Review of Hill's Science Diet Optimal Care Adult
Chicken Recipe

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 Optimal Care Adult Chicken Recipe is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for the maintenance of adult cats.

Ingredient Review

We'll begin this review of Hill's Science Diet Optimal Care Adult Chicken Recipe with a detailed discussion of the ingredients.

The first ingredient is chicken, which is an excellent source of protein and fat.

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 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.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Optimal Care Adult 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 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.

The next ingredient is brown rice. Brown rice is naturally rich in fiber and various minerals including manganese, phosphorus, and magnesium. Relative to other grains, brown rice is easy to digest.

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 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.

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 potassium chloride. Potassium chloride is a potassium supplement.

Our next ingredient 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.

soybean oil is the next ingredient in this recipe. 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.

Next on the list is iodized salt. Iodized salt is simply table salt mixed with very small amounts of iodine-containing salt. Iodine is an important natural element required by cats to maintain good health.

The next ingredient in this recipe is choline chloride. Choline chloride is member of the B-vitamin complex (vitamin B4).

Next we have vitamin E supplement. Vitamin E is an essential vitamin required by cats.

The next ingredient is l-ascorbyl-2-polyphosphate, which is a feed-grade vitamin C supplement.

Then 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 Optimal Care Adult recipe are unlikely to affect the overall rating of the product.

Our analysis of the ingredients show that this product derives most of its protein from animal based sources. This is an excellent property because meat based protein contains all of the necessary amino acids required by cats. In our option, this is one of the most important properties to judge when reviewing pet food, therefore we believe this is an exceptional product in this regard.

Final Thoughts

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