Head Start classrooms will receive "New Foods Take Time", a series of five interactive weekly lessons designed to promote children's willingness to try new foods, particularly fruits and vegetables. Lessons will be delivered by nutrition educations. Children will also receive three tastings per week of the new foods discussed during the lessons.

New Foods Take Time is a series of 5 classroom lessons focused on increasing children's willingness to try fruits and vegetables.

Children will be presented with small portions of familiar and novel fruits and vegetables and be asked if they would like to taste them

For foods that children agree to taste, they will be asked to rate their liking of them on a three point likert-type scale ("Yummy", "Just ok", or "Yucky")

Children will be presented with a series pairs of drawings with descriptions (e.g., "This boy likes to try new foods" and "This boy does not like to try new foods") and asked to select which is most like them.

Teachers will complete a questionnaire with scaled and open-ended questions about the feasibility and acceptability of the intervention

Height and weight will be measured and used to calculate body mass index (BMI). Age and sex specific percentiles/z-scores will be calculated using CDC growth standards.
