Answer:

a. People with celiac disease should include foods with dietary fiber such as beans, fruits, vegetables, brown rice, and quinoa.

e. Home-cooked meals are a good way to increase variety and reduce the cost of a gluten-free diet.

Explanation:

Celiac disease is an autoimmune disease, as stated above. This disease causes the defense cells of an organism to attack the stomach cells causing an inflammation that is extended and stimulated by the glutem. As a result, the individual has diarrhea, constipation, weight loss, anemia, a feeling of fullness, colic, abdominal discomfort, severe pain and may even develop ulcers and cancers.

Glutem is a protein found in wheat, barley and rye and for that reason, individuals with this disease should avoid these foods or foods derived from them. This type of diet should accompany the sick person for life and they should be encouraged to eat homemade foods that know the origin and composition. In addition, it is necessary that these people feed on dietary fibers, such as beans, fruits, vegetables, brown rice and quinoa.
