Vegetarian and depressed

Not sure that too much should be made of this (the number of vegetarians involved seems not very high to me), but still:
Vegetarians are at higher risk of suffering depression compared to those who eat meat and consume a conventional balanced diet, according to a new study. 

A Bristol University study of almost 10,000 people from southwestern England discovered that were almost twice as likely to develop depression because of vitamin and mineral deficiencies that can negatively impact their mental health.

The 350 committed vegetarians who participated in the study had a higher average depression score when compared to the meat eaters, according to the study published in the Journal of Affective Disorders.

Without meat, a vegetarian's diet tends to have less vitamin B12 consumption, as well as greater intake of nuts that contain , which have been linked with an increased risk of problems.

In addition, roughly 50 percent of vegans and 7 percent of vegetarians have a vitamin B12 deficiency. Vitamin B12 can be found in red meat and plays an important role in affecting an individual's mood
What's this about nuts being linked with nuttiness, too?  That was something I don't think I have heard before, but yes, there are many links - like this one - about the Omega 3 and Omega 6 ratios and mental health.

The study, however, did not rule out the possibility that the vegetarians' decisions to adopt their diet could have been a symptom of depression from the get-go.

•Nutritional deficiencies may account for these findings, but reverse causation and residual confounding cannot be ruled out.

Vegetarians [n = 350 (3.6% of sample)], had higher depression scores on average than non-vegetarians (mean difference 0.96 points [95%CI + 0.53, + 1.40]) and a greater risk for EPDS scores above 10 (adjusted OR = 1.67 [95% CI: 1.14,2.44]) than non-vegetarians after adjustment for potential confounding factors.

Retrospective studies are not studies to draw conclusions from.

.96 points is instructive? Get outta here.
