Jayden Simmons : I'm a nutritional therapist with a 9-year old son -- he has grown up with nutrient-dense, healthy foods, and lots of examination of our cultural marketing, food-buying, and other food-related patterns. When I saw this articleon Internet, I had to get it -- for research. It's very well designed and written -- clearly walking the young reader through the different components of our failed industrial food system.
Victoria Lawson : Companies work SO hard to convince your children to eat junk food, simply so they can make money. this book breaks down those messages and allows a child (or adult) to see just how they are getting played. the message is always "you are in control of your health", but not when huge corporations trick you countless times a day to sabotage you. all the grossness in advertising is shown in kid-friendly and empowering language.
