I've recently read that the white streaks or spots on nails are a symptom of acidification. I used to think it was caused from a zinc deficiency so I used to take zinc lozenges (this was a while ago) but it didn't do much. They never used to grow either, until I finished parasite and colon cleansing before the new year, and now I have very hard white tips. I still have the white spots on my nails though, that I've always had for as long as I could remember, but after switching to my raw diet, they slowly seem to start disappearing and only come up on 1-2 nails. I believe this is due to switching to a more alkaline diet. Anyone have any thoughts?
