Lots of fruit & veges helps older brains

Data from the Canadian Longitudinal Study on Aging, involving 8,574 middle-aged and older adults (aged 45-85), has found that those who ate more vegetables and fruits and more nuts and pulses (such as lentils and beans) scored higher on tests of verbal fluency. Every increase in average daily fruit and vegetable intake was linked to higher verbal fluency scores, but the best outcomes were found among those who consumed at least 6 servings a day.

Additionally, those with stage 2 hypertension had lower verbal fluency scores, as did those with higher levels of body fat.
