Logical Fallacy

I found the example of diet products, specifically diet coke fit into logical fallacy well. Advertisements for these products say that they have reduced to zero calories, and are therefore healthier for you. Diet Coke, for example has no calories, but uses a sugar substitute that can have negative health effects. In addition to the sugar substitutes, Coke uses additives and preservatives that also prove to be unhealthy. And on top of all of that, Coke, is still Coke and is not generally a good choice on a day to day basis health wise. In addition to diet Coke, power bars and granola bars are thought to be an extremely healthy snack. While the bars do generally have whole grains, or fruit in them, these bars are also loaded with sugar and carbohydrates, which are good if you are participating in strenuous physical activity, but not so good otherwise. These two examples both fall into the category of hasty generalization, because the ads for these products tell us that they are diet and have fruit and whole grains. Fruit and whole grains are good for you, so therefore, power bars are good for you. Or that diet products will help you to lose weight, so if you drink diet Coke, then you will lose weight. Neither of these statements have any basis in truth with these product, but many people are lead to think that way.
