Simon is more willing than any other nutrition commentator to go wherever the data takes him. I think the truth is that there are downsides to every diet. The goal is to balance the trade-offs.

Awesome conversation, I took notes. I am an SDA and I have been vegetarian for 44 years and vegan for 30 years. I am in perfect health but I am going to be careful with my Omega 6 intake. I already use B12 and DHA/EPA supplements. I love your podcast, thanks Simon.

@Jesse47249 5 месяцев назад

Dude, it must have been hard to be a vegan back then! I truly admire you for being so consistent! Regarding supplements: B12 it's an indispensable one for vegans and I've started taking DHA recently, I've read that taking DHA and EPA together can negate each other benefits... So I only take DHA mainly for brain health. Vitamin D combined with K2 is a good one too but I don't take it because I'm vegan but because I don't get enough sun exposure.

@@Jesse47249 Vegan in the 1990s? The funny thing is, back in the 80s & 90s, vegan foods were actually better, i.e. high quality, whole food, almost zero processed junk & a greater concern about the ethics. The big corporations hadn't started to gear up to exploit the vegan market year so far more was fresh, local, hand made, fair trade, organic etc. Veganism was a social movement, not a marketplace.

Why does Dr. Greger’s and the Sherzais’s analysis of the same data find in favor of a vegan or plant exclusive diet? And there needs to be data differentiating whole food plant based and vegan.

If these neurological issues in vegans are a real problem, and not some statistical mistake, I wonder if it was more of a B12 issue rather than omega 3. The fact that Fraser mentions vegans AND LOW dairy vegetarians would seem to point more to B12 than to omega 3. Dairy is not a great source of omega 3. I wonder if the vegans were not supplementing with B12 and got very low over many years. This study on vegan Adventists, where 15% were not supplementing adequately, supports my point: doi: 10.1093/cdn/nzaa008

The few people (about 16 vegetarians) that had problems only had mild memory loss, with many having only very mild memory loss. It may have been that people switched to a vegan diet because they were already experiencing health issues. We don't know their B12 status. We don't really know what they eating. We don't know if they chose to be part of the study because they were having problems (pre-selection bias).

I have some controversial thoughts about this video. Firstly, vegetarians do get some DHA from eggs and dairy, and the maximum amount the brain and eyes can accumulate DHA is up to 5mg daily. Even one egg provides approximately 30mg of DHA, which is more than sufficient to avoid deficiency. So, I don't think that those neurological issues are due to DHA deficiency.

As a vegan, I think we should always err on the most conservative side of caution & not make unrealistic health claims for the lifestyle in the way that, e.g. the raw or fruitarian movements do. One question that comes to my mind is, given that the vegan movement remains a young movement, young in the age of the movement rather than the individuals, how can we make any claims at all regardingly longevity, "all cause mortality" etc? How much of any vegan's health is based not just on their genes, but also their pre-vegan heealth status which may be statistically good or bad, e.g. the difference betweeen those with robust health coming in for the sake of ethics, & those with poor health coming in for the sake of perceived health benefits. Until we have a significant number of 'born vegans', we really have no grounds to make any such claims.

Non meat eaters are probably getting a bit much carbohydrate. Converting the sugar in milk (lactose) to lactase through fermentation must make a huge difference. Also converting the gluten through fermentation must make a big difference. Not only eliminating these things, but the now available microbes and enzymes must be hugely beneficial. Also take the vegetarians out of the mix that gorge on pizza every second day would have to change the outcome a lot. Add in vegetarians that eat eggs, that the hens have been fed high amounts of purslane, to get the omega 3's, where the hen has done some conversion of ALA. Also adding flaxseed oil to curried eggs you can't really taste the awful omega 3. Shit why do I care, I am omnivore. Lol.
