II. Nutrition
A third food that humans consume is the substances that are carbohydrates. Carbohydrates are found in particular in potatoes, for example, in lentils and beans, and of course in all types of grain. The carbohydrates are in there. In a great many of these substances, either sugar is directly contained, which we always take with our food, or sugar is produced directly from these carbohydrates by converting what we take in with the potato, for example. Potatoes contain mostly starch. This starch paste is first converted into dextrin and then into sugar in our bodies. So when you eat potatoes, you are actually nourishing yourself with sugar, because the potato paste, the starch paste, is converted into sugar in the human body. Isn't it true that grapes, for example, contain a lot of this sugar, and so does alcohol. What alcohol is for a person is actually based not only on the alcohol itself but also on its sugar content. Sugar is produced in the human organism from alcohol.
