TheIn 2014 researchers from the Medical University of Graz published a study, The Association between Eating Behavior and Various Health Parameters which concluded in the abstract:
... a vegetarian diet is associated with poorer health (higher incidences of cancer, allergies, and mental health disorders), a higher need for health care, and poorer quality of life.
The study was subsequently reported on by the media with titles like reported here"Vegetarians are 'less healthy and have a lower quality of life than meat-eaters", "suggests non-meat eaters are more at risk of physical and mental illnesses" (independent.co.uk).
The article Are Vegetarians Less Healthy than Meat-Eaters? (from a vegan sitetheveganrd.com) is pointing out some issues with the study, but I wanted to know if other scientists have also pointed out some issues with the study, or if this is the accepted wisdom today.
Any credible links discussing the study (in lay terms) would also be welcome.
