Why Fries Taste So Good?

I found some information in chapter 5 to be quite disturbing. Obviously the smell of a food is one of the major reasons people want to eat their food. When you cook your own food you know that the actual food is what is making the enticing smell. This is not the case with fast food. The smell is engineered in a lab in most cases and then injected into your food. This is very deceitful because people don't expect the food they consume to be filled with chemicals. I think this is why this book and other books and different works like it is so crucial to enlighten our society.
