon that individual credibility, at least in your mind, then how about the following registered dietitians who advocate for the Paleo Diet or low carb diet: 1. Cassie Bjork 2. Amy Kubal 3.Melanie Thomassian 4.Kelsey Marksteiner 5.Stephanie Greunke 6. Aglaée Jacob 7. Franziska Spritzler 8. .Mary Trenda 9. Dr. Jonny Bowden (nutritionist) So, if you dismiss someone's opinion on nutrition, just because they are not a registered dietitian, then you have to contend with the seven dietitians and one nutritionist mentioned above, who all advocate for a low carb or Paleo eating model. By the way, the above mentioned seven dietitians and one nutritionist who promote a low carb/Paleo is not an exhaustive list. These are just of the few notable people. There are plenty more, and their ranks are growing.
