Determining the relationship between diet acid LOAD and plant-based DİET index and mood state in adult women

The present study aimed to examine the possible relationship between plant-based diet index and dietary acid load with depression, anxiety, and stress. A total of 231 healthy women aged 19-39 years participated and data were collected through online and telephone interviews. The mood state of participants was measured using the DASS-21 scale (Depression-Anxiety-Stress Scale), and their nutritional status with a 24-hour retrospective food consumption record, Plant-Based Diet Index scores with a quantitative food consumption frequency questionnaire, the potential renal acid load of the diet (PRAL) and net endogenous acid production (NEAP) were calculated. It was determined that consuming potato chips, fruit juices, and sugar-sweetened beverages was positively associated with DASS-21 total scores, and negatively correlated with eggs and olive oil consumption. Dietary carbohydrate intake (g) was positively correlated with DASS-21 total score (r=0.13 p=0.04). Daily dietary intake of vitamin C, total folic acid, and iron were negatively correlated with DASS-21 total score (respectively; r=-0.18 p=0.04, r=-0.13 p=0.04, r= -0.13 p=0.03). Participants with a high general plant-based diet index score had a higher mean anxiety score (p<0.05). In addition, a positive correlation was determined between the general plant-based diet index and DASS-21 total score and anxiety (p<0.01). Participants with a high healthy plant-based diet index score have a lower mean score in all subgroups of the DASS-21 scale (p>0.05). Participants with high unhealthy plant-based diet index scores had DASS-21 total (p<0.01), depression (p<0.01), anxiety (p<0.05), and stress (p<0.05) scores. the average was higher. In addition, unhealthy plant-based diet index scores and DASS-21 total (r=0.19 p=0.003), depression (r=0.19 p=0.003), anxiety (r=0.17 p=0.003), and stress (r =0.15 p=0.01) scores were positively correlated. The dietary acid load can be related to mood. Individuals with higher PRAL and NEAP values had higher DASS-21 scale scores, but this difference was not statistically significant (p>0.05). A positive correlation was found between PRAL values and stress scores (p<0.05), and no correlation was found between other DASS-21 scale scores and dietary acid load values. As a result, a potential relationship between plant-based diet index and mood state was found, but no strong relationship was found between dietary acid load and mood. Clinical and observational studies with larger sample sizes are needed on this subject.
