I recently learned that both of my parents are close to becoming diabetic. My dad was told he is glucose intolerant or boderline diabetic. My mom had a test come back positive for diabetes prior to her recent surgery to remove her gallbladder and she will take another test for diabetes in a few months. Both of my parents are in their late forties and I am 26, but I want to make changes now so that I don't have to deal with these issues in the future. I work out fairly regularly, I'm not overweight, and I don't eat red meat or pork. What else can I do to prevent becoming diabetic?
