A dietary pattern characterized by high consumption of whole-grain cereals and low-fat dairy products and low consumption of refined cereals is positively associated with plasma adiponectin levels in healthy women

Metabolism. 2008 Jun;57(6):824-30. doi: 10.1016/j.metabol.2008.01.027.


In light of the potential beneficial effects of adiponectin on insulin resistance, metabolic syndrome, and cardiovascular risk, it is becoming increasingly important to identify all modifiable factors, including dietary patterns, that may affect circulating adiponectin concentrations. The aim of the present study was to explore potential associations between dietary patterns and plasma adiponectin levels using principal component analysis (PCA) in a sample of apparently healthy adult Mediterranean women. Two hundred twenty women were enrolled in this study. Anthropometric and body composition measurements were performed in all subjects. Blood samples were taken, and adiponectin concentrations were measured. Food intake was evaluated by 3-day food diaries, and PCA was used for the identification of the participants' dietary patterns. The PCA identified 10 dietary components explaining 82% of the total variance in food intake. Bivariate correlation between circulating adiponectin levels and dietary components revealed a positive significant association only with the first component that was characterized by high intake of whole-grain cereals and low-fat dairy products as well as low intake of refined cereals (P = .04). This association remained unchanged after controlling for potential confounders (standardized beta coefficient = 0.18, P = .03). A dietary pattern characteristic of consumption of alcoholic beverages was found to be marginally related to adiponectin levels in the multivariate model (standardized beta coefficient = 0.14, P = .10). Our data indicate that a dietary pattern characterized by a high consumption of whole-grain cereals and low-fat dairy products is modestly positively associated with adiponectin concentrations.
