"The plaintiffs are 'suffering irreparable, actual harm by being forced to continue to eat food that has too much soy in it,' according to an amended complaint filed in June. The effects have ranged from acute allergic reactions and heart problems to gastrointestinal distress and thyroid dysfunction, it says."
This is the latest blow to soy's super healthy image, writes Trib reporter Monica Eng. "Scientific studies have volleyed back and forth on whether high soy consumption reduces or increases cancer risk, inhibits mineral absorption and affects sperm concentrations. But most agree that soy, especially unfermented varieties, can cause problems with the thyroid function and digestion."
