'Men think eating meat makes them more manly'
Professor Hank Rothgerber from the Bellarmine University in Louisville said that meat eating was linked with "manhood, power and virility".
"There is a group of manly men who swear off what they call chick food, and they seek a double whopper to declare their manhood," the Daily Mail quoted Rothgerber as saying.
"Meat consumption is a symbol of patriarchy resulting from its long-held alliance with manhood, power, and virility," Rothgerber said.
In the study, men questioned said animals "just taste too good to not eat them" whereas women were more apologetic about eating meat.
The study surveyed 125 undergraduate psychology students for one study, and 89 for the second. They were all white middle class students in their late teens and early 20s. "Men expressed more favourable attitudes toward eating meat, denied animal suffering, believed that animals were lower in a hierarchy than humans, provided religious and health justifications for consuming animals, and believed that it was human destiny to eat meat," Rothberger said.
"These are direct, unapologetic strategies that embrace eating meat and justify the practice," he told NBC News.
