What Does Ultra-Processed Food Do to Your Brain? Scientists Found a Pattern

Summary

A new review of scientific research found that eating a lot of ultra-processed foods may harm brain health, especially as people get older. These foods, often high in sugar and unhealthy fats, might increase the risk of memory problems and dementia.

Key Facts

  • Ultra-processed foods (UPFs) are industrially made and often include artificial ingredients not usually found in home cooking.
  • Examples of UPFs are packaged snacks, sugary drinks, instant meals, processed meats, and some breakfast cereals.
  • People who eat more UPFs tend to perform worse on memory and thinking tests.
  • UPFs are linked to health issues like obesity, Type 2 diabetes, and heart disease, which also raise dementia risk.
  • UPFs may cause low-level inflammation in the body, which could harm the brain over time.
  • The gut microbiome, which affects brain health, may be disrupted by highly processed diets.
  • Not all processed foods are unhealthy; minimally processed options like frozen vegetables and canned beans can be good.
  • Experts recommend eating more fruits, vegetables, nuts, whole grains, and other minimally processed foods to protect brain health.
