Title: Feeding America's Bravest: Mediterranean Diet-Based Interventions to Change Firefighters' Eating Habits and Improve Cardiovascular Risk Profiles
Brief Summary: The purpose of this study is to modify the food culture of the fire service by motivating firefighters and their families to incorporate Mediterranean diet principles at work and home through behavior change strategies that involve education, participation and incentives.
