Purina One Dog Food Ingredients

Purina One Logo

Purina One manufactures roughly 40 different dog food products. Each product utilizes a unique set of ingredients to achieve a desired nutritional profile.

In this article, we'll explore Purina One ingredients and answer many of the most common questions.

As of right now, our records indicate that Purina One uses roughly 132 different ingredients.

First 5 Ingredients

Dog food ingredients in the United States are listed in descending order of pre-cooked weight. The first 5 ingredients typically constitute a significant portion of the recipe.

For Purina One, these are the most common ingredients found within the first 5 dog food ingredients.

  1. chicken
  2. rice flour
  3. chicken
  4. liver
  5. pork lung

As you can see, the most common first ingredient in Purina One is chicken. The most common 2nd ingredient is rice flour, followed by chicken, liver, and pork lung.

Artificial Food Coloring Dyes

Our records indicate that Purina One does use artificial food coloring dyes. More specifically, we've identified 1 artificial food dye used by Purina One.

Although these food dyes are classified as Generally Recognized As Safe (GRAS) by the FDA, we recommend avoiding them when possible.

According to the Center For Research In The Public Interest (CSPI), there are many potential health risks associated with the consumption of artificial food coloring dyes.

Given that most pets consume the same products for prolonged periods of time, these concerns should be taken seriously. In general, we recommend pet owners avoid feeding products which contain artificial food coloring dyes.

For more information regarding the CSPI's findings, read our artificial food coloring article.

added color
2 Recipes

The ingredient "added color" is ambiguous and may include various artificial dyes. Most artificial dyes have been linked to various chronic diseases.

The following recipes contain added color:

Animal By-Products

Purina One does indeed use animal by-products. More specifically, 2 animal by-product ingredients were found during our analysis of Purina One dog food ingredients.

According to AAFCO, by-products are defined as the non-rendered, clean parts, other than meat, derived from slaughtered mammals. In other words, animal by-products are the leftover ingredients that humans typically do not consume (lung, heart, tongue, stomach, intestine, blood, etc).

Many consumers have equated animal by-products with slaughterhouse waste. Animal by-products are still very controversial. Most premium brands have abandoned them in favor of specific named organ ingredients (duck liver, chicken heart, etc).

If you must feed a product with animal by-products, ensure that the specific animal source is specified. In other words, avoid ingredients such as meat by-products or poultry by-products.

meat by-products
3 Recipes

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.</p><p>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 following recipes contain meat by-products:

chicken by-product meal
11 Recipes

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.</p><p>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 following recipes contain chicken by-product meal:

Anonymous Meat Ingredients

Anonymous meats are animal-based ingredients which do not provide the source animal's name. These ingredients are controversial because they can come from almost any animal.

In addition, anonymous animal-based ingredients are very inexpensive and often the lowest quality meats that are still allowed to be used in pet food.

In general, we do not recommend feeding any products which contain anonymous meats. When in doubt, always contact the brand's customer service desk for further clarification.

Unfortunately, we've identified 3 anonymous meat ingredients used by Purina One.

animal liver flavor
2 Recipes
fish meal
1 Recipes

Fish meal is defined by AAFCO as "the clean, dried, ground tissue of undecomposed whole fish or fish cutting, either or both, with or without the extraction of part of the oil." Since the specific type of fish is not mentioned, we cannot discuss any specific qualities of this ingredient. In general, anonymous ingredients are low quality inclusions when compared to ingredients such as tuna meal, salmon meal, catfish meal, etc.

The following recipes contain fish meal:

meat by-products

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.</p><p>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 following recipes contain meat by-products:

Controversial Ingredients

In most cases, ingredients which are given the controversial classification can be substituted with higher-quality alternatives. You should evaluate each controversial ingredient independently to see if there is truly a valid cause for concern.

Keep in mind, certain sacrifices often must be made to produce dog foods at a reasonable price. In general, the more expensive the product, the fewer controversial ingredients you'll find.

In our analysis, we've identified 15 controversial ingredients inside Purina One products. These controversial ingredients are listed below. Click on each ingredient for more information.

canola meal
4 Recipes

Canola meal is a high protein by-product of canola oil production. This ingredient is marked controversial because it may be derived from genetically modified rapeseed, which is associated with multiple adverse health affects.

The following recipes contain canola meal:

whole grain wheat
15 Recipes

Whole grain wheat contains the entire grain of wheat (the germ, bran, and endosperm). Wheat is the second most-produced cereal grain in the world (corn is the first). Although wheat is a controversial ingredient, it is not necessarily undesirable because it provides dietary fiber and many other nutrients. However, wheat contains a notable amount of plant based protein, which is inferior to meat based protein and therefore an undesirable substitution.</p><p>Wheat is also one of the most common ingredients to cause food allergies or intolerance. However, grains such as wheat are typically low offenders in comparison to certain protein sources (such as beef).

The following recipes contain whole grain wheat:

corn germ meal
7 Recipes

Corn germ meal is a high protein by-product of the oil extraction process from corn (maize). It's considered controversial because plant based protein does not contain all of the necessary amino acids required by dogs to sustain life. Therefore substituting corn germ meal protein for meat based protein is an unsuitable substitution and actually degrades the overall protein quality of the product.

The following recipes contain corn germ meal:

soybean protein concentrate
5 Recipes

Soybean protein concentrate is produced by removing the water soluble carbohydrates from soybeans. 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.

The following recipes contain soybean protein concentrate:

pea protein
2 Recipes

Pea protein is produced by removing the starchy parts of peas. Pea protein is considered controversial because it provides a substantial plant based protein boost. This boost is undesirable because plant based protein is typically lower in biological value when compared to meat based proteins.

The following recipes contain pea protein:

whole grain corn
15 Recipes

Whole grain corn is 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.</p><p>Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.</p><p>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.</p><p>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.</p><p>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 following recipes contain whole grain corn:

caramel color
21 Recipes

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.

The following recipes contain caramel color:

ground yellow corn
3 Recipes

Ground yellow 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.</p><p>Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.</p><p>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.</p><p>In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked.

The following recipes contain ground yellow corn:

liver
17 Recipes

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 following recipes contain liver:

meat by-products
3 Recipes

By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals."

The following recipes contain chicken by-product meal:

soybean protein isolate
1 Recipes

Soy protein isolate is a highly refined/purified form of soy bean protein. Roughly 90% of soy protein isolate is protein. 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.

The following recipes contain soybean protein isolate:

Potentially Harmful Ingredients

Harmful ingredients are those which have been linked to adverse health effects. In general, we do not recommend feeding any product which contains any harmful ingredients.

There are certain situations where these ingredients may be necessary. We always recommend contacting Purina One for further clarification regarding any harmful or controversial ingredient.

We have identified 3 harmful ingredients used in certain Purina One recipes. To learn more, click on the ingredient's name.

menadione sodium bisulfate complex
7 Recipes

Menadione sodium bisulfate complex is a synthetic version of vitamin K that has been linked to many health concerns. Research has suggested possible toxic reactions in liver cells and red blood cells among other serious problems. In fact, one large chemical supplier warns, "The substance is toxic to kidneys, lungs, liver, mucous membranes. Repeated or prolonged exposure to the substance can produce target organs damage."

The following recipes contain menadione sodium bisulfate complex:
