Natural Health News – Including a glass of grape juice in the daily diet can improve memory and performance brain in particular for those who lead a stressful life as working mothers, suggests a new study.
Previous studies have identified compounds rich in polyphenols have benefits on brain function in older people. But this new study, University of Leeds in the UK, is the first to show that the cognitive benefits of drinking grape juice can be extended to other age groups as well – in this case, healthy, 40-50 age working women with pre -teen children.
Women were divided into two groups. One drank 355ml of grape juice daily Concord while the other drank the placebo (a, sugary drink grape flavored) What need to know
“ The results of two new studies published – before publication – suggest that the antioxidant polyphenols in grape juice have benefits for the mind and body
“ In the first stressed mothers who consume a glass of grape juice a day experienced a boost in memory and brain function.
“ In the second, a laboratory study, grape juice 100% was shown to slow the absorption of sugars intestinal cells, suggesting that it could have a role play in improving the blood sugar balance.
The fight against the effects of stress
Over 12 weeks, women were asked to undergo a series of tests that assessed their cognitive performance. One test was a driving simulator challenge 25 minutes in which they were asked to match the speed and direction of a lead vehicle.
Women who drank the grape juice showed significant improvements in the immediate spatial memory and driving performance compared to those who drank the placebo.
In addition, there was evidence of a long-term effect of the grape juice that allowed participants to consistently maintain better performance, even when participants stopped drinking grape juice.
Although the study was funded by Welch – producers of grape juice drinks – results, presented at the recent biennial International Conference on Polyphenols and Health (ICPH) in Dijon France, add to a growing body of evidence for the benefits of grape juice, and in particular the effects on the brain-boosting polyphenols.
Benefits blood sugar too
A second study presented at the ICPH suggested that polyphenols in grape juice (specifically Concord and Niagara grapes) may be able to help balance the glycemic response of the body by decreasing absorption of these sugars.
Researchers at the Department of Food Science at Purdue University, suggested that after drinking grape juice, sugar levels in the blood may increase less drastic than expected, which could help in control of blood glucose as part of a daily health regimen.
This laboratory study using human intestinal cells, it was found that polyphenols naturally present in the grape juice were able to slow the absorption of naturally occurring sugars present in the juice. Compared to a sweetened liquid sugar control, 100% grape juice may result in a slightly lower glycemic response, which scientists say can contribute to the long-term health.
