Ingredient Review

We'll begin this review of Diamond Dry Dog Food Maintenance with a detailed discussion of the ingredients.

The first ingredient is chicken by-product meal. Chicken by-product meal is produced by cooking chicken by-products using a process called rendering. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, chicken by-products contain nearly all parts of chickens which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.

Like other meat by-products, chicken by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as chicken by-products, supply many important nutrients required by dogs.

The second ingredient is wheat flour. Wheat flour is produced by grinding uncooked wheat into a powder. In addition to dietary fiber, wheat flour provides various vitamins, minerals, and plant based protein.

Wheat is considered a controversial ingredient because of it's protein content. Plant based proteins degrade the overall protein quality in the product. In addition, many people believe wheat is 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 ground whole grain corn. Ground whole grain corn contains 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 fourth ingredient is rice bran. Rice grains can be divided into three components: bran, germ, and endosperm. The bran is the outer layer of the grain. The bran is an excellent fiber source, it also provide all three macronutrients (fat, protein, and carbohydrates) and various vitamins and minerals.

The fifth 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.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Diamond Dry Dog Food Maintenance 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 Diamond recipe.

Next we have chicken fat (preserved with mixed tocopherols). Chicken fat is typically collected while cooking chicken using a process called rendering. Chicken fat is a relatively high quality source of essential fatty acids. In particular, chicken fat is high in linoleic acid, an important omega-6 fatty acid.

The next ingredient is millet. Millet is a great source of gluten-free fiber. It's also an excellent source of B-vitamins, magnesium, manganese, and phosphorus.

Then we have ground white rice. Ground white rice is another name for white rice flour, which is a gluten free carbohydrate source.

Moving on, we have fish meal. Fish meal is defined by AAFCO as "the clean, dried, ground tissue of undecomposed whole fish or fish cutting, either or both, with or without the extraction of part of the oil." Since the specific type of fish is not mentioned, we cannot discuss any specific qualities of this ingredient. In general, anonymous ingredients are low quality inclusions when compared to ingredients such as tuna meal, salmon meal, catfish meal, etc.

Moving on with this review, we have 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.

The next ingredient in this review is 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.

Our next ingredient is natural chicken flavor. As the name implies, natural chicken flavor provides chicken flavor to the product. This particular flavor is derived from natural sources which may or may not include real chicken.

potassium chloride is the next ingredient in this recipe. Potassium chloride is a potassium supplement.

Next on the list is salt. Salt is an important mineral for both humans and dogs. Depending on the quantity of salt used (which we cannot determine), salt may or may not be a nutritious addition in the recipe.

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 dogs.

The remaining ingredients in this Diamond Dry Dog Food 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. 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 contains anonymous meat ingredients. These are not necessarily always negative; however, they are typically low quality and inexpensive additions. If the particular anonymous meat ingredient is controversial or low quality, it should have been discussed earlier in this review. Otherwise, it is safe to assume the anonymous meat ingredient is an acceptable addition.

The official PawDiet rating for Diamond Dry Dog Food Maintenance is 2.0 out of 5.
