Talk:Michael Greger

Bad Compromise

The last sentence in the intro, "Greger's promotion of veganism has been criticized for including exaggerated claims of health benefits and for cherry-picking research even though the vegan diet can be a healthy one" is a great example of a bad compromise, perhaps a remnant of a bygone edit-war, and I'd like to change it. However, all of my edits were reverted by Alexbrn who, in his edit notes, said "not an improvement".

I'm open to discussing the best way to improve that sentence. But first let me make the case that there's a lot of room for improvement. "even though the vegan diet can be a healthy one" is a tacky, out-of-place addition to this sentence. The main subjects of the sentence are: 1. Michael Greger's promotion of veganism and 2. Criticism of this. But the healthiness of a vegan diet is itself not the point of this sentence!

It comes across like it was written by a bipolar person in the middle of a mood swing. And I know exactly why. Critics of Dr. Greger wanted to include criticism, and proponents praise. They had a war, and they compromised by writing this atrocious sentence.

Consider the following sentences and tell me if you think they would belong in the headers of the respective persons:

"George Bush has been criticized for committing US troops to the war in Iraq by exaggerating claims of increasing regional stability, even though the war in Iraq may have led to greater regional stability."

Or, to keep things politically balanced:

"Barack Obama has been criticized for his role in promoting the Affordable Care Act by exaggerating its reduction in health care expenditures, even though the act may have reduced US health expenditures."

Or, moving beyond politics into religion:

"Jesus has been criticized for exaggerating claims of his divinity, even though he may have been the Son of God."

These are terrible sentences! And they are on par with that sentence in Dr. Greger's intro. We can do better on Wikipedia at making things sound encyclopedic rather than bipolar.

My proposed change is this: quote the article that mentions cherry-picking, and include enough of the quote that both critics and proponents will be just as satisfied (or dissatisfied) as they were for the original compromise. "There is some cherry picking of data. Of course that doesn't mean the cherries he picks are rotten; they're fine." That may be too long to include in the intro, but the nice thing about such a short article is that nothing gets "buried" in the article, so this could be moved to the next section.

Perhaps there is an even better alternative, and I'll wait for input before editing again, but Alexbrn, ANYTHING is an improvement over that wretched sentence.

WP:OTHERSTUFFEXISTS, so what. -Roxy the dog™ woof 15:45, 3 July 2016 (UTC)

I tried to fix that as well but the people who rule over this part of wikipedia would prefer to leave the cherry-picking quote out of context. As you can see from the above conversation, if they disagree with you about something, you're not getting anything changed no matter how strong a point you have or how weak theirs is. — Preceding unsigned comment added by 2600:8807:5408:6000:7D47:5396:3290:C1C2 (talk) 06:28, 5 July 2016 (UTC)

I have little motivation to improving this article when Alexbrn, who seems to be oblivious to his own agenda, keeps forcing his point of view as neutral and just reverts all edits without actual discussion. Looking through his post history, he seems to be on a crusade on this topic and has made such fine edits like this one https://en.wikipedia.org/w/index.php?title=John_A._McDougall&diff=677431201&oldid=677429048, where he decides to state the diet is "fad diet" that causes farting as general truth. The farting part was only removed after other long-time editors stepped in. He forces the exact same thing in this article where the header has criticism but doesn't tell who criticizes. I have no patience for the kind of passive-aggressive behavior he exhibits. --Sapeli (talk) 20:05, 12 August 2016 (UTC)

This sentence does not make sense. "Physician and skeptic Harriet A. Hall analyzed one of Greger's videos in which he claimed that death was largely a "food-borne illness" and wrote that while it was already generally accepted that plant-based diets with less red meat conferred health benefits, the evidence for them "is nowhere near as impressive or definitive as the true believers think".[ What does "the evidence for them" mean? Who is "them"? The evidence for whom? And what are "true believers"? I don't have a pos or neg pov, I just think this is a very awkward sentence. — Preceding unsigned comment added by 71.82.73.246 (talk) 20:57, 14 August 2016 (UTC)

Page protection

Because of the persistent disruption on this page by IPs and "fresh" accounts I now think a request for permanent semi-protecton here is in order. Do others agree? Alexbrn (talk) 18:51, 26 August 2016 (UTC)

