The dietary management of diabetes in adults.

The ultimate object of all types of dietary management before the introduction of insulin was to prevent emaciation and death: the consequences of metabolic derangements due to lack of insulin. Now, while dietary therapy continues to be important in minimizing the requirement for endogenous insulin or in balancing administered insulin, the major objects are changing to prevention of large vessel and microvascular disease. The next decade will probably see a more widespread introduction of diets containing a lower proportion of energy derived from fat. The increased carbohydrate intake will almost inevitably result in increased dietary fibre intake. Whether David Jenkins' Lente carbohydrate foods (those containing viscous unabsorbable polysaccharides) will prove to be of lasting value is not yet known. Since galactomannans occur in legumes perhaps we should consider the possibility of diets containing large proportions of legumes: a twentieth century 'Legume cure'? If this should prove of value it would not have excited ancient Indian physicians who wrote (in the Caraka-Samita) of their use of legumes in the treatment of glycosuria, at least as early as the first century AD, before Aretaeus had applied the term diabetes.
