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 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 (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.
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 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.
Nutrients such as protein, fat, vitamins, and minerals are important players in the skin and coat health of dogs and cats. To understand their role, it is necessary to first understand skin and hair.
The purpose of skin and hair is to block things (such as water or heat) from leaving, or things (such as viruses and bacteria) from entering the body.
The hair coat is composed almost entirely of protein. If an animal's diet doesn't contain adequate protein quantity and quality, hair may fall out, or become dry, weak, and brittle.
Skin is made up of squamous cells, which are flat cells tightly packed together. These cells have tough membranes that are composed of proteins and fats. Without proper amounts of these nutrients, cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Proteins are found in both animal-based and plant-based ingredients. Animal-based proteins contain all the essential amino acids cats need, whereas plant-based proteins may contain only some essential amino acids. Cats need animal-based proteins to achieve optimal health.
Fats also can be found in both animal-based and plant-based ingredients, and they are incorporated into skin cells as fatty acids. There are two essential fatty acids for skin and coat health. Linoleic acid maintains skin and coat condition in dogs and cats. Without enough linoleic acid cats may experience dull, dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation. Cats also require arachidonic acid for normal skin and coat health.
Both of these essential fatty acids are omega-6 fatty acids and are found in animal tissues such as chicken fat. Linoleic acid is also found in some vegetable oils, such as corn and soybean oils. Most commercial cat diets contain more than adequate amounts of omega-6 fatty acids.
Because these fatty acids can be converted to compounds that increase susceptibility to skin inflammation, it is important to balance the amount of omega-6 fatty acids in the diet with omega-3 fatty acids, which do not reduce susceptibility to inflammation.
Omega-3 fatty acids are found in oils from fish and some plants (canola and flax).
IAMS™ research has found that combining fat sources in the diet at a ratio of five to 10 omega-6 fatty acids to one omega-3 fatty acid results in excellent skin and coat health.
Vitamins and minerals are essential for the development of healthy skin and hair coat. The best way to provide these nutrients is through a complete and balanced diet containing appropriate amounts of essential vitamins and minerals rather than through supplements.
Vitamin or Mineral | Important for Skin and Coat Health |
Vitamin A | Necessary for growth and repair of skin |
Vitamin E | Protects skin cells from oxidant damage |
Biotin | Aids in the utilization of protein |
Riboflavin (B2) | Necessary for fat and protein metabolism |
Zinc | Necessary for fat and protein metabolism |
Copper | Involved in tissue, pigment, and protein synthesis |
Diet is often believed to be a factor when changes in skin and coat condition are noticed. The most common causes of these changes, however, are season and life stage.
As cold weather approaches, most dogs and cats grow a thick coat to help keep heat in and cold air out. As the weather begins to warm up, they shed the thick, heavy coat.
Most kittens are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or lactating cats also may experience a change in coat condition or hair loss.
