Vegan diet, plant-based diet, reduced mortality, longevity??

Results  There were 2570 deaths among 73 308 participants during a mean follow-up time of 5.79 years. The mortality rate was 6.05 (95% CI, 5.82-6.29) deaths per 1000 person-years. The adjusted hazard ratio (HR) for all-cause mortality in all vegetarians combined vs nonvegetarians was 0.88 (95% CI, 0.80-0.97). The adjusted HR for all-cause mortality in vegans was 0.85 (95% CI, 0.73-1.01); in lacto-ovo–vegetarians, 0.91 (95% CI, 0.82-1.00); in pesco-vegetarians, 0.81 (95% CI, 0.69-0.94); and in semi-vegetarians, 0.92 (95% CI, 0.75-1.13) compared with nonvegetarians. Significant associations with vegetarian diets were detected for cardiovascular mortality, noncardiovascular noncancer mortality, renal mortality, and endocrine mortality. Associations in men were larger and more often significant than were those in women.

Conclusions and Relevance  Vegetarian diets are associated with lower all-cause mortality and with some reductions in cause-specific mortality. Results appeared to be more robust in males. These favorable associations should be considered carefully by those offering dietary guidance.

Healthy long-lived populations with a mainly plant-based diet (unfortunately not all vegan):
"John Robbins, in Healthy at 100: The Scientifically Proven Secrets of the World's Healthiest and Longest-Lived Peoples, describes the lifestyles and dietary patterns of the long-lived cultures of the Abkhasia of Southern Russia, the Vicalbamba Indians of the Ecuadorian Andes and the Hunza of North Pakistan.

He found that the percentage of calories they obtained daily was between 69-73% carbohydrates, 15-18% from fat and 10-13% from protein.

Overall daily calories ranged between 1,700 -1,800, while the Abkhasia ate 90% plant foods and the Vilcabamba and Hunza ate 99% plant foods.

All three ate low amounts of salt, zero sugar or processed food, and had no incidence of obesity and other common diseases.

He also discussed the Okinawa, who, though eating a more animal-based diet, had a similar lifestyle.

I highly encourage you to read this book, or if you need a taste of what it’s about, read this review of Healthy at 100, which includes a preview of the fascinating first chapter."
