It's a bit long but very interesting.
I loved that TED talk and wanted to post it here but know that some members are very passionate about being Paleo.
I haven't read any of the books in question, but I didn't get the sense that she concluded they were recommending bad diets. Just that describing them as "paleo" was not too accurate.Quote:

That was fascinating. Not so much for debunking (or not) the paleo diet, which I don't really have an opinion on one way or the other, but because it is such a joy to hear a scientist speak so well and so balanced about something she knows a lot about. And for the total lack of snappy soundbites :-)
Some of what she said towards the end really echoed what I read in "An Edible History of Humanity," that agriculture was responsible for population explosion, social stratification (i.e. income and power inequality), and poor health and quality of life, all at once. While I think there's a lot of BS floating around about what types of agriculture can or cannot sustain the global population (all of which will soon go out the window when climate change destroys current agricultural lands and practices, anyway), I don't think there's any question that the world truly cannot produce enough calories to sustain the population without massive consumption of grain.
Not having read any of the "Paleo" books either, I was under the mistaken impression that they called for getting most of one's calories from vegetables, with smaller contributions from nuts and meats. And of course, eating locally, seasonally and organically. Which is what I've really been trying to do anyway, and feeling so much better (both in terms of massively increasing meat to once or twice a week during heavy training, and in terms of greatly reducing grains and increasing vegetables).
Personally I don't really care what people ate in those days :) For me it is about how it makes me feel - I've more energy, feel younger than I have in years, and almost all of my health problems reversed themselves very quickly after adopting this approach (digestive system issues within a couple of days). There are certainly Paleo/Primal proponents who turn all of this into a religion - but for me it is all about the results. I fall more into the Primal camp myself rather than "pure" Paleo (I will consume some forms of dairy occasionally even though I am sensitive to it). To me it is all about finding what works for our specific bodies, that is what matters in the end. I tend to be more pragmatic than dogmatic ;)
I agree.Quote:

It's an interesting talk and she definitely 'debunked' a lot of the random and incorrect myths about the paleo diet.
Unfortunately, I don't think she read any of the paleo books either...at least, not any of the more modern ones. :( The three myths that she 'debunked' are not really tenants of the paleo diet at all. They are mostly just talking points from the media/internet.
1) "humans evolved to eat meat and ate it in large quantities" - humans evolved to eat omnivorously (as she points out) and the paleo diet supports this. There is a general over-abundance of media focus on the meat aspect of the paleo diet (partially to assure people that meat IS healthy). All paleo books point out that today's meat is not like our ancestors meat was and that we should either choose wild, grass-fed or extremely lean cuts when eating meat to be as healthy as possible. All paleo books also point out that our ancestors would have eaten organs and marrow too and encourage it. And not a single one says that we should eat meat to the exclusion of all else. Vegetables are a huge aspect of the diet.
2) 'paleo people did not eat whole grains or legumes' - while the paleo diet does exclude these items, it is mostly in response to the modern diet that is totally focused on them. Proof that our ancestors had tools for grinding grain or had legumes in their teeth indicates that they ate these things occasionally. Of course they did. But have you ever tried to grind grain by hand or grow and harvest beans by hand? I have. There is NO WAY our paleo ancestors ate these things in quantity...certainly not until the advent of agriculture. Do you know how long it would take to gather the grains necessary to make a single piece of bread from the wild? Hell, even if you grew them yourself in your backyard, it would take months! You can get nutrition from beans and grains but it is more readily available from veggies and fruits. If you are starving (literally) and grains or legumes are the only thing to eat, eat them. Common sense prevails here. We live in a world of abundance so we don't need to eat tree bark just because our ancestors might have had to in order to survive.
3) "the paleo diet is what our ancestor's ate" - of course it's not...not exactly. Every single paleo book out there points out the fact that foods now are totally different than foods where then. I'm not sure what books she was 'debunking' when she pointed out that our blueberries or carrots or broccoli are different due to agriculture. The paleo diet doesn't shun agriculture - if so, there would be no food to eat!
And her three points for a healthy diet? Every single paleo diet book out there includes the same three ideas 1) diversity 2) fresh and in-season and 3) whole foods.
I agree with everything she said, but she didn't really debunk anything except some of the incorrect paleo diet information floating around the media!
I see no reason for a diet to totally exclude legumes and grains.
Then you shouldn't exclude legumes or grains. :)Quote:

This! As for me, excluding all legumes and grains wiped out all of my many digestive system problems - and I am far from deprived :) I certainly don't expect others to make my choices.Quote:

I restrict my grains quite a bit and I eat a ton more vegetables than I used to. Dairy has always been limited for me. I also notice that when I am faced with a recipe that has added sugar, I leave it out. I didn't really see any change in my health, because I already knew what sets my stomach off. In the end, I think a lot of people jump on the Paleo bandwagon because it helps them control their weight. This is the nature of people. Everyone has to find what works for them. I knew I couldn't live without an occasional serving of brown rice or good whole wheat bread, or red wine. But, I have a lot more knowledge now and a lot more good recipes!
I must have missed something.Quote:

