two media reports have been published in the last recent issues of the Journal regarding fast foods 1, 2, discussing a movie named “Super size me”1 and a book entitled “Fast food nation”2. In "super size me" a 30-day fast food diet increased weight by 25 pounds and resulted in a higher blood cholesterol level. Actually this provocative film emphasizes on the “toxic environment” that is produced by the fast food restaurants 1. The book “Fast food nation” discussed the diseases transmitted via the meat processing techniques and also the flavors and aromas which had been added to the fast foods for increasing the taste by the fast food industry. These natural or artificial flavor oils both are toxic.
