Eating Fruit May Reduce Risk of Abdominal Aortic Aneurysm
(HealthDay News) – Consumption of fruit, but not vegetables, may reduce the risk of abdominal aortic aneurysm (AAA), particularly ruptured AAA, according to research published in the Aug. 20 issue of Circulation.
Otto Stackelberg, MD, of the Karolinska Institutet in Stockholm, and colleagues used data from food-frequency questionnaires from 44,317 men in the Cohort of Swedish Men and 36,109 women in the Swedish Mammography Cohort, aged 46–84 years at the start of 13 years of follow-up, to assess the association of fruit and vegetable consumption with risk of developing AAA.
The researchers found 1,086 primary cases of AAA, including 222 cases of ruptured AAA. Individuals in the highest quartile of fruit consumption (>2 servings per day) had a 25% lower risk of AAA, and a 43% lower risk of ruptured AAA, than those in the lowest quartile (<0.7 servings per day). Compared with those who ate no fruit, individuals who ate two fruits per day had a 31% lower risk of non-ruptured AAA and a 39% lower risk of ruptured AAA. Eating vegetables was not linked with reduced risk of AAA.
"In conclusion, these results showed that a consumption of fruit, but not vegetables, was associated with a decreased risk of AAA, and that this reduction in risk was even more pronounced for the risk of ruptured AAA," the authors write.
