Depth of consumer knowledge regarding non-nutritive, artificial, or high-intensity sweeteners (NNS) is incompletely understood. NNS can be identified by their chemical name (CN), trade name (TN), or by the GRAS plant that is responsible for the sweet taste. Consumers appear to be unable to effectively identify NNS, especially with respect to CN. Food ingredient labelling identifies NNS by CN or GRAS ingredient. Because consumers lack adequate NNS knowledge, they may not understand whether they consume NNS and the importance of NNS to dietary health may be difficult to determine.
