This is a statistical statement, and "normal" is being used in that context.
The assumption here is that blood glucose measurements taken in a random
sample of non-diabetics under particular conditions will produce a range of
readings, and that it will have a discernable and predictable frequency
distribution. Assuming that to approximate a normal distribution, the most
frequent reading will be 90mg/dL. Without having the variance to go along
with this statement, it is impossible to know exactly what the range might
be. Having said that, it's entirely possible - even likely that *some*
healthy people will have fasting glucose measurements over 120mg/dL, and
some will have measurements under 70mg/dL.
I will also note that your quote says "rarely" will BG rise over 140 in a
non-diabetic. That means that there are cases where it has/does.
This is the very essence of YMMV.
