We cleaned up what we ate, drank and got artificial chemicals like Fluoride in toothpaste, chemical based soap, shampoos, cleaning products (Amazing what White Vinegar will clean) out of the house, went with natural organics such as Hemp based soaps and cooking oils. The Rheumatoid Arthritis (RA) and Lupus symptoms went way over time, and did not return. The issue really was Multiple Chemical Sensitivities!
Overlook NOTHING in your environment nor the products you put in or on your body (Hair Coloring or getting a Perm for example). Consider things like air fresheners. Good smelling stuff can be quite toxic just as the reverse might be true.
