While it does contain omega-3 fatty acids, the ratio of omega-6 to omega-3 is dangerously high. Extracted from the seeds of the rapeseed plant, this oil undergoes significant industrial processing that fundamentally alters its original composition.
Why Canola Oil Oxidation Stability Is a Major Health Concern
To isolate the oil, manufacturers subject the seeds to high temperatures and pressures, often using the solvent hexane to strip away the fat. The polyunsaturated fats are vulnerable to oxidation when exposed to heat, light, or air, turning the oil rancid before it even reaches the consumer.
Understanding the Extraction Process The journey of canola from seed to bottle involves methods that nutrition experts increasingly view with concern. These foreign substances place a burden on the liver, which must process and eliminate them, potentially diverting resources from other critical detoxification processes.
Canola Oil Oxidation: Why Heat and Air Make It Rancid
Cooking with canola oil, especially at high temperatures common in frying, creates free radicals that damage cells and DNA. The inflammation triggered by the omega-6 overload damages the lining of blood vessels, setting the stage for hypertension and atherosclerosis.
