Does Soy Protein Concentrate contain any ingredients that might trigger similar symptoms to gluten in some people with celiac?

Soy protein concentrate can contain trace amounts of FODMAPs and other compounds that may cause digestive issues in sensitive individuals, though these reactions are different from true celiac responses to gluten. Some people with celiac disease may have cross-reactive antibodies to soy proteins, leading to similar symptoms.
