Vegan diet linked to delusions in student's death, inquest finds
An inquest in Cambridgeshire concluded that Georgina Owen, a Swansea University geography student, died after developing delusions likely caused by a vitamin B12 deficiency tied to her three-year vegan diet; she had stopped taking B12 supplements for several months, and psychiatrists noted cognitive impairment and delusional beliefs associated with the deficiency, with the coroner stating the death occurred on the balance of probabilities due to these factors.
