Decreased Circulating Levels of Tumor Necrosis Factor-α in Postmenopausal Women during Consumption of Soy-Containing Isoflavones

Abstract

Isoflavones may be the active components in soy responsible for the decrease of TNF-alpha found in postmenopausal women during a soy diet. This antiinflammatory effect of the isoflavones may be important in immune modulation and the prevention of bone loss and cancer.
