Participation in the Adventist Health Study requires your valuable time and effort, and we greatly appreciate it. And your participation has real benefits. By participating in this study, you are helping to advance scientific understanding of how diet and lifestyle relate to health, longevity, and reduced risk of diseases. This study, along with other scientific studies, aims to help us all better understand how we can live longer, healthier lives. As a study member, you have the satisfaction of knowing that you have done your part to advance science and ultimately to help other people that you will never meet, some of whom may not even have been born yet. Thank you for making the effort. Participation is a service and such service is its own reward.
