This would have interesting implications for folklore common in some East Asian countries, particularly China, where meat flavor is "enhanced" by animal suffering at time of death. I must say the practices are abhorrent - particularly regarding the slaughter of intelligent, sensitive animals like dogs and pigs.
The article make mention of flavour, and I don't think you need to try to scientifically rationalize what can be sufficiently explained by human cruelty. In fact, based upon these findings I'd expect eating tortured meat to be less enjoyable than that relaxed kind.
