Review of Purina One SmartBlend
Sensitive Systems Formula
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.
Purina One SmartBlend Sensitive Systems Formula is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for the maintenance of adult dogs.
We'll begin this review of Purina One SmartBlend Sensitive Systems Formula with a detailed discussion of the ingredients.
The first ingredient is salmon. Although salmon is an excellent protein and omega-3 fatty acid source, raw salmon contains more than 60% moisture. After cooking, the relative meat contribution of salmon 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 second ingredient is rice flour. Rice flour is a gluten-free carbohydrate source. As long as the bran and germ of the grain are included in the flour, rice flour can provide a notable amount of fiber and nutrition. However, because the type of rice ("brown" or "white") is not specified, we cannot make this determination.
The third ingredient is pearled barley. Pearled barley is barley with the outer husk and bran layers removed. Similar to regular barley, pearled barley provides carbohydrates and dietary fiber. Pearled barley is however not as nutritious as regular whole grain barley.
The fourth ingredient is oatmeal. Oatmeal is simply coarsely ground oats and therefore contains the entire oat grain. As with regular oats, oatmeal is rich in dietary fiber, B vitamins, and various minerals.
The fifth ingredient is corn gluten meal. Corn gluten meal is a by-product from the production of various corn products (corn starch, corn syrup, etc). It's very high in protein (nearly 60% protein) and therefore can significant boost the protein content of the product. Because plant based proteins such as corn gluten meal are inferior to meat based proteins (lack many essential amino acids), they are not suitable substitutes.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Purina One SmartBlend Sensitive Systems Formula 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 chicken by-product meal. Chicken by-product meal is produced by cooking chicken by-products using a process called rendering. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, chicken by-products contain nearly all parts of chickens which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.
Like other meat by-products, chicken by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as chicken by-products, supply many important nutrients required by dogs.
The next ingredient is beef fat (preserved with mixed tocopherols). Fat is an important part of your dogs diet, beef fat in particular is a good source of essential fatty acids.
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 substantial 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.
In summary, we recognize that this product contains 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 Sensitive Systems Formula is 2.5 out of 5.
