A new study conducted in Great Britain reveals that a simple and inexpensive dietary supplement can have surprisingly positive effects on the brains of older people.
TL;DR
- Daily intake of prebiotic fiber supplements (inulin or FOS) improved memory test results in people over 60.
- The study observed an increase in Bifidobacterium in the gut microbiota, linked to better cognitive function.
- The supplements are cheap, widely available, and safe, making them accessible.
- The effects were noted after three months in a double-blind study using twins.
- Further research will examine long-term effects and larger participant groups.
