"Consumption of whole grains has been associated with a lower body weight and lower blood pressure," said co-author Penny Kris-Etherton, distinguished professor of nutritional sciences at Penn State. "We thought that incorporating whole grains into a heart-healthy weight loss diet may provide the same benefits to people at risk from chronic diseases."
"Results from the study showed that waist circumference and body weight decreased significantly in both groups -- between 8-11 pounds on average -- but weight loss in the abdominal region was significantly greater in the whole grain group."
