The book is more about how artificial sweeteners are used and consumed rather than whether or not they should be used or which one is the best to use.
Susan Wittig Albert wrote the only customer review and she said something I found interesting:
I think all of the foods that are low-calorie, low-fat, low-carb and low-sugar or sugar free may have contributed to this "negative lesson".Throughout the book, De La Peña makes her thesis clear. It isn't that artificial sweeteners are "bad" for you, for there is no scientific evidence to prove their harm. But it is beginning to seem possible that we are not entirely satiated by these chemically de-calorized products and more likely to reach for another food. We have lost control of our appetites; we have become addicted to sweet-tasting chemicals; and we have allowed ourselves to be manipulated by the food industry and marketers. The real benefits of these "empty pleasures" accrue to the huge conglomerates that own these chemicals: to Monsanto, for instance, which now produces saccharin, Splenda, and NutraSweet. Artificial sweeteners, De la Peña says, have proved to be a superb, low-cost way "to move products through consumers by removing barriers to capacity." That is, if we don't have to count the calories in what we consume (and therefore risk additional pounds), we can eat as much as we want--although of course we have to buy it first. De la Peña: "The ability of the low-calorie market to expand the total market for American foods is surely proof of the ingenuity of capitalism, whether you admire or decry the results."
Perhaps even more importantly, artificial sweeteners teach us that it is indeed possible to get something for nothing, a strongly negative lesson for a high-consuming society. They are another encouragement for us to keep thoughtlessly, mindlessly stuffing ourselves with things that have no real or lasting or significant value. In accepting the false promise of the artificial sweetener industry, we have also accepted the false idea of the Free Lunch: we can consume as much as we want of anything we choose and never have to pay the price. The real price.
