This study will examine whether or not short, daily exposures change a person's ability to
detect free fatty acids in a solution by its taste. Repeated exposure should improve a
person's ability to detect free fatty acids.

The possibility that humans can taste non-esterified fatty acids (NEFA) - so-called fat
taste - is a relatively new area of research. Previous work suggests that subjects require
an average of between two and three testing sessions of approximately an hour each before
they can reliably detect NEFA, and the average number of visits to get the lowest threshold
is six. Streamlining this process is of great interest to researchers who wish to test many
people as quickly as possible. Other taste qualities, including umami and sweet, have shown
improvement in detection sensitivity in subjects that have undergone ten second exposures to
these taste qualities for 10 days upon subsequent re-testing. We seek to determine if the
same improvements can be seen with fat taste.
