Have you ever tried to be vegetarian but found it too difficult to stop eating meat? Your genes could be partly to blame, a new study suggests. 


The research, published Wednesday in the journal PLOS ONE, identified a set of genes associated with people who adhered to a vegetarian diet for at least a year. 


Nabeel Yaseen, the study’s lead author and a professor emeritus of pathology at Northwestern University, said the findings may indicate that sticking with vegetarianism isn’t solely a matter of willpower. 


“The take-home message is that, based on your genetics, a vegetarian diet may or may not be appropriate for you,” Yaseen said. “You don’t need to blame yourself if this is something you can’t really stick with.”
