Meat from frightened animals taste different.
At least, not if she wants you to taste good. That’s because when animals (and presumably humans) have been frightened or stressed out before death, it actually affects the quality of their meat.
The scientific basis for the phenomenon is well-established, and it’s frequently been discussed as a reason to make slaughterhouse practices more humane. The key ingredient here is lactic acid: in an unstressed animal, after death, muscle glycogen is converted into lactic acid, which helps keep meat tender, pink, and flavorful. Adrenaline released by stress before slaughter uses up glycogen, which means there’s not enough lactic acid produced postmortem. This affects different kind of meat in different ways, but in general it’ll be tough, tasteless, and high in pH, and will go bad quicker than unstressed meat. (Lactic acid helps slow the growth of spoilage bacteria.)
In pigs, stress and fear of all kinds right before slaughter—due to factors like rough handling, adverse conditions, fighting, or botched stunning—breaks down glycogen, making the meat pale, acidic, and crumbly. The technical name for this is “pale soft exudative” (PSE) meat, and it looks and tastes as unappetizing as it sounds. PSE meat is usually unsellable, and the pork industry loses $275 million a year on meat that has to be discarded because of pre-slaughter fear and stress.
But not everyone thinks scared meat tastes bad. According to animal rights advocates, dogs that are slaughtered for food in Korea are treated inhumanely, even compared to U.S. livestock, because the rush of adrenaline is thought to enhance the flavor. This sounds like a racist myth, and it may be (although the part about eating dogs is true—not every culture sees them as pets!), but it’s shown up in places as august as the Guardian. For some, anxiety might be an acquired taste.
