The restricted diet is somwthing that do not effect my quality of life, it's rather the opposite. I'm doing the paleodiet and my conditions have improved alot, I'm also able to put on muscles like never before. It was a pain in the start but with good planning, and alot of mealboxes it's very manageable.
I have never been a "food enyojer" so it may be due to that but if something as easy as diet can make you feel well, I say it's a quality booster not the opposite.
And in my oponion, the most important is the rotation in a diet. Nasty food intollerences (due to candida causing leaky gut) can make you feel even worse than the candida "toxins".
