Worth going down that rabbit hole a bit. They’re high in PUFAs, which cause inflammation and don’t let cells function properly.

They’re believed to lead to or exacerbate sunburns.

They were industrial lubricants up until the 1840s or 50s.

I rather play it safe but it’s very hard to avoid them. They’re in most processed foods.

From what I understand cold pressed & expeller pressed are better than heat extracted oils.
