Throughout my little health research I've been doing through the years. I believe that the cause of diabetes stems down further, yet not more complicated than we think.
I believe diabetes simply emerges from some sort of vitamin/mineral deficiency due to a poor diet, which causes the pancreas issue. The whole too much sugar story is a half-truth I believe, because while eating sugar all day is bad for you so is eating strictly anything else all day, as you will not be diversifying your nutrient intake which is essential.
