Are You a Super Taster?
Classifications are based on sensitivity to a chemical, known as PROP for short, which is similar to compounds that make foods such as broccoli and Brussels sprouts taste bitter to some people. Some scientists dispute the association between sensitivity to PROP and body size, but researchers at Yale University and University of Connecticut produced results similar to Tepper's.
As we age, our sense of smell and taste diminishes, but the average person has more than enough taste buds for a lifetime.
To determine if you are a super taster, place a gummed ring, the kind used to reinforce loose-leaf paper, on your tongue with one edge touching the middle and the other touching the side. Use a cotton swab to dab blue food coloring in the center. Remove the ring and, using a magnifying glass, count the pink circles, called fungiform papillae, on the blue background. If there are more than 30 circles in the ring, you are a super taster. The norm is between 10 and 30, and if you only find 5 to 10, you are a non-taster.
