What am I babbling about... Protein does <strong>not</strong> under any circumstances raise blood sugar levels. Of course not. However, what it does is cause a rise in blood insulin levels. Geez... (shaking my head at myself). Wait a second!

I was also rather surprised to read that protein could cause a rise in blood sugar, as I'm sure pretty much everyone would be... I mean, the conventional wisdom is that sugars do that, and not fats nor proteins, but it would really seem that a fast absorbing protein can also cause the same effect. The full text reads (and I translate from the original Finnish): "It has been noted in animal tests that a substantially larger amount of the nitrogen from hydrolyzed whey protein stays in the body of the animal than from whey protein concentrate (Poullain 1989).This is likely due to the fact that hydrolyzed whey is absorbed quickly, causing a rapid rise in blood amino acid levels. A large amount of amino acids in the blood in turn strengthens the release of anabolic hormones, such as insulin (Parcell et al. 2004), which increases the transport of amino acids into the muscle cells and accelerates the building of new proteins." The original studies cited are (I have not read these personally): Parcell AC, Drummond MJ, Christopherson ED, Hoyt GL, Cherry JA. Glycemic and insulinemic responses to protein supplements. J Am Diet Assoc. 2004 Dec;104(12):1800-4. Poullain MG, Cezard JP, Roger L, Mendy F. Effect of whey proteins, their oligopeptide hydrolysates and free amino acid mixtures on growth and nitrogen retention in fed and starved rats. JPEN J Parenter Enteral Nutr. 1989 Jul-Aug;13(4):382-6.

Do you have any reference for that? I'm curious, because it also contradicts everything I've heard before. Interesting news about the insulin producing effect of protein.
