60 - re 40 - As a long time diabetic, i have studied diabetes for many years, and also lived worked and traveled among many peoples.
I have come to the concoclusion that people who survived in starvation/low carbohydrate situations (all far northern peoples - from scandanavians and russians and germans and laplanders and eskimos), and people of the deserts of the mid-east - have bodies designed by nature to survive on high protein, high fat, and low carbohydrate diets. When exposed to diets high in carbs they get sick and die, particularly from diabetes.
So, this explains, how our plains indians, who survived on the buffalo herds, have such high rates of diabetes too. Arabs and Egyptians (desert dwellers - with few carbs) also have high rates of diabetes.
Those recommending high carb diets for diabetics are actually killing them.
While Italians and south east asians eat major amounts of carbs (wheat and rice) and have low rates of diabetes.
So, look to the ancestors of your bodies to find your best diet, as one recommended diet may kill you if your body is from another area.
I agree with you. I also believe your blood type gives a hint of what kind of diet is good for you. Blood type "O" gets along just fine with high protein diet such as red meats. Type "A" should avoid animal fats.
In my own case (type "O") I feel great when I start out with a high protein breakfast (Egg, yellow cheese, cream cheese on whole wheat toast). If I eat a sugary high carb cereal breakfast, I feel tired by noon.
