DO WE NEED AN INSULIN INDEX OF FOODS?
If you asked me this question 10 years ago, I would have said no because knowledge of the GI and GL appeared to be sufficient to predict the insulin response. My PhD student at the time, Jiansong (Jason) Bao had proved this in an elegant study involving 121 single foods and 13 mixed meals (1).…
