Olive, canola, corn, peanut, safflower, sunflower, sesame, grapeseed, almond etc. are all "vegetable oil." There are many different types of vegetable oils, each with their own flavor and smoke point. And, like Andy said, all with the same amout of fat and zero cholesterol.
Next time you pick up a bottle of "vegetable" oil, look at the ingredients. It will usually be safflower or a blend of different vegetable oils.
Less is not more. More is more and more is fabulous.
