The American Diabetes Association has an online test you can take to see whether you are at risk of having diabetes.
For material you can hold in your hands, the St. Louis Public Library has plenty of options.
From the American Diabetes Association, there's the cookbook Magic menus for people with diabetes and the health book Ask the experts: expert answers about your diabetes from the pages of Diabetes forecast, and there are lots more cookbooks and health information books, including The 8-week blood sugar diet: how to beat diabetes fast (and stay off medication) by Dr. Michael Mosley and Diabetes meal planning made easy by Hope S. Warshaw, and currently on order: The case against sugar by Gary Taubes.
We also have exercise videos like Yoga for the rest of us. Easy yoga for diabetes with Peggy Cappy.
