Hmmm...well I guess it's back to eating SAD, she's got a bullet proof arguement here...it's been fun Phackers!
This is an 80/20 post, 80% actual quetion and 20% - Truthiness.
Yes, I have, and I emailed her that she was playing with semantics. No one in his right mind among our group is claiming that our Paleo diet was THE Paleolithic diet. That was her sole argument, and that's not what Paleo is about, at all.
Paleo is simply a low-inflammation diet, using the Paleolithic principles as a blueprint, new research as a guide, and geared around realistic options today. For example, if we can't find an antelope, we buy beef. If we can't find wild greens, we buy broccoli -- as long as these are not inflammatory, based on research info. That's Paleo today, in the modern world. Nobody claimed around here that we're doing an exact Paleolithic diet. Her whole argument was semantics and driving the argument away from "what's best for us based on paleolithic info and modern nutrient research", and more towards "broccoli is new invention, you're not Paleo". Sure it is a new invention, but if it's more good for you than bad, then we'll eat it. Her misconceptions have no ending.
She even mentions that Paleolithic people were eating animals nose to tail. And what does she think that we do? True Paleo lifestylers (rather than the ones who join temporarily for the weight loss benefits), do eat nose to tail. And a lot of other things too.
Well, she knocked that straw-man right down. ;-)
First, "Mostly meat"? I don't know anyone following a non-low-carb paleo diet that doesn't eat mostly plants. She's debunking a version of the paleo diet that media or she made up.
Second, "paleolithic humans ate some grains and legumes" does not equal the US recommendations of 5-10 servings a day.
Third? Olive oil is not the only plant oil we can refine by pressing. There is of course coconut oil and even avocado oil, though rarer.
Fourth, modern broccoli and most brassica are one of the most common FODMAP rich foods. While we joke about broccoli being so good, but no one likes it, broccoli really hurts some people, just like milk and dairy can for some people.
Then she actually started to argue for a paleolithic inspired diet!
First, there is not one Paleo diet. No one in the paleo diet world is going to argue that -- they will agree!
Second, can we take lessons from Paleolithic? Yes --
1) Diversity of diet, and avoid processed foods and monoculture.
2) Eat fresh food and in-season foods, and don't eat preservatives as it hurts the gut microbiome.
3) Eat whole foods, don't eat for calories or macros. (The sugarcane v. soda example was great!)
Again, she is arguing for a modern paleo diet, not against it.
It appeared to me that all of her anti-paleo arguments have been seen before and discussed in depth in this forum. I think very few people here are in to reenactment. However, all of her conclusions were sound: diets vary by region, foods today contain less diversity, whole foods in season are best, we eat too much sugar.
I didn't learn anything new here or find anything against this way of eating, except think that the term 'Paleo' is a really poor way to describe our diet. I rate this talk "meh."
Neanderthals weren't our ancestors... Cro magnons were, if a Neanderthal had some grass seed in his tooth plaque 40k years ago that doesn't mean much of Anything whatsoever. The agricultural revolution was 10500 years ago, she admits to that, nobody. Is saying that we didn't ever before then have any grass seeds in out diet, that's a bogus argument.
The whole time she seems to be arguing against something, but it's not the paleo diet. If anything at the end I felt like a paleo/ancestral diet was supported by her talk. I feel like she titled it debunking the paleo diet just so she would be given a chance to speak. One of the less thought out Ted talks I've seen in my day, and I watch quite a lot of them. Guess they're just letting anyone talk now...
I don't think this girl understands what Paleo is about. It is not about eating the same foods people used to eat during Paleolithic times. I wish we could eat those foods, but, clearly, we won't be able to.
Paleo is a species specific diet.
She claims people ate legumes and grains during Paleo times. I believe her. My questions is - how did they cook those grains? Most likely, they were sprouted / fermented.
I find her presentation misleading, to say the least. Paleo IS about eating seasonal foods. Paleo IS about eating local. Paleo IS about eating the whole animal - liver and bones and all. So much for what Paleo stands for.
However, and I give it to her, at least she did not order to kill 4,000 elephants.
Well, I mean...what she ultimately recommends is exactly what I would recommend: diverse diet consisting of whole foods where the full animal is eaten.
Aside from the issues already mentioned, I will say that the sugar cane example is a bit disingenuous since she surely knows full well that they consumed as much honey as they could get their hands on. Her 1-liter of soda example contains 108 grams of sugar, equivalent to 6.75 tablespoons of honey. Not something you get every day, but certainly not out of the realm of possibility. I don't know how much we've changed domestic bees' honey-producing capabilities, but I imagine that one wild hive could easily yield that.
That's a very narrow interpretation of the paleo diet that she is 'debunking' there. To me Paleo reflects exactly those conclusions she comes to at the end, i.e. eat whole foods, eat local, seasonal, and diverse foods. That includes animal products of all kinds, though certainly not in excessive quantities, I like to think of plant foods as the main ingredient in my meals. Smothering everything in butter to me seems as non-sensical as covering everything in sugar. So I would say she makes some common sense points but they seem to rely on her own strawman version of the Paleo diet. Nothing new here.
I think it's spot on.
Yes, she focuses a on reenactment, but there are plenty of "paleo diet" practitioners who do the same so it is a fair criticism.
In her summary she provides 3 main lessons from the actual paleo diet: There is no one correct diet but dietary diversity is key, we need to eat fresh foods when possible, foods eaten should be whole foods. What's your argument with that?
I actually really liked this talk. I feel she is not debunking a paleo lifestyle, only the notion that it's the same as what hunter gatherers ate many years ago. This is something I already realized, and just as me she doesn't seem to think this is an argument to not eat healthy (see the end of the talk).
With respect, the core rationale of the Paleo Diet is "The most healthy food for us is that which we have evolved to live on. We should eat what people ate in the Paleolithic era."
She has indeed debunked this claim, demonstrating (with brand new science) that Paleo Man ate cereals etc - thing which are known to be anti-nutritious.
I think the Paleo movement has outgrown its name and its original theory has been shown to be inaccurate, having assumed that the human species has evolved in such a way that the diet it has followed for most of its history is perfectly suited to its nutritional needs. It is more likely that we have evolved to be able to survive - not necessarily with ideal nutrition - on a number of varied food sources. As long as we survive to reproductive age, the species persists.
How about a new name and a new philosophy ? The Human Diet - a diet that takes all the nutritional information available and excludes things which are bad for us and includes those which are good, in doses and concentrations that we are evolutionarily adapted to.
