Pathophysiology of Nutrition - High School Unit

Students begin by investigating the digestive system, enzyme function, nutrient absorption, and the specialized structure of the small intestine. They learn how digestive enzymes break down nutrients and why intestinal villi are essential for efficient absorption.

The second section explores lactose intolerance in depth. Students examine lactase deficiency, lactose digestion, bacterial fermentation, osmotic diarrhea, symptom development, hydrogen breath testing, and evidence-based dietary management strategies. Real-world patient scenarios encourage students to apply biological concepts to authentic health situations.

Students then investigate celiac disease as an autoimmune disorder. They analyze gluten, gliadin, immune activation, villous atrophy, nutrient malabsorption, diagnostic testing, and lifelong dietary treatment while comparing autoimmune diseases with enzyme deficiencies.

The unit concludes with comparative analyses, scientific case studies, inquiry-based investigations, modern diagrams, differentiated classroom activities, assessments, and complete answer keys that promote deep understanding of nutrition, physiology, and medicine.
