Unfortunately the full text of this study isn't on SciHub, but it's a very good study. They assigned veterans to one of two mess halls randomly, and in the experimental group they fed them food with the fat content replaced with corn oil (which is 46:1 omega 6 to 3 ratio). They also did a pre-study to make sure the fat-replaced food was palatable and hard to distinguish from unaltered food higher in saturated fat. The experimental group had significantly lower CVD outcomes and lower all cause mortality.
Don't worry about linoleic acid, it's either benign or healthy.
Only when describing the complete daily intake for some category of nutrients it is possible to say whether the quantities that are used are healthy or unhealthy.
In most human studies it is pretty much impossible to feed all the participants with exactly the same food and to vary independently various ingredients over long times in such a way as to obtain a reasonably certain conclusion.
For instance, in most days around 90% of my daily intake of fatty substances comes from a mixture of 4 oils: 50 mL of extra-virgin olive oil + 20 mL of cold-pressed sunflower oil (required to provide enough linoleic acid and enough vitamin E) + 5 mL Schizochytrium oil (provides enough DHA & EPA omega-3, can be substituted by 10 mL of fish oil, e.g. cod liver oil) + 1 drop of oil containing D3 & K2 vitamins.
According to the current knowledge, this mixture of oils is healthy.
Nevertheless, it is not possible to say that any of its components, e.g. olive oil or sunflower oil, are healthy in isolation, unless the total daily consumption and the total daily consumption of any other fatty substances are specified.
Where do you think our ancestors got their water? Certainly not highly purified and disinfected water straight from a water treatment plant and piped to their house. Should we go back to drinking from lakes and rivers?
You probably meant to call my argument an appeal to nature. You seem to really know your stuff.
>Where do you think our ancestors got their water?
Lakes and rivers.
>Should we go back to drinking from lakes and rivers?
Preferably yes. I came back from a camping trip yesterday where I strictly drank from lakes and rivers, and it's very refreshing compared to city water.
I suppose this wasn't the gotcha you had planned in your head.
You are free to do whatever you want, but ignoring well understood issues of the world over a single personal experience is the though process of a small child.

The problem is that most of them (minus olive oil) are high in saturated fats, which are also bad. Out of the frying pan, into the fire.
people will often look at old photos and wax poetic about how youthful and thin everyone was. why? they were eating saturated fats and not seed oils.

Can you present some examples of this "growing snowball of evidence"?
>A lot of the "studies" we have right now which paint saturated fats in a bad light are not true to the mission of science.
What makes you think that? Is it just based on funding/affiliations alone? Or do you have specific methodological concerns about the studies that they use, that your studies don't have?
If you read enough you sort of absorb it, someone else can cite some good reviews I'm sure. I will just drop a few names here if you want to investigate - Rhonda Patrick, Eric Berg, Peter Attia...
Edit: here is a published review, just the tip of the iceberg https://www.jacc.org/doi/10.1016/j.jacc.2020.05.077
I skimmed the review and the conclusion seems to be "saturated fat from certain sources probably isn't bad for you"[1]. If we take that at face value, and go back to the original question of whether to replace vegetable oil with oils high in saturated fats (eg. palm oil or ghee), I think the answer is still "no". The article talks specifically talks about foods like whole fat dairy (not pure butter), unprocessed red meat (not lard) and dark chocolate (not palm oil).

Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease https://pubmed.ncbi.nlm.nih.gov/20071648/
> Conclusions: A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD. More data are needed to elucidate whether CVD risks are likely to be influenced by the specific nutrients used to replace saturated fat.

> Conclusion: Dietary recommendations were introduced for 220 million US and 56 million UK citizens by 1983, in the absence of supporting evidence from RCTs.