Oui. -Roxy the dog™ bark 19:09, 26 August 2016 (UTC)

I like how you guys immediately turn to censorship when you disagree with how an edit should be handled. — Preceding unsigned comment added by Iloveinfo22 (talk • contribs) 19:14, 26 August 2016 (UTC)

Not true. You appear to be the one removing information. -Roxy the dog™ bark 21:07, 26 August 2016 (UTC)

So, essentially, you want to do the same thing to this page that you did to Dr. John McDougall's page. I noticed you had that page protected and you are cherry-picking critics that suit your own point of view over there too, when those critics are themselves controversial or not experts in the field (not only that, but their claims are unsubstantiated). McDougall has done some promising research, the latest of which shows that MS can be treated with his diet, but none of this is mentioned on his page, and with Alexbrn around, I see no reason to try to implement it. Count me along those who believe you have an agenda here which is obviously about making these plant-based doctors look like they are vegan crackpots. — Preceding unsigned comment added by Ciopenhauer (talk • contribs) 19:39, 29 August 2016 (UTC)

Plant-Based? I think it would be better if they were Evidence-Based. -Roxy the dog™ bark 16:13, 31 August 2016 (UTC)

Removal of sourced content

User: Iloveinfo22 please come and explain your objection. Thanks. Jytdog (talk) 19:10, 26 August 2016 (UTC)

The source in question is a blog post that has no credibility beyond its being on the Internet. I conceivably could create a blog post criticizing that blog post and then include my criticism in the post. I usually don't edit Wikipedia, but I saw that source as being included and felt the need to remove it since it lacks any objective credibility. — Preceding unsigned comment added by Iloveinfo22 (talk • contribs) 19:16, 26 August 2016 (UTC)

Thanks for talking here. Wikipedia content is based on Wikipedia's policies and guidelines. You are not presenting any policy/guideline based arguments. We do understand that you don't like this content, but not liking something is not a valid grounds for changing content here. This place is not a wild west. Jytdog (talk) 19:36, 26 August 2016 (UTC)

@Jytdog: This has been a perennial issue with activist IP editors showing up to remove this material. However, they happen to be completely right. The source is a blog, it does not have editorial oversight (except for outside submissions, which this piece isn't), and its use here violates WP:BLPSPS. I have floated the idea of putting this issue on WP:DRN before. Would you object to my doing that? --Sammy1339 (talk) 20:15, 26 August 2016 (UTC)

The statement is sourced to Harriet A. Hall as her opinion, it is not stated in Wikipedia's voice. She appears to be a well known skeptic and has the background to be skeptical of such claims. If this was in Wikipedia's voice I would agree it shouldn't be in there, however since it an opinion of a well known skeptic with a background in medicine it is a good counter opinion to show not everything Greger says is fully accepted in the scientific community.

The reason say; I couldn't just create a blog criticizing Harriett Hall and have it included in Wikipedia is; I am not well known for being an expert in the field. --VViking_TalkEdits 21:09, 26 August 2016 (UTC)

Yeah, but the relevant guideline here is WP:RS which states Self-published material may sometimes be acceptable when its author is an established expert whose work in the relevant field has been published by reliable third-party publications. Such material, although written by an established author, likely lacks the fact checking that publishers provide. Avoid using them to source extraordinary claims. Self-published information should never be used as a third-party source about another living person, even if the author is a well-known professional researcher or writer (see WP:Biographies of living persons § Reliable sources). --Sammy1339 (talk) 21:18, 26 August 2016 (UTC)

The issue here is that in his advocacy for veganism, Greger pushes his claims beyond what the science can support. A lot of "celebrity doctors" do that - people who rely on their medical credentials to get people to listen to them but "popularize" their message to the point where it just unsupportable. Dr Oz does this too. That is what it is, out there in the world, but here in WP we need to actually deal with the science. My preference would be that this article didn't exist at all because content that complies with Wikpedia's policies and guidelines ends up angering fans of the celebrity doctors, so we have these endless problems. So it goes. We use sources like Harriet Hall because the serious scientific literature doesn't take time to address these kinds of exaggerated statements; that is what WP:PARITY is for. Jytdog (talk) 22:02, 26 August 2016 (UTC)

