Abstract


Background: Stroke is a leading cause of death. Current therapeutic strategies have been unsuccessful. Several studies have reported benefits on reducing stroke risk and improving the poststroke associated functional declines in patients who ate foods rich in fruits and vegetables. Their potential protective effects may be due to their antioxidants, calcium, potassium, riboflavine, peridoxin, riboflavin contents. Folic acid, peridoxin, and riboflavin are all cofactors in hyperhomocysteinemia as a stroke risk factor. Studies suggest that oxidative stress plays important roles in pathogenesis of ischemic cerebral injury and higher intake of antioxidants has been associated with a lower stroke risk. The aim of this study was to examine if the dietary intake of vegetables and fruits in patients with stroke were comparatively worse than those in patients without stroke.

Methods: In this case control study,93 stroke patients admitted to Alzahra hospital were matched for age and sex with 60 patients who were not affected with acute cerebrovascular diseases and did not have a history of stroke. Dietary intake was assessed with a validated food frequency questionnaire.Food intakes were compared between two groups and with recommended value.

Results: Mean daily intake of vegetable and fruits was more in male with stroke than male without stroke as well as calorie intake from vegetables and fruit was higher in male with stroke.Mean daily intake of vegetable and fruits were lower in women with stroke than women without stroke as well as calorie intake from vegetables and fruit was lower in women with stroke

Conclusions: Our findings suggest that increased vegetable and fruits intake may be associated with decreased risk of stroke

Keywords: Dietary quality, fruit, stroke, vegetable
