What effects has the Mediterranean diet had on stroke risk?
A randomized, controlled trial of the Mediterranean diet performed in 7447 individuals at high cardiovascular risk showed that those on an energy-unrestricted Mediterranean diet supplemented by nuts (walnuts, hazelnuts, and almonds) had a lower risk of stroke than people on a control diet (3.1 versus 5.9 strokes per 1000 person-years; P=0.003) and that those on an energy-unrestricted Mediterranean diet supplemented by extra virgin olive oil had a lower risk of stroke than people on a control diet (4.1 strokes per 1000 person-years).
