Current demographic trends indicate that the population is aging. The aging process is inevitably connected with cognitive decline, which manifests itself in worsening working memory, processing speed, and attention. Therefore, apart from pharmacological therapies, non-pharmacological approaches which can influence cognitive performance (such as physical activities or healthy diet), are being investigated. The purpose of this study is to explore the types of nutritional interventions and their benefits in the prevention and delay of cognitive delay in healthy older individuals. The methods used in this study include a literature review of the available studies on the research topic found in Web of Science, Scopus, and MEDLINE. The findings show that nutritional intervention has a positive impact on cognitive function in healthy older people. However, it seems that the interactions between more than one nutrient are most effective. The results reveal that specifically the Mediterranean diet appears to be effective in this respect. Moreover, the findings also indicate that multi-domain interventions including diet, exercise, cognitive training, and vascular risk monitoring have a far more significant effect on the enhancement of cognitive functions among healthy older individuals.
