I'm a fan of "fresh is best".Preservatives are a larger risk to a humans health than most bacteria you may see as harmful.Many of these bacteria are not only helpful yet essential to digestion and nutrient absorbtion.Cleanliness is pleasant.Hate when my hotcakes taste like fish fried with Penquin sauce.Chillin is cool,keeps the micro's from jumpin ship.I'll have to look into the spectrum on this "blue steak" I thought it was a shade that occurs primarily right before the green and yellow collide.
