Non-perturbative results in QCD-like theories can be derived employingpositivity of the Euclidean path integral measure, as pioneered by Weingarten,Vafa, Witten. We show that positivity of the measure can be generalized toparity-invariant theories with Yukawa couplings to fundamental scalars,provided the fermions are Dirac and carry a real representation of the gaugegroup. This result allows us to demonstrate the conservation of parity andvector-like flavor symmetries in such theories, as well as to derive exactinequalities among hadrons' masses.
