"This comprehensive book is welcome in that it not only covers the quality of crops in separate chapters on vegetables, fruit and cereal grains but it also deals, in equal measure, with the quality of meat, milk products and eggs." (The Biologist, March 2014) “Everyone with a serious interest in the differences between organic and conventional food should have this book on their coffee table or bookshelf, because it is the most comprehensive and objective library of present evidence.”  (Int. J. Environment & Pollution, 1 May 2013)"Summing Up: Recommended. Upper-division undergraduates through professionals; general readers." (Choice, 1 December 2012)"This book by Professor Blair is a very valuable analysis of how organic food production affects food quality, and the conclusions and suggestions should be of great interest to all sectors of the food industry, including researchers and producers. Hopefully the book will also benefit consumers by encouraging the media and the food industry to present a more accurate picture of the relative quality of conventional and organic foods." (Asian-Australasian Journal of Animal Science, 1 May 2012)"This is a remarkable book . . . Everyone with a serious interest in the differences between organic and conventional food should have this book on their coffee table or bookshelf because it is the most comprehensive and objective library of present evidence." (Prof. John Hodges, Food and Nutrition Sciences)"Dr. Blair's book is a comprehensive and balanced review of the scientific literature related to the organic versus conventional debate. . . . Each chapter provides an unbiased overview of the literature related to a particular food item and lets the reader decide if their preference for or against a particular organic food is supported by research." (Journal of Applied Poultry Research, 1 December 2012) "This unique book gives an objective and thorough view of a major issue in health, nutrition, food quality, the environment and food production systems and is of interest to consumers, farmers, nutritionists, medical specialists, environmentalists and businesses in the food chain."
