The majority of studies, and especially the higher quality studies, showed that those who avoided meat consumption had significantly higher rates or risk of depression, anxiety, and/or self-harm behaviors. There was mixed evidence for temporal relations, but study designs and a lack of rigor precluded inferences of causal relations. Our study does not support meat avoidance as a strategy to benefit psychological health.
I think people on the left as whole would be more prone to depression and anxiety too. People who care about the world are generally more concious, more self-aware and critical, which turn into more worrying and at the extreme, anxiety.
Not only that, but also vegan diet is literally making people crazy (or crazy people are more often on vegan diet, dealer’s choice).
