Abstract
Background: Currently, there is a significant increase in the number of older generation groups, which may result in serious economic and social issues. Therefore, there is a need to prolong the active life of these older individuals, especially by focusing on modifying lifestyle factors such as healthy nutrition.
In fact, recent research has shown that, for example, nuts are an important part of people's healthy diet because they have appeared to be neuroprotective compounds which might maintain or in some cases even improve people's cognitive functions. Objective: The purpose of this review study is to explore the role of the nut nutrition in the maintenance and delay of cognitive decline among older individuals.
Results: The findings indicate that the nut consumption may contribute to the delay of cognitive decline in aging. However, this nut diet is just one component of the multi-nutrient dietary intervention for health aging.
Conclusion: More longitudinal controlled randomized studies have to be performed in this field to prove the efficacy of the nut nutrition for the delay of cognitive decline.
