Diamond Logo

Diamond manufactures roughly 36 different dog food products. Each product utilizes a unique set of ingredients to achieve a desired nutritional profile.

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

As of right now, our records indicate that Diamond uses roughly 145 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 Diamond, these are the most common ingredients found within the first 5 dog food ingredients.

  1. chicken
  2. chicken meal
  3. whole grain brown rice
  4. cracked pearled barley
  5. grain sorghum

As you can see, the most common first ingredient in Diamond is chicken. The most common 2nd ingredient is chicken meal, followed by whole grain brown rice, cracked pearled barley, and grain sorghum.

Artificial Food Coloring Dyes

Diamond does not use any artificial food coloring dyes. According to our records, none of the 36 Diamond dog foods contain artificial food dyes.

Artificial food coloring dyes are unnecessary and potentially harmful ingredients. In general, we not not recommend feeding any pet foods that contain artificial dyes.

In 2010, the CSPI raised serious concerns regarding the safety of many artificial dyes. Most of the studies referenced by the CSPI involved prolonged or excessive consumption. Since most dogs consume the same foods throughout their lives, concerns raised by the CSPI are alarming to say the least.

Animal By-Products

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

poultry by-product meal
1 Recipes

Poultry by-product meal is a controversial ingredient because the source animal is not specified. Anonymous ingredients such as poultry by-product meal are typically low-quality ingredients in comparison to named protein by-product meals (e.g. chicken by-product meal, turkey by-product meal, duck by-product meal).

The following recipes contain poultry by-product meal:

chicken by-product meal
5 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 Diamond.

Anonymous ingredients such as poultry by-product meal are typically low-quality ingredients in comparison to named protein by-product meals (e.g. chicken by-product meal, turkey by-product meal, duck by-product meal).

The following recipes contain poultry by-product meal:

meat meal
2 Recipes

Meat meal is produced by cooking meat using a process called rendering. The rendering process dramatically reduces the natural moisture of meat and thereby results in a highly condensed protein source.</p><p>This ingredient is marked controversial because the source animal for the meat is not specified. These type of anonymous ingredient are typically very low quality and certainly inexpensive additions. The most unpleasing property of this ingredient is that the meat source can contain any mammal, even dogs & cats.

The following recipes contain meat meal:

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 9 controversial ingredients inside Diamond products. These controversial ingredients are listed below. Click on each ingredient for more information.

white rice
1 Recipes

White rice is produced by removing the husk, germ, and bran of rice grains. Unlike brown rice which contains the bran and germ, white rice is nutritionally empty.

The following recipes contain white rice:

corn gluten meal
2 Recipes

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.

The following recipes contain corn gluten meal:

ground corn
2 Recipes

Ground 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 ground corn:

ground whole grain corn
4 Recipes

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.</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 whole grain corn:

canola oil (preserved with mixed tocopherols)
5 Recipes

Canola oil is a plant-derived oil from the seeds of canola plants. Although fat is an essential component of any diet, canola oil is controversial in pet food. Proponents claim that canola oil provides a better fat profile in comparison to other plant based oils. However, opponents claim that canola oil is typically produced with genetically modified rapeseed and that rapeseed oil has multiple adverse health affects.

The following recipes contain canola oil (preserved with mixed tocopherols):

tomato pomace
8 Recipes

Tomato pomace is a by-product of tomato manufacturing. It's considered a controversial ingredient because many people believe it is an inexpensive low quality filler. However, tomato pomace provides a notable amount of dietary fiber, B vitamins, Lycopene, and vitamin A. Although it is a very inexpensive ingredient, it is not nutritionally empty.

The following recipes contain tomato pomace:

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.
