Impact of DASH and Mediterranean diets on mood and happiness in young adult males: a cross-sectional study

A number of mental health advantages have been associated with the Mediterranean diet (MED) and the Dietary Approaches to Stop Hypertension (DASH). However, their specific impact on young adults, a particularly vulnerable group, remains unclear. This study by Kazeminejad et al. (2025) looked at the connection between young Iranian boys’ eating habits and their degrees of pleasure or mood. The study included participants aged 18–28 years (mean age: 23.65 ± 1.74 years) with an average BMI of 24.23 ± 3.82 kg/m². After controlling for confounding variables, individuals in the highest DASH adherence group had a 54% lower likelihood of experiencing poor mood than those in the lowest adherence group. Additionally, a strong inverse association was found between DASH adherence and lower happiness scores. Nevertheless, there was no discernible connection found between happiness or mood and the Mediterranean diet. According to these results, young male adults who follow the Dietary Approaches to Stop Hypertension (DASH) diet may be less likely to experience sadness and low mood. To confirm these findings, more prospective research is required. [NPID: DASH, Mediterranean diet, mood, happiness, cross-sectional]
