As someone who teaches wellness and a big foodie for a while. I'll try to clarify.
Someone mentioned that coconut oil is bad. Not true. It's one of the healthiest oils around. Best to use raw and more like butter or for baking.
Canola is a great choice for cooking. There is a high heat Canola oil that is designed just for this. Olive oil is a great choice. Regular virgin is best for cooking. Extra virgin to be used for salads and such.
Peanut is the least desirable.
Hope this helps,
