Jane and Ann Esselstyn show how to prepare raw rolled oats: by mixing them with fruits, berries and seeds. Ann Esselstyn's raw rolled oats + grapes recipe actually made it to the cover page of their cookbook: The Prevent and Reverse Heart Disease Cookbook (288 pages, 2014) by Jane & Ann Esselstyn.
A nice video with 2 points: (a) Don't eat raw oats in their dry form; moisten them with something like plant-absed milk or grapes or … (b) Soaking of grains, beans, nuts and seeds helps us reduce phytic acid (phytates). Such reduction is helpful in increasing mineral absorption (of zinc and iron, for example).
