Thank you for that link. That study period of 5 weeks is not nearly enough to evaluate high versus low glycemic index diets upon metabolic syndrome. All the study showed was no acute impacts (good to know, but not conclusive enough for prescriptive direction). After finding that out from the study linked to, I tried to find a study that tracked glycemic index in meals of participants over 1-5 years, but couldn't come up with any, so if you know of any to link to, I would really appreciate it.
