Whether Youre A Lover Or A Hater Of Cilantro Could Be In Your DNA

December 14, 2017

Polarizing debates tend to be more common in politics rather than in the kitchen, but cilantro( also known as coriander) is one of these exceptions. There are people that perfectly can’t stand the herb and likely suppose the person or persons that love it are not exactly sane.

As with many things, perceptions might seem universal but in reality, they are very personal. But it looks like some cilantro haters might actually have a genetic variation that builds the herb smell like soap. And who wants to eat a soapy taco?

A new video by the American Chemical Society’s Reactions has tackled this intriguing “controversy”, explaining the science behind this culinary schism. A genetic fluctuation on a gene in Chromosome 11, known as OR6A2 and is linked to our sense of smell, is considered the perpetrator for at least some of the cilantro haters . The genetic change might be responsible for how we perceive molecules known as aldehydes, the main odor-causing compounds of cilantro .

There are four principal molecules that produce its distinct perfume, two of them are more earthy and two of them, known as E-2-Alkenals, are more soapy. Researchers have suggested that people with the genetic variation are experiencing those molecules in a different way to the wider population. But, as the video clearly explains, the exact mechanism behind the soapy smelling and savour is still not clear.

The suggestion of a genetic reason behind the cilantro-hate has been around for a while, but the first strong proof was seen in a large genetic survey composed by 23 andMe on nearly 30,000 people from a European background, broken in two groups. To make sure the question wasn’t leading the researchers phrased their question slightly differently to the two groups; they asked one if cilantro savoured soapy, and another was asked simply if they liked the herb . In both cases, the most likely candidate for the aversion seemed to reside on the gene OR6A2.

There are also some other interesting tidbits in such studies. For example, the genetic difference demonstrated a low heritability, so if you detest it, your kids given the opportunity to stand the herb better.

According to a different analyse, the hate for the herb is not equally spread across the globe. The regions of the world that use more cilantro in their dishes- South Asia, Latin America, and the Middle East- tend to have a smaller percentage( between 4 and 7 percentage) of people that detest the herb compared to regions that use it less often, which can go beyond 20 percent.
