Beyond that, blood sugar spikes and insulin responses are NORMAL.  The current obsession with them is the sickness.  The only time blood sugar matters is when it doesn't come down rapidly, meaning you have become hyperglycemic or diabetic... and the cause of that is NOT blood sugar, but pancreatic/liver dysfunction generally caused by excessive fat.

That isn't to say that keeping blood sugar artificially low all-the-damn-time doesn't have benefits, like cancer starvation or weight control.  It might.  I don't know.
