Another concern is the report that canola oil might contain trans-fats that have been linked with significant health problems. In fact, canola oil does contain very low levels of trans-fat, as do all oils that have been deodorized.
Deodorization is the final step in refining ALL vegetable oils. This process produces the bland taste that consumers want. Other vegetable oils, and even nut oils, have been found to contain levels of trans-fatty acids that are comparable to the levels in beef fat.
