Now parasites are another huge, often unrealized issue for people. That bridge is what you cross after you deal with mercury and other heavy metals, so I haven't done that yet, but it's coming. In the meantime, for your researching pleasure, here is the fine link someone sent me. Dr. Hulda Clark.org. Dr. Clark is a very big name in the topic of parasites. This site has tons of interesting and gross info. Have fun. When I learn more, I'll come back and post it!
