Small-Scale Question Sunday for October 27, 2024

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Yeah I feel like there’s enough evidence to warrant avoiding seed oils from a precautionary principle standpoint.

Since there are no real benefits to seed oils except for their low cost it’s an easy choice to avoid them whenever possible.

I don’t use them in home cooking because saturated fat tastes better. But where is the evidence that polyunsaturated fats are worse for you? Like there’s all sorts of claims about soy, and some of them are likely true, but it seems like disentangling polyunsaturated fats from phytoestrogens is beyond the ken of current knowledge. Where’s the evidence against canola oil(and no, it having once had an unfortunate name is not evidence) and cottonseed oil and the like?

I don't have the studies at my fingertips. I'm confident I could dig some up quickly because there is a large and active anti-PUFA community. But it's definitely not in my wheelhouse so I'd leave that to others who are more qualified.

Nevertheless, I see no benefit to eating foods which were created essentially de novo in the last 50 years and whose use has correlated highly with the rise in obesity. The processes for making safflower oil, for example, are completely foreign to anything granny would have done, and typically involve the use of industrial solvents (Hexane) and machinery.

Flip your question. Where are the studies proving that seed oils are healthy? Got a source for that?

When I have a choice, I'll try to avoid seed oils until they can be proved healthy. There is no downside if I'm wrong. People who eat lots of seed oils can't say the same.
