No, I'm in agreement with the article that this meta analysis is the best data we have. It finds significant improvements for fish, dairy, and eggs vs vegans.

It's 15 years old. I'm pretty sure there is more data available today.

There's a 2012 meta-analysis of longevity which did not separate out vegans, and a 2014 meta-analysis on blood pressure which also did not separate out vegans. If you have any pointers I'm glad to look at more.

No pointers, sorry. But for fun I searched PubMed for "vegan" and it came up with 3200 hits...

Random example thought not meta.

again look at confidence bounds. Most of the studies you'll find to simply lack the statistical power to make concrete recommendations. Fish seems unambiguously good and shows the largest effect sizes vs vegans (e.g. http://archinte.jamanetwork.com/article.aspx?articleID=1710093), I agree that ovo-lacto evidence is weaker, but I'll maintain that there is slight evidence in favor of it. Given that a diet including fish, eggs, and milk, is much much easier to adhere to it remains something I recommend. Remember that my approach to nutrition in the OP is that effect sizes are small and you should focus your efforts elsewhere.

I do appreciate you taking the time to argue this point, smacking various claims with a hammer is essential.

At last, we have reached convergence! I disagree slightly (the most recent article you linked again does not find significant differences between vegans and vegetarians as far as I can tell) but I'm fine calling that "slight evidence". The problem was that the OP said:

Ovo-lacto vegetarians live significantly longer than vegans

Which doesn't sound like it's true in either the statistical nor the colloquial sense of the word. Right? So can we just remove that sentence pretty please?

Sure, seems reasonable.
