Chronic Small Intestinal Disease Practice Test

In a diet-elimination approach, a novel protein is a source the patient hasn’t previously been exposed to, which helps avoid prior sensitization and makes it easier to tell whether the protein itself is related to symptoms. Lamb fits as a novel protein for many patients because beef, pork, and chicken are more commonly eaten in typical Western diets, so they are less likely to be considered novel. Using lamb provides a different protein source that is less likely to have preexisting sensitivities from frequent exposure, helping to identify if a patient’s symptoms improve when common proteins are avoided. The other options are all common dietary proteins, so they are less likely to be considered novel.
