This article is suspect to me. Only 3 references, none of which are actually studying depression and diet.

If this was true, wouldn't we see depression in communities with lower cholesterol, Communities like the Seventh Day Adventists, many of which are vegetarian or vegan?

Personal opinion, articles of this quality are to keep the public confused on diet and maintain the status quo. The food industry is a giant money machine. It can't survive if you're eating boring old unprocessed plants for the majority of your diet.

Here's a more reputable meta study on the subject of diet and depression. It's long so skip to the conclusion if you want the unsurprising results.
