Processed meats and sugary drinks linked to cognitive decline

Eating processed meats and sugary drinks may harm brain health over time, a new study finds.

Why it matters

  • Dietary choices may impact cognitive health in older adults.
  • Processed meats and sugary beverages are common in many diets.

By the numbers

  • 7-year study of U.S. residents aged 55+.
  • 17% increase in cognitive issues for those consuming one serving of processed meat daily.
  • 6% increase in cognitive impairment per serving of soda.

The big picture

  • Ultra-processed foods are known to harm health, but this study highlights specific categories affecting brain health.
  • Simple dietary changes could help maintain cognitive function as you age.

What they're saying

  • Experts suggest reading labels, cooking at home, and choosing healthier options like water over soda.
  • The study’s findings are a wake-up call for those looking to keep their brain sharp.

Caveats

  • Observational study; cannot establish causality.
  • Self-reported dietary data may be unreliable.

What’s next

  • Researchers plan to study young adults and ultra-processed foods.
  • Future work includes teaching cooking skills to evaluate their impact on brain function.
