The NIH has assigned an independent scientific panel to review the latest research about the safety of soy baby formula and the estrogen genistein found in soy products.

The consumption of soy products has been rising in recent years even though concerns exist about the effect of soy estrogens on human development and reproduction. Soybased drinks represented the fastest-growing food category worldwide from 2003 to 2004.

The Center for the Evaluation of Risks to Human Reproduction, part of the National Institute of Environmental Health Sciences and the National Toxicology Program, has convened a committee of 14 scientists to review the safety of soy known to contain biologically phytoestrogens.  Genistein, a flavonoid found in soy, is known to mimic the effect of estrogen in humans. The panel will also be expected to note what additional research is needed.

A coalition of soy trade groups have objected to the review, claiming that soy-based baby formula has been used for more than 35 years. The statement also said findings from animal research cannot reliably be extrapolated to humans.

However, this raises the question: should history of use be a claim for safety?

A final report will be posted online in late May to help consumers make informed choices. If follow-up action is required, it will be left up to regulatory agencies such as the Food and Drug Administration.
