"Taste Bud" For Fatty Foods Found

Scientists have found that the tongue has taste receptors for fat, which might explain why we like fried foods. Conventionally, experts have thought that the tongue detects five tastes - sweet, salty, sour, bitter and umami taste for protein rich foods. But tests on rodents showed a receptor on the tongue tastes fat - it is not known if it is the same for humans. The work by French researchers from the University of Burgundy appears in the Journal of Clinical Investigation.
