Vegetarians Are More Likely to Be Depressed, But Not For The Reason You Think

According to recent research, vegetarians experience roughly twice as many
episodes of depression than meat eaters.
The findings, based on survey data from Brazil, fits with past studies that
indicated higher incidence of depression among individuals who avoid meat.
However, the results of this current study demonstrate that this connection
holds true regardless of dietary habits.
It may appear straightforward to look at a link between a diet and specific
health problems and infer that the former is causing the latter via some
type of nutritional deficit.
