Description
Past research has shown that long-term dietary consumption of soy products, containing isoflavones, has beneficial effects on cardiovascular health, bone mineral density, and risks for certain cancers. In addition, there is evidence that long-term dietary soy consumption improves cognitive performance. However, no such studies have examined the impact of acute doses of soy isoflavones on cognition. Therefore, this experiment was designed to evaluate whether acute doses of soy isoflavones would enhance memory in young adults who were not regular consumers of soy products. The results indicate that individuals consuming soy isoflavones, compared to control participants, did not show enhanced memory on visual-spatial or verbal tasks. These results suggest that the cognitive benefits derived from isoflavone consumption may be primarily due to long-term dietary soy intake and not acute consumption. Health benefits associated with consumption of soy-based food products have previously been identified, including reducing the risk of coronary heart disease (Clarkson, Anthony, & Hughes, 1995) and some forms of cancer (Aldercreutz, Honjo, Higashi, Fotsis, Hamalainen, Hasegawa, & Okada, 1991), positively impacting bone density (Ho, Chan, Yi, Wong, & Leung, 2001), and improving cognitive function (File, Jarrett, Fluck, Duffy, Casey, & Wiseman, 2001; Kritz-Silverstein, Von Muhlen, Barrett-Connor, & Bressel, 2003). While some epidemiological and clinical data have suggested a relationship between dietary soy consumption and health, the evidence related to improvements on cognitive function are less conclusive (White, Petrovitch, Ross, Masaki, Hardman, Nelson, Davis, & Markesbery, 2000). The soy and postmenopausal health in aging study (SOPHIA) evaluated the impact of 110 mg of soy isoflavones on cognition
