Specifically vegetable seed oil, like sunflower oil or canola oil.

The other thing I'm very skeptical of now is milk replacements, like oat milk.

For cooking just use olive oil, coconut oil, or regular butter.

What do you mean?

Please be more specific, my understanding is there is no easy X is harmful in nutrition. Your example vegetable seed oil:

Refined sunflower oil at high temperatures --> bad Cold pressed sunflower oil --> ok (great source of Vitamin E, but too much omega 6 compared to 3) Cold pressed linseed oil --> good

Could you elaborate? You can make oat milk easily at home. Let oat flakes soak in cold water over night, blend, sift, done. Go fancy and add a drop of rapeseed oil (will work as a natural emulsifier) and a pinch of salt.

So the problem with all of those oils is the high concentration of PUFA which is more susceptible to oxidation and thus causes inflammation.

Commercial oat milk like that made by Oatly has rapeseed oil added into it and is then pasteurized. Heating vegetable oils is bad. https://www.sciencedirect.com/science/article/abs/pii/S15371...

Maybe something home made isn't bad.

Pasteurizing happens at like 160F. Vegetable oils oxidize at 350F or above.

There’s a palm oil hysteria in Russia. Social media is full of moms saying that palm oil has been banned in the EU. Yet here I am, enjoying pastry with palm oil in Belgium.
