> Canola and other seed oils are made using toxic solvents which are not full removed from the final product.
This is simply untrue. Independent bodies all over the world regularly test commercially available oils for toxic solvents. While the solvent Hexane is indeed commonly used in the extraction of refined vegetable oils, it is later removed in the refining process.
For example Stiftung Warentest, an independent consumer advocacy organization tested 23 rapeseed oils available in German supermarkets and they all came out clean [1].
A few years earlier, they tested 25 "specialty oils" and found traces of Hexane in only one of them - but still way below the EU threshold of 1 mg/kg. [2]
Here is a study from Japan that tested a bunch of vegetable oils and came to the conclusion that none of the products contained dangerous levels of Hexane. The maximum amount the researchers found was 42.6 µg/kg (again way below the EU threshold) - but in most samples the amount they found was so low they couldn't even get a reading or they didn't find any Hexane at all.
Besides, for cold-pressed oils, no solvents are used at all.
These studies are done to rebuff claims by people whose cohort largely overlaps with those who believe that homeopathic medicine is legit. It's not gonna change squat in their minds.
Sydney heart diet study: Seed oil group had something like 62% higher death rate.
Minnesota coronary experiment: replaced saturated fats with seed oil, cholesterol dropped, but for every 30 mg/dL drop risk of death went up something like 20%.
Several recent meta analyses also indicate no real benefit migrating from saturated fats to seed oils. The only silver lining I have seen is there is some evidence replacing them for people who have had a coronary event already. So, no, I don't think the evidence supports "seed oils do much better" in a general sense.
I don't have time to look into the sydney heart study but I know for the minnesota experiment they, not knowing how bad it was at the time, used margarine with high trans fats as the replacements. Also had a huge 95% drop out rate
Actually on a quick check the sydney study looks to be the exact same
Look at a meta review. There are a ton of these studies and the overwhelming evidence is that saturated fat is associated with CVD and ACM, PUFAs are not.