Well, that's an opinion, and not necessarily an unreasonable one, but there is still no valid policy-based rationale for including this specific source. There's no exception to BLPSPS for this situation. --Sammy1339 (talk) 22:06, 26 August 2016 (UTC)

The content is written so as not to criticism him but rather the scientific validity of the claims he makes about medicine. Different things. Jytdog (talk) 22:45, 26 August 2016 (UTC)

Well, no, it refers to him. The article doesn't even mention any specific claims which demand rebuttal from a self-published expert. Anyway we are rehashing the same arguments from months ago and it's obviously not going to be productive, so I'll go ahead with DRN if you don't object. --Sammy1339 (talk) 00:16, 27 August 2016 (UTC)

It specifically refers to his "promotion of veganism". It is a kind of WP:CRYBLP to say that a person's fringe views are somehow exempt from criticism because they come from a person. If it were otherwise, you're going to be re-writing a lot of WP articles. Alexbrn (talk) 00:22, 27 August 2016 (UTC)

Alexbrn, nobody said exempt from criticism, but everyone is exempt from self-published commentary of all kinds according to the policy. Clearly you could go very far with SPS commentary on everything to do with a person, claiming it's not "about" the person. --Sammy1339 (talk) 00:34, 27 August 2016 (UTC)

You said "it refers to him". It doesn't. Anyhow this horse has been beaten to death long ago by you.[1] So I'm not proposing we re-run all that. Alexbrn (talk) 00:40, 27 August 2016 (UTC)

If it said "he is a quack" it would refer to him. It doesn't say anything like that. Jytdog (talk) 01:42, 27 August 2016 (UTC)

@Jytdog: @Alexbrn: I requested DRN, so hopefully this will be put to rest one way or the other. --Sammy1339 (talk) 02:13, 27 August 2016 (UTC)

That filing should include Viewmont Viking from above, all the editors who have removed/added this content in recent days, and should point to previous noticeboard discussions on this topic. Alexbrn (talk) 07:09, 27 August 2016 (UTC)

Thanks for pointing that out. I notified the others and amended the filing. --Sammy1339 (talk) 09:44, 27 August 2016 (UTC)

What exactly makes Harriet Hall such an expert in nutrition? This is a woman who referenced a raw food blog run by a sock puppeteer as a response to the findings of the Cornell-Oxford China Project ("the china study"). This article at one point also referenced another famous skeptic, Joe Schwarcz, which was removed when it was pointed out that Joe generally liked and recommended Michael Greger's work. A reference to the major American HMO Kaiser Permanente also wasn't allowed because it recommended Greger's website as a resource for health information. This article is biased and tries to make him out to be a quack giving unsupportable, radical diet advice. To improve the article, we could either add back in the references to Joe Schwarcz and Kaiser Permanente or remove the reference to Harriet Hall, as she can't be the only person referenced if this article is to be unbiased.

--iloveinfo22 I don't know if the issue is so much Hall's credibility as it is where her criticism was published (third-party, non-scientific blog) and if that particular blog post has enough relevance to be included in the unbiased biography of a doctor's life. I agree with you that the article is currently biased -- if we are looking for objective information about anyone on this site, we can't include snippets from critics on blogs. Looking forward to this issue getting resolved.(talk) 11:30, 31 August 2016 (UTC)

One day there will be an International Journal of Fatuous Nonsense where claims like Greger's can be debated. This is not that day. Until that day comes we're left with what we have now: noted authrities writing on websites with editorial boards. Guy (Help!) 15:36, 31 August 2016 (UTC)

Some of the stuff on nutritionfacts.org goes beyond mere "fatuous nonsense" into claims about treating and preventing cancer with turmeric. So far as I know we have no sources on this (the claim on the site, not turmeric in general) so must remain silent on this -- but it seems Hall was just scratching the surface here. Alexbrn (talk) 15:42, 31 August 2016 (UTC)

Alexbrn First of all, note the qualification: may be able to prevent and treat cancer. This is completely accurate: I had no difficulty finding sources showing that curcumin's possible chemoprotective properties have been studied for decades. [2] You could quibble about the wording, such as by suggesting that he should have gone out of his way to mention that it hasn't yet been proven in phase III clinical trials, but what on earth makes you say this is worse than fatuous nonsense? I have yet to see any evidence that Greger is a quack, other than Hall's say-so. --Sammy1339 (talk) 15:56, 31 August 2016 (UTC)

