She doesn't have to have diabetes type 2 anymore, at least.
Read "Wheat Belly" by William Davis MD and give up wheat. Hubby did so and his Sugar levels have been NORMAL for the four years since he read the book and gave up wheat.
I'm dead serious. He was at the point of learning how to give himself insulin shots.
His A1C tests have been normal for four years now.
Unfortunately, he was a diabetic long enough to cause kidney damage.
Stop being a diabetic NOW.
It can be done; I don't care what your doctor says. Hubby gave his advice to two others we know of - BOTH of them gave up wheat and THEIR Sugar levels are now in the normal range.
