Evaluation of the relationship between the Mediterranean diet adherence and sleep quality in adults.

PURPOSE: To investigate the association between Mediterranean diet adherence (MDA) and sleep quality in adults. METHODS: This cross-sectional research was conducted among adults aged 19-64 years in Ankara, Türkiye. Data on demographics, education, lifestyle, and physical activity habits were collected. Mediterranean diet adherence was assessed with the Mediterranean Diet Adherence Screener (MEDAS). Healthy eating attitudes were evaluated with the Attitude Scale for Healthy Nutrition (ASHN). Sleep quality was measured with the Pittsburgh Sleep Quality Index (PSQI). Data were gathered using an online format. RESULTS: Among 1031 participants enrolled (74% women), mean age was 28.6 ± 8.3 years. Median age increased with MDA (p = 0.001). As individuals' MDA increased, ASHN total and subgroup scores also increased significantly (p < 0.001). The total sleep duration of the participants with low MDA was significantly lower than the other groups (p = 0.003). Pittsburgh Sleep Quality Index score and MEDAS (ß = - 0.222, p < 0.001), ASHN (ß = - 0.043, p < 0.001) and ASHN subgroups (ß = (- 0.086) - (- 0.031)) were found to have a weakly signficant negative relation. CONCLUSIONS: The findings suggest that healthy eating attitudes and nutritional behavior in accordance with the Mediterranean diet are associated with sleep quality.

Is resveratrol really effective in kidney disease?: A different perspective than ever before.

BACKGROUND: Chronic kidney disease (CKD) is a global health problem and it is stated that the use of resveratrol supplement contributes to the protection of kidney health. In this study, it was aimed to evaluate the effect of resveratrol supplementation on kidney function, inflammation and histopathological findings in rats with experimental adenine-induced kidney damage. METHODS: Three different groups of 10 randomly selected rats were formed. The first group was the negative control group, the second group was the uremic control group (KDG), and the third group was the group in which uremia was created and resveratrol was applied (RG). Kidney damage was induced by administration of 200 mg/kg adenine. Resveratrol supplementation was administered at 20 mg/kg after kidney damage. Serum urea, creatinine, indoxyl sulfate (IS), p-cresol, glomerular filtration rate, C-reactive protein (CRP); interleukin (IL)-6 and tumor necrosis factor (TNF)-α gene expression levels and histopathological findings were evaluated. RESULTS: It was determined that resveratrol supplement applied after the formation of connective tissue in renal failure didn't have an improvement effect on the urine amount, kidney function and inflammatory parameters and histopathological changes (p > 0.05). Just, the increase in the CRP value of KDG (p < 0.05) was not observed in RG. CONCLUSION: The findings suggest that resveratrol administered after kidney damage with adenine has no effect on kidney disease.
