Updated October 2026

Quick Answer

Soy Isoflavones Cognition Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: 1 2 3 4 5 6 7 8 7 8 9 n Increased life expectancy has contributed to an aging population, with global dementia cases estimated to rise from 57.4 million in 2019 to 152.8 million in 2050 [].

(2025); evidence level 2] - Phytonutrients are thought to support healthy cognitive and cerebrovascular function, by reducing oxidative stress and neuroinflammation, which are associated with neuronal damage and can increase the risk of age-related cognitive decline (ARCD) [,,]. [West Laura M. (2025); evidence level 2] - There is increasing evidence reporting that consumption of soy foods can significantly affect health []. [Chen Li-Ru (2021); evidence level 3] - In addition, there is a significant connection between increased soybean consumption and a decreased cancer risk []. [Chen Li-Ru (2021); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
