Eat walnuts to lower blood pressure, new study suggests

17 May 2019

The scientists, at Pennsylvania State University in State College, explain that their study is one of the first to investigate how the properties of walnuts may affect heart health.

The results of the research, which the California Walnut Commission part funded, now appear in the Journal of the American Heart Association.

Walnuts contain a plant-based omega-3 called alpha-linolenic acid (ALA), which scientists believe has beneficial effects on blood pressure.

The researchers wanted to find out if the ALA content of walnuts contributes to improvements in heart health or if some other components of walnuts, such as polyphenols, might help control blood pressure among people at risk of cardiovascular disease.
