My husband has Type 1 Diabetes and he was told it came from a virus from when he was 6. Type 2, Diabetes, it most definitely comes from sugar. I’ve battled pre Diabetes and have watched how sugar really effects this over the years. The amount of sugar we take in, in the USA is alarming. Not just in the form of sugar foods but foods where they add sugar to it that will spike the blood sugar, foods we wouldn’t suspect it being in. It wasn’t until I got rid of most sugar From my diet did I get rid of the pre Diabetic state I was headed for. Makes me worried for the future generations, my children and beyond as it seems to be increasing with each generation.