"Curcumin is a natural polyphenol derived from the plant Curcuma longa, commonly called turmeric. Extensive research over past 50 years has indicated that this polyphenol is highly pleiotropic molecule capable of preventing and treating various cancers." --Sammy1339 (talk) 16:06, 31 August 2016 (UTC)

There is no evidence eating turmeric can treat or prevent cancer, so saying it "may" on a nutrition site is kind of problematic because of the implication. One might even say it is a case of "exaggerated claims of health benefits" ... Alexbrn (talk) 16:09, 31 August 2016 (UTC)

"Kind of problematic", perhaps. But that's not what you said. You said worse than fatuous nonsense. --Sammy1339 (talk) 16:16, 31 August 2016 (UTC)

I was being understated (sorry I'm British): it is worse. Alexbrn (talk) 16:18, 31 August 2016 (UTC)

So in your view, saying something that's factually accurate and well-supported by science is worse than fatuous nonsense if it may be misunderstood by a general audience? --Sammy1339 (talk) 16:21, 31 August 2016 (UTC)

It's only "factually accurate" in a language-lawyer's sense. One can say "unicorns may exist" and be technically accurate. The idea that eating turmeric can prevent or treat cancer has zero scientific support. It is not good to mislead "a general audience" about serious diseases, no. Once again it seems Wikipedia is bang on: "exaggerated claims". Alexbrn (talk) 16:25, 31 August 2016 (UTC)

Your claim of "zero scientific support" is obviously wrong. Do a Google search, or just look at the sources I linked above. I don't agree that Greger's statements here are misleading. He extensively reports on original scientific research, and there's nothing inherently wrong with that. MEDRS does not apply to the real world. --Sammy1339 (talk) 16:29, 31 August 2016 (UTC)

Sorry, what evidence have you cited that eating turmeric prevents or treats cancer? Drawing this conclusion from primary lab research into curcumin is fallacious and if you're happy with such fallacies (which, yes, WP:MEDRS counteracts) I can see why you're such a Greger fan. By the ethical and logical standards of more considered medical thinking, however, this kind of exaggeration needs to be called out. I am doubly reassured Wikipedia's approach in this article is correct. Alexbrn (talk) 16:41, 31 August 2016 (UTC)

Please do not straw-man me. I said that Greger's claim that curcumin, which is found in turmeric, may prevent or treat certain cancers is well grounded in science, and that it is not worse than fatuous nonsense to make videos which discuss the relevant primary research. I also never said I was a Greger fan, which I am not. I take issue, however, with your treating him as though he were Dr. Oz. Given the often humorous derision you and JzG have for this fellow, it's remarkable that you can't come up with anything better than a claim which is technically accurate but may be misleading to laypeople. --Sammy1339 (talk) 16:50, 31 August 2016 (UTC)

Not straw: the claim on the site is "Consuming turmeric may also be able to help with multiple myeloma". There are some graphic pictures of cancer at work to illustrate. You've made it clear you're fine with this claim, at which point since we're veering away from what we can say in the article, I think we can just say: case closed. Personally, I am glad the adherence to policy has allowed us to produce a properly neutral article. Alexbrn (talk) 16:59, 31 August 2016 (UTC)

I just would like to note that there are many claims on that page and neither you nor I ever said anything specifically about that one. But generally I do not object to making videos on primary research, using words like "may", "indicate", "suggest", and (directly from Greger's mouth in the relevant video) "but we won't know until longer, larger studies are done." --Sammy1339 (talk) 17:12, 31 August 2016 (UTC)

"Consuming turmeric may also be able to help with multiple myeloma". You'd be fine telling that to somebody with multiple myeloma. Okay. Alexbrn (talk) 17:16, 31 August 2016 (UTC)

For the third time, you are putting words in my mouth. Context matters. I'd be fine telling anyone that the effects of curcumin on the progression of multiple myeloma have been studied and that the studies indicate a possible benefit, with the caveat that more research is necessary. That's what Greger's video claims. --Sammy1339 (talk) 17:26, 31 August 2016 (UTC)

