Many claims and studies have been done about olive oil and its health benefits. I've never actually read the studies proving its benefits and chances are neither have you. In my opinion you could get 100 times more nutritional use out of one can of black beans, a can of tuna, and a container of Redskin Spanish Peanuts, than for what nutritional use and money you'll ever get in 1 cup of olive oil, much less the bottle.
Olive oil in our cooking as we know it is a con, plain and simple! At best, it’s a novelty. A concept that's even easier to grasp here if you don’t believe me - picture your overweight relative that uses olive oil to cook pan fried chicken with the skin on or includes it in their pan of sausage lasagna! People use gobs of it in their food. That's not healthy
