Walnuts may contribute to brain health
The value of fruits and vegetables to prevent cardiovascular diseases and cancer has been ingrained in us.
Now, two recent studies emphasize the inclusion of a daily dose of nuts.
Walnuts, specifically.
Researchers say snacking or perking up a meal with them may improve cognitive function and prevent Alzheimer's disease.
The first study, published in the Journal of Alzheimer's Disease, was led by Dr. Abha Chauhan, a biochemist who is head of the Developmental Neuroscience Laboratory at the state Institute for Basic Research in Developmental Disabilities in Willowbrook.
The study found significant improvement in learning skills, memory, reducing anxiety and motor development in mice fed a walnut-enriched diet.
"These findings are very promising and help lay the groundwork for future human studies on walnuts and Alzheimer's disease — a disease for which there is no known cure," said Chauhan.
The research suggests that the high antioxidant content of walnuts may have been a contributing factor in protecting the mouse brain from the degeneration typically seen in Alzheimer's disease.
In addition to numerous vitamins and minerals, walnuts are the only nut that contains a significant source of alpha-linolenic acid (ALA), an omega-3 fatty acid credited with heart and brain-health benefits.
A second study out of the University of California-Los Angeles further extended the body of research. It found that study participants with higher walnut consumption performed significantly better on a series of six cognitive tests.
If you're wondering how many hours a day you are going to need to shell walnuts in order to make a difference, there is more good news: All that is needed is a handful a day.
