OBJECTIVE--To examine changes in the Pima Indian diet composition that may
have played a role in the dramatic rise in the incidence of NIDDM among
Pima Indians over the last century. RESEARCH DESIGN AND METHODS--We
investigated the composition of the foods comparable to those available to
the Pima approximately 100 yr ago, with the aim of reproducing this
traditional diet as faithfully as possible for a dietary intervention
study. An approximation of the traditional diet was ascertained from the
ethnohistoric literature and traditional recipes. RESULTS--We estimated
that the traditional Pima diet, although seasonably variable, was
approximately 70-80% carbohydrate, 8-12% fat, and 12-18% protein. A diet
analogous to the traditional Pima diet is largely reproducible with the
foods available today. Many native foods are available locally and many
commercial products can be substituted when native foods are unavailable.
CONCLUSIONS--The Pima Indian diet of the last century was much higher in
carbohydrate and lower in fat compared with the modern-day Pima diet. Any
changes that this diabetes-prone population can make toward their
traditional diet may help to decrease their incidence of diabetes.
