Duck Feathers: One of the more-enduring urban legends about McDonald’s is that their hamburgers contain cow eyeballs. While this has not proven to be the case, the company’s Baked Hot Apple Pie does contain duck feathers, or at least an ingredient commonly derived from such. Truth can be just as strange as fiction.
Silly Putty plastic: Dimethylpolysiloxane is a form of silicone used in the stretchy toy, but it also keeps fryer oil from foaming and as such, you’ll find it in McDonald’s Filet-O-Fish and fries … or almost anything deep-fried in a fast food restaurant.
Wood (cellulose). Processed wood pulp, known as cellulose, is used in everything. Food processors use it to thicken and stabilize foods, replace fat and boost fiber content
Petroleum-derived preservatives (TBHQ). Tertiary butylhydroquinone (TBHQ) is made from compounds derived from petroleum and finds a home in processed food. McDonald’s, for example, uses it in 18 products ranging from its Fruit and Walnut Salad to Griddle Cakes to McNuggets.
Soil fertilizer (ammonium sulfate)
Ammonium sulfate is sold by chemical companies to food manufacturers as “yeast food for bread,” and many fast-food companies list the ingredient in their bakery products.
40 years ago, only around $6 billion was spent on fast food. Today that number is more like $200 billion. Not only is the fast food industry serving us disgusting food, they are making tons of money doing it.
