My dad was diagnosed with Type 2 diabetes about 10 years ago.  My brother was recently diagnosed with Type 2 diabetes within the last 5 years.  Diabetes has affected my brothers vision resulting in numerous laser treatments to stop the hemorrhaging behind his eyes.  He also has lost feeling in some of his limbs. 

So what does that mean for the rest of the family?  To me it means we are all predisposed to it in my family.  That was an impetus for me to lose 120 pounds about 3 years ago.  Type 2 diabetes can sometimes be reversed by diet and exercise.  I've seen it first hand.

In my weight loss classes a number of the men and women lost between 20 and 30 pounds and could completely get off of insulin or at the very least reduce their insulin intake.

Now scientists are learning why drinking coffee can prevent diabetes.  Coffee, contains compounds that inhibit hIAPP (human islet amyloid polypeptide) a substance linked to diabetes.
