Diabetes is diagnosed solely based upon numbers, meaning that diabetes and pre-diabetes are the same disease process and just one blood sugar point can differentiate the two. Diagnosis requires 3 separate fasting blood glucose
tests, spaced apart. A lot of
things can affect your readings, aside from just diet- exercise, hydration, stress, illness, etc. I would just continue to lead a healthy lifestyle. Keep an eye on it, but don't obsess over it.
