What is the best healthiest oil to cook with?

and also to not cook (salad dressings etc).

I am confused with all my research. I use olive oil right now.

who puts the thumbs down? if you do it say why!
because it's not helping!

can someone tell me why I should not use olice oil to fry with?

Mono-saturated oils are the healthiest. Peanut and olive are the most popular mono-saturated oils. Olive oil imparts flavor and is used when you want its flavor to accent the other ingredients. Peanut oil has a bland flavor and is used when you don't want the oil to lend flavor to the other ingredients. Olive oil's smoke point is to low for frying. Peanut oil has a high smoke point and is good for frying. Enola Brand oil is a blend of several oils and has Omega 3, 6 & 9 fatty acids added and is considered a healthy oil.

Canola (rape seed outside the USA, notice there is no "G" in rape), sunflower, safflower and corn oil are poly-unsaturated oils and are considered the next best.

To tell if an oil is poly or mono saturated, place it in the frige for a couple of hours. If it clouds and becomes viscous it is mono-saturated. If not it is poly-unsaturated. Oils that are solid at room temperature are saturated fats, e.g. butter, margarine,lard.

Note: Unfortunately a thumb up/down does not offer the option of commenting on why the choice. I noticed that there are several thumbs down for answers that are good answers. Mine is also a good answer. I am a certified Family Food Educator and a ceritified Family Nutrition volunteer with the USA Extension Service. I assume the thumb down that has been placed on the good answers that have been submitted are done as a prank, or by someone is who is misinformed about oils used for food.
