Review of Iams Proactive Health
This product is manufactured by Mars Petcare Inc..
According to our data, this Iams recipe provides complete & balanced nutrition for the maintenance of adult dogs. In other words, this formula is AAFCO approved.
Iams Proactive Health Adult Chunks 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 Iams Proactive Health Adult Chunks with a detailed discussion of the ingredients.
The first ingredient is chicken. Chicken is the most common meat ingredient used in dog food. It provides high-quality protein and fat. However, more than 60% of chicken is water.
The second ingredient is ground whole grain corn. Ground whole grain corn contains the entire corn kernel (the germ, bran, and endosperm). Corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in dog food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.
Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.
In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by dogs to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.
Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in dog food should certainly warrant further questioning.
The third ingredient is ground whole grain sorghum. Ground whole grain sorghum is a gluten-free carbohydrate source. This cereal grain also provides a modest amount of B vitamins and minerals such as magnesium, iron, phosphorus, and manganese.
The fourth ingredient is 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 fifth ingredient is dried beet pulp. Dried beet pulp is the by-product which remains once sugar has been extracted from sugar beets. The primary contribution of beet pulp is dietary fiber.
We'd also like to note that beet pulp is fairly controversial in pet food. Proponents claim that beet pulp can promote intestinal health and regulate blood sugar. However, opponents claim that beet pulp is an inexpensive filler.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Iams Proactive Health Adult Chunks 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 Iams recipe.
Next we have natural flavor. Natural flavoring does not contribute any nutritional value.
The next ingredient is chicken fat (preserved with mixed tocopherols). Chicken fat is a relatively good source of linoleic acid, which is an important essential fatty acid.
Then we have dried egg product. Dried 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.
Moving on, we have potassium chloride, which is a potassium supplement.
Moving on with this review, we have flaxseed. Flaxseeds are an outstanding source of omega-3 fatty acids and dietary fiber. They also provide a notable amount of protein, B vitamins, and various minerals.
The next ingredient in this review is caramel color. Caramel color is a concentrated form of caramel, a natural food colorant. Caramel color has been linked to cancer in laboratory animals. Since our pets do not care about food color, caramel color is an unnecessary addition with possible health risks.
Our next ingredient is salt. Salt is an important mineral for both humans and dogs. Depending on the quantity of salt used (which we cannot determine), salt may or may not be a nutritious addition in the recipe.
The remaining ingredients in this Iams Proactive Health recipe are unlikely to affect the overall rating of the product.
Our analysis of the ingredients show that this product derives most of its protein from animal based sources. This is an excellent property because meat based protein contains all of the necessary amino acids required by dogs. In our option, this is one of the most important properties to judge when reviewing pet food, therefore we believe this is an exceptional product in this regard.
In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
The official PawDiet rating for Iams Proactive Health Adult Chunks is 2.5 out of 5.
