This book is a thorough, though sometimes dry (insert your own pun here), account of how orange juice came to be a product marketed as quite pure but in many senses actually anything but.
It makes for an interesting case study of one corner of our incredibly industrialized food system. The author seems quite fascinated by the regulatory hearings which led especially to the current state of affairs with respect to not-for-concentrated orange juice; the reader feels distinctly less fascinated than the author.
One thing of interest is precisely the lack of conclusions drawn. Yes, we conclude, orange juice is quite unlike the orange in the advertisements with the straw sticking straight out of it. And, yes, the way it came to be what it is today came from complex chemical, industrial, and legal processes. But there s also not any particular reason to think that these processes are dangerous or unhealthful -- just dishonest. So what, if anything, is to be done? The author deliberately refuses to answer.
