Researchers have long noted that people adopt vegetarianism for varied reasons, with health, environmental concerns, and animal welfare topping the list in Western cultures. But how compelling are these factors for non-vegetarians on the fence?
A University of California, Davis, psychology research team surveyed 8,000 individuals of diverse ages, ethnicities, and backgrounds in both the United States and the Netherlands to pinpoint what motivates non-vegetarians to make the switch.
A Paradox for Advocacy
The findings? Health emerges as the primary draw for newcomers to vegetarianism, outpacing environmental and animal rights concerns. Yet, those most dedicated to the lifestyle are fueled by ethics—environment or animal welfare.
“The most common reason people say they are going vegetarian has to do with health… But people who are primarily driven by health motives generally respond the least to vegetarian advocacy,” notes Christopher J. Hopwood, psychology professor and co-author of the study.
Health-focused individuals often align with conventionality and traditional masculinity traits, while ethics-driven vegetarians score high on curiosity, openness to experience, volunteering, and artistic interests.
