Key, Timothy J, et al., 1999 "Mortality in vegetarians and nonvegetarians: detailed findings from a collaborative analysis of 5 prospective studies" American Journal of Clinical Nutrition, Vol. 70, No. 3, 516S-524S, September 1999 http://www.ajcn.org/cgi/content/full/70/3/516S
Abstract: We combined data from 5 prospective studies to compare the death rates from common diseases of vegetarians with those of nonvegetarians with similar lifestyles. A summary of these results was reported previously; we report here more details of the findings. Data for 76172 men and women were available. Vegetarians were those who did not eat any meat or fish (n = 27808). Death rate ratios at ages 16–89 y were calculated by Poisson regression and all results were adjusted for age, sex, and smoking status. A random-effects model was used to calculate pooled estimates of effect for all studies combined. There were 8330 deaths after a mean of 10.6 y of follow-up. Mortality from ischemic heart disease was 24% lower in vegetarians than in nonvegetarians (death rate ratio: 0.76; 95% CI: 0.62, 0.94; P < 0.01). The lower mortality from ischemic heart disease among vegetarians was greater at younger ages and was restricted to those who had followed their current diet for >5 y. Further categorization of diets showed that, in comparison with regular meat eaters, mortality from ischemic heart disease was 20% lower in occasional meat eaters, 34% lower in people who ate fish but not meat, 34% lower in lactoovovegetarians, and 26% lower in vegans. There were no significant differences between vegetarians and nonvegetarians in mortality from cerebrovascular disease, stomach cancer, colorectal cancer, lung cancer, breast cancer, prostate cancer, or all other causes combined. "
Hmmm, the first thing I looked at was not backed up. It is interesting that fish and lacto eaters scored better than vegans.
mo' stuff for those who can understand it: http://www.ajcn.org/cgi/content/full/78/3/533S

Your online drink directory
Is your booze vegan?
It might seem weird at first, but your favourite drink might have more than just alcohol in it.
Brewmasters, winemakers, and distillers may include animal ingredients in their products directly, or they might use them in the processing and filtration.
These ingredients don't usually show up on the label, so the only way to find out is to ask.
The Barnivore Vegan Alcohol Directory is here to help.
Our 507 entries have been checked and double checked by the Barnivore community and are gathered here for you to enjoy, and maybe submit a check of your own.

My problem with cause-of-death studies without a corresponding life expectancy trend is detailed here.
For the record, I'm not necessarily disputing the implication that a vegetarian diet is statistically likely to result in a longer life (although I'd expect that correlation to diminish when appropriate controls are introduced), but you need to be more careful in terms of what evidence you introduce to make that argument.

... in all studies the proportion of smokers was lower among the vegetarians than the nonvegetarians. In all studies for which data were available, vegetarians had a lower mean body mass index, a lower percentage of vegetarians were current alcohol users, and a consistently higher percentage of vegetarians were high exercisers.“Most people do not do, but take refuge in theory and talk, thinking that they will become good in this way” -- Aristotle, Nicomachean Ethics, II.4

Bear in mind, when using Cause of Death studies realize this:
what they die from isn't always what kills them, just what the doctor decides to list on the Certificate of Death.
What I mean is: some doctors go by memory, some by what their nurse tells them, some by charts and some by, well...I really am not sure. They are not all equal.

Wouldn't sufficient sample size correct for that, assuming the vegans and non-vegans are using the same assortment of doctors in the same proportion?

However with the numerous other things vying for their attention, really, listing what a person has died from, short of saving them from malpractice, is the least of their concerns.
Which is why some manner of "CAD and/or COPD" is listed on the majority of Certificates of Death.
Because to some degree we all have them and can be found in any of us, in varying stages, in a post-mortem investigation.

Right, but wouldn't this apply equally to all of the study's population, regardless of their diets?
