This retrospective study sought to examine the effects the institution of the Texas Public School Nutrition Policy had on trans fat intakes among middle school students between each year and by gender and ethnicity. Approximately 13,000 diet records were originally collected over a two-year period for a study that examined student lunchtime consumption following policy implementation. A series of one-factor analysis of variance and covariance was used to determine change in trans fat consumption, with significance set at p < .05.

No significant differences in trans fat intakes were seen among 6 ^th, 7^th, and 8^th graders following the implementation of the Texas Public School Nutrition Policy. There were also no significant differences in trans fat intakes among gender and ethnicity. Further research showed that consumption of milk increased as a result of the policy, while consumption of trans fat-containing desserts and fried foods decreased. A continuation of this study would provide trans fat intakes of students several years following policy implementation, with significant decreases in intake anticipated.
