Iodine: Why You Need It Why You Can’t Live Without It, 2nd Edition

David Brownstein, M.D.
Medical Alternatives Press, Michigan 2006

Iodine: Why You Need It Why You Can’t Live Without It, the first edition was published in 2004. In the past two years so much new information has emerged that an updated second edition has been published.

This second edition contains new information on iodine research and breast cancer. The author, Dr David Brownstein, provides compelling evidence that iodine deficiency can adversely affect adrenal function, immune function, the thymus gland, ovaries, prostate, hypothalamus, and pituitary axis.

Animal studies show that in iodine deficient states breast tissue shows abnormal changes and with prolonged iodine deficiency the chance of breast cancer increases. Multiple factors contribute to breast cancer but low iodine states may be significant in the higher rates that we are seeing.

In mainland Japan, where dietary iodine intake is higher, the rates of prostate cancer are lower. There appears to be an association between lower iodine levels and prostate cancer.

Modern technology has lead to the use of bromine instead of iodine in food processing. Bromide is a toxic halide that competes and binds to iodine receptors in the body, thus causing the need for even higher doses of iodine supplementation to saturate the receptors.

A comprehensive holistic lifestyle is important for good health but iodine and iodide supplementation, when indicated, can help fatigue, autoimmune disorders, immune function, hypothyroidism, Hashimoto’s thyroiditis and Grave’s Disease and may help to prevent breast and prostate cancer.

I highly recommend reading this paperback book. It is written for both healthcare professionals and our patients. Dr. Brownstein’s direct, easy to read style makes this book a learning experience that will lead you down a healthier path.
