Peanuts Improve Memory by 6%: New Study for the Elderly.
According to ТСН: Regular consumption of peanuts may significantly improve memory and blood circulation in the brains of the elderly, researchers from Maastricht University believe.
Participants in the experiment who consumed 60 grams of unsalted roasted peanuts daily for 16 weeks showed a 5.8% increase in verbal memory. They found it easier to remember words from a list even after some time.
The Secret Lies in L-Arginine and Improved Blood Circulation
Scientists link the positive effects of peanuts to several factors:
L-arginine - this amino acid found in peanuts promotes improved blood flow to the brain.
Bioactive compounds - substances found in the skin of peanuts (which were consumed along with the roasted seeds) help protect brain cells.
Improved blood circulation provides the brain with more oxygen and nutrients, which are critically important for its cognitive functions.
“Adequate blood flow to the brain is important for delivering oxygen and nutrients to brain cells... Without enough oxygen and nutrients, the highly metabolically active brain cannot function properly, and key functions such as memory may be impaired,” explained Peter J. Joris from Maastricht University.
Objective Indicators of Improvement
The study conducted using MRI confirmed physiological changes. Global cerebral blood flow increased by 3.6%, while blood flow in the gray matter rose by 4.5%. In important areas responsible for memory and language (frontal and temporal lobes), blood flow increased by 6.6% and 4.9%, respectively.
The experiment involved 31 healthy individuals aged 65 to 75. Despite consuming an additional 340 calories daily from peanuts, the participants' weight remained unchanged as they adjusted their intake of other foods accordingly.
Scientists emphasize that to achieve this effect, unsalted peanuts roasted with skin should be consumed, as the skin contains many antioxidants and fiber.
It is worth mentioning that superfoods have been marketed for years as “magical” products with exceptionally high nutrient content that supposedly cleanse the skin, slow down aging, and improve overall well-being. However, experts note that most of these “superfoods” are overrated, and their effect can be easily achieved through a varied diet.
Furthermore, scientists found that limiting calorie intake by 30% over an extended period can slow down brain aging and prevent cognitive decline.
This study highlights the importance of including peanuts in the diet to support brain health in the elderly. The results may serve as a basis for further research to determine the role of nutrition in maintaining cognitive functions with age.