In the EU, selling a food product with those claims is simply not permitted. Any such advertisements will be adjudicated as misleading and if pepole continue to make them then they may be prosecuted and their websites shut down. Guy (Help!) 20:14, 31 August 2016 (UTC)

Isn't the IJFN one of those predatory journals? -Roxy the dog™ bark 16:11, 31 August 2016 (UTC)

Sammy, please see your Talk page. Jytdog (talk) 18:13, 31 August 2016 (UTC)

• even this very sympathetic book review of "how not to die" notes that Greger oversells, making claims that are not supportable by science... including the very title of the book. We have couched the criticism as carefully as we can, attributing it, using a widely respected source for debunking bad scientific claims, and making sure the criticism is aimed at the validity of some of his claims, not at him. Trying to simply remove this from the article and not offering some more acceptable way (to you all) to do it, is not OK per BLP and NPOV and it is not going to happen. If you want this discussion to end, propose content and sourcing covering the same ground that you find acceptable. Jytdog (talk) 20:02, 31 August 2016 (UTC)

That's not really what the article says. The author says naive readers may misinterpret his book, whereas Greger is said to be optimistically skeptical about the results of experiments. ″Since I am not a nutritionist, I do not know whether other studies exist with different results—though Greger’s inclusion of footnoted qualifying comments are a hopeful sign. Of course, as he recognizes, many of the cited studies are small-scale one-shot affairs, so the effects might wash out on replication. His argument is that, unlike the negative side-effects associated with medications, the side-effects of, for example, eating your spinach are only positive—so why not include this or that plant food in your diet?″ In other words, there is evidence to suggest that these foods can be helpful in preventing disease, and if future research leads to a wash, at least it's unlikely to harm you anyway. There's no claim that anything is a guaranteed cure for any disease.

(edit conflict)This very source is a good example of reputably published criticism of Greger and some of his work. I have no objection to using it, with a fair summary of what it actually says about him, and not the Hall source. --Sammy1339 (talk) 20:15, 31 August 2016 (UTC)

so propose some content using it. Jytdog (talk) 20:17, 31 August 2016 (UTC)

I was in the process of doing so when I realized I am mistaken. This is from the "blog" section of Psychology Today and probably also self-published. I'll look for a reputably published review of this book, preferably from someone with a background in nutrition. There ought to be one somewhere. --Sammy1339 (talk) 20:24, 31 August 2016 (UTC)

Alright, I haven't found a scientific review, but this review says "Dr. Greger has been accused in some quarters of cherry-picking research and exaggerating the benefits of a vegan diet. But his case rests on a mountain of evidence." This would be a perfect source for inclusion of the type of claim certain editors here want... except it sounds like this was derived from Wikipedia, making it circular. This source also says "In “How Not to Die,” Dr. Greger avoids using the word “vegan” and makes a point of stating that you can still enjoy a serving of your mother’s Easter ham, so long as your regular diet revolves around vegetables, fruit, beans, nuts, spices and whole grains." And this is what I have been saying about the problem with Hall's criticism, which largely rests on an incorrect assumption that everything Greger says should be taken as promotion of veganism. --Sammy1339 (talk) 20:36, 31 August 2016 (UTC)

The issue of describing Greger's work more completely is entirely - entirely - separate from the issue of clearly stating that Greger makes exaggerated, unsupportable claims Please do not mix them. The exaggerations that Greger makes do not take an expert to identify. They are as glaring as "How not to die". This is exactly the kind of thing that serious people working in the field don't bother to address because they are trying to do work and don't have time to swat this stuff away. This is however exactly the kind of thing that serious people who devote themselves to identifying bullshit in our public discourse do call out, which is why Science-based Medicine is such an important reference for the community. Please deal with the actual issue. (and yes that reporter obviously copied WP). And stop misrepresenting Hall. She does not say that "everything Greger says should be taken as promotion of veganism" - that is as incorrect as it would be to state that everything Greger says is false. These kinds of misrepresentations are not helpful. Knock it off, and I suggest you re-read what Hall actually says. Jytdog (talk) 20:41, 31 August 2016 (UTC)

