Candida was a cause of multiple chemical sensitivity for me. The first time I went on the candida diet, my chemical sensitivity almost went away completely. Though I still had the mercury from amalgams, the diet obviously took a big load off my immune system. So I stopped reacting so badly to perfumes/cigarette smoke/cleaning products etc. Big change and much relief.

I was then able to clean the house, polish the furniture with no symptoms. I used to get very ill when cleaning the house before treating candida and would go white in the face and look and feel absolutely wretched.

So it seems to be the less load on the immunity, the less reactions.
