The evils of the American diet are in the high sugar and high carbohydrate content of most of our foods. The majority of the American diet is comprised of manufactured food like substances that contain synthetic edible chemicals that have no nutritional value beyond their caloric value. Eating manufactured food like substances that are high in calories and low in nutrition over a long period of time leads to heart disease, obesity and diabetes. Chipotle's burrito's (and now their melted cheese) is calorically dense, no argument there. However, the calories come from real, whole foods that give our bodies nutrients. I recommend 2 books, both by the same author: The Calorie Myth and The Smarter Science Of Slim. You will find an evidence based case for the health benefits of real, whole foods and then you won't be so afraid of Chipotle burritos.
