Is rapeseed oil bad for you? Rapeseed oil and canola oil
Rapeseed oil for food use is often debated: they date back to the yearsSeventythe first studies that highlighted the potential health risks associated with the consumption of rapeseed oil. We talk aboutcardiac lesions and myocardial lipidosis. The offending substance is contained inrapeseed oilit is erucic acid which accounts for 60% of the weight of this vegetable oil.
To allow the use ofrapeseed oil, the food industry has given birth to severalmutationsof Brassica napus (rapeseed). Thanks to these mutations it would be possible to produce a rapeseed oil rich in polyunsaturated fatty acids and almost completely free of erucic acid. This rapeseed oil derives from genetically mutated crops but it would seem to have beneficial properties for health.
The first varieties of brassica (canola) that are mutated and capable of producing low erucic acid canola oil were developed in Canada. In the beginning, the mutated rapeseed varieties were able to produce an oil with erucic acid content of less than 5%. Subsequently, varieties were developed containing always lower percentages of erucic acid up to the variety00 that set the standardCanola.
L'canola oil it is nothing more than canola oil containing less than 2% erucic acid. Therefore, edible rapeseed oil is bad butcanola oil produced from mutated varieties of the same plant as rapeseed may not be as harmful.
The wordCANOLAis nothing other than the contraction of the word CANadian Oil Low Acid, literally translatedCanadian low-acid oil.
The oil ofcanolait is extremely cheap and therefore widespread in the food industry. It is used by many franchising chains for frying food.
If canola oil does not have erucic acid, then why is it bad? Studies on this are controversial. What makes a lot of discussion is the production process of this oil: it is a refined vegetable oil, the production involves an extraction process at high temperatures with the use of solvents and controlled pressure. Once extracted, the oil is bleached and deodorized.
Rapeseed oil, properties
Despite this, in many countries rapeseed oil (or better, canola) is valued for its nutritional properties: it contains monosaturated fats (oleic, gadoleic), Omega 3 and Omega 6 polyunsaturated fatty acids and saturated fatty acids (steric palmitic) . Thanks to hispropertynutritional, the FDA, in 2006, declared this vegetable oil capable of reducing the risk of cardiovascular disease. The FDA (Food and Drug Administration)held this declaration because thecanola oilit contains Omega3 and Omega6 polyunsaturated fatty acids, however it made no statement about the extraction process.
