As a Type I diabetic (43 years) and biopsy diagnosed celiac (1 year), I routinely measure my blood glucose level several times a day. Thus, I have an immediate monitor of carbohydrate (and protein I believe) metabolism and hence the preceding intestinal absorption. Blood sugar typically peaks 2 hours after a meal except for foods like legumes with so-called "low glycemic index". Following introduction of the gluten free diet, my insulin needs indeed rose and I've since regained all the lost weight. The question of interest to all celiacs is what is the effect of a single gluten challenge on nutrient absorption? I haven't consciously tried that experiment yet myself, but can relate an unexpected result from a brief period last year when I was eating Kellog's Corn FLakes perhaps every other day for breakfast. The "malt flavoring" therein has both corn and barley. Perhaps twice a week for a month, my blood sugar would plummet mid-morning so that I had to eat about half my breakfast again in carbohydrate to make it to lunch time. Strangely enough several of these occurred on days when my breakfast was gluten free. This kind of drop, not rise, 2 hours after a meal had never happened to me in the preceding 42 years of diabetes before celiac diagnosis. It was almost as if that small percentage of gluten in those breakfasts had managed to wipe out most of the potential nutrient absorption. Yet in a temporary way as everything then would be normal perhaps until the aftermath of another gluten challenge. Are the intestines that sensitive to gluten? Perhaps other diabetics here have had similar experiences? Kemp Randolph [log in to unmask]
