Food fuels the body, but research is increasingly showing that it also supports the brain. A new one Special Collection on Food and the Brain in ASN Food magazine brings together research from the growing field of nutritional cognitive neuroscience. In Opening editor-in-chief, guest editor Aron K. Barbey, Ph.D. introduces the collection and explains why nutrition is important to understanding brain health.
Mental health and neurological problems are increasing worldwide. At the same time, research shows that nutrition plays an important role in brain function throughout life. Food provides more than energy. It supports systems related to memory, mood, learning and overall brain health.
Nutritional cognitive neuroscience looks at brain health through four related aspects of the human experience:
- Environmental factors affecting risk and access to healthy food
- Psychological factors that influence and affect food choices
- Biological factors affecting brain processing and nutrient utilization
- Lifestyle factors such as exercise, sleep and daily habits that shape eating patterns
Together, these dimensions explain why nutrition can affect people differently and how diet can support brain flexibility, resilience, and mental well-being over time.
This Special Collection on Nutrition and the Brain brings together research spanning the genetic, molecular, cellular, and systems levels. Together, 14 research articles and 3 reviews examine how nutrition affects the brain at different stages of life and areas of health. Highlights from the collection include:
- Maternal nutrition and brain development: Several studies examine how a mother’s diet during pregnancy can shape brain development and behavior later in life. For example, research shows that imbalances in certain fats during pregnancy can affect the learning, social behavior and memory of offspring in adulthood.
- Specific Nutrients and Brain Health: Some research looks at individual nutrients and foods, such as antioxidant-rich foods and vitamin K, and how they can help reduce brain inflammation, protect memory, and support learning.
- The gut-brain connection: A growing body of research shows how what we eat affects gut bacteria, which can affect brain development. The reported findings suggest that a number of dietary components and nutritional interventions may play an important role in regulating metabolic and inflammatory pathways that influence cognitive function and brain health.
- When we eat, not only what we eat: The collection also includes research on eating patterns and timing. One study found that adults who ate frequently performed better on tests of memory, language, and executive function, suggesting that the timing and regularity of meals may play a role in cognitive health.
- Personal nutrition: Other studies look at large populations to show that genetic differences can affect how the brain reacts to nutrients like omega-3 fatty acids. These findings suggest that individualized dietary approaches should take into account individual genetic differences.
- Risk of aging and dementia: Several articles examine diet, including elements of the MIND diet, to better understand how diet can reduce the risk of dementia and support healthy brain aging.
- Mental health and infectious diseases: Some of the research in the collection examines how what we eat affects brain health and inflammation in people with conditions such as depression or HIV.
- Nutrition in mental health education: Some studies indicate that nutrition is often overlooked in psychiatry. More than two-thirds of psychiatrists and psychologists report having no formal guidelines on nutrition, and very few discuss nutrition when treating patients. These findings point to the need for broader public health efforts to raise awareness of the importance of diet and nutrition in mental health.
