In non-diabetics the insulin response to protein is usually only 20-30% of the response you would get from an equal dose of glucose. In diabetics, however, the insulin response to protein can be as high as 94% of the equivalent glucose response.



Furthermore, high-protein foods frequently stimulate insulin to a similar, or sometimes even greater, degree than high-carbohydrate foods. For example:
