I started taking care of my grandmother and was able to lower her A1C from 7.6 to a 5.7 in 6 months simply buy making real food and avoiding the shelf stable foods. Whole Foods are your answer. She had been taking insulin for 40 years. That did not stop but we were able to stop all her medications for diabetes outside of the long lasting and short insulin.

You need to eliminate sugar. Most important, not only for your A1C but also your general health.
