Ingredient Review

We'll begin this review of Hill's Prescription Diet Skin/Food Sensitivities z/d Original Flavor with a detailed discussion of the ingredients.

The first ingredient is brewers rice. Brewer's rice is the small fragments of rice kernel that are separated from the larger kernels of milled rice. The fragments do not contain the same nutrition profile of the whole kernel and therefore brewer's rice is a lower quality grain. Brewer's rice is typically regarded as an inexpensive and low quality filler.

The second ingredient is hydrolyzed chicken liver. Chicken liver hydrolysate is produced by subjecting chicken liver to a processes called hydrolysis. In short, hydrolysis makes use of water to split chemical bonds. By doing this, amino acids from the protein source can be absorbed into your cats body quicker than the original intact protein source.

The third ingredient is powdered cellulose. Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.

The fourth ingredient is soybean oil. Soybean oil is an omega-6 fatty acid source. Unlike other oils (flax, canola, etc), soybean oil does not provide omega-3 fatty acids; However, the balancing omega-3 fatty acids are most likely supplied by another oil or fat source in the product.

The fifth ingredient is natural chicken liver flavor. As the name implies, natural chicken liver flavor provides chicken liver flavor to the product. This particular flavor is derived from natural sources which may or may not include real chicken liver.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Prescription Diet Skin/Food Sensitivities z/d Original Flavor are not as important as the first five ingredients.

However, collectively they still have a significant impact on the overall quality of the product. Therefore, we'll continue discussing the remaining ingredients in this Hill's Prescription Diet recipe.

Next we have lactic acid, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.

The next ingredient is calcium carbonate. Calcium carbonate is a naturally occurring mineral supplement. Although it's often used as a dietary calcium supplement, it can also be used as a preservative or color retainer.

Then we have calcium sulfate. Calcium sulfate is a food additive that helps control acidity levels and functions as a firming agent. It's not a desirable ingredient, but it is considered safe by the FDA in small quantities.

The remaining ingredients in this Hill's Prescription Diet Skin/Food Sensitivities z/d recipe are unlikely to affect the overall rating of the product.

Our analysis of the ingredients show that this product derives a substantial amount of protein from non-meat ingredients. Since this product is a prescription diet, this property may be required and therefore we cannot make any further statements.

Final Thoughts

In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
