I am on The Mayo Clinic Diet diabetes plan. You can access this a couple of ways, there is a book available on Amazon, The Mayo Clinic Diabetes Diet, a journal that goes with it. Lots of good info on how to choose your foods. This Diet plan is also available online, you pay for it. It includes an app, a website, tracking, recipes, lessons etc. I love it, I like to track food exchanges and get the nutrition info also. You can use their recipes or adjust your own.
The American Diabetes Association also has a food hub with lots of recipes, also many books to choose from.
Your Dr can refer you to a diabetes educator/dietician that insurance will pay for and will really help.
