title: Dietary self-selection in diabetic rats: an overview.
abstract: The literature concerning dietary self-selection patterns of diabetic rats is reviewed and compared with new data. There is agreement among the various investigators as to the dietary choices observed following induction of diabetes, regardless of the diabetogenic treatment used. That is, moderately diabetic rats select a high fat, low carbohydrate diet, whereas more severely diabetic animals consume high protein, low carbohydrate diets with little change in fat consumption relative to nondiabetic controls. Even very midly diabetic rats reduce carbohydrate intake. Evaluation of metabolic status of diabetics suggests that with severe diabetes, the beneficial reduction of plasma glucose seen with consumption of a high fat diet may be offset by extreme elevations in ketone and triglyceride levels. Moreover, the hypothesis that diabetic rats are insensitive to carbohydrate calories seems weakened by evidence of reduced food intake following carbohydrate consumption either in solutions or as a gastric load. These findings are discussed in terms of "dietary wisdom" as first proposed by Richter.
