Oil, Oil, Oil!
There's much to say about oil in food. FIrst, you have unrefined and refined; refined has undergone chemical processing and some discourage its use for health reasons. You also have animal oil and plant oil; and some discourage one, others the other; both for health reasons. Here is a further breakdown:

- Olive Oil- is not recommended for deep frying although refined olive oil or light olive oil may be used if you prefer. Smoke point is low to medium depending on kind. Extra Virgin Olive Oil is the highest of quality, it is unrefined, best for salad dressings, not good for sauteing since you will just destroy the nutritional content. Use Virgin Olive Oil for salad dressings and light vegetable sautes. Refined Olive Oil is cheaper and in terms of nutritional content, more inferior. it is however suitable for sauteing and frying. Pure Olive Oil is the least kind as to nutritional benefit and commonly recommended for skin and hair health purposes rather than cooking. It is a blend of virgin and refined olive oil. Pomace Olive Oil is different from Regular Olive Oil as for one, it is hot-pressed (heated above 80 degrees F, which destroys nutrients) and, number 2, it is chemically processed from remaining olive oil.
