Going meatless may not be just a matter of willpower, according to a new study.
The study published Wednesday in PLOS One found that there are four genes associated with how well someone is able to adhere to a vegetarian lifestyle.
At this time we can say is that genetics plays a significant role in vegetarianism and that some people may be genetically better suited for a vegetarian diet than others, said lead study author Dr. Nabeel Yaseen, professor emeritus of pathology at Northwestern University’s Feinberg School of Medicine.
In addition to religious and cultural practices, health, moral and environmental reasons all rank among the factors that motivate people to reduce or eliminate their meat consumption — but they aren’t always so successful, Yaseen said in an email.
