Scientists Protest Soy Approval

By Dr. Daniel Sheehan and Dr. Daniel Doerge

Summary: In this shocking letter, two FDA toxicology experts officially protest their agencys decision to grant soy a health claim in 1999. “We oppose this health claim,” the researchers write, “because there is abundant evidence that some of the isoflavones found in soy…demonstrate toxicity in estrogen-sensitive tissues and in the thyroid.” Effects of such toxicity in animal testing, they add, include breast cancer, thyroiditis, abnormal brain and reproductive development (especially in infants fed soy), goiter, bodily deformities and vascular dementia—just to name a few. Granted, the researchers say, these effects are based on animal testing, but short of testing potential poisons directly on humans, animal tests “are the front line in evaluating toxicity, since they predict, with good accuracy, adverse effects in humans.” Something to think about that next time you opt for that soy-milk latte.

Tragedy and Hype: The Third International Soy Symposium

By Sally Fallon and Mary G. Enig, PhD

Summary: Reflections on the Third International Soy Symposium by two of the most outspoken critics of processed soy products. “Far from being the perfect food,” Fallon and Enig write, “modern soy products contain antinutrients and toxins, and they interfere with the absorption of vitamins and minerals.” The authors also cite the infamous letter of Drs. Dan Sheehan and Daniel Doerge, two members of the FDA’s toxicology department who tried in vain to stop their agency from awarding soy an official health claim. From Nexus Magazine, 2000.
