Dear reader,

I've had comments from readers wanting me to look at or debate specific studies that are perhaps contradictory to ones that I cited. I sometimes think that this not really productive; in the sense of 'why debate how much phytoestrogens are in foods?' when the questioner's intention seems be to help people avoid these benign/beneficial substances which are shown (at the highest levels of intake!) to prevent cancer (lowers risk of certain cancers by about 30%) and heart disease while blocking the truly harmful xenoestrogens (external sources like agricultural and industrial chemicals or plastics) from docking to cellular receptors.

And I don't really want to publish people's comments that include links that send people to other websites; especially if they are not authoritative and non-commercial. In most cases I provide my own references and will happily publish relevant comments that avoid such links; though I of course reserve the right to debate these comments with a follow up comment of my own if I disagree with the point(s) being made.

I also don't want to debate the merits of whatever "expert" someone wants to throw at me because we all know that there are plenty of voices of all levels of credibility on the Internet; many do not list references (or data-dump bogus (irrelevant or unsupportive) ones as soy critics often do), evidently preferring to hear themselves pontificate rather than to review topics from a real scientific curiosity that allows for minds to expand and change. Even the real experts often disagree, since that is the nature of the scientific method; though I have seen the rare term "proven" applied to research on soy's benefits for heart health.

I believe that YOU are smart enough to compare arguments and consider the merits of everyone's "facts" and opinions. As you see from the published comments from readers on my own blog, I do respect, read, and reply to your comments and even appreciate a "healthy" debate on topics that are also important to you. While no one is perfect (especially me), at least I aspire to know my limitations and try to do the right thing. Hopefully, you will carefully read my blog and consider me to be a trusted source providing "Honest Nutrition". Thanks for letting me share this page with you!

Am I biased?

A reader of my nutrition blog wondered if I may be biased. That's a fair question. Actually, I believe that everyone has to deal with the issue of bias, and the Scientific Method is supposed to help us all overcome these biases by focusing on valid, reproduceable data. Unfortunately, some of us seem to be trying harder than others to fairly represent unbiased data. For one example, my letter published by the cancer journal CA, the Journal of the American Cancer Society http://caonline.amcancersoc.org/cgi/eletters/55/5/319#176 rebutted an article positing that antioxidants should be avoided during cancer therapies. However, none of the references provided in that article showed any evidence of risk! In my rebuttal, I catalogued a number of studies that used nutrients with drugs or radiation therapies, which showed no harmful effects and in some cases even enhanced anticancer effects. I also pointed out the 40% of cancer patients who die of malnutrition while under their doctors' care, much of which may be preventable if physicians actually follow evidence-based medicine instead of clinging to conventional therapies and theories. Click on the title of this article to see the original report and my response. I think that you'll find that I presented relevant published scientific reports to counter a biased opinion that was not even supported by the author's references. How did that crappy opinion even get published in a peer-reviewed journal in the first place?
