Adventists often forego meat and dairy products and adhere to a "biblical diet," or the way people ate thousands of years ago. They also take regular supplements that include vitamin D and calcium - both of which are required for strong bones. The reason why Adventists tend to be healthier and live longer is because they often seek out health care when needed. Since most Adventists follow this religious practice, they're more likely to get checked by a doctor and receive necessary treatment if they do develop cancer. Additionally, Adventists believe that illness is caused by sin, and so when they are sick, they will seek medical help rather than try to cure themselves with herbs or support from friends and family. This leads them to live longer and healthier lives compared to people who don't follow this religion. Seventh-day Adventists began in the United States in 1872 when eight young men decided to devote their lives to God every Saturday. Today, there are over 6 million Adventists around the world, with several hundred thousand living in the United States. They have many different institutions across the country where they provide food for the homeless, deliver messages via radio, and much more. The largest division within Adventism is called the "Church of South Africa".
