Abstract

Compared to other North American indigenous populations, Southwest Alaskan Yupiit exhibit very low rates of type 2 diabetes despite the occurrence of common risk factors. Contemporary Yupiit obtain a substantial portion of their calories from traditional foods, which contain high amounts of omega-3 polyunsaturated fatty acids. Epidemiological and experimental animal research has linked glucose and insulin homeostasis with a diet high in omega-3s. This study used an experimental animal model to explore potential diabetes protective effects (for adult offspring) of prenatal maternal nutrition modeled on traditional locally-obtained Yupiit diets. The results of this study showed that the adult offspring whose mothers consumed a diet modeled on traditional Yup’ik foods during pregnancy were more insulin sensitive (less prone to diabetes) than adult offspring whose mothers received a Western diet prenatally. These findings provide further insight into our understanding of the role that specific maternal nutrients play in programming adult metabolism and have significant implications for dietary intervention strategies aimed at preventing type 2 diabetes.
