The variety condition consisted of equal amounts of broccoli, carrots, and peas; across conditions, the total weight of vegetables served was kept the same.

Main effect of condition on vegetable intake (P<0.0001). Pairwise differences: carrots & peas < broccoli < variety (P<0.045).

Main effect of condition on meal intake (P<0.0001). Pairwise differences: broccoli, carrots, & peas < variety (P<0.032).

Main effect of condition on vegetable energy intake (P<0.0001). Pairwise differences: carrots < broccoli, peas, & variety (P<0.0001).
