Effects of the Mediterranean diet adherence on body composition, blood parameters and quality of life in adults

BackgroundIt has been reported that Mediterranean diet (MD) may improve quality of life and may reduce the risk of chronic diseases such as metabolic syndrome, type 2 diabetes, cardiovascular diseases (CVD), some neurodegenerative diseases and cancer. Therefore, this study aimed to determine adults’ adherence to the MD and evaluate the effect of the adherence to the MD on anthropometric measurements, specific biochemical parameters and quality of life.MethodsA total of 142 volunteer adults were included. Food frequency questionnaire, MD adherence with 14-item scale, quality of life, anthropometric measurements via bioelectrical impedance analysis and certain blood parameters were evaluated.ResultsOut of 14 points, the mean MD adherence score of the participants was 6.89. The mean fat mass was significantly higher in those with low MD adherence (p=0.024). The results of other anthropometric measurements (except height) were higher in those with low MD adherence, though results were non-significant. The participants with high adherence to the MD had lower levels of fasting blood glucose (FBG) (p=0.041), insulin (p=0.019) and triglyceride (TG) (p=0.012) compared with those with lower adherence. No significant relationship was found between the MD and quality of life and other blood parameters.ConclusionAccording to our study, MD adherence was associated with decreased fat mass, FBG, insulin and TG levels which suggests that the MD may be useful in the treatment of some chronic diseases such as obesity, diabetes, metabolic syndrome and CVD. However, more clinical trials may be performed to determine the relationship between MD and chronic diseases.
