Question: is old fashion oats the same as rolled oats

Context: Rolled oats that are sold as porridge oats usually have had the tough bran removed. They have often, but not always, been lightly baked or pressure-cooked or ``processed'' in some fashion. Thick-rolled oats are large whole flakes, and thin-rolled oats are smaller, fragmented flakes. Oat flakes that are simply rolled whole oats without further processing can be cooked into a porridge and eaten as ``old-fashioned'' oats, but more highly fragmented and processed rolled oats absorb water much more easily and therefore cook faster into a porridge, so they are sometimes called ``quick'' or ``instant'' oats. Rolled oats are most often the main ingredient in granola and muesli.
