Foods That Enhance Brain Health and Memory
British nutritionist Leslie Reid recommended a range of foods that can support brain health and cognitive functions in the long term, including memory, noting that proper nutrition forms a fundamental pillar in preserving memory and concentration as people age, alongside physical activity, social interaction, and continuous mental stimulation.
Reid explained that dark leafy vegetables, such as spinach and kale, are rich in magnesium and B vitamins, playing a key role in supporting energy production within brain cells and nervous system function. She also emphasized the importance of nuts as a source of healthy fats that provide brain cells with their structure and normal function, recommending them as a regular snack instead of less beneficial options.
Other notable foods recommended by the expert to support brain health include:
- High-quality protein: Essential for building amino acids, which form the basic building blocks of body cells and neurotransmitters. Chickpeas were highlighted as a good and affordable protein source; they can be roasted, added to salads, or turned into hummus to be served with bread or vegetables.
- Blueberries and dark purple fruits: These are often absent from daily diets despite containing antioxidant compounds that support brain health.
These recommendations came following an extensive two-year Finnish study involving older adults at risk of cognitive decline. Participants were divided into two groups: the first underwent a comprehensive program including guided exercise sessions four times a week, personalized nutritional counseling to support brain health, cognitive training, regular social activities, and periodic health monitoring. The second group received only general health advice through four group sessions over the course of the study. Results showed that members of the first group performed better on tests of cognition, episodic memory, executive functions, and mental processing speed, reinforcing the hypothesis that integrated lifestyle changes, particularly nutrition, may help protect cognitive functions as people age.
Reid stressed that diversifying daily food sources, rather than relying on a single “magic” food, remains the most effective approach for supporting long-term brain health.
