Longevity Residents in Loma Linda have one of the highest rates of
longevity in the United States. Writer
Dan Buettner has labeled Loma Linda a
Blue Zone, an area where the longevity is appreciably higher than the national average and a substantial proportion of the population lives past 100 years. Buettner's 2008 book, ''The Blue Zones: Lessons for Living Longer From the People Who've Lived the Longest'', attributes Loma Linda's longevity rate to
Adventist cultural health and diet practices. The city strictly controls the sale of alcohol and has banned public smoking. The church-owned grocery store does not sell meat. ==Government==
