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.
The possible relationship between diet and mortality remains an important area of investigation. Previous studies have identified dietary factors associated with mortality. Those found to correlate with reduced mortality include nuts,1- 4 fruit,5,6 cereal fiber,2 polyunsaturated fatty acids (PUFAs),2 ω-3PUFAs,3 green salad,7 Mediterranean dietary patterns,8- 11 “healthy” or “prudent” dietary patterns,10,12,13 plant-based diet scores,14 plant-based low-carbohydrate diets,15 and vegetarian diets.4,16,17 Associations with increased mortality have been found for a high glycemic load,2 meat,6,7 red meat,18,19 processed meat,18,19 eggs,7 potatoes,5 increased energy intake,20 and animal-based low-carbohydrate diets.15
Vegetarian dietary patterns may contain many of the above-listed foods and nutrients associated with reduced mortality while having reduced intakes of some foods associated with increased mortality. Vegetarian dietary patterns have been associated with reductions in risk for several chronic diseases, such as hypertension,21,22 metabolic syndrome,23 diabetes mellitus,24,25 and ischemic heart disease (IHD),17,26 which might be expected to result in lower mortality. Vegetarian diets represent common, real-world dietary patterns and are thus attractive targets for study.
Previous studies of the relationship between vegetarian dietary patterns and mortality have yielded mixed results. In the first Adventist Health Study, a study of 34 198 California Seventh-day Adventists,27 vegetarian dietary patterns were associated with reduced all-cause mortality and increased longevity.4,17 In contrast, the European Prospective Investigation into Cancer and Nutrition–Oxford (EPIC-Oxford) cohort study did not show an all-cause mortality advantage for British vegetarians (among 47 254 vegetarian and nonvegetarian participants),28 and pooled results have shown reductions only for IHD mortality.16
Our objective, in light of the potential benefits of vegetarian diets and the existing uncertainty in the literature, was to evaluate the possible association of vegetarian dietary patterns with reduced mortality in a large American cohort including many vegetarians.
