An Insulin Index of Foods (1994)
&gt; However, some proteinand fat-rich foods (eggs, beef, fish, lentils, cheese, cake, anddoughnuts) induced as much insulin secretion as did some carbohydrate-rich foods (eg, beef was equal to brown rice andfish was equal to grain bread).<p>what? that makes zero sense, at least in case with fat. anybody got quick explanation for this?<p>Edit: found the TLDR explanation in another part of the paper<p>&gt; postprandial insulin responses are not always proportional to blood glucose concentrations or to a meal&#x27;s totalcarbohydrate content. Several insulinotropic factors are knownto potentiate the stimulatory effect of glucose and mediatepostprandial insulin secretion. These include fructose, certainamino acids and fatty acids, and gastrointestinal hormones suchas gastric inhibitory peptide, glucagon, and cholecystokiin(25, 26). Thus, protein- and fat-rich foods may induce substantial insulin secretion despite producing relatively small bloodglucose responses.
