50+ | A diet with nuts keeps your reaction speed up to par

Eating nuts regularly will likely reduce your chances of cognitive decline after age 50. And it also seems that nuts can help keep your reaction speed up to par after your fifties.


50+ | A diet with nuts keeps your reaction speed up to par


Study
The researchers, affiliated with Qatar University, analyzed the data of 1,000 adults who participated in the Qatar Biobank project. The reaction speed of the study participants was determined in tests.

Reaction speed is a biomarker for cognitive abilities; the faster a person can react, the better their cognitive skills are usually.

At the same time, the researchers knew the diet of the study participants.

Results
About forty percent of the study participants consumed nuts less than once a month [low consumers]. About twenty percent of the participants consumed nuts more than 4 times a week [high consumers].

When the researchers compared the study participants who ate nuts once a month or less with the study participants who ate nuts more than once a month, they saw that the latter group responded more quickly. At least, in the age group past fifty.

Mechanism
"Nuts are good sources of polyunsaturated fatty acids, phytosterols, polyphenols, and magnesium. Nuts consumption has been shown to be beneficial for the prevention of many chronic diseases including diabetes and hypertension", write the researchers.

"Since hypertension and diabetes are risk factors for cognitive impairment, it is possible that nuts consumption can improve cognitive function."

"Second, nuts can reduce the A-beta-induced oxidative stress, cell damage, and levels of inflammation. [...] Moreover, nuts consumption can reduce the risk of cardiometabolic dysfunction and maintain endothelial function."
