CCS Dietary Requirements & Special Menus 3

Question 1

A food scientist is reformulating a recipe for guests with phenylketonuria (PKU). Which sweetener must be avoided because it metabolizes into phenylalanine?

Accepted Answer

Aspartame

Answer

Aspartame contains phenylalanine as one of its two amino acid components, making it dangerous for individuals with PKU who cannot metabolize phenylalanine.

Question 2

A hospital foodservice must provide a renal diet for a patient with chronic kidney disease. Which nutrient trio is MOST commonly restricted?

Accepted Answer

Potassium, phosphorus, and sodium

Answer

Renal diets restrict potassium, phosphorus, and sodium because impaired kidneys cannot adequately filter and excrete these electrolytes.

Question 3

Which technique is MOST effective for reducing the oxalate content of spinach to make it safer for guests prone to kidney stones?

Accepted Answer

Blanching and discarding the cooking water

Answer

Blanching spinach and discarding the water leaches water-soluble oxalates into the cooking liquid, significantly reducing oxalate content.

Question 4

A guest following a specific carbohydrate diet (SCD) for Crohn's disease asks about acceptable starches. Which is permitted?

Accepted Answer

Honey

Answer

The SCD allows honey (a monosaccharide) but prohibits all grains, most starches, and disaccharides including white rice, corn, and potato starch.

Question 5

For a menu targeting guests with histamine intolerance, which preparation method is BEST to minimize histamine accumulation in fish?

Accepted Answer

Immediate cooking or freezing after catch

Answer

Histamine forms rapidly in fish through bacterial decarboxylation; immediate cooking or freezing halts bacterial activity and prevents histamine accumulation.
