Found this re. Maltodextrin, probably not great for celiacs even if it is gluten free..
‘maltodextrin can negatively impact gut health. For example, one studyshowed that maltodextrin can alter the composition of your gut bacteria in a way that makes you more susceptible to disease. It does this by suppressing the growth of the beneficial bacteria in your digestive system that support immune system function. The same study showed that maltodextrin can increase the growth of bad bacteria like E. coli in the gut. Overgrowths of bad bacteria are associated with autoimmune disorders like Crohn’s disease.
Another study acknowledges that maltodextrin impairs cellular antibacterial responses and suppresses intestinal antimicrobial defense mechanisms. The researchers postulate that maltodextrin contributes to intestinal inflammation which can lead to inflammatory bowel disease.’
‘despite being low in sugar, maltodextrin has a high Glycaemic Index (GI) rating (between 80 and 120), and causes blood sugar spikes just like glucose does. To put this into context, sugar’s glycaemic value is 65.2’
Tobacco is a nightshade that contains antihistamines.
So Celiac smokers may be self medicating with natural antihistamines which would lower effects of the immune system's response to gluten.
