Tasty The Art and Science of What We Eat By John McQuaid

Taste has long been considered the most basic of the five senses because its principal mission is a simple one: to discern food from everything else. Taste is a whole-body experience, and breakthroughs in genetics and microbiology are casting light not just on the experience of french fries and foie gras but the mysterious interplay of body and brain.
Tasty explains the scientific research taking place on multiple fronts: how genes shape our tastes, how the mind assembles flavors from the five senses and signals from the body's metabolic systems, why something disgusts one person and delights another, and what today's obsessions with extreme tastes tell us about the brain.

Brilliantly synthesizing science, ancient myth, philosophy, and literature, Tasty offers a delicious smorgasbord of where taste originated and where it's going—and why it changes by the day.