I can see why you would believe that, but I disagree. "How not to die" is a rhetorical device, obviously not meant to be taken literally. I have not actually seen one example of an unsupportable claim; the above discussion about curcumin is typical. It involves a claim which is technically accurate but may be taken as misleading. It's not clear to me at all that Greger's work is bunk, as several editors have repeatedly stated and implied. --Sammy1339 (talk) 20:45, 31 August 2016 (UTC)

Do not go offtopic. Please come up with content and sourcing that cover this ground that you find acceptable or let this go. I again suggest that you carefully read the Hall article; she points out several very clear exaggerated health claims that are not supportable. Thanks. Jytdog (talk) 20:48, 31 August 2016 (UTC)

Just to be completely clear - the scientific consensus of a healthy diet is very much plant-based (whole foods, mostly vegetables and fruit, little sugar and salt and processed food; not too much food, and getting some exercise every day) and the benefits of this are not controversial at all; people tend to be healthier in many ways who follow it. Tend to be. The issue with what Greger does is that he consistently makes claims that go way beyond that. Jytdog (talk) 20:56, 31 August 2016 (UTC)

(edit conflict) Regarding Hall, here are a couple examples of what I'm saying.

Can kidney failure be prevented and treated with a plant-based diet? He points to a study showing that diets lower in red meat and animal fat may decrease the risk of microalbuminuria. It also showed a reduced risk with low fat dairy!

But Greger doesn't say that it's necessary to eliminate dairy to get the possible result indicated by that study; Hall assumes he means this.

He cites a study concluding “Our results suggest that a decrease in meat consumption may improve weight management.” Suggest, may, decrease. Not veganism.

Harriet Hall's criticisms are also quite weak. It's been posted here before, but this blog gives a great rebuttal of her article against Greger's speech. — Preceding unsigned comment added by 2600:8807:5408:6000:44AC:9A9B:4102:1365 (talk) 21:03, 31 August 2016 (UTC)

Not every study he cites is supposed to support veganism. Hall assumes it is. --Sammy1339 (talk) 20:54, 31 August 2016 (UTC) (edit conflict)Also I fail to see how this is off-topic? We were discussing the book review, I thought, as well as why I believe the Hall source is unacceptable. I am arguing, as always, that PARITY doesn't override BLPSPS, and even if it did, it's not clear that his work is FRINGE at all. --Sammy1339 (talk) 20:54, 31 August 2016 (UTC)

argh. You are stuck on the "vegan" thing which is off topic. Please propose content and sourcing that says that Greger makes exaggerated claims about health. Jytdog (talk) 20:58, 31 August 2016 (UTC)

• OK, here is one thing Hall discusses:

Listen to the video from 6:08 to 7:08, if you like, if not I have transcribed it.

• "(scientific paper is up on the screen) We've known for 15 years that a (raises voice) single meal (lowers voice to normal) high in animal fat - sausage and egg mcmuffin was used in the original study - can paralyze our arteries (calls up graph on the screen with downward pointing, then upward pointing lines), cutting their ability to relax normally in half, within hours of eating animal products. The whole lining of our vascular tree gets inflamed and stiffens. And just as that inflammation - just as that crippling of our arteries - starts to calm down after five or six hours (pointing at graph where line starts to go up) -- - lunchtime! (pause for laughter) Right? And then we may whack our arteries with another another load of (lowers voice) meat eggs or dairy, right... (raises voice to normal) and so most people are in this chronic state of low-grade inflammation, increasing their risk of these (speeds up) inflammation-related diseases like heart disease, cancer, diabetes (slows down) um... one .. meal.. at.. a ..time."

What Hall says:

• "He cites a study showing that a single meal high in animal fat can paralyze our arteries and “cripple” them. This was a small study of 10 volunteers with no control group. It measured flow-dependent vasoactivity. It’s not clear what that means, but surely it’s an exaggeration to say that the arteries were paralyzed or crippled. It would be interesting to compare the results to those of vegans who ate a meal with an equal number of calories. And what we really want to know is whether the observed changes have any practical clinical significance."

