It seems our tongues might be more capable than we originally realized. A research team from Philadelphia has suggested that receptor cells in the tongue are able to detect odors and smells. Their work is prompting experts to reassess whether taste and smell are combined by the brain alone or if there is some level of association between the two signals.
The group, whose findings were published in the journal Chemical Senses, began by experimenting on receptors in genetically modified mice. Following this, they moved onto cells in humans, which displayed similar properties to the mice and were found to respond to aromatic compounds.
For now, it is far too early to draw any concrete conclusion, but with further development, these ideas may be applied to persuade people to eat a healthier diet. Dr. Mehmet HakanOzdener, a specialist at the Monell Chemical Senses Center, has suggested that mildly altering the scent of some foods could reduce sugar intake
