text_1: Mediterranean diet may help prevent dementia, study says
text_2: "This is a story about a study that won’t be presented for two months yet – about a health benefit that is seen in individuals who self-report consuming a Mediterranean diet. It was good that the story pointed out ""The study shows association, not causation"" but the explanation of this was a bit awkward and incomplete. It also never answered what ""36% less likely to have areas of brain damage"" really meant. 36% of what? And what clinical significance might that have? There can be a difference between being able to find something and whether that something has significance in people’s lives. Dementia is a major concern for older people. However, the gist of the story  – that the ""Mediterranean diet may help prevent dementia"" – as the headline states – is something an observational study can’t prove. That’s what the story could have better explained."
