I know - it is so frustrating! These harmful ingredients seem to be put in so many foods! One time I had a salad thinking it was healthy and was confused why I felt so sick the next day. Then, I realized the dressing had carrageenan AND xanathan gum in it. Those ingredients give me (and seems like most UCers) absolute hell.
You pointed out a very good one in maltodextrin and so I have been going back and looking to see which of my foods have that ingredient because I think that one also causes bleeding for me but I may have not realized it.
Do you have any issues with soy lecithin?
Maltodextrin is so frustrating for me because it is in so many vitamins and supplements, and I take tons of supplements. I know it can only be inside those capsules in minute quantities but it really makes a difference for me. So I have to carefully inspect labels.
Lecithin or phosphatidylcholine (PPC) was originally extracted from egg yolks and is used as an emulsifier in cooking and as a food supplement to lower cholesterol.
I used to take PPC to lower cholesterol and later for my UC and it seemed to halp for the first couple of years. Then all of a sudden it made things worse. Maybe my body chemistry changed or perhaps it might be that phosphatidylcholine is no longer derived from egg yolks but from soybeans, and about
95 percent of soy is GMO saturated with Roundup (glyphosate).
