Eating lots of whole grains could ward off high blood pressure, according to a study in the American Journal of Clinical Nutrition.
In the study, men with the highest whole-grain consumption were 19 percent less likely to develop high blood pressure than men who ate the least amount of whole grains.
While refining grains removes their outer coating, whole grains retain their bran and germ, so they are richer in many nutrients, Dr. Alan J. Flint of the Harvard School of Public Health in Boston and his colleagues note in their report.
The most recent US guidelines recommend that people get at least 3 ounces, or 85 grams, of whole grains daily, and that they consume at least half of their grains as whole grains.
