How much olive oil is enough? Count your spoonfuls and see

Olive oil is the heart of Mediterranean eating, but a spoonful is 120 calories of pure fat. Is more always better?

Slide the amount to see what it adds to your day, and what swapping it for butter changes. Then see what two big studies actually found, where their limits are, and why there is no proven magic amount. The short version: olive oil in place of saturated fats looks good, and a measured spoon beats a free pour.
