I read in one of your books that dairy food causes a higher insulin response than would be expected by its low GI. Does cheese cause a high insulin response or just milk and yoghurt?
Protein is what called an insulin secretagogue (this means it stimulates insulin secretion). It isn’t necessarily a high insulin response. For most foods the glycemic response parallels the insulin response, so low GI would also be low insulin. However with foods that are sources of both carbs and protein (like dairy foods), this relationship is clouded by the insulin-stimulating action of protein. In response to your specific question, we expect that cheese (being a source of protein) would also stimulate some insulin secretion.
