Cognitive health and Mediterranean diet: just diet or lifestyle pattern?
Yannakoulia M, Kontogianni M, Scarmeas N.. Ageing research reviews, 2014-10-18
Topic: Risk, prevention and care in population studies
Mediterranean diet is a term used to describe the traditional eating habits of people in Crete, South Italy and other Mediterranean countries. It is a predominantly plant-based diet, with olive oil being the main type of added fat. There are many observational studies exploring the potential association between adherence to the Mediterranean diet and cognitive decline. The present review focuses on longitudinal studies with repeated cognitive assessments. It also evaluates evidence on behaviors related to the Mediterranean way of living, that have been shown to be associated with cognition, namely social interaction, participation in leisure activities, including physical activities, and sleep quality. The synergistic association-effect of these lifestyle behaviors, including diet, is unknown. Lifestyle patterns may constitute a new research and public health perspective.

How this study scored 52/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 30 of the 58 points we could judge it on, which is 52 out of 100.
