What is the primary rationale for using hydrolyzed diets in suspected protein allergy cases?

• A. To break proteins into small peptides below immune detection threshold
• B. To preserve intact allergenic proteins
• C. To provide complete amino acids
• D. To avoid any carbohydrates

Answer: (A)

The main idea is to reduce the allergenicity of dietary proteins by breaking them into small fragments. Hydrolyzed diets degrade proteins into tiny peptides and free amino acids so the immune system has fewer recognizable epitopes to react to. Because the immune response in protein allergy often depends on intact or larger peptide portions triggering IgE and mast cell activation, smaller fragments are less likely to cause a reaction. Nutrition is still provided via amino acids and peptides, but the goal is to minimize immune recognition rather than simply preserving proteins or avoiding carbohydrates.
