Ingredients Analysis

The first ingredient in this dog food is beef meal. Beef meal is considered a meat concentrate and contains nearly 300% more protein than fresh beef.

The second is sorghum. Sorghum (milo) is a starchy cereal grain with a nutrient profile similar to corn.

Since it is gluten-free and boasts a smoother blood sugar behavior than other grains, sorghum may be considered an acceptable non-meat ingredient.

The third ingredient is ground white rice, another name for rice flour. Ground rice is made from either white or brown rice and is considered a gluten-free substitute for wheat flour.

The next ingredient is dried yeast, which can be a controversial item. Dried yeast contains about 45% protein and is rich in other healthy nutrients.

Fans believe yeast repels fleas and supports the immune system.

Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.

What’s more, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is something we’ve not been able to scientifically verify.

In any case, unless your dog is specifically allergic to it, we feel yeast should be considered a nutritious addition.

The fifth ingredient is egg product, an unspecified (wet or dry?) form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

The sixth ingredient is rice bran, a healthy by-product of milling whole grain rice. The bran is the fiber-rich outer layer of the grain containing starch, protein, fat as well as vitamins and minerals.

The next ingredient is barley, a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.

The eighth ingredient is chicken fat. This item is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.

Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.

The ninth ingredient is beet pulp. Beet pulp is a controversial ingredient, a high fiber by-product of sugar beet processing.

Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.

We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this Diamond Naturals product.

With six notable exceptions

First, we find flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

Next, we note the inclusion of chia seed, an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber and contain about 17% protein.

In addition, we find quinoa in this recipe. Quinoa (pronounced keen-wah) is not a true cereal grain but a plant prized for its gluten-free seeds.

Compared to most other grain-type ingredients, it is high in protein (about 12-18%), dietary fiber and other healthy nutrients.

Next, this recipe contains sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.

We also note the use of taurine, an important amino acid associated with the healthy function of heart muscle. Although taurine is not typically considered essential in canines, some dogs have been shown to be deficient in this critical nutrient.

And lastly, this food includes chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.

Nutrient Analysis

Based on its ingredients alone, Diamond Naturals Adult Dog Beef Meal & Rice Formula looks like an above-average dry product.

The dashboard displays a dry matter protein reading of 28%, a fat level of 17% and estimated carbohydrates of about 48%.

As a group, the brand features an average protein content of 28% and a mean fat level of 17%. Together, these figures suggest a carbohydrate content of 47% for the overall product line.

And a fat-to-protein ratio of about 58%.

Which means this Diamond Naturals product line contains…

Above-average protein. Near-average fat. And near-average carbs when compared to other dry dog foods.

Even when you consider the protein-boosting effect of the dried yeast, quinoa, flax and chia seeds, this looks like the profile of a kibble containing a notable amount of meat.
