Eating This May Lower Dementia Risk: Fiber Linked to Better Brain Health

Recent research highlights that dietary fiber—found in vegetables, fruits, whole grains, beans, and nuts—may help lower dementia risk by improving gut health and influencing the gut-brain axis. Studies report that people who consume more fiber tend to show lower dementia incidence and better memory or cognitive test scores in older adults. When gut bacteria break down fiber, they produce short-chain fatty acids like butyrate, which help protect the intestinal lining and reduce inflammation; lowered inflammation may indirectly benefit brain health. Experts caution that current evidence shows association, not direct causation, and fiber should be part of an overall healthy lifestyle including balanced diet, exercise, and sleep. Practical tips include choosing brown rice (현미) instead of white rice and snacking on fruit or nuts instead of chips to reach the recommended 25–30 g of fiber per day.
