While most singles consider looks, personality and career ambition among the top most important qualities for a potential partner, for some, eating habits can make or break a relationship.
According to recent survey, Love Bites, 30per cent of meat eaters said they would not date a vegetarian or vegan.
Today.com and Match.com polled 4,000 singles and found that sharing a common passion for food was a top priority for carnivores while vegetarians were far less bothered by their mate's culinary preferences.
Biological anthropologist and Match.com's chief scientific advisor, Dr Helen Fisher, attached many theories to the discovery, many of which are rooted in man's evolutionary background.
First and foremost is that sharing food is a ritual central to all members of the animal kingdom.
She explained on Today.com: 'It's so common in the animal world to give food for sex that it's called the nuptial gift. Mankind's first luxury was meat, and when carnivores share food - what they are sharing is this luxury.
'It's more than just cultural, it's instinctual.'
