"While many researchers continue to map the molecular underpinnings of taste perception, others are investigating the "broccoli dilemma." Why do some hate it and some love it? Scientists are finding that we inherit a level of tasting ability that appears to infiuence what we eat.
The first indication that taste varied between individuals was found in 1931. A chemist discovered that a particular molecule was undetectable to some and bittertasting to others. In 1932, researchers found that the reaction to the chemical ran in families.
Since then researchers have found evidence that approximately 25 percent of people are supertasters and find the synthetic compound, propylthiouracil (PROP), intensely bitter. Some 50 percent find it moderately bitter; about 25 percent can't taste it at all. "