Again this kind of debunking of bullshit in a talk by a celebrity doctor is not something that a serious nutritional scientist is going to take time to do; it is something that people at Science-Based Medicine take the time to do. It is why we use this reference across WP to discuss bogus claims people make. But like I said. Please propose content and sourcing discussing Greger's exaggerations that you find acceptable. Jytdog (talk) 21:22, 31 August 2016 (UTC)

From the posted criticism of Hall's criticism:

First of all, this is an experimental study, which involved feeding the subjects two different meals at different times, and closely monitoring their vasoreactivity for a time period after the meals, so can only be performed on a small group of people. Does she think that a research team can do this type of study on 100 or 1000 or 10,000 people at a time? Does she have any idea what it would cost in labor, funds and time to perform such a study on even 100, let alone 1000 or 10,000 people? And what would be the point anyway? Does she really think that human biology varies so much among individuals that the results would be markedly different in a larger study?

Next, she says that this study had no control group. In fact, the abstract of the study states the following: "To assess the direct effect of postprandial triglyceride-rich lipoproteins on endothelial function, an early factor in atherogenesis--10 healthy, normocholesterolemic volunteers--were studied before and for 6 hours after single isocaloric high- and low-fat meals (900 calorie; 50 and 0 g fat, respectively)"

In other words, since all 10 subjects received both treatments at different times, each of the 10 subjects served as his/her own control.</blockquote

Several of Hall's criticisms show a lack of knowledge in the field and/or ability to analyze a study properly. The fact that she comments on something Greger said or cited doesn't necessarily mean her commentary is valuable.

@Jytdog: I honestly have no idea about the science in this particular case, but here again, Hall misrepresents what he says. He doesn't only refer to that study; on the contrary, he seems to be claiming that the result is explained by subsequent studies which showed that the result was not caused by animal fat. Just look at a couple more minutes of the same video.

Really, though, we are getting into the kind of technicalities for which the following passage of WP:PRIMARY was written: " A primary source may only be used on Wikipedia to make straightforward, descriptive statements of facts that can be verified by any educated person with access to the primary source but without further, specialized knowledge." --Sammy1339 (talk) 21:37, 31 August 2016 (UTC)

To the IP: the blog you posted is definitely not a reliable source. See WP:IRS. Also I suggest creating a username if you want to be taken seriously. --Sammy1339 (talk) 21:40, 31 August 2016 (UTC)

Hall is not criticizing the paper that was cited; it is what it is. The issue is what Greger does with it - he makes broad, general claims that are not supportable by that study. The claims are bullshit. if someone added those claims, sourced to that paper, to WP it would be deleted in heartbeat. This WP article about Greger needs to discuss that he does this a lot. It is not everything he says, but he does it a lot. Again, please propose content and sourcing that you find acceptable that states that Greger make these exaggerations. I will wait to respond again, until such content and sourcing are proposed. Jytdog (talk) 21:41, 31 August 2016 (UTC)

I don't have any sourcing that can support such a claim about Greger. I'm looking, but the BLP policy is pretty clear that we cannot say whatever we like without reliable sourcing, even if editors believe it is true. --Sammy1339 (talk) 21:46, 31 August 2016 (UTC)

Sammy: The blog is at least as credible as anyone here. The point isn't that some famous nutritionist said it, it's just a criticism of Hall's reasoning that anyone would be able to see for themself and agree with. Whether I typed it, you typed it, or it was posted from another person who responded at length to Hall's analysis years ago, it's a fair response that points out her article's flaws. I also don't care about being "taken seriously" on wikipedia, but thanks.

Jyt: His claims are abviously supported by research, that's what he's reading from. You may feel that more research is necessary, but his beliefs clearly stem from scientific papers. Much of what he says are literally quotes from those papers rather than his own words, and as in this case, he cites follow-up studies for additional evidence.

• I just made this change to move this even farther away from anything that could be seen as commenting on Greger per se and more focused on his claims, and am going to post at BLPN about the objection. Jytdog (talk) 22:34, 31 August 2016 (UTC)

Reviews of How Not to Die by people in the field

I went looking for reviews by people in the field, of How Not to Die. Searched pubmed, searched the hell out of google, searched my university library. Not one. Can anybody find one? (this is kind of what i mean, about how mainstream nutrition people just ignore this kind of thing) Jytdog (talk) 00:20, 1 September 2016 (UTC)

Others?

