I’ll confess that I’ve only read the abstract, but was totally confused by this apparent contradiction…

> We found strong correlations between greater consumption of fat and protein to lower anxiety and depression

vs

> We have shown that changing diet affects mood and happiness, that greater fat and carbohydrate intake is directly associated with anxiety and depression

The first says fat reduces anxiety and depression. The second seems to imply it reduces it- unless “directly associated” actually means “negatively correlated”??

Also, are they saying that increased fiber reduces gut biome diversity?
