1Data represent mean ± SE. P values for ANCOVA with baseline value as covariate. There were no significant differences between groups at baseline or during the trial. 2Three day diet records were kept prior to the start of the trial (baseline), at week 1 (the first 3 days of the trial), and at week 8. 3Reduced sample sizes reflect missing diet records.
