Understanding Common Ingredients and Nutrients in Cat Food

  • Share

Do you know what’s in your cat’s food? And more importantly, do you know how those nutrients affect your cat’s health, including their muscles, skin, coat and nails, digestion, bone growth and so much more?
 

As the old adage goes, “You are what you eat,” so it stands to reason that by feeding your cat high-quality ingredients, their overall health will be positively impacted.
 

So, what’s in your cat’s food? Simply put, cat food nutrients are divided into four subcategories: protein, carbohydrates, fats, and vitamins and minerals. Learn more about each of these — and how they can affect your cat’s health.

 

Protein in Cat Food

Protein is best known for supplying amino acids, or protein subunits, to build hair, skin, nails, muscles, tendons, ligaments and cartilage.
 

Common cat food protein sources include meat, chicken, fish and some plant ingredients like corn gluten and soybean meal.
 

Cats and kittens are true carnivores and need essential amino acids. One of these, taurine, is not found in plant protein sources such as soybean meal — which means your cat needs a protein source from meat to stay healthy.

 

Carbohydrates in Cat Food

Carbohydrates (also known as starches [sugars]) and fibers provide energy and bulk, respectively. Plants and grains like wheat and corn are common carbohydrate sources.
 

Starches are made up of various types of sugar, such as glucose or fructose. Through digestion, cats can easily convert sugar into usable energy.
 

Fiber provides bulk to move food through your cat’s gastrointestinal tract, aiding in healthy digestion. Some types of fiber, such as vegetable gums and beet pulp, are fermented by bacteria in your cat’s intestines, creating short-chain fatty acids that serve as an important source of energy for the cells lining your cat’s intestinal tract.

 

Fat in Cat Food

Though it sometimes gets a bad rap, fat fulfills many vital bodily functions. Fat helps your cat maintain their body temperature, control inflammation and more. It is the primary form of stored energy in the body, providing twice as much energy as carbohydrates or proteins.
 

Fats are found in meats, fish and plant oils, such as flax and vegetable oils.
 

Fats also provide omega-6 and omega-3 fatty acids, which are important fat subunits. Omega-6 fatty acids are essential for skin and coat maintenance and proper membrane structure. Omega-3 fatty acids have also been shown to affect coat quality and skin health.

 

Nutrition tip: All IAMS™ dry foods contain an optimal ratio of omega-6 and omega-3 fatty acids to help support a healthy skin and coat.

 

Vitamins and Minerals in Cat Food

Vitamins are responsible for promoting bone growth, blood clotting, energy production and oxidant protection in your cat.
 

Vitamins A, D, E and K require fat for absorption into the body, while vitamins such as the B-complex vitamins and vitamin C need water to be absorbed into the body.
 

Minerals provide skeletal support and aid in nerve transmission and muscle contractions.
 

Feeding your cat a high-quality, nutritionally complete diet is crucial. When choosing a cat food, make sure to read the label and look for optimal sources of protein, carbohydrates, fat, and vitamins and minerals. These building blocks will help ensure your cat lives a long and healthy life.

    Understanding Kitten Food Nutrition Labels

    • Share

    Confused by the ingredient list on your kitten’s food? You’re not alone. Marketing pet foods that have “human-grade ingredients” is becoming commonplace. While appealing to many pet owners, it is important to be aware that the term “human grade” has no legal definition and is used primarily for marketing purposes.

     

    Foods, typically meats, are labeled either as “edible” or “inedible, not for human consumption.” Once a food leaves the human food chain, even if it is of outstanding quality, it has to be labeled “inedible, not for human consumption.” Therefore, meats used in pet food must be labeled as “inedible,” regardless of the source or quality of the meat. The only way to make a pet food with ingredients deemed “edible” is to never let the meat leave the human food chain and actually manufacture the pet food in a human food facility and transport it using human food trucks. Therefore, advertising a product as containing “human-grade ingredients” is untrue if it is not manufactured in a human food facility. However, just because a pet food isn’t marketed as being “human grade” does not mean that the ingredients are poor quality.

     

    Here are some tips to help understand ingredient labels:

     

    • The ingredient list is not the only method you should use to select a pet food, because it doesn’t provide pet owners with enough information about the quality of the ingredients or the nutritional adequacy of the overall diet.
    • Instead of concentrating on ingredients, pet owners and veterinarians should look at the AAFCO nutritional adequacy statement and the quality control protocols of the manufacturer. For more information, see the World Small Animal Veterinary Association’s brochure “Selecting the Best Food for your Pet,” available at www.wsava.org/nutrition-toolkit.
    • The ingredient list may be arranged to make foods as appealing as possible to consumers by the order of the ingredients (e.g., having lamb first on the ingredient list) or inclusion of seemingly desirable ingredients in the diet, but often in such small amounts that they have little or no nutritional benefits.
    • Having more ingredients does not make a diet more nutritious.