Not meant to offend!
I seem to remember reading somewhere that there's a hypothesis floating around that agriculture (of grains, at any rate) started as a way to ensure a steady supply of beer... Just throwing that out there. :D
GLC, I think some of the Paleo animosity is due to some of the more, uh, vocal Paleo people. They come off as either holier-than-thou religious fanatics, or dietary hipsters. (I think the same thing about pushy vegetarians/vegans. If someone tells me that I shouldn't eat meat, I have to resist the temptation to go buy a cheeseburger.)
I'm not entirely sure I buy the "wheat/legumes=poison" argument, either. Yes, there are people sensitive to them, but if you're not one of those people, I fail to see what the problem with eating them is. (And don't get me started on the guy claiming that gliadin acts as an opiate.)
(I may or may not be procrastinating right now...)
I'm such a lazy bum : I haven't been paying attention to the Atkins, Mediterranean, Paleo, raw food, vegan, etc. diets at all for the last few decades.
It doesn't mean I haven't changed:
* really cut down my meat to 3-4 times per month (almost vegetarian)
*cut out white rice, white bread and a lot of bread in general (abit of gluten-free, no it's more less high glycemic)
*increased eating desserts.....not good at all! :o
*drifting to lighter pastas that are low in egg yolk/none at all.
*egg whites instead of egg yolk. But sure I'll have whole eggs about once a month. I never hated eggs. I just drifted away from whole eggs for home.
*a bit bigger breakfasts daily
*consuming 2 litres of skim milk over 5 days now
*1-2 fruits daily: this has not changed over last few decades
I have not changed eating up to approx. 1.5 cups of veggies each dinner....for the past um...30 yrs. And get this: usually cooked. I seldom eat salads -- only 15% of my diet. No, it's not bad. Lots of raw veggies is not in traditional Chinese or Japanese diets. One must know how not to overcook veggies. And who wants to eat Chinese mustard greens raw? Or bitter melon eaten raw? No way. There But they are quite healthy.
Always seem to include onions, garlic and ginger root in my dinner somehow --85% of the time or more. I guess you can call that my holy trinity spices for Asian cooking.
I could do better:
more veggie consommé soups, or pureed veggie soups
No, more beans and nuts doesn't sit well with me. My stomach seems take effort to digest. Nuts for tiny snacks on a long bike ride...so have it maybe less than 8-10 times annually.
And I still haven't...had any sports food nor drinks after all these years of cycling.
Methinks the "debate" is also there because sciency types are obsessed with causality, while journalists trying to make a point just want a good story, and the rest of us just want to stay healthy. So if anyone says anything even resembling "this food is good for you because it's what we ate in the paleolithic" a paleo scientist will cringe at the "because" and proceed to debunk part 2. While the point is rather part 1 "this food is good for you", and the reason isn't particularly important.
If people feel better eating no grains, or no legumes, or no meat for that matter, more power to them.
eta: the wikipedia page on the paleo diet has a couple of points that are interesting, if not particularly appetizing...
"humans are established to conditionally require certain long-chain polyunsaturated fatty acids (LC-PUFAs), such as AA and DHA, from the diet.[109] Human LC-PUFA requirements are much greater than chimpanzees' because of humans' larger brain mass, and humans' abilities to synthesize them from other nutrients are poor, suggesting readily available external sources.[110] Pregnant and lactating females require 100 mg of DHA per day.[111] But LC-PUFAs are almost nonexistent in plants and in most tissues of warm-climate animals.
The main sources of DHA in the modern human diet are fish and the fatty organs of animals, such as brains, eyes and viscera; microalgae is a plant-based source. Despite the general shortage of evidence for extensive fishing, thought to require relatively sophisticated tools which have become available only in the last 30–50 thousand years, it has been argued that exploitation of coastal fauna somehow provided hominids with abundant LC-PUFAs.[110] Alternatively, it has been proposed that early hominids frequently scavenged predators' kills and consumed parts which were left untouched by predators, most commonly the brain, which is very high in AA and DHA.[111] Just 100 g of scavenged African ruminant brain matter provide more DHA than is consumed by a typical modern U.S. adult in the course of a week."
;)
That is my approach, as I said above, I don't really care about the "because". I initially decided to try Paleo because I knew others who had been able to heal a problem gut with it - I had already lost most of my weight at that point. It worked so well and I just feel so darn good eating this way that I will never go back to a conventional diet.Quote:

