Story summary
- A study of over 21,000 adults aged 40–70 links pro-inflammatory diets to accelerated brain aging.
- The brain age gap was nearly one year for those on pro-inflammatory versus anti-inflammatory diets.
- The study, published in the European Journal of Epidemiology, suggests systemic inflammation may mediate the effect.
- It notes limitations, including lack of diversity in the UK Biobank sample, and calls for future research on reversibility.
