In painting a religion as unknown, Trump seemed to suggest there must be something amiss about Carson's faith. Carson has credited his Christian faith, and Adventism in particular, for shaping his worldview and contributing to his success in life.
Trump probably isn't alone in not knowing much, or anything, about the Seventh-day Adventist Church, a Christian movement organized 152 years ago in Battle Creek, Mich., which claims 19 million members around the world, of which a little more than one million live in the U.S.
The Adventist lifestyle, which encourages abstinence from alcohol, tobacco, caffeine and meat, is credited with extending lifespan. On average, studies including the famous "Blue Zone" project reveal, Seventh-day Adventists who follow the guidelines live seven years longer than the general population.
