Question 1

Celiac disease requires strict lifelong adherence to which dietary intervention?

Accepted Answer

Gluten-free diet (eliminating wheat, barley, and rye)

Answer

Celiac disease is an autoimmune disorder triggered by gluten; strict avoidance of wheat, barley, rye (and often oats due to cross-contamination) allows intestinal healing and symptom resolution.

Question 2

Which dietary approach is evidence-based for managing irritable bowel syndrome (IBS) symptoms?

Accepted Answer

Low-FODMAP diet (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols)

Answer

The low-FODMAP diet reduces fermentable carbohydrates that cause osmotic and fermentative symptoms in IBS, with 50-76% of patients experiencing significant symptom improvement.

Question 3

A patient with gout should be counseled to reduce intake of which substances that increase uric acid production?

Accepted Answer

High-purine foods (organ meats, shellfish) and alcohol (especially beer)

Answer

Purines are metabolized to uric acid; organ meats, shellfish, and alcohol (especially beer due to guanosine content) significantly increase serum urate and gout risk.

Question 4

In enteral nutrition, what does the term 'elemental formula' indicate?

Accepted Answer

Pre-digested formula with free amino acids, simple sugars, and minimal fat for impaired digestion

Answer

Elemental formulas contain hydrolyzed macronutrients (free amino acids, glucose polymers, MCT oil) requiring minimal digestion, intended for patients with severe malabsorption, short bowel syndrome, or pancreatic insufficiency.

Question 5

Which nutritional strategy is recommended to reduce the risk of neural tube defects during early pregnancy?

Accepted Answer

400-800 mcg of folic acid daily starting before conception and through the first trimester

Answer

Periconceptional folic acid supplementation (400-800 mcg/day) reduces the risk of neural tube defects (spina bifida, anencephaly) by 50-70% by supporting proper neural tube closure.
