I think the dissonance is more pronounced in love animals / eat mistreated animals. Empathy developed presumably along with the enjoyment for taste of animal fats and protein
That dissonance can be resolved relatively easily by throwing money at the problem and eating non-mistreated animals. Love/eat is a harder moral problem IMO because there is no acceptable workaround, at least today. Someday there will be one: we'll be able to buy synthetic meat that's truly equivalent to animal meat (maybe grown with animal stem cells), and eventually the harvesting of real animals will end. But that won't mark any kind of moral evolution, only a newfound ability to not have to make a choice.
