I long ago eliminated dairy (except cheese) from my diet and replaced it with soy milk products. I find they are far more digestible and have a greater range of nutritional benefits.
Publications, articles and videos on soy and breast cancer
I have always been asked how to deal with doctors and healthcare practitioners who prohibit the consumption of soy products and continue to perpetuate the debunked myth that soy increases breast cancer risk.
I have compiled a list of peer-reviewed publications from major journals (Journal of the American Medical Association (JAMA), British Journal of Cancer, Journal of the National Cancer Institute, Journal of Nutrition and American Journal of Clinical Nutrition) that report on the results of the most recent human clinical trials on the effect of soy consumption on breast cancer risk.
I have also included peer-reviewed publications on the effect of the lunasin soy peptide on breast cancer cells and metastasis.
Also on the list are news media articles and videos on the safety of soy and its preventive effects on breast cancer.
A lot of medical and naturopathic doctors are grossly misinformed and uneducated on this topic. If doctors insist that soy consumption is bad because it promotes breast cancer, I suggest to ask them to provide you with any peer-reviewed publications, articles and human clinical results that support their contention and contradict these recent human clinical trials. If they can’t, then they should be told that they are wrong and maybe doing more harm to their patients by perpetuating the myth that soy causes human breast cancer and is bad for breast cancer survivors.
Here are some recent publications, articles and videos debunking the claim of doctors and anti-soy proponents that soy promotes breast cancer.
A. Publications reporting the recent clinical studies on the effect of soy and breast cancer risk:

4. Here is the review paper on soy and breast cancer with Dr. Helferich as co-author. Dr. Helferich’s paper in early 2000 on mice without ovaries was the basis of anti-soy’s claim that soy phytoestrogens promote tumor growth. He reversed his position on this publication.
