Moderate intake of olive oil, a mainstay of the Mediterranean diet,
was successful in reducing the blood pressure of healthy men who
don't usually eat a Med-type diet, suggests a new study.
Walnuts, a rich source of omega-3 alpha-linolenic acid (ALA), could
improve artery function and heart health and may be more important
in a Mediterranean-type diet than olive oil, suggests a small study
from Spain.
