You are so funny!
Whole grains (and beans) before they are cooked are much less hydrated than afterwards and so, in a sense they are already dehydrated.
Vegetables on the other hand can be dehydrated but interestingly enough, after cooking they usually become smaller, unlike the grain and beans which become larger.
Also, with all the emphasis of whole grains as the center of our diet, isn't it interesting that it's the vegetales that we put the most effort into preparing?
I spent the 6th grade going to a school in Laurel Canyon while living in a house that had both views of the Valley, and the Basin, while my closest cousins lived in a house in the hills bordering Griffith Park.
Hope you and yours are enjoying the view.
Thank you, very much.
