I downvoted because by the HN guidelines comments should try to be curious and interesting and because “Please don't post shallow dismissals”. The abstract mentions that diet affects gut microbiome and that gut microbiome has a “shaping effect” on psychiatric disorders: > “A growing body of literature shows that the gut microbiome plays a shaping role in a variety of psychiatric disorders, including major depressive disorder (MDD). In this review, the interplay between the microbiome and MDD is discussed in three facets. First, we discuss factors that affect the onset/development of MDD that also greatly impinge on the composition of the gut microbiota—especially diet and stressful life events.” That is, the comment is low effort, and dismissive, and unsubstantiated speculation. Are we supposed to conclude that “depressed people eat junk food” is all there is to it? Citation requested. Are they just saying “depressed people eat junk food”? Boring. Are they saying “maybe depressed people eat junk food”? Is there a reason to have “maybe” there? Might they not?
