Q: When can organic soy products be introduced into the diet?

A: The short answer is never. Soy products of all kinds (tofu, flour, sauce, etc.) contain a substance that blocks absorption of nutrients, besides having a high fat content. A great deal of research material has proven the toxicity of soy, even when grown organically. The hype claiming soy’s usefulness in preventing breast cancer has turned out to be unsubstantiated and the opposite of truth: soy is likely to stimulate malignancy.
