Objectives: The purpose of this pilot project was to evaluate the effect of the Improving Children's Health through Farming, Food, and Fitness Program (CHF3) on the dietary knowledge and habits of participating children. Methods: The CHF3 program aims to 1) establish salad bars and integrate nutrition messages into cafeteria activities; 2) develop and incorporate education curricula and activity guides that link program components to the education Content Standards for California Public Schools by subject and grade; 3) integrate a garden "laboratory" with nutrition education to improve children's knowledge of nutrition and improve their food choices; and 4) develop a food-waste composting system in an effort to reduce the lunch waste stream and engage students in the ongoing practice of recycling. This program was implemented in kindergarten classrooms at Rock Creek Elementary School in Auburn, California (n = 32 students) and fourth and fifth grade classrooms at American Union Elementary School in Fresno, California (n = 51 students). Results: Our findings demonstrate that the CHF3 Program can increase awareness about the importance of proper nutrition and exercise among students, teachers, and staff while increasing nutrition knowledge and improving lifestyle choices. Application to Child Nutrition Professionals: Other professionals may find their obesity prevention efforts to be more effective if they use a multi-faceted program like the CHF3 program.
