GLUTEN! Mechanisms of Celiac Disease and Gluten Sensitivity

The video explains the difference between celiac disease and gluten intolerance. It details the role of gluten, its components glutenin and gliadin, and how they affect the small intestine in celiac disease. The immune response involving macrophages, T cells, and antibodies is discussed. The video also clarifies that many who claim gluten intolerance may actually have a FODMAP intolerance, which involves intestinal bacteria and not the immune system.

What are the two main components of gluten?

• Glutenin and Gliadin

• Wheat and Barley

• Protein and Carbohydrate

• Starch and Fiber

Where does most of the nutrient absorption occur in the digestive system?

• Small Intestine

• Large Intestine

• Esophagus

• Stomach

What enzyme modifies gliadin peptides in the interstitium?

• Amylase

• Trypsin

• Transglutaminase

• Pepsin

What type of immune cell presents antigens to T cells in celiac disease?

• Neutrophils

• Macrophages

• B cells

• Basophils

What is the role of helper T cells in celiac disease?

• They digest gluten

• They initiate an immune response

• They transport nutrients

• They produce insulin

What is the primary cause of discomfort in people with FODMAP intolerance?

• Lack of enzymes

• Gas production by bacteria

• Viral infection

• Immune response

Which of the following is NOT a FODMAP?

• Oligosaccharides

• Proteins

• Disaccharides

• Monosaccharides

What is a common symptom of FODMAP intolerance?

• Headache

• Rash

• Diarrhea

• Fever

How does FODMAP intolerance differ from celiac disease?

• It causes skin reactions

• It is caused by gluten

• It involves the immune system

• It involves bacterial fermentation

Which part of the intestine is primarily affected by FODMAPs?

• Large intestine

• Stomach

• Small intestine

• Esophagus
