“Olive oil is unhealthy because it is processed fat.”
Strong confidence because randomized cardiovascular evidence supports dietary patterns that use extra-virgin olive oil, and human evidence does not show that olive oil is unhealthy merely because oil is processed or energy-dense.
Olive oil is a food fat rich in monounsaturated fat, and it can be part of a healthy diet. Processing olives into oil does not make the oil toxic.
Olive oil is calorie-dense, so amount can matter for energy intake. That is different from saying it damages health.
Olive oil is most useful when it replaces butter, shortening or other fats higher in saturated fat, not when it is simply added without limit.
Can olive oil support heart health?
Yes. Mediterranean-style diets that use extra-virgin olive oil have reduced cardiovascular events in a major randomized trial.
You do not need to avoid olive oil because it is processed or pure fat. Use an amount that fits the meal and your goals.
Use olive oil for dressings or cooking when you enjoy it, especially in place of a higher-saturated-fat option.
