Eating our daily quota of fruits and vegetables should be a no-brainer by now, as we have long heard of the health benefits accompanying a balanced diet. And now researchers in Sweden have discovered that eating more fruit could lower risks for an often-lethal form of aortic aneurysm.
The researchers, led by Dr. Otto Stackelberg of the Karolinska Institute, published their findings in the American Heart Association’s journal Circulation.
After dividing over 80,000 people between the ages of 46 and 84 years into four groups based on the amount of fruit and vegetable they ate each day, the researchers then embarked on a 13-year follow-up study. During that time, they found that 1,086 people had abdominal aortic aneurysms, 222 of which ruptured.
This type of aortic aneurysm involves a swelling of the lower part of the aorta, the body’s main artery. Though rare, the researchers note, it is lethal in many cases. Men in the study accounted for over 80% of aneurysms, ruptured aneurysms included.
Compared with the group who ate the least amount of fruit (less than one daily serving), those who ate the most fruit (over two servings) had a 25% lower risk of developing an aneurysm and a 43% lower risk of one that ruptured.
Fruit juice did not count towards servings in the study.
Additionally, compared with the group who did not eat any fruit at all, the high fruit-eaters had a 31% lower risk of an aneurysm and a 39% lower risk of a ruptured one.
The types of fruits the subjects ate were mainly apples and pears, followed by bananas, oranges and other fruits of the citrus variety.
The researchers say that abdominal aortic aneurysm is often asymptomatic and occurs in up to 4.5% of men over 65 years of age. In women of the same age group, up to 1.3% are affected.
Though ultrasounds have been used for screening the condition, they say these abdominal aneurysms are highly likely to be lethal, citing a mortality risk of 70% before surgery and 35% after.
Dr. Otto Stackelberg is happy with the results of the study, adding:
“A high consumption of fruits may help to prevent many vascular diseases, and our study suggests that a lower risk of abdominal aortic aneurysm will be among the benefits.”
Vegetables – also high in antioxidants – did not seem to affect the risk level for abdominal aortic aneurysm, possibly because some vegetables lack fruit antioxidants, say the researchers.
Dr. Stackelberg adds: “Vegetables remain important for health. Other studies have found that eating more fruits and vegetables may decrease the risk of cardiovascular diseases, type 2 diabetes, high blood pressure, and several cancers.”

And of course, not smoking is a major way to reduce health risks, especially those involved with cardiovascular health. Dr. Otto Stackelberg says:
“Being a non-smoker is also crucial in preventing abdominal aortic aneurysm. Never start smoking; and if you already do smoke, quit today. It’s never too late.”
