A study has revealed people's like or dislike for Marmite is in their DNA.

Your genetic make up dictates your opinion on marmite

Whether people love or hate the yeast based spread is reportedly down to their parents, according to a new study by DNAFit - one of the UK's top genetic research centres - who have discovered your genes determine whether or not you enjoy the opinion-dividing snack.

DNAFit asked 260 adults to taste a 2g serving of Marmite before filling out a questionnaire noting their reaction to it, and after analysing the DNA of each participant, researchers discovered the make up of 15 particular single-nucleotide polymorphisms in their genes were linked to taste preference.

Principal Investigator behind the project, Thomas Roos, says: ''Our research indicates that Marmite taste preference can in large parts be attributed to our genetic blueprint, which shows that each of us is born with a tendency to be either a 'lover' or 'hater'.''

But it isn't completely down to your genes, as people can also have their taste in food products altered by the environment around them.

Thomas added: ''Like anything in genetics, taste preference is dictated by both nature and nurture. Our environment can impact our taste preference as much as the genes we are born with.''
