Supertaster

Supertaster is a term used to describe individuals who have a heightened sense of taste, particularly in relation to the intensity of flavors. This heightened sensitivity is often attributed to a higher density of fungiform papillae, the taste buds that are found on the surface of the tongue.

Overview

The concept of the supertaster was first introduced by Dr. Linda Bartoshuk, a psychologist specializing in the study of taste, in the 1990s. Supertasters are thought to make up approximately 25% of the population, with the remaining 75% divided between medium tasters and non-tasters.

Supertasters often have a strong aversion to foods that have a bitter taste, such as certain vegetables, coffee, and alcohol. This is due to their heightened sensitivity to the chemical compounds found in these foods.

Genetics

The ability to be a supertaster is believed to be genetic, with certain individuals inheriting a variant of the TAS2R38 gene that increases their sensitivity to taste. This gene is responsible for the ability to taste a chemical compound known as propylthiouracil (PROP), which is found in many bitter foods.

Health implications

While being a supertaster can have its advantages, such as a heightened enjoyment of certain foods, it can also have health implications. Supertasters often have a lower preference for high-fat and high-sugar foods, which can lead to a lower risk of heart disease and diabetes. However, their aversion to certain vegetables can also lead to a lower intake of important nutrients.

Testing

Testing for supertasting often involves a simple taste test, in which the individual is asked to taste a piece of paper treated with a PROP solution. Those who find the taste extremely bitter are likely to be supertasters.
