March 23/Washington/Asian News International (ANI) -- Scientists have found that a high-fiber diet could be a critical heart-healthy lifestyle change young and middle-aged adults can make.

The study from Northwestern University Feinberg School of Medicine found adults between 20 and 59 years old with the highest fiber intake had a significantly lower estimated lifetime risk for cardiovascular disease compared to those with the lowest fiber intake.

For the study, Hongyan Ning, lead author and a statistical analyst in the department of preventive medicine at Feinberg, examined data from the National Health and Nutrition Examination Survey, a nationally representative sample of about 11,000 adults.

Ning considered diet, blood pressure, total cholesterol, smoking status and history of diabetes in survey participants and then used a formula to predict lifetime risk for cardiovascular disease.

"The results are pretty amazing. Younger (20-39 years) and middle-aged (40-59 years) adults with the highest fiber intake, compared to those with the lowest fiber intake, showed a statistically significant lower lifetime risk for cardiovascular disease," said Ning.

However, in adults 60-79 years, dietary fiber intake was not significantly associated with a reduction in lifetime risk of cardiovascular disease.

It is possible that the beneficial effect of dietary fiber may require a long period of time to achieve, and older adults may have already developed significant risk for heart disease before starting a high-fiber diet, according to Ning.

As for young and middle-aged adults, now is the time to start making fiber a big part of your daily diet, said Ning.
