Food in a Book?

I am reading a book called ¨Kitchen Literacy¨. It is a really good book, I chose this  book because in a future I wan to be a chef and books like this one, will help me to be better in that career. It talk  about how we lost knowledge of where food comes from and why we need to get it back. At first you will not care about, may be you will think; why do I have to know where food comes from? If I just eat the food I don´t have to do it. But once you start reading the book, you start asking yourself about this things, and it would be interesting to know about it.
