In the Platonic school of philosophy, the Demiurge is a deity who fashions the physical world in the light of eternal ideas. In the Timaeus, Plato credits the Demiurge with taking preexisting materials of chaos and arranging them in accordance with the models of eternal forms.
Oatmeal does not turn into starch, because it is already mostly starch. In a serving of 1/2 cup of dry old-fashioned oats, 22 g of the 27 g of total carbohydrates are starches. Starches correspond to a chain of glucose, or sugar, linked together.
Because oatmeal is a whole grain, it contains complex carbohydrates, such as dietary fiber. You'll get 28 grams of total carbohydrate from plain oatmeal, 4 of which come from dietary fiber. Your body relies on fiber to help maintain proper digestion.
