The Taste Gene -- Psychobiologists Find Genetic Component in Children's Food Preference

ScienceDaily () -- In the first study to link taste genes to behavior in children, researchers looked at how natural variations in a recently discovered taste gene affected sensitivity to bitter tastes and food preferences in a group of children and adults. Collecting genetic samples from 143 children and their mothers, the researchers showed moms and kids who had at least one bitter-sensitive region in the gene were generally able to detect even a hint of bitter flavor in a test drink. The same group of children, carrying one or two bitter-sensitive regions of a gene, also preferred higher concentrations of sucrose solutions and had stronger preferences for sweet-tasting food and beverages than did the bitter-insensitive kids.
