We prove that the 1/N corrections to the baryon axial current matrix elements
are proportional to their lowest order values. This implies that the first
correction to axial current coupling constant ratios vanishes, and that the
$SU(2N_f)$ spin-flavor symmetry relations are only violated at second order in
1/N.
