Walnuts Fight Alzheimer’s

DIET VIDEO + ARTICLE:

Walnuts fight Alzheimer’s in a big way in the lab. Learn how walnuts appear to have a beneficial effect in reducing risk, delaying onset, slowing progression and preventing Alzheimer’s.


FOLSOM, Calif. — An important animal study published in the Journal of Alzheimer’s Disease indicates that a diet including walnuts may have a beneficial effect in reducing the risk, delaying the onset, slowing the progression of, or preventing Alzheimer’s disease.

Research led by Abha Chauhan, PhD, head of the Developmental Neuroscience Laboratory at the New York State Institute for Basic Research in Developmental Disabilities (IBR), found significant improvement in learning skills, memory, reducing anxiety, and motor development in mice fed a walnut-enriched diet.

High Antioxidant Content

The researchers suggest that the high antioxidant content of walnuts (3.7 mmol/ounce)1 may have been a contributing factor in protecting the mouse brain from the degeneration typically seen in Alzheimer’s disease. Oxidative stress and inflammation are prominent features in this disease, which affects more than five million Americans2.

Walnuts’ Protective Cognitive Effect

“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 lead researcher Dr. Abha Chauhan, PhD. “Our study adds to the growing body of research that demonstrates the protective effects of walnuts on cognitive functioning.”

One Ounce a Day Keeps Amyloid Away

The research group examined the effects of dietary supplementation on mice with 6 percent or 9 percent walnuts, which are equivalent to 1 ounce and 1.5 ounces per day, respectively, of walnuts in humans. This research stemmed from a previous cell culture study3 led by Dr. Chauhan that highlighted the protective effects of walnut extract against the oxidative damage caused by amyloid beta protein. This protein is the major component of amyloid plaques that form in the brains of those with Alzheimer’s disease.

Someone in the United States develops Alzheimer’s disease every 67 seconds, and the number of Americans with Alzheimer’s disease and other dementias are expected to rapidly escalate in coming years as the baby boom generation ages. By 2050, the number of people age 65 and older with Alzheimer’s disease may nearly triple, from five million to as many as 16 million, emphasizing the importance of determining ways to prevent, slow or stop the disease.

Other Heart & Brain Benefits

Walnuts have other nutritional benefits as they contain numerous vitamins and minerals and are the only nut that contains a significant source of alpha-linolenic acid (ALA) (2.5 grams per ounce), an omega-3 fatty acid with heart and brain-health benefits4,5. The researchers also suggest that ALA may have played a role in improving the behavioral symptoms seen in the study.
