What's wrong with canola oil? The fatty acid profile seems pretty healthy to me
- samatman 4y agoIt's important to remember that if this were the 80s, a well-informed consumer would say the same thing about margarine vs. butter. Turns out we were tragically wrong about that, causing tens, perhaps hundreds, of millions to suffer in old age and die prematurely. So if I saw some mild evidence, like most nutrition scientists retiring, that the industry has reformed, that would be one thing. As it is? I think they're lying, from Doing My Own Research™, but your mileage may vary. The important part is that you'd be a fool to trust the industry consensus with your own health.
- feet 4y agoOkay but I specifically asked what is wrong with it, can you cite any sources?
- wil421 4y agoThe only sources they will site are a few doctors with popular books. I’ve read a few of them and they can help you lose some weight. After reading the books based on some internet persons suggestion I realized there’s controversy. Some say it’s junk science pushed by snake oil doctors others says it’s the next scientific revolution. One fact remains, heart disease has gone way down and obesity has gone way up.
- hombre_fatal 4y agoThe whole seed oils thing just seems like a twitter fad/meme. Can anyone share some promising literature? When I search for it, I just see studies about PUFA (polyunsaturated fats) benefits where they seem to always use canola oil (like swapping saturated fats for canola oil) to show benefits. Yet overnight it seems like popular twitter accounts and podcasters have echoed seed oils = bad.
- kritiko 4y agoHasn't life expectancy gone up and cardiovascular events gone down since the 80s?
- dilap 4y agoJust looking at macro fat breakdowns (per cronometer.com) it's definitely one of the better vegetable oils, but still not awesome -- 28% PUFA, 2/1 n6/n3. Which isn't terrible, but like 2.5x the PUFA content of olive oil, and way more than a cooking fat like tallow or butter. (I'm assuming in the above your goal is to keep PUFA low and n6/n3 balanced.) There's also some animal studies w/ canola oil specifically that showed adverse effects, though I don't have them at hand. Just looking at the characterization of fatty acids by unsaturatedness is omitting details which can matter -- the particular makeup of the fats (chain length -- a fatty acid w/ the same unsaturatedness can have varying effects on metabolism at different chain lengths; cis vs trans) as well as all the other chemicals that are in the oil, whether beneficial or harmful. As one example, canola oil used to contain high levels of erucic acid, which is a 9-chain monounsaturated fat generally considered toxic. Over time the levels have gotten lower.

- landemva 4y ago> vegetable oils Canola (Canadian Oil) or rape seed was used as an industrial lubricant oil. The first human lifecycle testing is now showing results. I avoid consuming it. https://www.sciencedirect.com/topics/neuroscience/rapeseed https://www.sciencedirect.com/topics/neuroscience/rapeseed
