It's in our food supply. In fact, it's ubiquitous in our food supply from salad dressings to crackers to gluten-free potato chips and

pretzels, cereals and beyond. Canola oil is everywhere. Little did you know

that this was repurposed motor oil. Yes, let me tell you the story of canola oil and we'll talk

specifically about how diets high in canola oil are problematic for increasing your

risk of cardiovascular disease because it turns out that canola oil is enriched in linoleic

acid that can increase your LDL cholesterol to become more oxidized or modified increasing

your risk for cardiovascular disease in atherosclerosis.

But first, let's talk about the story of canola oil,

because these details matter, my friends,

because there's no human or animal

that would ever be able to physiologically consume

large amounts of canola oil because it turns out that

canola oil has high amounts of a toxic fatty acid, that's 22 carbons long known as

uristic acid.

And it wasn't until scientists in Canada specifically at

University of Manitoba in the 1980s discovered techniques distillation techniques

and processing techniques to remove this cardiotoxic uristic acid out of the oil to make it safe for human

consumption. So here's the history and backstory on canola oil. It's derived from the

rapeseed and it is classified in the Brasca family along with

turnips, cabbage, broccoli, and mustard seeds. Since the Industrial Revolution

rape seed oil has been an important component of lubricants for ships and steam
