That all depends really. You cant just arbitrarely get diabetes just becasue you drink alot of soda. My dad is 53, Diabetes is in the family, and he drank root beer almost all his life and still dosent have it. Its all paranoia imo. Oh, and he had his pancreas removed becasue it was cancerous in his early 20s. So, the thing that regulates insuline isnt there either.
