Recent {sup 56}Fe(e,e`) datal at momentum transfer {vert_bar}q{vert_bar} = 1.14 GeV displays behavior which is qualitatively different from that of lower momentum transfers where relativistic mean field theory provides a semiquantitative understanding. An explanation of this difference is offered based on an analysis of the longitudinal response in nuclear matter. An ansatz is made for the self-energy functions in the nuclear medium which suppresses medium effects for momenta above the nucleon mass scale. This suppression is shown in a local density calculation to give consistent qualitative agreement with both the low and high momentum transfer data, although the experimental longitudinal response is still systematically below the calculation at high energy transfers. The calculation provides motivation for further experimental investigations in the momentum transfer region between 0.5 and 1.0 GeV.
