A research printed within the journal Medical Vitamin supplies new data on the well being results of a food plan wealthy in nuts. In response to the research, centered on the consumption of peanuts, the each day consumption of merchandise from this nut may have helpful results on the cognitive operate and stress response in younger and wholesome people.
The research is led by Rosa M. Lamuela, director of INSA-UB and lecturer on the College of Pharmacy and Meals Sciences of the College of Barcelona, and member of the Physiopathology of Weight problems and Vitamin Networking Biomedical Analysis Centre (CIBEROBN). This paper additionally counts on the participation of members of the Hospital Clínic and IDIBAPS.
Nuts excessive in power
The peanut (Arachi hypoagea) is a leguminous plant from South America which was launched in Europe within the 18th century. It produces a fruit of nice dietary curiosity, wealthy in fatty acids, proteins, fiber, polyphenol and different bioactive compounds of potential curiosity for our well being.
The research was carried out with a bunch of 63 wholesome folks aged between 19 and 33, who included an everyday portion of peanut merchandise of their each day consumption. “Most dietary intervention research have been completed in a inhabitants with weight problems, metabolic syndrome or who’re prone to persistent metabolic illness. On this inhabitants that’s in danger, it’s simpler to look at a helpful impact altering the meals sample or introducing a wholesome meals of their recurring food plan,” notes lecturer Rosa M. Lamuela.
“Nonetheless, ─she continues─ within the research we noticed the helpful impact of the each day consumption of peanut merchandise on the advance of the cognitive operate and stress response in a younger and well being inhabitants, a bunch by which any well being impact is harder to look at.”
The workforce analyzed the potential well being results of the consumption of peanuts via a broad battery of cognitive assessments and analytical assessments associated to biochemical indicators of stress response (equivalent to cortisol). The outcomes additionally revealed a rise within the fecal quick chain fatty acids ─from the microbiota─, other than particular biomarkers of this nut, lengthy chain saturated fatty acids and sure polyphenols, all of that are bioactive compounds associated to many well being advantages.
In response to the conclusions, the compounds that would contribute to the well being results described by the workforce are some bioactive compounds equivalent to resveratrol and p-coumaric acid, in addition to short-chain fatty acids and peanut-specific long-chain saturated fatty acids.
The researchers didn’t discover vital variations between the consumption of peanut butter and peanuts and cognitive operate or stress response biomarker. Furthermore, every part means that the age variable didn’t affect the statistical analyses since there have been no modifications as a result of age variations. “That is one other factor of curiosity within the research, since many dietary research present significative variations in sufferers or topics with a excessive threat of struggling illnesses, particularly the aged,” observe the specialists.
Consumption of peanuts and intestine microbiota
The workforce analyzed whether or not the introduction of peanut merchandise in a nutritious diet may have a constructive affect on the microbiota gut-brain axis and subsequently contribute to the prevention of future illnesses. “There may be proof suggesting a bidirectional relationship between phenolic compounds and intestine microbiota, and a few authors have noticed an enchancment of mind and common well being after a polyphenol-rich intervention. The prebiotic substances current in peanuts ─equivalent to polyphenols─ can have an effect on cognition and the temper not directly via interactions with the intestine microbiota and improve microbiota gut-brain axis,” notes researcher Sara Hurtado (UB-INSA-CIBEROBN).
To verify these outcomes of the dietary research, the workforce 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, observing it didn’t have the identical helpful impact.
“The excessive content material of prebiotic fiber and polyphenols in peanuts may clarify its helpful results on the intestine microbiota. Resulting from its poor absorption, fiber and most polyphenols immediately attain the colon, the place they’re metabolized by the microbiota and may modulate the mind biochemistry by performing as neurotransmitters within the central nervous system” says Sara Hurtado. “Quick-chain fatty acids ─equivalent to acetic, propionic, and butyric acids, are the principle metabolites produced by intestine microbiota, and so they appear to have results in opposition to varied illnesses, together with melancholy and neurodegenerative illnesses.”
The Analysis Group on the Evaluation Pure Polyphenols and different bioactive compounds current in meals led by Rosa M. Lamuela has a distinguished analysis expertise within the research of polyphenols in meals and organic samples, and has taken half in worldwide tasks equivalent to PREDIMED, a multicentre medical trial on the Mediterranean food plan and well being, within the subject of dietary epidemiology.
This research exhibits promising outcomes that require affirmation in research carried out with a bigger group of individuals. Concerning future research, the workforce needs to broaden the analysis on the consequences of the consumption of peanut merchandise and its bioactive compounds on the microbiota via microbial composition, microbiome, lipidomic and transcriptomic analyses. Researchers need to search for extra explanations within the research of the mechanisms which are concerned within the microbiota gut-brain axis after the consumption of peanut merchandise.
The paper printed within the journal Medical Vitamin has been carried out inside the framework of the ARISTOTLE undertaking, an initiative to investigate the prebiotic and postbiotic results of the consumption of peanut merchandise pushed by The Peanut Institute (United States). The research additionally counted on the help from companies linked to the meals sector that didn’t participate within the experimental design nor the analysis protocol of the research.
