Core Tip

Core tip: Food antigens have been indicated to participate in the etiopathogenesis of inflammatory bowel disease. However, their value is disputable, as some studies found that food immunoglobulin G (IgG) and E (IgE) antibodies can be expressed in healthy individuals. This study analyzed the levels of specific IgG and IgE antibodies against food antigens in inflammatory bowel disease patients and found that Crohn’s disease patients not only have higher prevalence of food-specific IgG, but also intolerance against rice, corn, tomato and soybean.
