Salt, Sugar, Fat by Michael Moss is an investigatory report into processed food industry practices that was published in 2013. The book is American-centric and doesn’t necessarily hold across all cultures and nations but in so much as America is a cultural harbinger for a lot of the world it is worthwhile using them as a case study. But first, a caveat, Moss is not a scientist, he approaches the work from a journalistic bent and I found some of his writing on some of the more scientific elements to be alarmist and a touch misleading at times.
