Adherence to a Mediterranean-style diet supplemented with extra-virgin olive oil or mixed nuts significantly reduces the risk of stroke, myocardial infarction, and cardiovascular death by approximately 30% without requiring caloric restriction or weight loss.
Adopt a Mediterranean-style eating pattern that emphasizes extra-virgin olive oil and mixed nuts. You do not need to restrict calories or lose weight to get the significant (approx. 30%) reduction in stroke and heart attack risk associated with this diet.
GoodSupportsHIGH confidence
patients randomized to unrestricted-calorie Mediterranean-style diets supplemented with extra-virgin olive oil or mixed nuts had a ≈30% reduction in the risk of stroke, myocardial infarction, and death attributable to cardiovascular causes, without changes in body weight.
Why this rating
Based on a large primary prevention trial (PREDIMED implied by description), which is high-quality evidence, though the text summarizes rather than details the full methodology.
