Use of grapes twice daily may provide protection against senile dementia. That is the conclusion reached by experts in the field of healthy nutrition from the University of California in Los Angeles.
US scientists have proved that eating grapes twice a day for a total of 6 months, the brain provides protection against pathological processes associated with the development of Alzheimer's disease. Results of the study showed that a diet containing grapes protects from reduced metabolic activity, which is essential for cognitive processes and the normal functioning of working memory.
Eat grapes people demonstrated increased metabolism in other brain regions.
The researchers studied the effects of a proper grape whole and its individual components on brain function. These data suggest that grape provides a protective effect against senile dementia. The results of this study have become another argument to support the theory that the grapes are useful for neurological and cardiovascular health. However, to confirm these findings require more extensive study.
In the current experiment, the researchers selected volunteers, demonstrating an early decline in mental performance. All of them received a grape extract, which corresponds to two and a half cups of berries, or does not contain polyphenol extract placebo, absolutely similar in taste and appearance. After 6 months, volunteers have gone through an independent assessment of their cognitive activity. Changes in brain metabolism were evaluated by positron emission tomography.
It turns out that the grapes helps maintain a healthy metabolic activity in those areas of the brain, which previously often seen the development of senile dementia.
