小紅莓可預防動脈硬化

在日常的水果當中,偶爾會吃到小紅莓,只知道這種水果吃起來口感還不錯,至於他對健康有甚麼幫助,倒是沒有特別去注意。

最近看到醫學期刊報導「小紅莓可預防動脈硬化」,讓我好奇的看下去。

這是美國著名的Mayo Clinic 所發表的研究報告,他們發現實驗組每天喝兩杯小紅莓果汁,連續四個月之後,血液中一種導致動脈硬化的物質osteocalcin 和 endothelial progenitor cells 都顯著下降,表示小紅莓可以預防動脈硬化。

小紅莓含有豐富的聚合前花青素 proanthocyanadins,聚合前花青素是一種植物營養素,歸類為植物中的多酚類,具有很高的活性,且無毒性,它的抗氧化能力是同劑量維生素C的20倍,維生素E的50倍。

估計就是這種抗氧化能力達成預防動脈硬化的效果。有興趣的人可參看下面的原文:

Cranberries Help to Protect Artery Health
Posted on 2012-03-27 06:00:01 in Cardio-Vascular | Functional Foods |

Cranberries are rich in proanthocyanadins, compounds with potent antioxidant activity.  Amir Lerman, from the Mayo Clinic (Minnesota, USA), and colleagues enrolled 54 men and women, average age 49.5 years, randomly assigning each to either receive two glasses of cranberry juice a day for four months, or a placebo drink. The team utilized an imaging technique to analyze changes in the blood vessels, and took blood samples to assess for levels of endothelial progenitor cells and osteocalcin, markers that are associated with arterial hardening.  Among the study subjects who drank the cranberry juice, the expression of osteocalcin by endothelial progenitor cells was greatly reduced, as compared to the placebo group, leading the study authors to conclude that: “the decrease in the fraction of osteocalcin+ [endothelial progenitor cells]  suggests a potential beneficial effect of polyphenol-rich [cranberry juice].”
