Just last month I was bad-mouthing Primal Docs: well, to teach me a lesson, one of their members hit one out of the park today! :-)
She writes of some paleo/primal foods which are problematic with either shingles or herpes, and her discussion is very lucid and convincing. I copied the URL and trotted right over to facebook, where one of my Utah friends had been experiencing some pre-rash shingles pain -- I hope she has a look at the article! Some people resist treating their physical ills with diet and lifestyle ... as we well know! But if it's bad enough...?
In any case, this is the article I linked for her: http://primaldocs.com/opinion/4-paleo-diet-foods-to-avoid-with-herpes-or-shingles/ (and thank the gods I don't have those issues!)
