Well some may say Oats is Oats but Scottish porridge Oats seem to be the favourite amongst most.I always keep a big box of Reddy Brek on hand for when the pallet struggles to get the grainy veriety down and also add it to my shakes.Myprotien do a great powder version too for the same purpose if you want a specific brand.
