The Origins of Human Diet and Medicine: Chemical Ecology (Arizona Studies in Human Ecology) (Paperback)

Editorial Reviews

Product Description

People have always been attracted to foods rich in calories, fat, and protein; yet the biblical admonition that meat be eaten "with bitter herbs" suggests that unpalatable plants play an important role in our diet. So-called primitive peoples show a surprisingly sophisticated understanding of how their bodies interact with plant chemicals, which may allow us to rediscover the origins of diet by retracing the paths of biology and culture. The domestication of the potato serves as the focus of Timothy Johns's interdisciplinary study, which forges a bold synthesis of ethnobotany and chemical ecology. The Aymara of highland Bolivia have long used varieties of potato containing potentially toxic levels of glycoalkaloids, and Johns proposes that such plants can be eaten without harm owing to human genetic modification and cultural manipulation. Drawing on additional fieldwork in Africa, he considers the evolution of the human use of plants, the ways in which humans obtain foods from among the myriad poisonous and unpalatable plants in the environment, and the consequences of this history for understanding the basis of the human diet. A natural corollary to his investigation is the origin of medicine, since the properties of plants that make them unpalatable and toxic are the same properties that make them useful pharmacologically. As our species has adapted to the use of plants, plants have become an essential part of our internal ecology. Recovering the ancient wisdom regarding our interaction with the environment preserves a fundamental part of our human heritage.

5.0 out of 5 stars reissue of "With Bitter Herbs.~ -- excellent book!, June 10, 1997

By A Customer

Reissue of John's "With Bitter Herbs...", on how humans learned how to incorporate poisonous`or bad tasting plants into their diets. Fascinating book, well worth reading.
