Fruits, vegetables could cut stroke risk
Washington: Researchers have said that eating more fruits and vegetables may reduce the risk of stroke worldwide.
Researchers conducted a meta-analysis of 20 studies published over the last 19 years to assess the effects of fruit and vegetable consumption on risk of stroke globally. The combined studies involved 760,629 men and women who had 16,981 strokes.
Stroke risk decreased by 32 percent with every 200 grams of fruit consumed each day and 11 percent with every 200 grams of vegetables consumed each day.
Yan Qu, M.D., the study's senior author, director of the intensive care unit at Qingdao Municipal Hospital and professor at the Medical College of Qingdao University in Qingdao, China, said improving diet and lifestyle is critical for heart and stroke risk reduction in the general population.
Qu said in particular, a diet rich in fruits and vegetables is highly recommended because it meets micronutrient and macronutrient and fiber requirements without adding substantially to overall energy requirements.
Macronutrients (carbohydrates, protein and fat) provide calories or energy. Our bodies need smaller amounts of micronutrients such as vitamins and minerals.
The researcher cited studies demonstrating that high fruit and vegetable consumption can lower blood pressure and improve microvascular function. It has favorable effects on body mass index, waist circumference, cholesterol, inflammation and oxidative stress.
The beneficial effects of fruits and vegetables applied consistently to men and women, stroke outcome and by type of stroke (caused by clot or bleeding). Researchers found no significant difference in the effect on age (younger or older than 55).
The study has been published in the American Heart Association's journal Stroke.