I've had interesting reactions from friends at my change of 'diet' (I don't consider it to BE a diet, just eating well sourced, unprocessed real food), and have even had a former friend react with anger when she saw me eating what she considered to be unhealthy. I am no longer afraid of fat - as long as it is good, well sourced and unrefined (I do keep track of my macros so I don't over-consume).
She became totally offended when she saw me eat a fatty cut of meat and, to make matters worse, I turned down what she considered a "gourmet" dessert at the restaurant. I forget what it was but it was loaded with fake ingredients and sugar - both of which I avoid. If I am going to have a dessert, it is going to be made of high quality real ingredients. Part of me wonders if my different food choices led to her feeling like I was judging her choices - that is the only explanation that makes sense. I made no big deal of it, I simply ordered and focused on our conversation. I wasn't "preaching Paleo" as some do. While this was the most extreme example of this I've seen, I've seen milder versions of this a couple of other times.
Yeah, that's how I feel about eating raw, too.
Raw foodies can be so preachy that it's hard to even find a cookbook that has more recipes than preaching. (Which is seriously part of the reason I don't do anything more than salads and smoothies at home ... while I do most of my cooked recipes from the internet, that's because I already have a foundation of techniques and ingredient properties. When I'm learning something entirely new I really prefer a paper cookbook.)
But I feel SO much better after a raw meal that I don't care about the theory.
But oh, that's "anecdotal," unscientific, and what my body is telling me couldn't possibly be true. I'd better listen to advertising from Monsanto, IBP and ADM about what food is good for me.
The other question is, "coming from what?" Now, I don't follow the "what do you eat" threads at all, so I may be completely wrong, but it seems to me that athletes of necessity, especially as we get past our impressionable youth, learn to turn down the volume of the advertising and listen more closely to our bodies - doing so is the only way we keep going over the long term. And yet, here are two of us in this thread who've made huge changes to our meat consumption to wind up in a similar place ... Shootingstar "really cut down my meat to 3-4 times per month (almost vegetarian)" ... while I massively INcreased my meat consumption to 3-4 times per month (more during a marathon buildup, and I consider it the farthest thing in the world from vegetarian). :)
I get the same reaction to what I eat from my "regular" friends, no matter that it's no specific diet. Everyone is always watching my plate. At work, it's a lot of "You make your lunches? Oh, no wonder you're so healthy," and blah, blah, blah.
And they wonder why I don't give any reaction when my really good friend and her husband, who are both grossly overweight tell me they are going on the "fat flush" diet. Her husband lost about 30 pounds on this 2 years ago, and was making great progress when he just stopped. My friend believes that eating only grapes all day makes her lose weight.
Oy.
:D :p I used to eat some meat for 80% suppers or lunches daily. That's how I grew up. So I consider it alot less meat. I don't miss it alot. Eating alot of meat in 1 sitting, especially beef seems to require effort for my stomach to digest.Quote:

It probably does..... at about 60-65 calories a cup, you'd be hard pressed to eat enough of them to meet the calorie needs of a typical adult... (if you require 2,000 per day that would be 33 cups...) That doesn't necessarily mean it's a good or healthy way to lose weight. A friend of mine was telling me about some supplement (not as a believer)- take it and eat 700 calories a day and you'll lose weight!! Well duh.... eat only 700 calories a day and anyone would lose weight....Quote:

Everyone needs to drink the way I do - bottle of champagne every weekend, sometimes two - and only good champagne. :D And you can't have any more beer!

I am joking of course.
I get this a lot too. Particularly when eating with new people (ie. people I somewhat know but don't eat meals with that often). When I am asked to defend my choices (which is so not fair!) and my reasoning is because I feel better, that's apparently not good enough for some people. I think that religious beliefs, weight loss or allergies are all 'good reasons' but 'because I feel better eating this way' is not. :( I think that for some people, my not having a 'real' reason makes my choices look like a judgement on theirs (which it isn't!). Luckily, it's definitely not everyone...not by a long shot. In general, people are mildly curious or like most people who know me well, totally uninterested in my choices. After two years, they've gotten used to me. Some even find it amusing to watch me order at restaurants! :pQuote:

It certainly can be a hell of a touchy subject though.
V - I don't like champagne. Can I sub in just regular wine? If so, I'm in. :)
Veronica, I knew there was a reason I liked you!
Eden, I guess I should have clarified; my friend eats grapes all day and then eats a regular dinner. And, methinks some secret night time eating, too.
As a scientist (or a wanna-be scientist, depending on your point of view), I disagree. ;)Quote:

"Because" starts in elementary school. It's the third most common answer students give. The most common is a shrug of the shoulders, followed by "I don't know."Quote:

When I was watching the video (see original post), I kept thinking "you could say this about the macrobiotic diet fad too". That is, I don't know if they ever claimed this is what we "evolved" to eat but the point about our gut length & dental structure indicating that we are omnivores, applies to either extreme.
I should package my opinion and sell it as the latest diet fad. My opinion is that there is no one right diet for everyone--and I don't think you can predict your best diet based on your blood type anymore than your zodiac sign. You figure out your best diet based on trial & error. More meat and less carbs will work for some people, less meat will work for others. The one thing that I do think is true for everyone is that we all eat too much sugar & HFCS, and processed foods with weird chemicals. (And by "we all" I mean everyone except those few who have super will power.)
Nah, it'll never catch on. Too sensible!
Because we are conditioned from early childhood NOT to pay attention to what makes us feel better ... and in fact to accept many things that make us feel worse. If you think that something makes you feel better, but a doctor or religious authority didn't tell you that, you must be wrong!Quote:
