The six tastes and their corresponding emotions are:
Sweet-satisfaction; contentment; fulfilled
Sour- discernment; insightful; heightened awareness
Salty-desire; zest for life; passionate
Pungent- extroverted; driven; ambitious
Bitter -dynamic; focused; cool-headed
Astringent- introspective; mental clarity; reflective; composed

If any one of these tastes is missing in the diet over a long period of time, or is present in excess, it can cause an emotional and physiological imbalance.
