I will say upfront I am biased. I went vegetarian in 1980 and vegan about 10 years later. I have never craved animal flesh for a single moment. That said, I think more people would be attracted to a veg lifestyle if those already in it presented a more attractive picture. No in-fighting based on motivation for the choice, no in-fighting for those who occasionally do eat animal-based food. Vegans are stereotyped as angry and hostile. I see potential for opposite. We are creating peace on the planet with our food choices. I'd like to see that energy extended to word choices and attitudes. Teaching by example is the best way. I'm 52 and wear the same size 3 I wore at 22 years old That makes a bigger impact on most people than videos about factory farms.

With respect, Mollyjade, I wasn't asking whether you think she's qualified to give nutrition advice. I was asking whether you think it's reasonable for an RD with no patients to assert (eg. with regard to olive oil) that Esselstyn / Novick / McDougall / Barnard / Fuhrman / Goldhamer / Campbell have all got it wrong ?

I'm aware that she admits to the health benefits of a largely plant-based diet. With regard to her stance against the health argument for veganism, the main crux of her argument seems to be that there's no evidence people have to go 100% vegan in order to reap the benefits.

As I mentioned above to another commenter, this argument seems kind of ridiculous because there's no evidence that a person smoking 2 or 3 cigarettes a week is at any greater risk of lung cancer than a non-smoker. And there's actually evidence that smokers who eat a large amount of green vegetables are at a reduced risk of lung cancer compared to non-smokers who eat only a small amount of green vegetables in their diet. So by Ginny's standards, any health professional who tells a person that they need to give up smoking 100% (or that quitting smoking is the only way to reduce lung cancer risk) is straying from the science.

Well there's definitely more "evidence" than there was when I last had this debate. But still only a couple of epidemiological studies, so not the sort of evidence that would convince someone like Ginny "Just The Facts" Messina. But for argument's sake, what if we were to play it safe and go for 2 cigarretes a MONTH ?

I can't say that I understand your point about comparing the risk of smoking to the risk of meat eating. The point I'm making is that there's a level of consumption below which the health consequences become negligible. At which point it becomes impossible to show the associated harm (in a RCT or even epidemiological setting). I'm sure you realise that such a level does exist even for smoking.

Regarding your point about opinions being based on scientific consensus and not on the work of individuals, I agree, but surely you don't think the above-mentioned doctors are just basing their opinions on the work of a few individuals.

Have you seen the number of references that Dr Campbell cites in his book The China Study ? That book includes Dr Campbell's review of hundreds of articles in the scientific literature as well as the China Project itself. I'm sure some people have been fooled by the seemingly persuasive and undeservedly well publicised criticisms of The China Study that are floating around. As well as criticisms from people like Jack and Ginny. Most if not all of which have fallen apart under closer scrutiny. And for the record, I don't think there's any scientific evidence on this planet that could withstand the scrutiny that that book has been subjected to. I'm sure that if you read it, you'll understand WHY it's been scrutinised so hard. Please also note that Dr Campbell has always been very clear about how far the evidence goes, as well as presenting a good case as to why people should go 100%.

As for olive oil, do you think these guys would recommend giving it up if they didn't think it was worth it ? Do you think they're just saying it because they think it'll make them more popular, or because they like destroying everyone's fun ? Do you think people such as Jeff Novick or Dr Barnard aren't reading all the same studies as Ginny Messina and Jack Norris ? I can guarantee you they are, and I can guarantee you that they're also evaluating the results of those articles carefully and seeing how that information fits in with what they've seen in their many years of clinical experience. And during those many years of clinical experience, I'm sure they've learned many things that aren't even IN the scientific literature (yet).

No doubt these docs sometimes resort to hyperbole-esque statements when trying to communicate their message to a brainwashed public, and maybe once in a while they might change their recommendations in line with new findings, and I know not all of them are ethical vegans, and some of them might say "plant-based" instead of vegan. But they still have a goldmine of information to offer you, and most of them risked their careers and professional circles to get that information to you. And not to have a dig, but I know a couple of ethical vegans who lament the use of the word "plant-based", and yet these same people haven't even plucked up the courage to tell their own mothers-in-law that they're vegan.

Vegan Outpreach and Ginny Messina drew a line in the sand many years ago when they said they don't think the health argument exists. And I think they made it quite clear that they wouldn't use it even if they thought it DID exist. And they don't want anyone else using it either. That indicates a strong bias in my view, and may well be clouding their judgement on these matters. And when you draw a line in the sand like that, it also means you're going to be less likely to admit you're wrong if/when that realisation comes.

You may be interested to know that Vegan Outpreach and Ginny Messina also think vegans should stop using the environmental argument:

They want this to be purely about the animals.
Although for some reason, they're happy to try and hook the public in with tasty fat-laidened food, which I find to be quite inconsistent with their values. Because that's really pandering to people's self-interest isn't it ? Just like the health argument. It's called the "taste argument". And there was me thinking it was supposed to be about the animals. And what are people going to do if they're stuck in some low-class hotel with no fancy vegan restaurant and no oven to make their vegan Pumpkin Streusel Coffee Cakes ? Might they give up on veganism if the food they're faced with isn't up to the standard they've been promised by all those taste-promoting vegans ? It's just setting them up for failure if you ask me.

Anyways, in light of the possible biases mentioned above, I'd encourage you to contact the above doctors / RD's next time you hear Jack or Ginny or anyone else criticise their work, because there may well be something that Jack and Ginny are over-looking or not wanting to face up to. And it's only fair to give these docs a chance to defend themselves.

I can tell you from first-hand experience that they're very accessible.

All the best

P.S. - I realise that I've responded to a couple of points that you didn't actually make.
