The first ingredient in this dog food is beef. Although it’s a quality item, raw beef contains about 80% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.


After processing, this item would probably account for a smaller part of the total content of the finished product.


The second ingredient is lamb meal. Lamb meal is considered a meat concentrate and contains nearly 300% more protein than fresh lamb.


The third ingredient is sweet potato. Sweet potatoes are a gluten-free source of complex carbohydrates in a dog food. They are naturally rich in dietary fiber and beta carotene.


The fourth ingredient includes peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.


However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.


The fifth ingredient includes garbanzo beans, also known as chickpeas. Like peas, bean and lentils, the chickpea is a nutritious member of the fiber-rich legume (pulse) family of vegetables.


Garbanzos contain about 22% protein, something which must be considered when evaluating the total protein reported in this food.


The sixth ingredient is pea flour, a powder made from roasted yellow peas. Pea flour contains as much as 25% protein, a factor that must be considered when judging the meat content of this dog food.


The seventh ingredient is canola oil. Unfortunately, canola can be a controversial item. That’s because it can sometimes (but not always) be derived from genetically modified rapeseed.


Yet others cite the fact canola oil can be a significant source of essential omega-3 fatty acids.


In any case, plant-based oils like canola are less biologically availableto a dog than fish oil as a source of quality omega-3 fats.


The eighth ingredient 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 ninth 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.


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 four notable exceptions


First, flaxseed is 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 fish meal, another protein-rich meat concentrate.


Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.1


Unfortunately, this particular item is anonymous. Because various fish contain different types of fats, we would have preferred to have known the source species.


In addition, chicory root 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.


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 Naturals Grain Free Dog Food
The Bottom Line


Judging by its ingredients alone, Diamond Naturals Grain Free Dog Food looks like an above-average dry product.


But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.


The dashboard displays a dry matter protein reading of 27%, a fat level of 16% and estimated carbohydrates of about 50%.


As a group, the brand features an average protein content of 27% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 50% for the overall product line.


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


Near-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.


When you consider the protein-boosting effect of the pea products, garbanzo beans, potato protein and flaxseed, this looks like the profile of a kibble containing just a moderate amount of meat.


Bottom line?


Diamond Naturals Grain Free is a plant-based dry dog food using a moderate amount of named meats as its main sources of animal protein, thus earning the brand 3.5 stars.


Recommended.


Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
