What is it about?
This study aimed to identify dietary patterns (DPs) in a Chinese elderly, and assessed how they relate to cognitive decline (including global and domain-specific cognition) over 2 years. In sum, the intake of vegetable or fermented foods may be good for logical memory, but vegetable intake may not be good for brain executive function. Meat consumption may protect against attention decline while relate to verbal fluency decline.

Why is it important?
Previous studies have focused on the western diet. However, there are substantial differences in cooking style, dietary habits, food items, and nutrients in foods across geographical regions. DPs identified in western countries were inapplicable to Asians. In addition, most studies assessed “global” cognition, which did not differentiate the domain-specific effect associated with different DPs. Therefore, this study was aimed to identified DPs related to cognitive decline for Chinese elderly.
Perspectives
The identification of DPs for Chinese elders will be helpful for reducing cognitive decline. Further studies with an appropriate longitudinal design and conducted in community dwelling samples, and/or intervention design are needed to explore the efficacy of dietary habit modification in preserving or reducing cognitive decline in the elderly.
