I would be more concerned with where you get your food from than what happens when you cook it. "Corporate" chicken products, pork products, and beef products are bad news on a lot of levels.
You're fortunate to live in the Dallas area. There are a lot of alternative markets where you can buy pastured chicken and beef. They are true organic sources versus places like Whole Foods where the quality is better than most stores but the definition of "organic" has been grayed by the need to supply high volumes of food.
Check out "
