Dementia is a significant public health priority with ~55 million cases worldwide, and this number is predicted to quadruple by 2050. Adherence to a healthy diet and achieving optimal nutritional status are vital strategies to improve brain health. The importance of this area of research has been consolidated into the new term “nutritional psychiatry”. Dietary nitrate, closely associated with the intake of fruits and vegetables, is a compound that is increased in dietary patterns such as the Mediterranean and MIND diets, and has protective effects on cognition and brain health. Nitrate is characterised by a complex metabolism, and is the precursor of the nitrate-nitrite-nitric oxide pathway contributing to systemic NO generation. A higher intake of dietary nitrate has been linked to protective effects on vascular outcomes including blood pressure and endothelial function. However, the current evidence supporting the protective effects of dietary nitrate on brain health is less convincing. This paper aims to provide a critical appraisal of the current evidence for dietary nitrate supplementation for improving brain health, and provide suggestions for future research.
