Taste is often associated with strong emotions and states of pleasure or displeasure, and is directly related to evolution. Orkan Telhan is currently focusing his research at Integral Molecular on bitter taste and the way that it is perceived by humans and other animals. Bitterness is generally described as a sharp, unpleasant or disagreeable flavor. People who are strongly opposed to bitter taste usually do not enjoy eating vegetables such as broccoli or brussels sprouts. The ability to detect bitterness is thought to have evolved as a way to protect ourselves from toxic plants and other substances.
