Seventh-day Adventists follow a set of dietary and lifestyle guidelines based on their interpretation of the Bible. These guidelines include abstaining from pork and blood, as well as avoiding smoking and alcohol. The avoidance of pork and blood stems from their understanding of the Old Testament dietary laws, which they believe are still relevant today. The prohibition against smoking and alcohol is rooted in their belief in promoting a healthy lifestyle, which they view as essential for spiritual well-being.
