The researchers found a positive association between high soy intake and improved survival for breast cancer patients, particularly those with ER-positive tumors. Summary: Clinical Bottom Line This prospective […]
Comment: A study looking at the impact of phytonutrients, including soy and tea. The strongest evidence is for soy isoflavones.
