Average daily intakes of margarine (A), chow (B), and energy derived from all food sources (C), and BW (D) of B6 and 129 mice in Experiment 5. Vertical bars represent S.E.M. On Week 0, all mice had only chow to eat. On Weeks 1–10, margarine groups had margarine in addition to chow. Significant differences between control and margarine-exposed mice are indicated by * (B6 mice) or + (129 mice); P < .05; post hoc tests, ANOVA with BW before access to margarine (Week 0) as a covariate (A–C) or with no covariates (D).
