"Fiber Supplements: A Potential Key to Dementia Prevention and Brain Health"
A study published in the journal Nature suggests that a dietary supplement containing inulin and fructooligosaccharide (FOS), considered prebiotics, may improve brain function in people over 60. The supplement showed no improvements in muscle strength but resulted in better performance in memory, reaction time, and processing speed tests, including the Paired Associates Learning test, which can indicate early signs of Alzheimer's disease. Researchers believe that nourishing the gut microbiome with these plant fibers could support better brain function in older individuals, potentially offering long-term benefits. Additionally, Alzheimer’s Research UK reports that addressing certain risk factors in daily life could prevent or delay up to 40% of dementia cases globally.
