Adding walnuts to daily diet shows positive effects on mental health

It is common for undergraduates to have poor mental health due to academic stress. There is an interaction between stress and diet, and stress influences dietary choices. Nutritional interventions may be effective in preventing mental health decline due to the complex bidirectional interactions between the brain, gut, and gut microbiota. It has been shown to have positive effects on mental health.

In a new study, scientists from the University of South Australia aim to investigate the effects of academic stress and daily consumption of walnuts in college students on mental health, biochemical markers of general health and the gut microbiome. They found that daily consumption of walnuts improved mental health indicators and protected against the negative effects of academic stress on metabolic and stress biomarkers.

In other words, walnuts may counteract the effects of academic stress on the gut microbiome during periods of stress, especially in women.

Principal Investigator and PhD student Mauritz Herselman said: The results show growing evidence linking walnuts to improved brain and gut health. ”

“Students experience academic stress while studying, which negatively affects their mental health. They are especially vulnerable during exams.”

“Clinical evaluations of 80 college students, divided into treatment and control groups, were conducted over three periods: at the beginning of the 13-week semester at the university, throughout the study period, and two weeks after the study period. At these three intervals, the treatment group was given walnuts daily for 16 weeks.”

“We found that people who consumed about half a cup of walnuts daily showed improvements in self-reported mental health measures. showed.”

In the weeks leading up to the exam, control group students experienced more stress and despair than treatment group students. I also noticed that my symptoms were greatly reduced.

Previous research has shown that walnuts are rich in omega-3 fatty acids, antioxidants, melatonin (the sleep-inducing hormone), polyphenols, folic acid and vitamin E, all of which support brain and gastrointestinal health. is shown.

Mr. Haselman “The World Health Organization recently stated that at least 75% of mental health disorders affect people under the age of 24, making undergraduates particularly vulnerable to mental health problems.”
