Which of the following is true regarding supertasters?
A) Supertasters have many more taste buds than non-supertasters.
B) Less than 1% of the population are supertasters.
C) Supertasters prefer sweet and fatty foods.
D) The tongues of supertasters are physiologically identical to non-supertasters.
Answer: A
Rationale: Supertasters, comprising about 25% of the population, are especially sensitive to bitter tastes such as those of broccoli and black coffee. As a result, they tend to dislike fatty and sweet foods. Compared to non-supertasters, supertasters have many times more papillae, and therefore taste buds.
