Which of the following is listed as an example of a hydrolyzed diet?

• A. Hill's z/d, Purina HA, Royal Canin HP
• B. Hill's i/d, Purina Pro Plan Sensitive, Royal Canin Gastrointestinal
• C. Purina One Sensitive, Hill's z/d, Royal Canin Gastrointestinal
• D. Hill's z/d, Purina HA, Royal Canin Gastrointestinal HP

Answer: (A)

Hydrolyzed diets use proteins that have been broken down into much smaller pieces, so they’re less likely to be recognized as allergens by the immune system. This makes them useful when trying to manage suspected adverse food reactions or protein-triggered GI issues. The three diets listed as examples are all formulated with hydrolyzed protein sources: Hill’s z/d, Purina HA (hypoallergenic), and Royal Canin HP. Because they rely on hydrolyzed proteins, they’re designed to minimize immune reactivity and are commonly used in diagnostic elimination trials or ongoing management of suspected protein allergies. Other options described in the choices typically use intact or standard protein blends rather than hydrolyzed proteins, so they don’t fit the category of hydrolyzed diets.
