Researchers have identified genes linked to vegetarianism. This may help explain why some people who are motivated to give up meat for ethical, environmental or health reasons, don't always adhere.
Lots of factors influence what we eat, everything from taste preferences, to budgets and culture. New research suggests genetics may also play a role.Lots of factors influence what we eat, everything from taste preferences, to budgets and culture. New research suggests genetics may also play a role.People are motivated to try a vegetarian diet for different reasons – from ethical and religious, to potential health and environmental benefits. But many people have a hard time sticking with it.
"What we can say is that these genes have something to do with vegetarianism," Yaseen says."Perhaps vegetarians have different variants of these genes that make them able to pursue a strict vegetarian diet," he explains. The study is7 habits to live a healthier life, inspired by the world's longest-lived communities
"You're looking for markers in the genome, basically trying to see if a certain trait tracks with a certain region of the genome," explains Yaseen. When they found a SNP associated with vegetarianism, they looked to see the genes around it in the same area. "One hypothesis – which is highly speculative – is that maybe there's a lipid nutrient, or nutrients, in meat that some people need and others don't," he says.
