Increased High-Density Lipoprotein Level

High evidence
Adults

Only mean serum high-density lipoprotein (HDL) concentrations significantly increased (p = 0.006), and mean total cholesterol (TC) to HDL concentration ratio significantly lowered (p = 0.02) in the DRB group compared to the control group.

Effect: Beneficial
Effect size: Small
Significant: Yes
Dose: 3 (females) or 4 (males) slices of DRB-fortified bread per day (providing ~22.7 g/day additional dietary fiber)