• Searched on the blog of Marion Nestle who is the doyenne among scientists who talk straight to the public about mainstream advice about eating. no hits for Greger.
• NHS Choices - website of the public health service in the UK and often great: nothing.

- looking for independent highly reliable sources that even discuss him, and not finding anything... 00:29, 1 September 2016 (UTC)

Request for comments on SBM source

Does the blog post by Harriet A. Hall referenced in this article violate WP:BLPSPS? 00:32, 1 September 2016 (UTC)

Survey

• Yes. Self-published expert sources such as the Science-Based Medicine are covered by WP:RS which states Self-published material may sometimes be acceptable when its author is an established expert whose work in the relevant field has been published by reliable third-party publications. Such material, although written by an established author, likely lacks the fact checking that publishers provide. Avoid using them to source extraordinary claims. Self-published information should never be used as a third-party source about another living person, even if the author is a well-known professional researcher or writer (see WP:Biographies of living persons § Reliable sources). There have been two substantive objections to applying BLPSPS. One is that the blog is not self-published due to its editorial policy. However, this policy applies to outside submissions from the general public, not to the blog authors' posts, which are not subject to editorial oversight. The other is that Hall's criticism concerns claims made by Greger but not Greger himself. I believe this is transparently false. --Sammy1339 (talk) 00:40, 1 September 2016 (UTC)

Discussion

The dispute concerns the use of a blog post by Harriet Hall in the article on Michael Greger. The post comes from Science Based Medicine, a "nonprofit opinionated education and advocacy group" which applies editorial oversight to submissions from the public, but apparently not to the primary contributors, including Hall. I believe that the use of this source, in context, violates WP:BLPSPS and that the relevant section of WP:RS makes clear that self-published expert sources cannot be used for claims about a person. Other editors feel that the claim is about Greger's work, and that therefore the policy doesn't apply.

A presumption that Greger is a quack underlies this whole conversation, and the extreme derision and dismissive attitude of most of the editors involved has rendered discussion impossible. This view of Greger is flatly contradicted by another skeptic blog, which explicitly says of his advocacy work "the science was sound."[3] Now, he is an activist, openly so, and is opinionated. This blog post notes this, and also his avoidance of reporting on studies which say nice things about animal-based food. ("While there is some zealotry here, the studies that Dr. Greger enthusiastically talks about are from respected journals and merit our attention. I think his videos are worth watching, but keep in mind that there is some cherry picking of data. Of course that doesn’t mean the cherries he picks are rotten; they’re fine.") I think this is a fair criticism, and a reason to regard his work skeptically, but it's not the same as him being a crank TV doctor. In fact he is a highly cited researcher and is better credentialed in his subject area than Hall.

Hall is not wrong about the science, but it seems that her post misrepresents Greger by assuming that everything he says is part of an argument that veganism is the optimal diet. In fact, as far as I can tell, Greger never claims that the science supports the idea that veganism is healthier than low-meat diets, which it doesn't. One editor tried to change "veganism" to "a plant based diet" in this article, which was accurate to what Greger actually says, though not to the Hall source.

The Hall post is also polemical, framing Greger's work in the context of the zealotry of vegan activists he has nothing to do with. It cites a thoroughly debunked article by Steven Davis, half of whose citations are devoted to criticizing it and correcting its blatant factual errors. To me, this adds some irony.

None of this should really be necessary to mention, as BLPSPS is straightforward and unequivocal, and should end this dispute. But it explains why invoking BLPSPS here is not just a technicality. --Sammy1339 (talk) 00:33, 1 September 2016 (UTC)

RfC

User:Sammy1339. you unilaterally launched an RfC in these difs here on this page, just after I just today opened a very well publicized notice board thread to address the very question you have been raising. This is a very strange thing to do and pretty disruptive. Why did you do that? I have removed it for now. Please explain. Jytdog (talk) 00:51, 1 September 2016 (UTC)

It is not disruptive. There is no rule against opening an RfC while a noticeboard discussion is open. It is also appropriate as it was suggested in the DRN close, and it's clear that these discussions are not likely to generate consensus. I intended to open this RfC prior to the noticeboard discussions and am reopening it now. --Sammy1339 (talk) 00:53, 1 September 2016 (UTC)
