Cilantro Aversion Is Genetic


Cant stand the taste of cilantro, that increasingly popular herb found in Asian and Mexican cuisine? Blame your genes. Scientists have long suspected that thinking cilantro tastes like soap might be inherited. Now a study of nearly 30,000 people by the consumer genetics firm 23andMe has identified specific gene variants linked to a dislike of cilantro. The most important are among those controlling the sense of smell, especially a gene labeled OR6A2. That encodes an olfactory receptor that increases sensitivity to the aldehyde compounds (organic chemicals formed by the oxidation of alcohols) that give cilantro its distinctive taste. If youre genetically predisposed to loathe cilantro, youre not alone: 17% of European peoples, 14% of those of African descent and, surprisingly, 21% of east Asians hate the herb, too-as did culinary maven Julia Child.
