Americans eat 12.51 million metric tons of it a year, so it is clearly not exactly poisonous. And "inflammation" is very vague... most people would be better off just increasing their dietary fiber intake and not worry about swapping one fat for another. It doesn't require thousands of people with no education in the area creating social media content about it.
This is the first time I've heard anyone argue that a food product must be good for you because Americans are consuming a large amount of it. How on earth could you come to that conclusion given how unhealthy our population is?
Americans are not the healthiest population on average so if anything, it proves the reverse point that you are trying to make...
Also, fiber advice is complete nonsense. There are now plenty of studies showing that fiber causes more problems, especially for people who get easily constipated.
The fiber bullshit comes precisely from bad science, that is directed by wants and political opinions, especially those of women in that case.
Fiber advice has come around because for some reason, it was thought that defecating more often is better and women like to "work" on their transit because of them wanting to look as fin as possible at all times.
So, they make you eat very low energy (and nutriments) food to make you shit more often, just because.
