The impact of a prebiotic-rich diet and/or probiotic supplements on human cognition: Secondary outcomes from the ‘Gut Feelings’ randomised controlled trial
We found suggestive evidence of a probiotic-induced improvement in working memory, and prebiotic-induced impairment in processing speed. However, the evidence remains inconclusive regarding any cognitive benefit or harm induced by the probiotic, prebiotic diet, or synbiotic treatments. Larger intervention studies are recommended, with inclusion of neuroimaging or electrophysiology measures.<b>Trial Registration:</b> Australian New Zealand Clinical Trials Registry (ACTRN12617000795392; registered 31 May 2017).
