In a study of lifestyle habits among the Pimas, researchers found that those who consumed an "Anglo" diet were nearly three times as likely to develop diabetes over about 6 years, compared with those who followed a "traditional" diet rich in squash, melons and legumes.
Those who consumed elements of both diets were also at increased risk.
The Pima Indians of Arizona have undergone a rapid transition from a traditional lifestyle that included a healthy diet and exercise through work in fields, to a "Westernized" lifestyle marked by high-fat foods and less physical activity.
As a result, rates of obesity and chronic diseases characteristic of Western populations have soared.
In fact, the Pima Indians have the highest rate of type 2 diabetes in the world.
But the Pimas are only one of myriad groups whose health is being affected by today's lifestyles. Overall, diabetes was diagnosed in 22% of the study participants, predominately women.
Foods in the traditional Pima diet do not cause blood sugar to surge in the way many foods included in the Anglo diet do. Additionally, a healthier diet is also associated with a healthier overall lifestyle that includes exercise.
Type 2 diabetes occurs when the body loses its sensitivity to insulin, a hormone that regulates blood sugar, or glucose. When insulin sensitivity wanes, glucose rises to levels that can, over time, increase a person's risk of developing heart disease, kidney failure, nerve damage and blindness.
In another study, diabetic Pima Indians and whites who consumed a traditional Indian diet for just 2 weeks improved their glucose tolerance and lowered their cholesterol.

This of course is not new information to those who have been following this newsletter for any length of time, who know that I do NOT advise people to consume grains.
Most type 2 diabetes is caused by consuming these foods, as well as sugar, and elimination or drastic reduction of them can bring about a dramatic improvement in control for nearly all type 2 diabetics.
