"Hemoglobin A1C, 5, less than 5. The data in the literature that I quote shows hemoglobin A1C of less than 5 is associated with less diabetes and disorders of chronic disease. As hemoglobin A1C creeps up by a tenth of a point, that change is dramatic, and your risk of disease as you age goes up."
Dr. Comite advocates for a hemoglobin A1C target of under 5, significantly lower than current medical guidelines which consider up to 5.6 normal and 5.7-6.4 prediabetic. She cited literature showing that each tenth of a point increase above 5.0 dramatically raises the risk of chronic disease and all-cause mortality, challenging standard preventative care thresholds.
