Can a MED Diet Rich in Olive Oil Be Healthy For Heart Patients?

What is the CORDIOPREV Study?

How Did They Do the CORDIOPREV Study? 

What Patients Were in CORDIOPREV?

What Was In the 2 Diet Plans? 

Was There a Differencea in Adherence to the 2 Diets?

Was There a Difference in Outcome? 


In this large randomized study over 7 years in actual patients with heart disease, the lower-fat diet did not perform as well as the MED diet with added olive oil. Neither diet was fully plant based (vegan) and neither diet was no-oil so it is unknown if either of these would have performed better. For the patient willing to change to the MED diet, additional olive oil is not harmful and may be helpful.
