The last paragraph of the Discussion section makes it clear that fat on its own isn't to blame:
> This pilot study examined correlations between diet composition, mental health, mood and happiness, and the gut microbiome to find that fat and protein reduce anxiety and depression while carbohydrates have the opposite effect.
As I'm understanding it, this is funded by a public health institution in the USA. Health institutions all around the world have been especially sensible to the idea that cholesterol and saturated fat are absolutely bad, even if we know now that it's probably not the case. I guess they kept it politically correct in the Abstract to save face, even though their study says the opposite.
Now it should be noted, as others' have, that it's just a n=22 study.
