上周去买菜的时候，在organic products架子那里看到了一些饮料，仔细看了看说明，说是含有一种叫pomegranate的冬冬，抗氧化，也就是抗衰老阿，于是就买了两瓶回来，还跟connect吹了吹。connect还说就是维生素C。今天一查才知道原来就是石榴阿。真本，不过，除了含有很高的VC外，还是含有很多抗氧化物质的，不知道管不管用。

Pomegranate -- Health benefits

One pomegranate delivers 40% of an adult's daily vitamin C requirement. It is also a rich source of folic acid and of antioxidants. Pomegranates are high in polyphenols. The most abundant polyphenols in pomegranate are hydrolysable tannins, particularly punicalagins, which have been shown in many peer-reviewed research publications to be the antioxidant responsible for the free-radical scavenging ability of pomegranate juice.

Many food and dietary supplement makers have found the advantages of using pomegranate extracts (which have no sugar, calories, or additives), instead of the juice, as healthy ingredients in their products. Many pomegranate extracts are essentially ellagic acid, which is largely a by-product of the juice extraction process. Ellagic acid has only been shown in published studies to absorb into the body when consumed as ellagitannins such as punicalagins.^[7]

In several human clinical trials, the juice of the pomegranate has been found effective in reducing several heart risk factors, including LDL oxidation, macrophage oxidative status, and foam cell formation, all of which are steps in atherosclerosis and heart disease. Tannins have been identified as the primary components responsible for the reduction of oxidative states which lead to these risk factors.[2] Pomegranate has been shown to reduce systolic blood pressure by inhibiting serum angiotension converting enzyme (ACE).^[8]

Research suggests that pomegranate juice may be effective against prostate cancer^[9][10] and osteoarthritis.^[11]
