Loma Linda

Most religions have something to say about the body. Seventh-day Adventism is unusual in having made the care of it a matter of doctrine rather than of counsel, and Loma Linda is where that doctrine was given an institution. The teaching descends from Ellen G. White, who presented health reform as part of the church's message: a vegetarian diet, abstention from alcohol and tobacco, rest on the Sabbath, exercise and fresh air. The sanitarium opened at Loma Linda in 1905 grew into a medical school and hospital, and the church now runs one of the larger religiously owned health systems in the world, with hospitals and clinics on several continents. That has shaped Adventist identity outside the town as well.

Medical and nursing work became a recognised form of Adventist mission, and the church's presence in many countries began with a clinic rather than a congregation. The atlas describes this as the tradition's own teaching and as a matter of institutional history. It does not present the health teaching as medically prescriptive, and a reader should take health decisions from qualified clinical advice rather than from a reference article about a religious community. What the article records is that a church made a set of bodily practices part of its message, built the institutions to carry them, and has maintained both for more than a century.

Loma Linda has an unusual place in research because a religiously prescribed way of living happens to be well suited to study. The population is large, geographically concentrated, stable over time, and follows dietary and lifestyle rules that vary in a measurable way between members, which is why the Adventist Health Study cohorts have been followed for decades. Published analyses from Adventist Health Study 2, covering a very large cohort of North American Adventists, report associations between vegetarian dietary patterns and lower mortality within that cohort.

The atlas reports those as published findings about a studied population, not as a claim that any diet will produce any result for any individual, and it is worth being explicit that association in a cohort study is not the same thing as an established cause. Two things follow that are genuinely interesting for a reference work on religion. The first is that a religious community volunteered itself as a research subject over generations, which required an institutional commitment to the research as well as to the teaching. The second is that Loma Linda is the only such religious community named among the Blue Zones, a popular framework about longevity that has itself been contested, so the town appears in two literatures with different standards of evidence.
