are dairy and red meat uniquely insulinogenic?


The original 1997 paper by Susan Holt et al [1] looking at the food insulin index suggested that dairy and meat proteins may be more insulinogenic than vegetable proteins.  The problem with this study was that 38 data points weren’t really enough to draw a meaningful conclusion.

You may have also heard it said that “diary is insulinogenic”, suggesting that perhaps dairy products have some special hormonal property that requires more insulin than other foods. [2]

In order to test whether particular groups of foods might have unique insulinogenic properties I have plotted the insulin response for various types of proteins separately (note: without taking fibre into account).

Fish (based on only four data points) and dairy (based on thirteen data points) seem to have the greatest insulin reaction while vegetables and animal protein have the lowest insulin response.

However if we account for the indigestible fibre (i.e. net carbs) then legumes (based on only five data points) appear to require more insulin while fruit and vegetables require less insulin.

Based on the available data it does not appear that that insulin response is influenced significantly by anything other than carbohydrates, fibre and protein in a food.

So in summary, there is very little difference in the insulin response of the various foods once fibre is taken into account.

  • non-fibre carbohydrates require insulin;
  • protein requires about half as much insulin as carbohydrate; and
  • fibre does not require insulin or raise blood sugar.
