Primary Outcome Measures:
  • Total grams of snack consumed. [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    Total grams of snack consumed by participants over the 4-week study (with 1 snack per week) period will be determined by subtracting pre- and post-consumption weight of the snack provided.

Detailed Description:

In the past two decades overweight and obesity rates in children (ages 2-19) have risen from 5% to 17%, with toddlers (ages 2-5) at 10%. Among children and adolescents the consumption of low-energy-dense foods, such as fruit and vegetables (F&Vs), remain below current recommendations. Therefore, strategies to increase low-energy-dense F&V intake and decrease high-energy-dense food intake aimed at young children are essential. Antecedents, or cues, can trigger eating. Therefore, manipulating food presentation can be utilized to produce certain behaviors. Dietary variety and course sequence are two examples of this relationship. It has been well established that high dietary variety leads to greater consumption patterns compared to low DV diets in adults. High DV has only been tested with problematic foods, and not with the goal of increasing F&V intake. Additionally, serving a first course meal can act as a preload to decrease intake of the second course entrée. Dietary variety and course sequence manipulations have been experimentally tested with caloric intake goals but never with the goal of increasing F&V intake. Therefore, the purpose of this study is to determine the extent to which manipulation of dietary variety and course sequence affects fruit intake and overall energy intake in preschool-aged children.
