Review of Hill's Science Diet Indoor Age Defying Adult 11+
This product is manufactured by Hill's Pet Nutrition, Inc..
According to our data, this Hill's Science Diet recipe provides complete & balanced nutrition for the maintenance of adult cats. In other words, this formula is AAFCO approved.
Hill's Science Diet Indoor Age Defying Adult 11+ Chicken Recipe is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for the maintenance of adult cats.
We'll begin this review of Hill's Science Diet Indoor Age Defying Adult 11+ Chicken Recipe with a detailed discussion of the ingredients.
The first ingredient is chicken. Chicken is the most common meat ingredient used in cat food. It provides high-quality protein and fat. However, more than 60% of chicken is water.
The second ingredient is 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).
The third 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 fourth ingredient is 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 fifth 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.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Indoor Age Defying Adult 11+ Chicken Recipe 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 Science Diet recipe.
Next we have 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 next ingredient is 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.
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 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.
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 next ingredient in this review is fish oil. Fish oil is defined by AAFCO as "the oil from rendering whole fish or cannery waste." It is typically rich in omega-3 fatty acids and therefore a good fat source. However, the specific fish used to obtain the oil is not specified and therefore we cannot make any specific claims.
Our next ingredient is 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.
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 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.
Next we have taurine, which is an amino acid. As with other amino acids, taurine is required for the proper functioning of the body.
The next ingredient is vitamin E supplement. Vitamin E is an essential vitamin required by cats.
Then we have l-ascorbyl-2-polyphosphate, which is a feed-grade vitamin C supplement.
Moving on, we have niacin supplement. Niacin is also known as vitamin B3. It's an essential vitamin that is critical for the metabolism of nutrients and the well-being of the central nervous and GI systems.
The remaining ingredients in this Hill's Science Diet Indoor Age Defying Adult 11+ 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. This is an undesirable property because plant based protein often lacks many of the necessary amino acids required by cats. This property is typically found in lower quality products.
In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
The official PawDiet rating for Hill's Science Diet Indoor Age Defying Adult 11+ Chicken Recipe is 1.0 out of 5.
