The way you phrase your question and describe what you are doing makes it sound like you see having artificial foods as a must-have or a "right" or some kind of reward for not being fat or somehow a major part of this lifestyle. I don't understand why once you've found excellent health you would consider fouling it up with 20% of crappy stuff that will just bring down your vitality. For me, I just do the best I can at all times, I don't want any "cheat meals" because they simply do not appeal, they're always a let-down, I cook better than almost any restaurant out there. I understand that sometimes I can't control everything I'm going to eat so I know that in the long run a little bit of bad stuff here and there isn't going to kill me. I enjoy a craft beer now and then. I go out to a meal with friends and make the best choice I can knowing it's going to have sub-par ingredients, I choose the best-looking things at a potluck even if they have things in them I don't normally eat. I'll have a bite of a dessert now and then. I'll let my boyfriend buy cheap sushi at the store and have a few pieces knowing the fake crab meat is full of MSG. I don't dwell on these things. They're not important. But I don't make them a specific ingredient in my life and not nearly at such a huge level as 20% of my diet.
