Ingredient Review

We'll begin this review of Hill's Science Diet Grain Free Adult Chicken and Potato Recipe with a detailed discussion of the ingredients.

The first ingredient is chicken. Chicken is the most common meat ingredient used in dog food. It provides high-quality protein and fat. However, more than 60% of chicken is water.

The second ingredient is potato. Potatoes are commonly used in pet food as a gluten free carbohydrate source which also provides various vitamins, minerals, and antioxidants.

The third ingredient is yellow pea. Yellow peas are a good source of dietary fiber and minerals. They also provide a notable amount of plant based protein.

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 potato starch. Potato starch is a gluten-free ingredient extracted from potatoes. Unlike whole potatoes, the starch itself does not provide a notable amount of nutrition.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Grain Free Adult Chicken and Potato 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 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 next ingredient is chicken fat. Chicken fat is a relatively good source of linoleic acid, which is an important essential fatty acid.

Then 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, 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 with this review, we have flaxseed. Flaxseeds are an outstanding source of omega-3 fatty acids and dietary fiber. They also provide a notable amount of protein, B vitamins, and various minerals.

The next ingredient in this review 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.

Our next ingredient is lactic acid, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.

egg product is the next ingredient in this recipe. 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.

Next on the list 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 next ingredient in this recipe 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.

Next we have 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 dogs to maintain good health.

The next ingredient is potassium chloride, which is a potassium supplement.

Then we have choline chloride. Choline chloride is member of the B-vitamin complex (vitamin B4).

Moving on, we have green pea. Green peas are starchy members of the legume family. Other than carbohydrates, peas are notably high in plant based protein and various vitamins and minerals.

Moving on with this review, we have apple. Apples are high in dietary fiber and provide a modest amount of vitamins and minerals.

The next ingredient in this review is cranberry. Cranberries are rich in dietary fiber and provide a modest amount of vitamins such as vitamin C and minerals such as manganese.

Our next ingredient is vitamin E supplement. Vitamin E is an essential vitamin required by dogs.

l-ascorbyl-2-polyphosphate is the next ingredient in this recipe, which is a feed-grade vitamin C supplement.

Next on the list is 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 Grain Free Adult 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 dogs. This property is typically found in lower quality products.

Final Thoughts

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