Through history there have been some attempts to analyze taste, as well as bogus theories that have endured much longer than they should. (For example, the erroneous "tongue map" that placed difference taste buds in different areas of the tongue was created by an uncorrected game of "telephone".) We have a better understanding today, but there is still a ways to go. Umami has only been recently added to the list of basic tastes. Will there be other tastes added?
Artificial sweeteners are difficult because they have side effects and only work on the taste sensors. However, even if we can't taste sweetness, we are likely to be attracted to it. Hot Peppers trigger a reaction that tricks the body into thinking there is a hot temperature, even though there is not. (It still can be debilitating as is the case with pepper spray.) Repeated exposure can desensitize people to the hotness - and even help them to live longer. Tasty does contains a number of historical tidbits and interesting anecdotes as it looks into the history of taste. However, it feels incomplete. There is not much of an overall narrative tying everything together. There seems to be so much more that could be said about taste. We may just need to discover it first.
