does canola oil come from the stem
Answers from Katherine Zeratsky, R.D., L.D. Health concerns about canola oil are unfounded. Canola oil, which is extracted from the seeds of the canola plant, is generally recognized as safe by the Food and Drug Administration. Misinformation about canola oil may stem from the fact that the canola plant was developed through crossbreeding with the rapeseed plant. Rapeseed oil contains very high levels of erucic acid, a compound that in large amounts can be toxic to humans. Canola oil, however, contains very low levels of erucic acid.
