Final answer:
The healthcare provider should advise the parents to "Be sure to read all food labels carefully," as this is the best way to avoid gluten, which is essential for managing celiac disease.
Step-by-step explanation:
When providing dietary counseling for the parents of a child diagnosed with celiac disease, the most accurate information to include in the teaching plan is: "Be sure to read all food labels carefully." This is because people with celiac disease must strictly avoid gluten, which is a protein found in wheat, barley, and rye. Gluten-containing foods, even in trace amounts, can cause damage to the lining of the small intestine in these individuals. Avoiding gluten will help prevent symptoms such as diarrhea, anemia, and malnutrition, and reduce the risk of long-term complications like osteoporosis and certain types of cancers.
Option A is incorrect as pasta products are typically made from wheat unless specified as gluten-free. Option B is incorrect because starchy vegetables like peas and potatoes do not contain gluten and are safe for individuals with celiac disease. Option C is not completely accurate; while wheat and barley should be avoided, most corn and rice do not contain gluten and are usually considered safe for people with celiac disease unless contaminated during processing.
