A randomized clinical trial published in the journal Nutrients found that a dietary regimen containing walnuts may improve stress and brain health among stressed university students.
“Here, using a randomized clinical trial, we aimed to investigate the effects of academic stress and daily walnut consumption in university students on mental health, biochemical markers of general health, and the gut microbiota,” the authors wrote in the journal article.
“We found academic stress had a negative impact on self-reported mood and mental health status, while daily walnut consumption improved mental health indicators and protected against some of the negative effects of academic stress on metabolic and stress biomarkers.”
The study involved undergraduate student participants between the ages of 18 and 35 who were recruited at the University of South Australia. 80 participants were considered eligible and took part in the research.
