Common pet food protein sources include meat, fish, and some plant ingredients, such as corn gluten and soybean meal.

Protein has many functions in the body, but is best known for supplying amino acids, or protein subunits, to build hair, skin, nails, muscles, tendons, ligaments, and cartilage. Protein also plays a main role in hormone production.

Dogs, best fed as carnivores, and cats, true carnivores, require essential amino acids, such as taurine for cats, that are not all found in single plant protein sources such as soybean meal.

Common carbohydrate sources are plants and grains. Carbohydrates, also categorised as starches (sugars) and fibres, provide energy and bulk, respectively.

Starches are made up of various types of sugar, such as glucose or fructose. Sugar can be easily converted by the dog or cat through digestion into usable energy.

Fiber may or may not be fermented or broken down into short-chain fatty acids by bacteria in a dog or cat’s intestines. Highly fermentable fiber sources, such as vegetable gums, provide high amounts of short-chain fatty acids. Moderately fermentable fibers, such as beet pulp, provide short-chain fatty acids and bulk for moving waste. Slightly fermentable fibers, such as cellulose, provide mainly bulk for moving waste through the digestive tract and only a few short-chain fatty acids.

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

Fat, for all its bad press, fulfils many vital body functions. Animal cell membranes are made of fat. Fat is also responsible for helping maintain body temperature, controlling inflammation, and more. Fat is the primary form of stored energy in the body providing twice as much energy as carbohydrates or proteins.

Fats also provide the important fat subunits, omega-6 and omega-3 fatty acids. Omega-6 fatty acids are essential for maintenance of skin and coat and proper membrane structure. Omega-3 fatty acids have been shown to be important in blood clotting and decreasing inflammation.

Vitamins are responsible for aiding functions such as bone growth, blood clotting, energy production, and oxidant protection.

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.
