The results indicate that a healthy food policy at school can improve young children's diet.

Abstract:The partnership of parents, teachers, and schools is necessary to develop effective school food interventions. To gather parents" and teachers" opinions and perceptions about the school food policy, 884 parents and 70 teachers of preschoolers completed a questionnaire. School food policy is an issue of importance for parents and teachers: the majority agrees that schools should restrict the availability of snacks and soft drinks; however, to replace fruit juice and sugared milk drinks with sugarless alternatives will take special effort. Fruit is not always available at school, although parents would appreciate it. Parents of lower educational level are in general more permissive.

The goal of this study was to clarify the mechanism responsible for the catabolism of alpha-tocopherol. The vitamin, bound to albumin, was incubated with rat liver microsomes and appeared to be broken down. Optimal production of the metabolite was obtained when 1 mg of microsomal protein was incubated with 36 microM of alpha-tocopherol in the presence of 1.5 mM of NADPH. Chromatographic and mass spectrometric analyses of the metabolite led to the conclusion that it consists of an omega-acid with an opened chroman ring, although we could not perform nuclear magnetic resonance analysis to confirm this. Our data show that alpha-tocopherol is omega-oxidized to a carboxylic acid and that this process can occur in rat liver microsomes in the presence of NADPH and O2. The oxidation to the quinone structure appears to be a subsequent event that may be artifactual and/or catalyzed by a microsomal enzyme(s).
