  1. Fulltext. Low dietary fiber and high protein intakes associated with newly diagnosed diabetes in a remote aboriginal community.

    Article - En anglais


    The high prevalence of diabetes mellitus in North American aboriginal populations may be due to recent changes in lifestyle, including the adoption of a high-fat, low-fiber diet.

    To determine whether fat or fiber intakes were associated with new cases of diabetes, we studied 72% (728/1018) of residents aged>9 y from a remote aboriginal community in northern Ontario using the 75-g oral-glucose-tolerance test and 24-h dietary recall.

    The mean fat intake of this population (36% of energy) was typical for North America, but fiber intake (1.2 g/MJ) was very low.

    Logistic-regression analysis, adjusted for age, sex, and body mass index, showed that a 1-SD increase in fiber intake reduced the risk of having diabetes by 39% (P=0.026) whereas the same increase in protein intake increased the risk by 38% (P=0.027).

    There was no significant effect of energy, fat, starch, or simple sugars.

    These data support Trowell's original dietary-fiber hypothesis that « ... dietary fiber depleted starchy foods are conducive to the development of diabetes mellitus in susceptible human genotypes. ».
