Walnut consumption improves mental health indicators and negates some negative effects of academic stress on students' health and gut microbiota, especially in females.
In the study, the researchers launched a randomized clinical trial to study the effects of academic stress and daily walnut consumption on undergraduate students' mental health, general health biomarkers, and the gut microbiota. The specific aim was to examine the implications of stress and diet interplay, focusing specifically on the consumption of walnuts due to their previously demonstrated positive impact on mental wellbeing.
In analyzing the results, they found that academic stress negatively affected the self-reported mood and overall mental health of the students. However, a daily intake of walnuts appeared to improve the mental health indicators. Notably, it provided a buffer against the adverse effects of academic stress on metabolic and stress biomarkers. Particularly in female students, academic stress was linked to reduced gut microbial diversity, a negative effect which walnut consumption seemed to counteract. The effects on male participants could not be definitively ascertained due to the smaller participant size.
