Findings of previous studies on associations between dairy consumption and metabolic health status were inconsistent. This study aimed to assess the link between consumption of dairy foods and metabolic health status, brain-derived neurotrophic factor (BDNF) and adropin levels in adults. Cross-sectional. An observational study in Isfahan, Iran. Adults (n=527) selected by multistage cluster random sampling. Dietary intakes were assessed via a validated 168-item food frequency questionnaire. Anthropometric indices, blood pressure and biochemical parameters were assessed. The criteria proposed by Wildman Participants had a mean age of 42.66 years (45.7% women). Moderate consumption of total dairy was, respectively, linked to 58% lower odds of MU (OR Moderate consumption of total and low-fat dairy was associated with lower odds of being metabolically unhealthy in Iranian adults, but high-fat dairy intake was not. Hypertension was less common among individuals with higher dairy intake. No association was found between dairy intake and serum levels of BDNF or adropin. Show less

The connection between the diabetes risk reduction diet (DRRD) score and metabolic health is not exactly clear. This study examined the association between DRRD score and metabolic health (MH), serum adropin, and brain-derived neurotrophic factor (BDNF) in Iranian adults. This cross-sectional investigation employed a sample of 527 adults (45.7% females) within the age range of 20 to 65 years, who were selected via a multistage cluster random sampling technique. Dietary assessment of participants was evaluated utilizing a validated food frequency questionnaire, while a fasting blood sample from each participant was procured to analyze biochemical parameters. MH status was ascertained according to the criteria delineated by Wildman et al. The DRRD score was calculated based on nine elements. After adjusting for potential confounders, no significant association was observed between higher DRRD score tertiles and odds of metabolically unhealthy status (OR = 0.99; 95% CI: 0.58–1.70). Individuals in the highest tertile of DRRD score demonstrated a 44% (95% CI: 0.33–0.96) significant reduction in the odds of developing hypertriglyceridemia compared to those in the lowest tertile. However, no significant reduction was observed in other Metabolically Unhealthy (MU) components. Also, no significant difference was observed in BDNF and adropin levels among individuals in DRRD score tertiles. A Higher DRRD score was associated with reduced odds of hypertriglyceridemia, but no significant associations were observed with other metabolic unhealthy components or BDNF and adropin levels.
