Intervention
FIRE
From baseline through 12 months of follow-up, the Mediterranean nutrition intervention group was instructed to follow a Mediterranean diet using multicomponent nutrition intervention strategies. Education was provided via an online platform, which contained brochures on Mediterranean diet recommendations, a firefighter-specific Mediterranean diet pyramid, grocery shopping tips, sample recipes, video interviews with exemplary firefighters practicing the Mediterranean diet, and access to additional resources, such as chef-led cooking demonstrations in fire station kitchens. Additional behavioral and environmental approaches were adopted to promote the Mediterranean diet in the Mediterranean nutrition intervention group, including access to supermarket discounts, free samples of Mediterranean diet foods, email announcements and reminders, and family and peer education and support.
