I patients when caught early. It has only been a very few years that we have known about the direct connection between Type 1 Diabetes and caseine. We don't know how long the problem continues after stopping the stimulus OR how much damage the pancreatic cells can endure before it becomes irreversable. If tthere is caseine in soy cheese, I would avoid it. I have not heard of niacinamide reversing this but would be VERY interested in any research you can share that I could learn from.
Refined carbohydrates create a special stress on the pancreas.
Let us know what you learn.
