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.
Until World War II, the main source of starch in the USA was tapioca but when Japan severed the supply lines of the States, they forced processors to turn to waxy maize. Amylopectin or waxy starch is now used mainly in food products, but also in the textile, adhesive, corrugating and paper industry. When feeding trials later on showed that waxy maize could produce more efficient feed gains than normal dent maize, interest in waxy maize suddenly mushroomed.
