Consider how each of these are made:
Butter: The cream is separated from milk and churned until it becomes semi-solid.
Canola oil: Over 90% of canola crops are genetically engineered.
Canola oil goes through an industrial chemical extraction- leaving it highly contaminated - consisting of:
1. Roller mill-> screw press to extract oil
2. Second oil extraction with hexane (Studies have found hexane and petroleum based solvents residue in these seed oils (PMID: 11064941, 34745265), which have been associated with cancer in cooking fumes (PMID: 22968348, 10361022)).
Seed oil cooking fumes emit 5.9 times more benzo[a]pyrene than cigarette smoke. (PMID: 14643283)
3. Sodium Hydroxide wash, followed by cooling to remove waxes. Are you sure you want to eat this stuff? But wait, weโre not doneโฆ
4. Bleaching, followed by steam deodorization to temps of 260/500F! If you think heating a fragile, polyunsaturated oil to these temps is benign, think again. (PMID: 30557357,16296405). Research at the University of Florida in Gainesville found trans levels as high as 4.6 percent in commercial liquid oil. (OโKeefe et al. 1994)
So, what are we left with?
A contaminated (hexane/benzene (PMID: 11064941, 34745265), heavy metals (doi.org), PFAs (PMID: 37726506), highly oxidized oil that is harmful for humans and leads to de novo lipogenesis (DNL)(PMID: 19802339, 27020609), a process that has been linked with obesity and eventually diabetes.
Seed oils like canola are also high in linoleic acid, an Omega-6 polyunsaturated fatty acid known to increase oxidized LDL and Lp(a), clearly raising the risk of cardiovascular disease. (PMID: 8432867, 28503188)
No, we donโt have perfect randomized, controlled trials with seed oils vs saturated fat in humans, but the BEST trials we have (Minnesota Coronary, Rose Corn Oil, Sydney Diet Heart), all point to increased cardiovascular risk with seed oilsโฆ (see my tweet thread on human RCTs for more details).
