The American Diabetes Association (ADA) states that a baseline concentration (also known as your fasting level, that is, your glucose level first thing in the morning before eating) between 60 and 100 mg/dL is “normal”; that between 100 and 126 mg/dL indicates prediabetes; and anything above 126 mg/dL indicates diabetes. But what the ADA describes as “normal” may not actually be optimal. Early studies showed that the thriving range for fasting glucose may be between 72 and 85 mg/dL. That’s because there is more likelihood of developing health problems from 85 mg/dL and up.
