> The evidence for the harms of canola oil is still in its early days, but continues to grow. Research has linked it to: Memory impairment [1], Alzheimer’s risk [1], Cardiovascular disease [2], [5], [6], [8], Diabetes [2], Increased all-cause mortality [2], [6], [7], Metabolic syndrome [3], Decreased brain function [4], and Oxidative stress [5], [7].

Most of these references talk about how there is no clear benefit of vegetable oils over animal oils or how "chronic canola oil consumption" results in obesity in transgenic mice. That is not really the same thing as "growing evidence for the harms of canola oil".

For completeness, I checked them all and the score is:

* Rat

* Rat

* actually about cooking _in_ canola oil

* about switching _any_ vegetable oil to _less_ olive oil

* Rat

* actually about a different oil with quite different content of the active acid being trialled

* Rat

* Rat

(Oh, and the article is written by a SEO marketer)

https://news.ycombinator.com/item?id=24090817 points out that rats, rather uniquely, cannot process erucic acid (part of canola oil) and the rat studies likely do not apply to most other mammals (including humans).

At this point, we should all just flag this article til it's gone. It's FUD

I'm curious of your actual hunch, are you actually skeptical that canola (and other industrial seed oils) are not harmful?), or just pointing something out about the evidence?

[cinntaile]

I read it as twanvl pointing out that there is a lack of evidence to support the article's claims.

I would be interested to know if these studies refer to low quality vegetable oils using a chemical process to extract oil. For example, in the UK, supermarkets sell cold-pressed rapeseed oil (canola oil in the US). The cold-press process is sold as making rapeseed oil as relatively healthy cooking oil.

Does cold-pressing rapeseed/canola seed turn it into a relatively healthy cooking oil (vs the expeller-pressed or chemical extraction process)?

[lambdaba]

The problem is the fats in those oils are very susceptible to oxidation and have low smoke points, they are never safe as cooking oils for this reason.

For cooking the best options outside of animal fats are olive oil and coconut oil, but of course olive oil is most versatile and better tasting imo.

> obesity in transgenic mice.

I definitely read this as "obesity in transgender mice" the first couple times and was seriously wondering if that was actually a thing.
