Fruits and vegetables preserve cognition in mice fed a Western-style diet

BLUF

Adding enough fruits and vegetables helped protect memory in mice eating a high-fat diet, suggesting food quality can buffer the brain against obesity-related cognitive decline, even when weight gain is not fully prevented.

Learning Outcomes

• Understand how diet quality can influence cognitive performance under metabolic stress.
• Recognise oxidative stress as a link between nutrition and brain health.
• Apply evidence on nutrition to support long-term cognitive resilience in demanding roles.
