Goji juice: the ultimate anti-oxidant food
There have been some ridiculous claims made about wolfberries, such as eating them can prevent 75% of all known cancers. This kind of hyperbole has given them a bad rap. However, this is one powerful anti-oxidant. The oxygen radical absorption capacity (ORAC) of blueberries is 2,400. For the wolfberry it is a whopping 25,000.
Wolfberries are mostly cultivated in China (although the British grow it as a hedge plant called Duke of Argyll's Tea Tree) and the easiest way to consume them is as juice. Commercially, wolfberry juice is known as Goji juice.
They are rich in, according to Wikipedia, calcium, potassium, iron, zinc, selenium, Vitamin B and Vitamin C. However, the same entry is at pains to point out that any trials establishing wolfberries as an effective anti-oxidant have taken place in China and have not been verified in the west.
