Matthew is a 16-year-old male who has lost 20 pounds in the last few months because it seems that everything he eats disagrees with him. He used to love pizza, but now suffers from bloating, flatulence and diarrhea whenever he eats it. Hot dogs and even ranch dressing elicit the same symptoms. He can no longer tolerate milk. His mother is concerned because he seems pale and tired all the time and no longer enjoys playing basketball at the park with his brother. She makes an appointment with the family doctor who runs a series of tests. The results show that Matthew has Celiac disease and is now also anemic and lactose-intolerant.

Question 1: Explain to Matthew what causes Celiac disease, how it’s diagnosed, including what those results would show, and how this disease is treated. You will need to defend your answer using specific facts, data, and other information drawn from the textbook and at least one other supplemental source.

John is a sedentary 60-year-old male who wants to lose 15 pounds. His usual diet is moderate in protein, some vegetables like potatoes and carrots, and whole grains and cereals. He’s decided that to lose weight, he’ll cut down on carbohydrates in his diet, and increase the protein content. However, John doesn’t want to give up his Starbuck’s caramel latte in the morning, so the coffee and two boiled eggs are his usual breakfast. His favorite lunch is a cheese burger, sans bun, with two slices of tomato and half of a small order of French fries. For dinner, he usually has a chicken breast with a small side salad. John is losing weight, but he’s now experiencing constipation and severe cramping.

Question 2: Analyze John’s current diet and explain how it can affect his GI microbiome and overall GI tract health. Discuss in your answer some dietary components promote the growth of beneficial GI tract bacteria and the benefits these bacteria convey. Support your answer with data, facts, key terminology, specific examples and other information drawn from the textbook and at least one other supplemental source.
