Primary outcomes

  1. Difference Between Interventions in Vegetable Intake

    Time frame: One meal per week for each intervention (Study weeks 1, 2, 3, and 4)

    Weight of vegetables consumed at the meal (grams)

Secondary outcomes

  1. Difference Between Interventions in Food Intake

    Time frame: One meal per week for each intervention (Study weeks 1, 2, 3, and 4)

    Weight of food (including milk) consumed at the meal (grams)

  2. Difference Between Interventions in Meal Energy Intake

    Time frame: One meal per week for each intervention (Study weeks 1, 2, 3, and 4)

    Energy consumed at the meal (kilocalories)

  3. Difference Between Interventions in Meal Energy Density

    Time frame: One meal per week for each intervention (Study weeks 1, 2, 3, and 4)

    Energy density of the food consumed at the meal (kilocalories/gram)

Other outcomes

  1. Preference of Vegetables Served at the Meal

    Time frame: Study week 5

    Preferred version of vegetables (1=standard palatability, 2=enhanced palatability)

  2. Liking of All Foods Served at the Meal

    Time frame: Study week 5

    The Yummy-Yucky Cartoon Faces Scale (1=Yucky, 2=Just Okay, and 3=Yummy)

  3. Ranking of All Foods Served at the Meal

    Time frame: Study week 5
