Eat Peanuts Daily for a Sharper Mind


A research was carried out with a gaggle of 63 wholesome individuals aged between 19 and 33, who had an everyday portion of peanut merchandise of their day by day consumption to look at the helpful impact of peanut merchandise on cognitive operate and stress response.

Then via a broad battery of cognitive checks and analytical checks associated to biochemical indicators of the stress response (corresponding to cortisol), researchers analyzed the well being advantages of peanuts.


The outcomes revealed a rise within the fecal short-chain fatty acids from the intestine, other than particular biomarkers of peanut corresponding to long-chain saturated fatty acids and sure polyphenols, all are bioactive compounds associated to many well being advantages.

They additionally didn’t discover out any important variations between the consumption of peanut butter and peanuts on cognitive operate or stress response biomarkers.

Later, researchers needed to research whether or not the introduction of peanut merchandise in a nutritious diet may have a optimistic impression on the microbiota-gut-brain axis and contribute to the prevention of future ailments.

Though there may be proof suggesting a bidirectional relationship between phenolic compounds and intestine microbiota, some authors noticed an enchancment of mind and basic well being after a polyphenol-rich intervention.

So, they postulate that the prebiotic substances current in peanuts corresponding to polyphenols can have an effect on cognition and temper not directly via interactions with the intestine microbiota and improve microbiota-gut-brain axis.

To verify these findings, they included a management group within the research and gave the group a placebo with a peanut-based oil and the identical composition of macronutrients of peanut butter however with out prebiotic substances and located that it didn’t have the identical helpful impact.

“The high content of prebiotic fibre and polyphenols in peanuts could explain its beneficial effects on the gut microbiota. Due to its poor absorption, fibre and most polyphenols directly reach the colon, where they are metabolized by the microbiota and can modulate the brain biochemistry by acting as neurotransmitters in the central nervous system” says Sara Hurtado, lecturer on the Faculty of Pharmacy and Food Sciences of the University of Barcelona.

Another research that analyzed the connection between polyphenols in meals and organic samples confirmed promising outcomes that require affirmation in research carried out with a bigger group of individuals.

In future research, researchers wish to broaden the analysis on the results of the consumption of peanut merchandise and their bioactive compounds on the microbiota via microbial composition, microbiome, lipidomic and transcriptomic analyses.
