Question about seed/ vegetable oils

(icky) #1

Hi, so I’ve cut seed/ vegetable oils out of my diet for ages cos I read about how bad they are, made a mental note of it and never bought any again.

I was telling a friend about it who was really interested in it and he asked why they’re unhealthy and I couldn’t say cos I didn’t bother memorising that bit… :smile:

I realise I could just go and google it but then I’d have to wade through so much blahblahblah trying to work out which are the legit studies and which is the proper science…

So cos I know y’all are so knowledgeable about this, do you mind pointing me in the right direction so I can explain it to my friend properly?

Good place to start is this thread:

Short version is they’re usually all rancid and they have a way off Omega 6 balance which is inflammatory. Problem is if they fact check it, while many don’t disagree on the Omega 6 issue, all the studies showing their safe are doing just that, showing their (safe), ie: won’t hurt you directly, and they won’t. But like a lot of things, it’s the constant papercuts that get you.

People that are used to them will never notice a difference, it’s only those of us that pull them totally out that actually notice the difference after consuming enough of it. Even then, if people don’t have inflammation problems, they may not notice it at all. One of those things where you’re better off teaching them inflammation = bad, and that high Omega 6 =- inflammation, whereas real fats don’t do that. But if they’re the type to still believe saturated fats are bad, you’re back to square 1, since that’s how they got popular in the first place.

I believe Cate Shanahan has a theory about cell membranes. Basically, that torturing plants which would never produce oil from simple pressing with superheating, bleaching, deodorizing and so forth creates a very unnatural lipid. If the cell membrane uses this as a building block instead of a natural fat, it doesn’t function properly anymore. Her original metaphor was building a house with styrofoam balls instead of bricks. It all goes fine until it rains.

It’s an idea that makes sense to me, but I honestly don’t know if this has been researched or proven.
