Why are Soybeans so controversial? They’re just beans, right?
If you look at the research, soybeans (whole beans or minimally processed) decrease breast cancer and prostate cancer, while providing other health benefits. They are health-beneficial, not neutral, and not dangerous. So why all the bad press?
Blogs and hype aside, here is a reasonable look at the scientific research on soybeans by Dr. Joel Fuhrman, including info about phytoestrogens, “anti-nutrients”, breast and prostate cancer, and alleged feminizing effects in men.
The shortest story: moderate whole soy food (tofu, tempeh, edamame) consumption protects against cancer and has no known drawbacks. Eating very large quantities, say 12 servings a day, can have feminizing effects in men and possibly other negative health effects. Highly processed soy-based ‘foods’, like isolated soy protein, are not associated with health benefits.
