The podcast episodes explore various aspects of taste perception, including how individual genetic differences determine how people perceive and experience flavors.

Several episodes delve into the science behind taste, examining the neural circuits and biological mechanisms underlying the perception of the five basic tastes: sweet, sour, bitter, salty, and umami. "Your taste is unique" and "Dr. Charles Zuker: The Biology of Taste Perception & Sugar Craving" are two episodes that focus on the subjective nature of taste and the neurobiology of taste perception.

Other episodes, such as "How You Can Taste Food Like A Flavor Chemist" and "To salt or not to salt?", explore the role of aroma, texture, and cultural significance in shaping our perception and appreciation of different tastes. The episodes also examine how processing and marketing of foods can impact taste preferences and cravings.
