In both Australia and New Zealand, Sanitarium Health and Wellbeing Company owned by the church manufactures such brands as So Good, Up & Go and Weet-Bix. The Adventist Health Studies indicate that the average Adventist in California lives 4 to 10 years longer than the average Californian. The research concludes that Adventists live longer because they do not smoke or drink alcohol, have a day of rest every week, and maintain a healthy, low-fat vegetarian diet that is rich in nuts and beans. The cohesiveness of Adventists' social networks has also been put forward as an explanation for their extended lifespan. Dan Buettner named Loma Linda, California a "Blue Zone" of longevity, and attributes that to the large concentration of Seventh-day Adventists and their health practices. The 96,000 adults who participated in the Adventist Health Studies-2 from 2001-2007 were 30 to 112 years old, and lived in Canada and the United States. The study revealed 8% were vegans, 28% were ovo/lacto-vegetarians, 10% were pesco-vegetarians, 6% semi-vegetarian and 48% non-vegetarian. 98.9% of the participants were non-smokers and 93.4% abstained from drinking alcohol.

Those who were vegan had a lower body mass index, compared vegetarians and meat eaters.
