Oats are a natural preservative as well. Put some oat flour (just grind up the flakes) in bread to get longer shelf life.

Oats are delicious. For an amazing, light pancake, substitute 1/3 oat flour, 1/3 rice flour, 1/3 wheat flour for the flour in the recipe. You're welcome.

Oat meal (flakes) store for a long time, oat groats store forever (much like wheat berries). Oatmeal cookies don't last at all, tho. They seem to walk right off the cookie sheet. Add chocolate chips to the recipe and well, I have moderate self-control but not when we're talking oatmeal chocolate chip cookies.
