Does anyone know of some actual studies that show the actual impacts on blood sugar of various foods (and possibly food combinations)? For example has there been any data collected from continuous monitors like the Libre Flash that can be amalgamated to provide real world data on the impact of various foods? I've been keeping a close eye on my own diet and blood glucose rises and have noted that many of the 'taboo' foods like potatoes don't seem to produce much of a response, particularly when eaten with other foods high in protein. For example I might only get a 0.5 mmol/l rise after eating a chicken casserole with 200 grams of chicken, and 100 grams each of potato and carrot and this also does not affect my ketone levels. Is this unusual? Is there some hard data on food vs blood glucose rise somewhere? If not could this forum possibly organise such a data collection?
