I'm with omginternets on this one. On a spectrum of "herbivore that has roamed relatively freely and eaten a variety of vegetables according to it's nature" to "animals raised in factory farms, fed defect candy, and grown to 3x it's natural size before reaching physical maturity" to "lab grown muscle tissue" I'm sticking as close to the first one as I can, and I'm going vegetarian before making lab grown tissue a part of my diet.
