Canola oil friend or foe of your heart?
Canola oil which is highly recommended by many physicians and is thought extremely healthy for your heart has now left unanswered questions for many people.
Canola oil which was first manufactured by a Canadian industry by rapeseeds which were earlier used for industrial purpose is genetically engineered to eliminate the unwanted and bad tasting ingredients from the rape seed like Erucic acid, that was seen to cause heart damage in some rat studies and Glucosinolates, that were thought to have bitter taste, to make this rapeseed oil edible.
Canola oil is simple oil that stands for “can” for Canada and “ola” for oil, but actually it was seen to pass through many complicated and harmful procedures during manufacturing in order to extract the oil from the seeds.
During canola oil manufacturing, it is passed through a very dangerous solvent called hexane that is very toxic for health. Sometimes traces of hexane are seen in the oil which is left after the oil is extracted from the seed. The seed contains about 45%of the oil; the remaining is used as fodder for animals.
The canola seeds are genetically modified most of the time, in fact there are no canola seeds in real, rapeseed are modified to produce these canola oil seeds. When this highly unnatural manufacturing process is taking place, much of the oil gets damaged but it’s not possible to identify if the oil has damaged since the canola oil’s smell is also masked.
Excessive heating, exposure to solvent hexane and deodorization during the process of production results in the production of Trans fats in the oil, which is the major cause of heart problems and is very unhealthy.
Canola oil is claimed to contain lower saturated fats and higher unsaturated fats. it has a balanced ratio of omega 3 and omega 6 fats but recent studies suggest that for long time the saturated fats that are thought bad for you have nothing to do with your heart, so that leaves all the goodness of low in saturated fat pointless for canola oil.
Now it is true that canola oil has a balanced ratio of omega 3 and omega 6 fats but guess what? We only need these in a limited amount and consuming a lot of canola oil will raise our polyunsaturated fats to undesirable levels that can incorporate into our cell membranes and are prone to oxidation that can initiate free radical chain reactions leading to the damage of important molecules and DNA.
Canola oil is also a source of lowering cholesterol levels, which is true and many trials have proved it too, but the trials that were conducted were very short for determining the affects of canola oil on heart.
The longest study was about 4weeks long. These studies proved canola oil to lower cholesterol levels up to 25%but raised cholesterol levels is a risk factor not a possible cause of heart disease.
Some other studies suggest that vegetable oils can lower cholesterol levels in short term but can increase chances of heart problems in long term.
Canola oil is low in nutrients, high in omega 3 and omega 6 fats and Tran’s fats too, which doesn’t make it very healthy. Over all, canola oil is not as bad as other many vegetable oils like soybean oil etc but if you can get organic/cold press canola oil that would be a better choice than the conventional canola oil.
It would be much better to go for olive oil or coconut oil other then keep your head wondering what is true about canola oil and what’s not?
