Mediterranean-style diet may help ward off mild cognitive impairment

According to a study published in this month's issue of the Archives of Neurology, "a diet laden with fish, olive oil, veggies, and other foods common in Mediterranean-style cuisine may help ward off mild cognitive impairment, sometimes called borderline dementia." Unfortunately this is a retrospective study. We all know the difficulty of remembering past events. As one of the groups studied already had moderate dementia how reliable was their recall? While there are numerous studies that support the the Mediterranean diet we need prospective studies.
