If you are strongly looking to avoid GMO issues, try to buy organic and non-GMO oil from the market which is truly a bit high in pricing. You can even go for cold-pressed canola oil which is the best for culinary purposes.

The level of erucic acid is thought to be in low levels in canola oil which is an omega-9 fatty acid. This is said to pave the root for cardiac issues. 


Canola oil is prepared synthetically from canola plant seeds and is widely used in cooking. Some studies have linked canola oil usage with improved heart and health conditions while some early studies indicate that the oil can cause inflammatory responses and can negatively impact heart health. Yet these are very early claims and require further scientific studies. Till then, remember to use oils in limited amounts as they are a rich source of fats.
