Beetroot juice could help people live more active lives
Date:12/17/2010

ffects have a significant impact on performing physical tasks, whether it involves low-intensity or high-intensity effort.

So far the research on the impacts of beetroot juice has only been carried out on younger people who are in good health, but the researchers believe there is no reason why the effects of beetroot juice wouldn't help others.

"While we haven't yet measured the effects on the elderly or those with heart or lung conditions, there is the potential for a positive impact in these populations which we intend to go on and investigate further," Katie Lansley added.

Beetroot juice contains high levels of nitrate. The latest study has proved that this is the key ingredient which causes the increase in performance, rather than any other component of the beetroot juice.

Professor Andy Jones, the senior scientist on the study and a pioneer of research into beetroot juice, said: "In this study, we were able to use - for the first time - both normal beetroot juice and beetroot juice with the nitrate filtered out. Test subjects didn't know which one they were getting. The drinks both looked and tasted exactly the same. Each time the normal, nitrate-rich juice was used, we saw a marked improvement in performance which wasn't there with the filtered juice so we know the nitrate is the active ingredient."
