Ingredient Review

We'll begin this review of Hill's Prescription Diet Digestive Care i/d Chicken 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 whole grain corn. Whole grain corn is the entire corn kernel (the germ, bran, and endosperm). Corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in dog food.

Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.

Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.

In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by dogs to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.

Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in dog food should certainly warrant further questioning.

The third ingredient is chicken meal. Chicken meal is produced by cooking chicken using a process called rendering. The rendering process dramatically reduces the natural moisture of chicken and thereby results in a highly condensed protein source.

The fourth ingredient is pea protein. Pea protein is produced by removing the starchy parts of peas. Pea protein is considered controversial because it provides a substantial plant based protein boost. This boost is undesirable because plant based protein is typically lower in biological value when compared to meat based proteins.

The fifth ingredient is egg product. Egg product consists of shell-free eggs which are easy to digest and contain high quality protein. Egg protein is often given the highest biological value (BV). The BV metric measures the usability of the ingredient's protein.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Prescription Diet Digestive Care i/d Chicken 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 pork fat. Pork fat is typically collected while cooking pork using a process called rendering. Pork fat is a relatively high quality source of essential fatty acids. In particular, pork fat is high in linoleic acid, an important omega-6 fatty acid.

The next ingredient is corn gluten meal. Corn gluten meal is a by-product from the production of various corn products (corn starch, corn syrup, etc). It's very high in protein (nearly 60% protein) and therefore can significant boost the protein content of the product. Because plant based proteins such as corn gluten meal are inferior to meat based proteins (lack many essential amino acids), they are not suitable substitutes.

Then we have 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.

Moving on, we have dried beet pulp. Dried beet pulp is the by-product which remains once sugar has been extracted from sugar beets. The primary contribution of beet pulp is dietary fiber.

We'd also like to note that beet pulp is fairly controversial in pet food. Proponents claim that beet pulp can promote intestinal health and regulate blood sugar. However, opponents claim that beet pulp is an inexpensive filler.

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

The remaining ingredients in this Hill's Prescription Diet Digestive Care i/d recipe are unlikely to affect the overall rating of the product.

Our analysis of the ingredients show that this product derives a considerable 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.
