Whole grains help reduce the risk of heart disease

Whole grain diet may help to significantly lower the risk of heart disease in overweight and obese adults who are under the age of 50, finds a new study.


Findings, published in the journal Nutrition is a key regulator of blood pressure may be whole grain nutrition and an effective strategy to reduce cardiovascular death and disease that can deliver.

“Heart disease and stroke is the leading cause of death. This study has shown that eating whole grains can lower the risk of heart disease,” metabolic Translational Research Center Director Dr. John Kirwan.

In the study, a group of 33 overweight and obese adults followed a whole grain diet (intervention) or a refined grain diet (control) for two eight-week periods.

The diets were exactly the same, except for their content of whole grains or refined grains. At the beginning and end of each diet period, participants spent three days undergoing metabolic testing in a clinical research setting.

Participants taking antihypertensive medication were instructed to maintain medication usage throughout the study.

While on the whole grain diet, participants saw a three-fold improvement in diastolic blood pressure (the lowest pressure when your heart relaxes between beats) compared to the refined grain diet.

This improvement equates to reducing the risk of death from heart disease by almost one-third and the risk of death from a stroke by two-fifths.

“This level of control can only be performed for small numbers and provides the essential empirical data that cannot be obtained from large observational studies. These evidence-based data demonstrate the effect of diet on cardiovascular disease outcomes, particularly diastolic blood pressure,” Kirwan added.
