Mediterranean-style diet and cognition

Diet is one lever for brain health. Mediterranean-style eating patterns are among the most studied and consistently promising.

What the pattern looks like

• Plenty of vegetables, fruit, and whole grains.
• Beans, nuts, fish, and olive oil.
• Less processed food, red meat, and added sugar.

What research suggests

• Linked with slower cognitive decline in many studies.
• Part of overall cardiovascular health.
• Effects are modest but meaningful across a population.

Everyday steps

• Add an extra portion of vegetables to meals.
• Swap refined grains for whole grains.
• Use healthy fats like olive oil.

What it means for everyday practice

Evidence points to a few practical habits rather than any single “cure”:

• Favour approaches that are consistent, meaningful, and sustainable.
• Track what helps you - responses vary from person to person.
• Combine professional therapy with regular home practice.
