Grape and Berry Juices: Elixirs for Long Life? AND a word to the wise
In the first comprehensive study of the antioxidant content of various juices, published in the Journal of Agriculture and Food Chemistry, researchers at the University of Glasgow examined 13 different brands of fruit juices from a local U.K. supermarket.
They measured the number as well as the levels of antioxidants in apple, orange, grapefruit, cranberry, pineapple, tomato and grape juice, and found that purple grape juice has the highest concentration of antioxidants among juices. In fact, the more popular orange juice or clear apple juice have the lowest antioxidant content.
The recent U.S.-based Kame project suggested that volunteers who drank three or more glasses of juice a week could reduce the risk of Alzheimer's by 76 percent, compared with those who drank juice less than once a week.
But some scientists, like Bridget Aisbitt, a nutrition scientist at the British Nutrition Foundation, counsel caution about the antioxidant phenomenon. According to Aisbitt "These days, 'antioxidant' has become such an over-hyped buzzword, it's used on everything from shampoo to food. People should be careful about jumping onto the bandwagon".
A word to the wise: The study was funded by the National Grape Co-operative, a consortium of U.S. farmers which is owned by Welch's, the makers of Concord purple grape juice.
