Ingredient Analysis

The first ingredient in this dog food is chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1

Chicken is naturally rich in the ten essential amino acids required by a dog to sustain life.

The second ingredient is chicken broth. Broths are of only modest nutritional value. Yet because they add both flavor and moisture to a dog food, they are a common component in many canned products.

The third ingredient is chicken liver, an organ meat sourced from a named animal and thus considered a beneficial component.

The next ingredient is lamb. Lamb is considered “the clean flesh derived from slaughtered” lamb and associated with skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.2

Lamb is naturally rich in all ten essential amino acids required by a dog to sustain life.

The fifth ingredient is whitefish, a marine or freshwater species native to Canada and the California coast.

The next ingredient is spinach. Due to its exceptional vitamin and mineral content, spinach exhibits a remarkably high nutrient Completeness Score3 of 91.

The seventh ingredient is tomato, a nutrient rich vegetable consisting of about 72% carbohydrates.

The eighth ingredient includes carrots. Carrots are rich in beta-carotene, minerals and dietary fiber.

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 Nutro product.

With 7 notable exceptions

First, we find sunflower oil. Sunflower oil is nutritionally similar to safflower oil. Since these oils are high in omega-6 fatty acids and contain no omega-3’s, they’re considered less nutritious than canola or flaxseed oils.

Sunflower oil is notable for its resistance to heat damage during cooking.

There are several different types of sunflower oil, some better than others. Without knowing more, it’s impossible to judge the quality of this ingredient.

Next, we note the use of sodium hexametaphosphate, a man-made industrial polymer with no known nutritive value.

HMP is used in making soap, detergents, water treatment, metal finishing and most likely here to decrease tartar build-up on the teeth.

Although some might disagree, we’re of the opinion that food is not the place for tartar control chemicals or any other non-nutritive substances.

In addition, carrageenan is a gelatin-like thickening agent extracted from seaweed. Although carrageenan has been used as a food additive for hundreds of years, there appears to be some recent controversy regarding its long term biological safety.

The article, The Carrageenan Controversy, published in Scientific American, does a good job of addressing this topic.

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.

This recipe also includes 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.

However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.

Tomato pomace can also be a controversial ingredient. It is 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.

And lastly, with the exception of magnesium, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Chelated minerals are usually associated with higher quality dog foods.

Nutrient Analysis

Based on its ingredients alone, Nutro Ultra Grain-Free Dog Food in tubs appears to be an above-average moisture-rich product.

The dashboard displays a dry matter protein reading of 36%, a fat level of 23% and estimated carbohydrates of about 33%.

As a group, the brand features an average protein content of 41% and a mean fat level of 22%. Together, these figures suggest a carbohydrate content of 29% for the overall product line.

And a fat-to-protein ratio of about 54%.

Which means this Nutro product line contains…

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

Even when you consider the protein-boosting effect of the flaxseed and chia seed, this looks like the profile of a wet dog food containing a notable amount of meat..

Our Rating of Nutro Ultra Grain Free Dog Food Tubs

Nutro Ultra Grain-Free is a wet dog food using a notable amount of named meats as its dominant source of animal protein, thus earning the brand 4.5 stars.

Highly recommended.
