Fifty-six children were included in a study that evaluated the effectiveness of a garden program designed to teach health and nutrition to second through fifth grade-level children. The specific objectives of the research project were to evaluate the effect of the program on nutritional knowledge of the benefits of eating fruit and vegetables, nutritional attitudes toward fruit and vegetables, and eating behaviors of children, specifically consumption of fruit and vegetables. Children's nutritional knowledge was measured with an 11-question multiple-choice exam based on the educational activities performed. Children's nutritional attitudes regarding fruit and vegetables were measured with a fruit and vegetable preference questionnaire, and children's eating behaviors were evaluated with an interview question asking them what they ate for a snack that day. After participating in the nutritional program, children's knowledge about the benefits of eating fruit and vegetables significantly improved, but there were no significant differences found in participants' attitude scores toward fruit and vegetables. However, the participants did report eating healthier snacks after participation in the nutritional program.

The Citrus Guide, Teaching Healthy Living Through Horticulture (Citrus Guide) is an activity guide designed to help teachers integrate nutrition education into their classrooms. The objectives of this research project were to: 1) help teachers integrate nutrition education, specifically as it relates to citrus fruit, into their curricula by using the Citrus Guide; and 2) evaluate whether students developed more positive attitudes towards citrus fruit by participating in activities from the Citrus Guide. The nutritional attitudes of 157 second through fifth grade students were measured with a citrus fruit preference questionnaire divided into two sections: one targeting citrus fruit and the other targeting citrus snacks. After participating in the activities, no differences were detected in attitudes towards citrus fruit. However, students did have more positive attitudes towards citrus snacks after participating in the activities, with female students and younger students having the greatest improvement in citrus snack attitude scores. Also, there was a direct positive correlation between more grapefruit and oranges consumed daily and students' attitudes towards citrus fruit.
