Extra virgin olive oil (EVOO) is considered by many nutritionists a medicine by itself, with its polyphenols it is a protective food from many ailments. Besides, it makes the veggies taste better and fills you up staving off hunger.
If it is of good quality, 2-3 tablespoons and more is not much. Watch out though, I know that in America frauds are common, especially when Italian EVOO is concerned. EVOO is a main ingredient of my own diet and I can testify to its many benefits.
