Review of Purina One SmartBlend
Lamb & Brown Rice Entree (Tender Cuts In Gravy)

This product is manufactured by Nestlé Purina Petcare.

According to our data, this Purina One recipe provides complete & balanced nutrition for the maintenance of adult dogs. In other words, this formula is AAFCO approved.

Unlike other AAFCO approved dog foods which rely in laboratory testing to substantiate nutritional adequacy, this recipe has undergone feeding trials. In the pet food industry, feeding trials are often considered to be the superior testing method.

Animal feeding tests using AAFCO procedures substantiate that Purina One SmartBlend Lamb & Brown Rice Entree (Tender Cuts In Gravy) provides complete and balanced nutrition for the maintenance of adult dogs.

Ingredient Review

We'll begin this review of Purina One SmartBlend Lamb & Brown Rice Entree (Tender Cuts In Gravy) with a detailed discussion of the ingredients.

The first ingredient is lamb broth. Lamb broth provides both flavor and moisture; however, as with other broths, lamb broth does not provide any notable nutritional contribution.

The second ingredient is turkey broth. As with other broths, turkey broth is a source of flavor and moisture.

The third ingredient is liver. Liver is a controversial ingredient because the source animal is not specified. Anonymous animal ingredients are typically very low quality and may contain almost any animal, including dogs and cats!

The fourth ingredient is lamb. Although lamb is an excellent protein source, raw lamb contains more than 60% moisture. After cooking, the relative meat contribution of lamb is dramatically reduced. Therefore, it's important to ensure that other meat sources are included within the first few ingredients to ensure the product derives most of its protein from meat.

The fifth ingredient is wheat gluten. Wheat gluten is the main protein of wheat. Although wheat gluten is mostly protein, wheat gluten is considered controversial because it significantly boosts the protein content of the product. This is undesirable because plant based protein does not provide the same amino acid profile as meat based protein.

Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Purina One SmartBlend Lamb & Brown Rice Entree (Tender Cuts In Gravy) are not as important as the first five ingredients.

However, collectively they still have a significant impact on the overall quality of the product. Therefore, we'll continue discussing the remaining ingredients in this Purina One recipe.

Next we have meat by-products. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, meat by-products contain nearly all parts of the animal which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.

This ingredient is marked controversial because the meat source is not identified. Anonymous ingredients such as meat by-products are typically very low quality additions. The most unpleasing property of this ingredient is that the animal source can contain any mammal, even dogs & cats.

The next ingredient is brown rice. Brown rice is naturally rich in fiber and various minerals including manganese, phosphorus, and magnesium. Relative to other grains, brown rice is easy to digest.

Then we have carrot. Carrots are naturally rich in many vitamins and minerals.

Moving on, we have soybean flour. Soybean flour contains more than 50% protein. Therefore, soybean can significantly boost the protein content of the product. The inclusion of non-meat protein typically degrades the overall quality of protein in the recipe. This degradation is due to the inferior amino acid profile of plant based proteins.

Moving on with this review, we have chicken, which provides animal-based protein and important omega-6 fatty acids.

The next ingredient in this review is modified corn starch. Modified corn starch is derived from the endosperm of the corn kernel. The modified term indicates that the corn starch has been treated or processed in order to expose or improve some property. Typically, corn starch is used as a binder in kibble.

Our next ingredient is spinach. Spinach is a nutritionally dense dark green vegetable rich in vitamins, minerals, and antioxidants.

egg product is the next ingredient in this recipe. Egg product consists of shell-free eggs which are easy to digest and contain high quality protein. Egg protein is often given the highest biological value (BV). The BV metric measures the usability of the ingredient's protein.

Next on the list is potassium chloride, which is a potassium supplement.

The remaining ingredients in this Purina One SmartBlend recipe are unlikely to affect the overall rating of the product.

Our analysis of the ingredients show that this product derives a considerable amount of protein from non-meat ingredients. This is an undesirable property because plant based protein often lacks many of the necessary amino acids required by dogs. This property is typically found in lower quality products.

Final Thoughts

In summary, we recognize that this product contains artificial colors and anonymous meat ingredients.

Although the FDA has approved the artificial colors used in this product, they are unnecessary and unhealthy additions. Long term exposure can have serious consequences. See our article on artificial food dyes for more information.

In regards to the anonymous meat ingredients, These are not necessarily always negative; however, they are typically low quality and inexpensive additions. If the particular anonymous meat ingredient is controversial or low quality, it should have been discussed earlier in this review. Otherwise, it is safe to assume the anonymous meat ingredient is an acceptable addition.

The official PawDiet rating for Purina One SmartBlend Lamb & Brown Rice Entree (Tender Cuts In Gravy) is 2.0 out of 5.
