You probably already know that foods containing whole grains are an essential part of a healthy diet. Now a new study suggests eating more bread or popcorn may help keep blood pressure in check as well.

The study in The American Journal of Clinical Nutrition found that men who ate the most whole grains were 19 percent less likely to develop hypertension than those who ate smaller amounts, according to Reuters.

Scientists say the link remained even after accounting for other factors that could affect blood pressure like fruit and vegetable intake, use of vitamins, amount of physical activity, and whether or not they were screened for high cholesterol.

The researchers say there’s evidence that whole grain consumption may also help women avoid elevated blood pressure as well.

Reuters says the most recent U.S. guidelines recommend that people get at least 3 ounces, or 85 grams, of whole grains daily.

According to the Whole Grains Council, foods containing whole grains have all the essential parts and naturally-occurring nutrients of the entire grain seed.

Whole grains have been shown to reduce the risk of heart disease, diabetes, stroke and colorectal cancer. They have also been shown to help with weight maintenance.
