Population: 117,673 participants from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial cohort study.
"By diet group, there were 116,894 omnivores (whose diet does not exclude animal products), 329 lacto- and/or ovo-vegetarians (whose diet excludes meat, but includes dairy and/or eggs), 310 pesco-vegetarians (whose diet excludes meat except for fish and seafood) and 140 vegans (whose diet excludes all animal products)."
"After an average follow-up of 18 years, 39,763 participants were deceased."
All-cause mortality risk compared to the omnivore group:
19% less for the pesco-vegetarian group
1% less for the lacto- and/or ovo-vegetarian group
27% greater for the vegan group.
I would have liked to see the vegan group split into low/high fat.
Yikes. Don't tell Dr. Michael Gregor. Worse for vegan. It sounds like the fish eaters won. I do wonder if the vegans lost because of the processed vegan foods and vegan meats.
Isn't a pesco-vegan a contradiction in terms? Vegan means no animal (including fish) products at all. If you add fish back, doesn't it become a pesco-vegetarian?
Hi Patrick! After switching to a complete plant based diet in 2018 I’ve changed my diet again couple of months ago and added fish. This decision was on one hand based on a couple of studies showing that vegans miss more than B12 and I didn’t want to add tons of supplements. On the other hand on a study which I read here in this forum about the positive influence of fish for the prevention / slow down of metastasis growth of PC. And last but not least I always enjoyed eating fish.
The abstract of the study you posted today fuels my decision. Taking into account that the different groups differ enormously in size, the result for the „vegan + fish“ group is quite promising. And as you said, there are so many ways of being vegan, that this vegan group looks more homogeneous than it actually might me. I use to say: drinking a bottle of vodka and eating white baguette plus tons of chocolate is also vegan, but far away from healthy. So a subgroup of people following a more healthy vegan diet plus fish and sea fruits might perform even better. Thx for posting and enjoy your Sunday.
