Until now we knew walnuts as an advisable dry fruit to take care of heart health, but apparently their virtues do not stop there: scientists from the Institute for Basic Research in Developmental Disabilities in New York (United States) suggest that the extract of walnuts can offer a protective effect against oxidative stress and cell death caused by beta amyloid protein, the main component of amyloid deposits and senile plaques of people with Alzheimer's.
According to Dr. Abha Chauhan, author of the research, walnuts are a complete food rich in nutrients that not only provide antioxidants, but also alpha-linolenic acid (ALA), vegetable-derived Omega-3 fatty acids, which "offer anti-inflammatory properties and protect brain cells from oxidative damage. "
This promising breakthrough opens a new path in the search for foods that improve cognitive health
In the research it was observed how the extract of walnuts reduces cell death caused by amyloid beta proteins and cytotoxicity by decreasing the generation of free radicals, reducing the damage in the membranes and attenuating the damage in the DNA. This effect could be due to the active compounds present in the nuts, which can increase the capacity of the endogenous antioxidant defenses and can modulate the cellular state of reduction-oxidation.
This promising advance in the fight against neurodegenerative diseases, which has been published in the journal 'Neurochemical Research', opens a new path in the search for certain foods that help maintain or improve cognitive health.
