We discuss several assumptions on the heavy quark axial vector matrix elements of the proton. We emphasize the role of the axial vector isoscalar neutral current induced by the axial-vector-current anomaly. Then we re-evaluate the standard model predictions for nuclear spin-dependent parity violating effects in light atoms taking into account the EMC results and the theoretical prediction of the quark spin content of the proton. © 1990.
