The authors say the findings could help in evaluating diet guidelines to help lower blood pressure.
Connecticut-based nutritionist Samantha Heller agreed that whole grains are an important part of a healthy diet.
"Whole grains have nutrients and antioxidants that are important for good health and they help manage insulin response," Heller said. "People who eat whole grains seem to have lower incidents of diseases like diabetes," she said.
Since whole grains also help manage weight, they seem to reduce the risk of heart disease, she said.
However, Dr. Harlan M. Krumholz, the Harold H. Hines, Jr. Professor of Medicine and Epidemiology and Public Health at Yale University School of Medicine doesn't think this finding has any implications for dietary guidelines.
"This epidemiologic study is an interesting academic study but lacks any policy implications," Krumholz said. "We do not know whether enriching your diet with fiber will have any benefit on the development of hypertension," he said.
