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.
Yes, oatmeal is a complex carbohydrate. It is typically used by athletes of all kinds for a great source of slow burning carbohydrates. However, this applies to oatmeal that is sugar free, being that sugar is a simple carbohydrate, oatmeal with sugar is both a simple and complex carbohydrate. Hope this helps :)
