Review of Hill's Prescription Diet Digestive/Weight Management w/d
This product is manufactured by Hill's Pet Nutrition, Inc..
According to our data, this Hill's Prescription Diet recipe provides complete & balanced nutrition for the maintenance of adult cats. In other words, this formula is AAFCO approved.
Unlike other AAFCO approved cat foods which rely in laboratory testing to substantiate nutritional adequacy, this recipe has undergone feeding trials. In the pet food industry, feeding trials are often considered to be the superior testing method.
Animal feeding tests using AAFCO procedures substantiate that Hill's Prescription Diet Digestive/Weight Management w/d With Chicken provides complete and balanced nutrition for the maintenance of adult cats.
We'll begin this review of Hill's Prescription Diet Digestive/Weight Management w/d With Chicken 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 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.
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 wheat gluten. Wheat gluten is the main protein of wheat. Although wheat gluten is mostly protein, wheat gluten is considered controversial because it significantly boosts the protein content of the product. This is undesirable because plant based protein does not provide the same amino acid profile as meat based protein.
The fifth 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.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Prescription Diet Digestive/Weight Management w/d With Chicken 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 chicken, which provides animal-based protein and important omega-6 fatty acids.
The next 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 cat 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 cats 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 cat food should certainly warrant further questioning.
Then we have whole grain wheat. Whole grain wheat contains the entire grain of wheat (the germ, bran, and endosperm). Wheat is the second most-produced cereal grain in the world (corn is the first). Although wheat is a controversial ingredient, it is not necessarily undesirable because it provides dietary fiber and many other nutrients. However, wheat contains a notable amount of plant based protein, which is inferior to meat based protein and therefore an undesirable substitution.
Wheat is also one of the most common ingredients to cause food allergies or intolerance. However, grains such as wheat are typically low offenders in comparison to certain protein sources (such as beef).
Moving on, we have natural pork flavor. As the name implies, natural pork flavor provides pork flavor to the product. This particular flavor is derived from natural sources which may or may not include real pork.
Moving on with this review, 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 in this review is lactic acid, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.
Our next 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.
potassium chloride is the next ingredient in this recipe, which is a potassium supplement.
Next on the list is choline chloride. Choline chloride is member of the B-vitamin complex (vitamin B4).
The next ingredient in this recipe 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 remaining ingredients in this Hill's Prescription Diet Digestive/Weight Management w/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.
In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
