In her book "Gulp: Adventures on the Alimentary Canal," Mary Roach explores how people often rely on price as a measure of food quality. She notes that this reliance can lead to misconceptions, as the flavor of food isn't always a direct indicator of its overall quality. Many consumers overlook other significant factors that contribute to the value of food.

Roach emphasizes that the tendency to equate higher prices with better quality can mislead people. This perspective suggests that understanding the complexities of flavor and quality goes beyond just monetary value and requires a deeper appreciation of what food offers.
