Maltodextrin is anathema for me (see my signature) which can be a problem sometimes since it is in so many processed foods and can even be found in vitamins and supplements.
Old Mike has researched this and here are some of the links he found. But for me what is most important is what I see with my own eyes, and maltodextrin has caused problems for me more than once. That said perhaps it will not be as bad for you since everyone is different.https://www.ncbi.nlm.nih.gov/pmc/articles/pmc4133521/
Maltodextrin, a polysaccharide derived from starch hydrolysis that is used as food additive, has been shown to markedly enhance AIEC biofilm formation and adhesion to intestinal epithelial cells and macrophages. Maltodextrin favors type 1 pili expression, which is required for biofilm formation and adhesion.https://health.usnews.com/health-news/news/articles/2012/05/21/could-compound-in-artificial-sweeteners-worsen-crohns-disease
Researchers then repeated the experiments, culturing E. coli with maltodextrin alone, and the same sticky biofilm formed. https://www.ncbi.nlm.nih.gov/pubmed/25000398
The dietary polysaccharide maltodextrin promotes Salmonella survival and mucosal colonization in mice.
