HealthDay News — Ten daily servings of fruits and vegetables may be a key to reducing the risk of myocardial infarction, stroke, cancer, and premature death, according to a review published online Feb. 22 in the International Journal of Epidemiology.
Together, the 95 studies the Imperial College London scientists analyzed included almost 2 million people. The benefits of high fruit and vegetable consumption appear to come through lower rates of myocardial infarction, stroke, cancer, and early death. And if everyone found a way to get 10 daily servings of produce, 7.8 million premature deaths would be avoided each year worldwide, the researchers estimated.
Even just over 2 portions a day made a difference in the review, the researchers added. Eating 2.5 portions (200 grams) of produce on a daily basis was associated with reductions in coronary heart disease (by 16%); stroke (18%); cardiovascular disease (13%); cancer risk (4%); and premature death (15%).
The results for 10 daily servings were even stronger: a 24% reduced risk of coronary heart disease; a 33% reduced risk of stroke; a 28% reduced risk of cardiovascular disease; a 13% reduced risk of cancer; and a 31% reduction in premature death risk.
In their review, the researchers also found signs that the following types of produce seemed to confer the greatest benefits: apples, pears, citrus fruits, green leafy vegetables, cruciferous vegetables (such as broccoli, cabbage, and cauliflower), and green and yellow vegetables (such as green beans, spinach, carrots, and peppers).
