Because they’re running counter to big agribusiness and other evil government and corporate types, it piques my interest, but most of these people seem dangerously adjacent to “carnivore diet” weirdos. I’m vegan I’m not gonna use tallow dude. Coconut oil would be fine thanks.
Anyone smarter than me know the real score?
This doctor does a breakdown in this video of a paper that came out last year and likely reignited this whole thing again. He provides references to other papers in his description and includes a breakdown of some basics on the impacts of excess saturated fat consumption.
TL;DR saturated fats are okay to eat but shouldn't exceed 10% of your caloric intake, the counter crusade against against unsaturated fats is likely based on poorly formulated studies (and imo may also be a crusade supported by the dairy industry to beat out butter alternatives).
Edit: what I'm getting from this video, and what is likely the source of the "vegetable oils bad" thing is that vegetable oils tend to be good sources of polyunsaturated fats like Omega 3 and 6 (which are good fats), but vegetable oil tends to be in a lot of junk food. People will then substitute their saturated fat intake with junk food, which coincidentally means they consume vegetable oils (polyunsaturated fat) together with trans fats and processed carbs.
Then some papers have not properly distinguished consumption of polyunsaturated fats straight from the source i.e. olive oil versus consumption from a mixed source i.e. junk food, and, therefore, end up incorrectly concluding that the replacement of saturated fats with unsaturated fats (polyunsaturated fats) is unhealthy on its face. When if they made the distinction, they would likely reach the same conclusion as other studies: replacing saturated fats with unsaturated fats (particularly polyunsaturated fats like Omega 3 and 6) results in better cardiovascular health.
