Question: I am a vegetarian and use soy milk instead of cow’s milk. I also eat some meat analogs that are soybased. How much soy is too much?
Dr. Brownstein's Answer:
My experience has clearly shown that choosing to ingest non-fermented soy products such as soy milk and soy meat analogs is not a healthy choice. These items can predispose someone to thyroid problems, as they inhibit the conversion of inactive (T4) to active (T3) thyroid hormone.
Furthermore, soy ingestion causes mineral and vitamin deficiencies. I have seen many more prostate problems in men who ingest non-fermented soy products.
I tell my patients to avoid non-fermented soy products. More information about soy can be found in my newest book, "The Soy Deception."
