I’m certainly in favour of exchanging saturated fat for canola. I believe it was Finland where they made a big push to use canola rather than butter and the health outcomes seemed significant. There were confounding factors, but nonetheless, it was clear that a reduction in saturated fats yielded better life expectancy and lower rates of heart disease. The results were actually in line with what prior research indicated. Finland went from a lowest life expectancy in the world to one of the highest over decades, likely in part because of that transition away from dairy fats.
In that sense I think canola is amazing. I personally avoid both (of course it’s impossible to do so 100% of the time), but I fully support people choosing relatively healthier options.
