Brief summary
The aim of this interventional study was to investigate the postprandial effect of two types of functional crackers, with 10% grape seed flour or 40% barley flour, enriched with β-glucan, in metabolic biomarkers of healthy participants.
Detailed description
A pilot cross-over, controlled, randomized and single-blinded, intervention-clinical trial was carried out, in twelve healthy men and women, aged nineteen to sixty-five years, after random allocation into the control, the grape and the barley interventional groups, received a high-fat and high-carbohydrate meal, containing wheat flour or wheat and 10% grape seed flour or wheat and 40% barley flour, enriched with β-glucan, crackers. Participants consumed the same meals, allocating in cross-over order, with 1 washout week after each trial period. Differences on the metabolism of postprandial serum total, High Density Lipoprotein (HDL-), Low Density Lipoprotein (LDL-) cholesterol, glucose, triglycerides and uric acid levels, as well as of plasma total antioxidant capacity according to Ferric Reducing Antioxidant Power method, were determined between groups in fasting, thirty minutes, one and a half hour, and three hours after meal intake.
Interventions
The crackers was enriched with 10% grape seed flour
The crackers consisted of 60% wheat flour, 40% barley flour and was enriched with β-glucans.

Intervention model description
On enrolment, all subjects were randomly assigned to the C: F1:F2 group (Control: Functional 1: Functional 2), to the F1: C: F2 group (Functional 1: Control: Functional 2) or to the F2: F1: C group (Functional 2: Functional 1: Control). Subjects in the C: F1:F2 group received the Control meal on the first visit, the Functional meal 1 on the second visit and the Functional meal 2 on the third visit; those in the F1:C:F2 group received the Functional meal 1 on the first visit, the Control meal on the second visit and the Functional meal 2 on the third visit while those in the F2:F1:C group received the Functional meal 2 on the first visit, the meal Functional meal 1 on the second visit and the Control meal on the third visit.
