Abstract

Purpose: To evaluate and quantify the association between consumption of specific food groups/macronutrients and concentrations of serum insulin-like growth factor 1 (IGF-1) and insulin-like growth factor-binding protein 3 (IGFBP-3). Subjects and Methods: Data from a comprehensive food-frequency questionnaire administered to 115 healthy subjects were used to study cross- sectionally the relationship between nutritional factors and circulating IGF- 1 and IGFBP-3 concentrations. Adjustment for the effect of total energy intake and a series of epidemiologic parameters (age, sex, height, body mass index, smoking, alcohol consumption, and coffee drinking) was implemented through multivariate linear regression. Results: We observed that serum levels of IGF-1 are positively associated with consumption of red meats, fats, and oils. In addition, serum levels of IGF-1 are independently and positively associated with energy intake from lipids and negatively associated with energy intake from carbohydrates. Finally, serum levels of IGFBP-3 are independently and negatively associated with energy intake from saturated fat. Conclusion: Serum IGF-1 and/or IGFBP-3 concentrations are associated with red meat, carbohydrate intake, and fat intake and, thus, may mediate the effect of these dietary factors on the pathogenesis of several disease states. Additional studies are needed to further quantify these associations and elucidate the underlying mechanisms.
