If you’ve been following my fitness newsletters for any length of time, you should have noticed, I NEVER include canola oil in ANY of my recipes …nor do I include it on any of my lists of healthy foods.
Many have asked me why that is. All they hear in the mainstream media is that canola oil is “heart healthy” …and a good source of monounsaturated fats, similar to olive oil. That couldn’t be further from the truth.
First of all, you need to realize that much of what you read and hear about in the media has been influenced by heavy-handed marketing tactics by major food companies. Canola oil is cheap for them to produce so they want to dupe you into believing this is “healthy oil”. This way people, restaurants, etc., will buy it up as their oil of choice for regular use.
The Dirty Truth About Canola Oil
Yes, it is true that canola oil is high in monounsaturates, but let me explain why canola oil is anything BUT “healthy”.
Canola oil is made from something called rapeseed. Rapeseed actually has been altered over the years to reduce the percentage of a problematic component of rapeseed, which is erucic acid.
Important note on canola oil “urban legends”: There is a problem with most websites that DEFEND canola oil, saying that internet “urban legends” on the dangers of canola oil are unfounded.
The problem is that these websites that defend canola oil ONLY talk about the issue of erucic acid. The issue of erucic acid IS an urban legend, because erucic acid has evolved to very low levels over the years, so it is a non-issue.
The websites that defend canola oil are “barkin’ up the wrong tree,” because they do not address the issue of the processing of canola oil …and oxidation of the polyunsaturated component of canola oil, which is what makes it unhealthy for human consumption.
THAT’S the real issue that they either don’t understand (because they are not nutritional experts) or they are simply ignoring this issue.
Let Us Look at the REAL Issues With Canola Oil:
Canola oil typically ranges between 55-65% monounsaturated fat and between 28-35% polyunsaturated fat, with just a small amount of saturated fat.
While we’ve been led to believe that high monounsaturated fat oils are GOOD for us (which they are in the case of virgin olive oil …or from unprocessed nuts or seeds), the fact is that canola oil has more DISadvantages than it has advantages.
As you may have red in other newsletters of mine …or in my Truth about Abs book… one of the biggest problems with highly processed and refined vegetable oils (such as corn oil, soybean oil, and yes, even canola oil!) is that the polyunsaturated component of the oil is highly unstable under heat, light, and pressure …and this heavily oxidizes the polyunsaturates which increases free radicals in your body.
The end result of all of this refining and processing are oils that are highly inflammatory in your body when you consume them. They potentially contribute to heart disease, weight gain, and other degenerative diseases.
The reason that extra virgin olive oil is good for you is that it is cold pressed without the use of heat and solvents to aid extraction.
Canola oil, on the other hand, is typically extracted and refined using high heat, pressure, and petroleum solvents such as hexane.
Most canola oil undergoes a process of caustic refining, degumming, bleaching, and deoderization… all using high heat and questionable chemicals.
Does Canola Even Have Trans Fats?
Even worse, all of this high heat, high pressure processing with solvents actually forces some of the omega-3 content of canola oil to be transformed into trans fats.
According to Dr. Mary Enig, PhD, and Nutritional Biochemist, “Although the Canadian government lists the trans fat content of canola at a minimal 0.2 percent, research at the University of Florida at Gainesville, found trans fat levels as high as 4.6 percent in commercial liquid canola oil”.
…and this is the crap they’re marketing to you and I as a “health oil”?
As you can see from the details above on how canola oil is processed, are YOU convinced that it’s any healthier for you than other junk oils like soybean oil or corn oil.
The bottom line is this; it’s an inflammatory oil in your body and should be avoided whenever possible.
The only canola oil that MIGHT be reasonable is IF you see proof that it is “cold pressed” …and organic. I rather doubt you’ll find any as most canola oil is NOT cold pressed or organic. So, why not choose oils that you know are healthier.
Your best options are the following oils:
So don’t be fooled by food labels claiming that they contain “healthy canola oil”… as you have learned here, this couldn’t be further from the truth! Choose some of the healthier options from those listed above and your body will thank you.
