This is a study done in Lebanon (KPD is well-documented in the Middle East). It should be noted that there was one other diet that was examined but it showed no association with diabetes. This diet would be close to a low carb diet.
The findings of this study demonstrate direct associations of the Refined Grains & Desserts and Fast Food patterns with T2D and an inverse association between the Traditional Lebanese pattern and the disease among Lebanese adults.

What should be noted is that this diet maybe safe now but it too is subject to the substitution of ingredients as well so complacency, as regards ones diet, should be guarded against.
