We all know some people can tolerate carbs better than others. Is salivary amylase the dominant factor in that?
Plasma insulin concentrations in the High Amylose group were significantly higher than baseline early in the testing session, whereas insulin concentrations in the Low Amylose group did not increase at this time. Following ingestion of the glucose solution, however, blood glucose and insulin concentrations did not differ between the groups. These observations are interpreted to suggest that HA individuals may be better adapted to ingest starches, whereas LA individuals may be at greater risk for insulin resistance and diabetes if chronically ingesting starch-rich diets.
