  We derive the Deep Inelastic anti-quark distribution in a baryon at a low
value of Q^2 using the variational principle of Quantum HadronDynamics, an
alternative formulation of Quantum ChromoDynamics. It is determined by a
variational approach generalizing the ``valence'' quark approximation of
earlier papers. We find that the ``primordial'' anti-quarks carry less than a
percent of the baryon momentum. In the limit of chiral symmetry and N_c to
infinity, we show that the anti-quark content of the proton vanishes at low Q^2
