The same or similar aldehydes are also found in soaps and lotions and the bug family of insects. , Much of the variation in tasting of PTC is associated with polymorphism at the TAS2R38 taste receptor gene. In 1976, an inverse relationship between taster status for PTC and for a bitter component of the fruit of the tree Antidesma bunius was discovered. To enhance the taste, try adding lemon juice, ginger, or green apple. "Flavor chemists have found that cilantro aroma is created by a half-dozen or so substances, and most of these are modified fragments of fat molecules called aldehydes. Many people can't.

Celery (Apium graveolens) is a marshland plant in the family Apiaceae that has been cultivated as a vegetable since antiquity.  The widespread occurrence of non-taster alleles at intermediate frequencies, much more common than recessive alleles conferring genetic disease, across many isolated populations, suggests that this polymorphism may have been maintained through balancing selection. It has the unusual property that it either tastes very bitter or is virtually tasteless, depending on the genetic makeup of the taster. This uses fresh celery but also tastes really fresh! Celery has a mild and strong taste at the same time, giving it a bold flavor.  The ability to taste PTC is an ancestral trait of hominids that has been independently lost in humans and chimpanzees, through distinct mutations at TAS2R38. Celeriac is often cooked and added to mixed vegetable dishes. Genes related to the sense of smell, called olfactory genes, come into play with the taste of cilantro.

One study has found that non-smokers and those not habituated to coffee or tea have a statistically higher percentage of tasting PTC than the general population. On the other hand, heavy cigarette smokers are more likely to have high PTC and PROP thresholds (i.e.  Some studies have shown that homozygous tasters experience a more intense bitterness than people that are heterozygous; other studies have indicated that another gene may determine taste sensitivity.

Genetic engineering has raised the question of whether its products create unintended health effects for consumers, but how do conventionally bred products compare along the continuum of genetic modification? From The Great, Big Golden Answer to “Why do [They] do that thing I saw/heard/read (once on the Internet)?” 1 - “Never ask why until you ask if.” See: Your Question Is Naughty!
