Researchers find grape juice most beneficial among fruit juices
Scientists have found that grape juice is more beneficial than any other fruit juice for the health as it contains most polyphenols which are strong antioxidants.
British scientists had the findings when carrying out the first scientific analysis of fruit juices to measure their antioxidant activity - the anti-ageing compounds that protect against heart disease and other chronic conditions, according to a press release issued by the University of Glasgow on Thursday.
Purple grape juice is on the top list, followed by apple juice and cranberry juice, while orange juice, the most popular fruit juice, comes way down the list, according to the study by researchers at the University of Glasgow.
"The findings reveal that the variety of phenolic compounds and antioxidant capacity of the individual juices varied markedly," Alan Crozier who led the study said.
Purple grape juice made with Concord grapes contains the highest and broadest range of polyphenols as well as having the highest antioxidant capacity, and other high-ranking products include cloudy apple juice and cranberry juice drink, the research results show.
Crozier said supplementing a healthy diet with a regular mixed intake of fruit juices such as purple grape juice, grapefruit juice, cloudy apple juice and cranberry juice during the week, will increase the consumer's intake of phenolic antioxidants.
Antioxidants are compounds such as vitamin C found in fruits and vegetables which are believed to play a key role by protecting the body from the damaging effects of free radicals, the products of metabolism. By quenching free radicals they help to maintain oxidative balance and prevent the development of diseases including cancer and heart disease.
The findings also revealed the number and level of antioxidant phenolic compounds in purple grape juice equates with those found in a Beaujolais red wine.
