When some of the compound puffed into the air, a colleague remarked on its bitter taste, yet Fox tasted nothing.

These people are classified as “supertasters”.These people are classified as “supertasters”. Genetic differences in taste lead people to eat or refuse certain foods (chili, broccoli, chocolate).Genetic differences in taste lead people to eat or refuse certain foods (chili, broccoli, chocolate).

6 © 2008 Program ENERGY Program ENERGY is funded by SEPA grant number 5R25RR020469-05 A supertaster’s tongue has more tiny bumps called fungiform papillae each of which contains about 6 taste buds.

7 © 2008 Program ENERGY Program ENERGY is funded by SEPA grant number 5R25RR020469-05 Take The Test 1. Dip one end of the cotton swab into the container of blue food coloring 2. Smear the dipped end of the swab on the front part of your tongue until it is covered 3. Move your tongue around to make sure the dye spreads out.

With a magnifying glass, have a friend count the pink circles (taste buds) amid the blue background. 5. Count the taste buds that are near the front of your tongue in an area the size of a hole punch.
