The relationship between glycemic index, glycemic response, and disease outcomes is limited even in observational studies.

“It's called the relevance of glycemic index and glycemic load for body weight, diabetes and cardiovascular disease. And what's interesting is that they find that they say it is unlikely that the glycemic index of a food or a diet is linked to disease risk or health outcomes.”

“thus it is unlikely that the glycemic index of a food or diet is linked to disease risk or health outcomes”

“the strongest intervention studies typically find little relationship among glycemic index and glycemic response which is their synonym for glycemic load and physiologic measures of disease risk”

“even for observational studies the relationship between GI and gr and disease outcomes is limited”

“look at glycemic index right so what you're talking about there is glycemic index how quickly does your blood sugar spike it doesn't predict cardiovascular disease outcomes at all”
