The first ingredient in this dog food lists potato. Potatoes can be considered a gluten-free source of digestible carbohydrates. Yet with the exception of perhaps their caloric content, potatoes are of only modest nutritional value to a dog.
The second 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 third item is potato protein, the dry residue remaining after removing the starchy part of a potato.
Even though it contains over 80% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.
The next ingredient is tomato pomace. Tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.
Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.
Just the same, there’s probably not enough tomato pomace here to make much of a difference.
The fifth ingredient is chicken fat. Chicken fat 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.
Next, 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.
After the natural flavor, we find menhaden oil. Menhaden are small ocean fish related to herring. Their oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids, two high quality fats boasting the highest bio-availability to both dogs and humans.
What’s more, in their mid-depth habitat, menhaden are not as likely to be exposed to mercury contamination as is typical with deep water species.
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 product.
With 3 notable exceptions…
First, we find chicory root. Chicory is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.
Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.
Next, we 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.
Since taurine deficiency appears to be more common in pets consuming grain-free diets, we view its presence in this recipe as a positive addition.
And lastly, this food contains 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.
Diamond Care Dog Food Review
Based on its ingredients alone, Diamond Care looks like an above-average dry dog food.
As a group, the brand features an average protein content of 26% and a mean fat level of 12%. Together, these figures suggest a carbohydrate content of 55% for the overall product line.
And a fat-to-protein ratio of about 45%.
Which means this Diamond product line contains…
Near-average protein. Below-average fat. And above-average carbs when compared to other dry dog foods.
When you consider the protein-boosting effect of the potato protein and flaxseed, this looks like the profile of a kibble containing a moderate amount of meat.
Diamond Care is a special purpose, grain-free dry dog food using a moderate amount of named meat or egg as its main source of animal protein, thus earning the brand 4 stars.
