If you eat a raw food diet, how high heat can you use to dehydrate in the oven, or do you eat dehydrated food?

It's my understanding that dehydrating is a way for raw-ists to alter food. I've found a recipe for manna bread which is cooked/dehydrated at 160-250 degrees in the oven, I'm wondering if this would be considered dehydrating, would it be considered raw bread? or is the heat to high? the only ingredient is sprouted wheat berries. Thanks.
