"Chew on This" is an eye-opening look at fast food: how it's made, what it contains and the ways in which in affects the body. The book provides a history of the fast food industry. Readers are given a look at the manufacture and distribution of foods from tours of feedlots and a chicken processing plant through to the pricing and marketing of products and the pay and working conditions of employees.
The writers clearly have a strong point of view that they support with statistics and published research. Though the text can be stomach turning in places, the authors make a strong argument against the marketing tactics that target children. For example, McDonald's distributes 1.5 billion toys a year. In addition to documenting the manufacture of fast food burgers, fries and shakes, the book also provides readers with an opportunity to compare healthy and damaged organs.
