A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia—with the help of the right bacteria, according to a new discovery led by researchers at the University of Pittsburgh Graduate School of Public Health.
Their study, published today in the journal Alzheimer's & Dementia: Translational Research & Clinical Interventions, reports that elderly Japanese men and women who produce
“White matter lesions are significant risk factors for cognitive decline, dementia and all-cause mortality,” said lead author Akira Sekikawa, M.D., Ph.D., associate professor of epidemiology at Pitt Public Health. “We found 50% more white matter lesions in people who cannot produce equol compared to people who can produce it, which is a surprisingly huge effect.”
To obtain this result, Sekikawa’s research team measured equol levels within the blood of 91 elderly Japanese participants with normal cognition. Participants were sorted by their equol production status, and then six to nine years later underwent brain imaging to detect levels of white matter lesions and deposits of amyloid-beta, which is the suspected molecular cause of Alzheimer’s disease.
