Eating more fruit may decrease your risk of suffering a dangerous vascular condition, according to new research in the American Heart Association journal Circulation.
In a Swedish study, people who reported eating more than two servings of fruit daily had a lower risk of abdominal aortic aneurysm than those who ate the least amount of fruit.
Abdominal aortic aneurysm is a ballooning of the lower part of the aorta, the main blood vessel that supplies the body. It’s relatively rare, but can be lethal. Older men, especially those who have smoked, are at higher risk.
Ultrasound screening, which uses sound waves to image structures in the body, can easily detect the condition.
Researchers divided more than 80,000 people, ages 46-84, into four equal-size groups based on how much fruit and vegetables they reported eating.
In the next 13 years, hospital and death records showed 1,086 people had abdominal aortic aneurysms, including 222 whose aneurysms ruptured. More than 80 percent of the aneurysms and ruptures were in men.
Researchers found:
* Compared to those eating the least amount of fruit (less than one full serving), those who ate the most (more than two servings daily, not counting juice) had a 25 percent lower risk of the aortic condition and 43 percent lower risk of a ruptured aneurysm.
*Compared to those who didn’t eat any fruit, those who had two servings a day had a 31 percent lower risk of a nonruptured aneurysm and a 39 percent lower risk of a ruptured aneurysm.
“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,” said Otto Stackelberg, M.D., lead author and a Ph.D. student at the Institute of Environmental Medicine’s Nutritional Epidemiology Unit at Karolinska Institutet in Stockholm.
High levels of antioxidants in fruits might protect against abdominal aortic aneurysm by preventing oxidative stress that can promote inflammation.
Researchers found no association for vegetables, which are also rich in antioxidants. Vegetables lack some types of antioxidants that are in fruits, which might help explain the fruit versus vegetable findings, Stackelberg said.
“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,” Stackelberg said.
In the study, people ate apples and pears the most, followed by bananas, oranges and other citrus fruits.
