In My Somewhat Informed Opinion (LOL). Olive oil is still an oil and as such it is pure fat. You can find other foodstuffs to equal it, but nothing in your fridge or pantry exceeds it for calorie-density. It's ascension to elite status in the nutritional world is perhaps related to it being part of the "Mediterranean" diet. That diet is healthful chiefly due to the heavy concentration of vegetables; healthful in spite of not due to olive oil. Indeed olive oil is not actually a food, but a concentrated food extract; it contains few vitamins and minerals and it won't by itself support life which disqualifies it as food. Finally, if one examines the diet recommendations of those physicians who have demonstrated a way of eating that will arrest, indeed reverse atherosclerotic heart disease they all seem urge (insist) their patients omit cooking oils from the diet.
