Who knows? It might. Truth is almost impossible to find, on any topic. Particularly heavily politicized ones.
they are not natural, and we were never meant to eat it in these quantities we do today and definitely not overly processed this way https://www.healthline.com/nutrition/are-vegetable-and-seed-oils-bad "The problem with polyunsaturated fats is that all these double bonds make them susceptible to oxidation. The fatty acids react with oxygen in the atmosphere and start deteriorating." especially if they have trans-fats "However, non-hydrogenated vegetable oils may also contain some trans fats. One source looked at vegetable oils in the United States and discovered that their trans-fat contents varied between 0.56% and 4.2% (9Trusted Source)."
Argh, long videos. I dare say the 1st one is about canola and sunflower oils etc. So the seeds in the actual fruit are not healthy? I remember a time not that long ago, you could buy grapes that had seeds in them, nowadays it is rare as hen's teeth. I detect you're demonising grapeseed oils with that of cooking oils. https://en.wikipedia.org/wiki/Cooking_oil 7 Health Benefits of Grape Seeds, its Side Effects & Safety Precautions
there could be, sure the dose makes the poison, just like being out in the sun is good, excessive sun exposure is bad
These are possibly the rap sheet of oils you're thinking about, why vegetable oils are bad for you. 5 Reasons Vegetable Oil is Worse Than Sugar FYI, I include coconut oil, cod liver oil and olive oil in my diet.
The best oil is refined petroleum oil, also called gasoline. One should swallow lit matches immediately after consuming it for the most healthy effect.
And this is why I don't put anybody on ignore. Even people like FreshAir might once in a while say something that I agree with. I just about fell off my chair though...
I would (and do) personally use animal fat and/or butter over any sort of oil. Maybe that's just me though.
The vegetable oils that people tend to use are definitely bad. Supposedly those oils that you mention are better than many others, but I just avoid those oils too. I'm big on using animal fat and butter instead.
Lard is actually better that most oils. Lard was the go-to shortening until science learned to hydrogenate liquid oils into a “lard like” consistency, “Big Shortening” advertising campaign proceeded to buried them. (I learned that at the National Lard Conference in Manteca, Ca.) https://www.allrecipes.com/article/difference-between-lard-shortening/
Olive oil, coconut oil. Butter, and lots of it. Tried grape seed oil when I was on one of my 'gourmet' kicks, meh, not worth the extra cost. As to preventing COVID? First time I've heard that.
I forgot the technical and scientific terminology, but vegetable 'cooking' oils are the ones to look out for. Because of the way they're processed, some do not handle heat well and can create carcinogenic properties. "when refined at temperatures above 392°F. This echoes the concerns that Grootveld and his team expressed about heating sunflower and corn oils—a process they found produces compounds that may cause cancer and other diseases." https://www.eatthis.com/vegetable-oil-dangers/
What compounds are these? And what part of human digestion involves the equivalent of heating something to 392 degrees? I love how the latest bugaboo of the food alarmists are the horrible dangers of "processed" foods, by which they generally mean cooked, though even chopping or grinding seem sufficient to make our sustenance poisonous nowadays. Apparently the only safe way to eat is to slaughter the animal in the field yourself, and even then you have to be careful it consumed no antibiotics.
