The tongue can detect only sweet, salty, sour, and bitter tastes. Much of what is perceived as "taste" is actually smell. Persons who have taste problems often have a smell disorder that can make it hard to identify a food's flavor. (Flavor is a combination of taste and smell.) Taste problems can be caused by anything that interrupts the transfer of taste sensations to the brain, or by conditions that affect the way the brain interprets theses sensations. |
