To examine the effect of fruit and vegetable intake on risk of stroke among middle-aged men over 20 years of follow-up.At baseline,the mean(+/- SD)number of fruit and vegetable servings per day was 5.1(+/-2.8).During follow-up there were 97 incident strokes,including 73 completed strokes and 24 transient ischemic attacks.Age-adjusted risk of stroke decreased across increasing quintile of servings per day(log rank P for trend,.01). Age-adjusted RR for all stroke,including transient ischemic attack,was 0. 78(95%confidence interval[CI],0.62 to 0.98)for each increase of three servings per day.For completed stroke the RR was 0.74(95%CI,0.57 to 0.96); for completed stroke of ischemic origin the RR was 0.76(95%CI,0.57 to 1. 02);and for completed stroke of hemorrhagic origin,0.49(95%CI,0.25 to 0. 95).Adjustment for body mass index,cigarette smoking,glucose intolerance, physical activity,blood pressure,serum cholesterol,and intake of energy, ethanol,and fat did not materially change the results.Intake of fruits and vegetables may protect against development of stroke in men. |
