Digestion involves heavy duty mechanical crushing and grinding, at least three sets of enyzymes, dissolving in acid strong enough cut metal, more mechanical squeezing action, and anything microbes can do to the remainder, over the course of several hours. Up against that, ageing a steak is not going to make a difference. As for bread, if anything, it is easier to digest than something "natural" like raw grains since it has less fibre and anti-nutrients. The food in question is ever more "processed", since it seems to be made mostly of the base nutritional chemicals.
