吃苹果对心脏健康大有好处

Taking apples daily is one way of keeping risks linked with cardio health at bay.

导读：每天坚持吃苹果不失为一种抵御心脏健康风险的好方法

Catherine Bondonno, doctoral student in pharmacology at the University of Western Australia, researched the effect of apples on nitric oxide (NO) production and endothelial function, which affect cardiovascular health.

西澳洲大学（University of Western Australia）的医药学博士研究生Catherine Bondonno，就苹果对影响心血管健康的一氧化氮（NO）的产生及内皮功能的效应进行了研究。

"The endothelium is a single layer of cells lining blood vessels and produces nitric oxide," says Bondonno.

Bondonno 表示，“内皮组织是血管内壁上的一层细胞，可以产生一氧化氮”

Flavonoids, collectively known as Vitamin P and cirtrin, concentrate in the skin of apples, which also give fruits their distinctive flavours.

"Nitric oxide signals the surrounding muscles to relax, which causes the blood vessel to dilate increasing blood flow through the vessel," a Western Australia statement quoted her as saying.

Bondonno selected a group of healthy volunteers, who after undergoing a battery of tests, were randomly assigned to consume either the apple with skin first followed by the flesh only, or vice versa.

On the study day, an apple was eaten with breakfast and again with lunch to account for the varying times the flavonoids peak in the blood stream.

Results indicated that flavonoid rich apples improve nitric oxide status and endothelial functions, factors affecting cardiovascular health.

研究结果表明：富含黄酮类物质的苹果可以改善一氧化氮状况及内皮功能，而这两个因素则会影响心血管健康。
