Taste and Smell

34 Supertasters

Learning Objectives

Be able to describe what it means to be a non-taster, a taster, or a supertaster.

Know what is the typical distribution of tasters and supertasters in a population.

Supertasters are people with a genetic difference that means they have an extra kind of taste cell in their taste buds, one which signals a bitter sensation in response to PROP (6-n-propylthiouracil) or PTC (Phenylthiocarbamide).

A supertaster is a person who is able to taste things to a more extreme level. This is a result from the extra number of fungiform papillae on the tongue. With this extra amount of papillae, the individual is able to taste things better and more potently. A non-taster would be a person with much less fungiform papillae on their tongue, resulting in a lesser sense of taste. A taster is what is considered to be in between a non-taster and a supertaster.

In the 1960’s Roland Fischer was the first to link the ability to taste PTC to food preference and body type. Today, PROP has replaced PTC in taste research because of a faint sulfurous odor and safety concerns with PTC. Most estimates suggest that 25% of the population are nontasters, 50% are medium tasters, and 25% are supertasters. Women are more likely to be supertasters, as are people from Asia, South America, and Africa. Female supertasters tend to have a lower body mass index and better cardiovascular health. This may be due to the fact that supertasters do not have a high predilection for sweet or high-fat foods.

 

Fig.4.6.1. In this figure, you can visualize the difference between a supertaster and a nontaster. The supertaster has many more papillae than the nontaster evidently. You can see why someone who is a supertaster would be more picky in their eating choices, as they have an overwhelming amount of senses reacting to what they put in their mouth. (Credit: Jarod Davis.
