The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains up to 73% 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 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 barley. Barley is 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 fourth ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The fifth ingredient is lamb, another quality, raw item inclusive of moisture.
The sixth ingredient is 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.
The seventh ingredient includes brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.
The eighth 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 product.
With four notable exceptions…
First, we find 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.
Next, apple pomace includes the pulpy solids that remain after pressing apples to extract the juice. It is most likely used here for its fiber content.
In addition, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.
And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.
Iams Naturals Dog Food Review
Judging by its ingredients alone, Iams Naturals 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.
As a group, the brand features an average protein content of 25% and a mean fat level of 14%. Together, these figures suggest a carbohydrate content of 53% for the overall product line.
And a fat-to-protein ratio of about 54%.
Below-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.
Even when you consider the protein-boosting effect of the peas, this looks like the profile of a kibble containing a moderate amount of meat.
Iams Naturals is a plant-based dry dog food using a moderate amount of named meat meals as its main sources of animal protein, thus earning the brand 3 stars.
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.
