Title: A Question For Kurt Hey there, used to get on this board quite a bit. To try and give a hand to those in need of some quality info. Anyway, I'm a biochemistry major who plans on going into endocrinology. Got a question for you! Milk products have a low GI but a very high Insulin index. Some(especially fermented ones) up to six fold. Now cheese is not neccesarily high though. It's fairly low. The person who did this research, Jeanie brand-miller, same person that came up with the Glycemic index, told me via e-mail that she believes it was the bovine protiens that cause this. I however, really feel that it is the lactose from the milk that is causing the insulin secretion. Like you said the body does use lactose sort of like fructose in many ways. Just curious what's your opinion and have you read the research that I am talking about? -John L. Name: John Date: Oct. 29th, 2001 Title: Re: A Question For Kurt Late reply, had exams. An increased GI rating in the blood is not the only thing that will raise insulin levels. Protein rich food can stimulate a modest insulin raise. Even adding fat will also raise insulin. Adding fat will also lower plasma glucose levels. So it's hard to compare GI and the Insulin index. Lactose is a chain of galactose and glucose. Galactose is metabolized differently from glucose and fructose. I found a good journal on pubmed, but unfortunately I do not have a membership so I could only see the abstract. From what little information the abstract had, it said there was a rapid increase in the hepatic glycogen concentrations after oral galactose. I am pretty sure milk and cheese have the same protein type since they both come from the same source. Depending on the milk and cheese, milk will usually have higher amounts of carbs, low amount of fat and cheese will have higher amounts of fat, low amount of carbs. So I don't know why cheese and milk would have such a different Insulin score. Maybe because of the way galactose is metabolized, maybe protein, maybe the fat, maybe all of them. I'm not sure.
