Eating Nuts Preserves The Brain’s Cognitive Functions, Study Says

Cognitive decline is an inevitable mental condition that comes with aging. It is also one of the hallmarks of an incurable disease called dementia. In the absence of a cure, a recent study revealed that consuming nuts preserves the brain’s cognitive functions.

As per Science Direct, diet was suggested to have a role in significantly preserving the brain’s cognitive functions as a person ages. The study ruled that the consumption of food items that are rich in n-3 (polyunsaturated) fatty acids with antioxidants and anti-inflammatory agents is a promising dietary approach that preserves the brain’s cognitive functions.

Additionally, an article published in the Royal Society of Chemistry claimed that nuts are rich in polyphenols that reduce the risk of stroke and improves endothelial-dependent blood flow and pressure that are associated with brain function.

An observational study conducted in China was published in the Journal of Nutrition Health and Aging claiming that nuts help preserve brain functions when consumed regularly.

The study analyzed 4,822 adults aged 55 years old and above and how their consumption of nuts affected their cognitive decline. Sixty-seven percent of the participants were tested for their cognitive abilities during the study while 16 percent were tested more than twice.

The researchers found that those who ate less than 10 grams or six to seven nuts per day were most likely to experience a cognitive decline compared to those who do. They also claimed that the results showed at least two teaspoons of nuts per day may preserve the brain’s cognitive functions. Unfortunately, the results were inconclusive as to the effects of the consumption of nuts to improve cognitive performance.

According to Popular Science, general health, exercise, education and nutrition intake were also considered as factors that affect cognitive decline. Although the study’s comparison of those who consumed nuts from those who did not show significant differences, the same was not conclusive as to whether the ingredient was the only one that countered cognitive decline.

The report also highlighted the weakness of the study. The randomized controlled trials were found to have an effect on blood flow to the brain but the conclusions did not absolutely rule on its effects on cognitive functions. Thus, the study’s evidence was found insufficient to warrant nutritional recommendations.
