In the last episode of dr. Oz show (in the season currently aired in America: I remind you that in Italy they broadcast the episodes of the previous season), the famous doctor talked about calorie-free or zero-calorie foods. In the United States, many calorie-free products are depopulated, and in Italy too most of these are on the market: for example, all zero-calorie drinks, sweeteners such as stevia and erythritol, but also sauces, jellies and condiments, as for example those of Walden Farms, of which I have spoken here . On the Vitamin Center website you can also find an oil-like product that you sprinkle on pans to cook calorie-free foods, such as omelettes, and which is called Pam.  In America there is also whipped cream without calories, smoothies without calories, spoon desserts without calories such as fruit jellies: soon these products will also invade the Italian market.

But what’s in calorie-free foods? The fact that they are calorie-free does not mean that they are made of clouds: they contain substances that allow them to have a consistency, other substances that give them flavor, and finally substances that add a sweet or salty taste (butter calorie-free peanuts from Walden Farms, for example). When we drink something without calories, we are ingesting substances that we don’t know the name of, often, and we don’t know if they do something or not in our body. In short, we often ignore them.
