Note on the Orange Juice

I forgot to mention that, in that article by Welbourne (1995) [(http://hardcorephysiologyfun.blogspot.com/2009/02/glutamine-decreases-plasma-free-fatty.html)], the author used an orange juice drink with the glutamine. I'm not sure what the percent of the total amount of sugars in the orange juice is fructose, but I think it's high. Fructose has a low glycemic index of like 20 or something, and it doesn't produce much insulin release. That's probably one reason the orange juice didn't interfere with the effect. But the author would have been better off just being systematic about it and avoiding the confounding influence of "the orange juice." Glutamine, incidentally, can be gluconeogenic without elevating insulin levels, but I can't get into that now.
