48g of Whole Grains Daily Cuts Blood Pressure

In a cross-over study conducted at the UK’s University of Surrey, researchers asked 14 healthy normal-weight adults to consume either two whole grain rolls (totaling 48g of whole wheat) or two control rolls with their normal diets. While researchers did not find the decrease in appetite they had been seeking, they were surprised to find a significant decrease in the subjects’ systolic blood pressure during the three weeks they ate the whole wheat rolls, and an increase in systolic pressure during the white-bread phase of the trial.
