Choice A rationale:

While some individuals with Crohn's disease may find that avoiding gluten improves their symptoms, this is not a universal recommendation.

Gluten restriction is more often indicated for those with celiac disease or gluten sensitivity.

It's important to individualize dietary recommendations based on personal triggers and sensitivities.

Choice B rationale:

An elimination diet is a systematic approach to identifying foods that may trigger or worsen Crohn's disease symptoms.

It involves removing certain foods from the diet for a period of time, typically 2-4 weeks, and then gradually reintroducing them one at a time to observe any reactions.

This process can help individuals pinpoint specific foods that contribute to their symptoms and make informed dietary choices to manage their condition.

Choice C rationale:

There is no evidence to support a general restriction of calcium and iron in individuals with Crohn's disease.

In fact, these nutrients are essential for overall health and should be consumed in adequate amounts unless a specific deficiency or intolerance is identified.

Restriction of these nutrients could lead to nutritional deficiencies.

Choice D rationale:

Fluid restriction is not a primary dietary limitation for individuals with Crohn's disease.

Maintaining adequate hydration is crucial for overall health, especially during flares when fluid loss through diarrhea may be increased.

Restricting fluids could potentially lead to dehydration and electrolyte imbalances.
