Blood glucose levels rising to 120-140 mg/dL are considered normal human physiology and do not activate the polyol pathway or increase methylglyoxal production.

“having a blood sugar that goes up to 120 even 130 140 this is normal human physiology and is not problematic for humans and really there's no evidence that that will cause this polyol pathway to become activated or fructose to be actually created within a cell and increased methylglyoxal”
