For years, the battle lines have been drawn at the breakfast table. But what if the choice was never really yours to make? A study by DNAFit, dubbed "The Marmite Gene Project," has provided compelling evidence that a predisposition to loving or hating Marmite is, in fact, genetic.

The research identified 15 specific genetic markers, known as single-nucleotide polymorphisms (SNPs), that are linked to Marmite taste preference. These SNPs influence how our bodies perceive different flavours, meaning some of us are simply born with taste buds more inclined to appreciate Marmite's complex, umami-rich profile.

Further research by 23andMe identified a significant SNP near the SIX3 gene, which is known to play a role in olfaction—our sense of smell, a crucial component of taste. So, next time you find yourself in a heated debate over the black stuff, you can confidently declare you were simply born this way.
