Sunflower or Canola Oil?

I've been using Canola oil for a long time now, more than 12 years. I read and heard in the news that Canola oil is very good for your health, especially your heart health. Now, I read in a health/exercise magazine that sunflower oil is very good too. It has conjugated linoleic acid, a naturally and healthy fatty acid that is essential to the basic funtions of the body. Moreso, it has beed shown to help burn fat and build lean muscles. It sounds good, doesn't it? I have to research more about it though. I want to be sure that it is the best for me and my family. Have you tried sunflower oil?
