TEX-ed March 22, 2013)A fundamental ingredient in wormhole physics is the flaring-out condition at the throat which,in classical general relativity, entails the violation of the null energy condition. In this work, wepresent the most general conditions in the context of modified gravity, in which the matter threadingthe wormhole throat satisfies all of the energy conditions, and it is the higher order curvatureterms, which may be interpreted as a gravitational fluid, that support these nonstandard wormholegeometries. Thus, we explicitly show that wormhole geometries can be theoretically constructedwithout the presence of exotic matter, but are sustained in the context of modified gravity.
