A gene has been identified as a likely cause of why some people enjoy the smell and taste of coriander (also known as cilantro) while others have exactly the opposite reaction to the point of repulsion. Depending on ancestry, somewhere between 3% and 21% of the population associate it with unpleasant taste, including a combination of soap and vomit, or say that it is similar to the foul smelling odor emitted by stinkbugs. This is due to the presence of aldehyde chemicals, which are present in soap, various detergents, coriander, several species of stinkbugs and cinnamon.
