Explanation:

Cynthia Crossen wrote an article called "A Culinary Wasteland", in which she reviews the book "Fast Food Nation" by Eric Schlosser. In Crossen's opinion, the book offers only one point of view since, according to her, Schlosser did not allow fast food defenders or aficionados to share their own perspectives, even if it were only for him to rebut. She also claims the statistics offered by Schlosser in his book are not trustworthy:

[...] I was disturbed by Mr. Schlosser's cavalier manipulation of data, which produced some startling -- and, frankly, unbelievable -- "facts." I had a hard time accepting that on a typical day in the U.S., "one-quarter of the adult population visits a fast-food restaurant." In his notes, Mr. Schlosser acknowledges that "this is my own estimate," based on information from the National Restaurant Association...

Crossen believes Schlosser wants things to be his own way. In her opinion, he is demonizing fast food without thoroughly researching all sides there are to it, or even really defining what fast food is. To Crossen, the book is superficial, "even childish" in its presentation of empty facts and irrelevant information.
