For more than 50 years, our nutritional and research teams have spent countless hours researching the nutritional needs of cats and dogs to understand the role nutrition plays in maintaining a healthy lifestyle. As such, each of our tailored diets includes at least 50 individual nutrients, adapted to a pet's unique needs.
At Royal Canin, we know that the value of ingredients in pet food is the nutrients they provide. That's why we take a nutrient-first approach to our unique diets.
In this approach, the nutritional needs of a pet are evaluated through detailed research and observation. An optimal diet profile is then determined for cats and dogs, based on both standard species guidelines and unique observations of the breed, age, lifestyle, sensitivities, and health status. From here, high-quality, highly digestible ingredients are sourced which can be combined to meet each tailored nutritional profile.
Relying on this approach, we are able to select high-quality nutrients from more sustainable sources with a lower carbon footprint. In doing so, we can choose ingredients with the least environmental and social impact while providing pets with nutrition of the highest quality, benefits, and safety.
Royal Canin's detailed approach to nutrition has four goals which underpin all of our nutritional developments:
Provide the energy the pet needs in the right amount and format through precise levels of
Meet the nutritional requirements of healthy physical development and maintenance through precise levels of
Support long-term health by considering common concerns including, for example, the effects of aging, digestive problems, and skin conditions through precise levels of
Very specific nutrients can be limited or added in certain formulations in order to help cats and dogs affected by particular health issues.
By meeting all of these goals, we are able to supply precise nutritional diets for the unique requirements of cats and dogs.
By recognizing the key benefits of each of these nutrients, you can make informed decisions about your pet's diet. At Royal Canin, we know that understanding what nutrients are important for your pet, and why, can be difficult. As such, we've broken down the five most important nutrients, where they can be sourced and the role they play in cat and dog nutrition, so that you can be confident in choosing the right food for your pet.
Protein is one of the main macronutrients in a pet's diet, alongside carbohydrates and fats. Cats and dogs require a lot of protein, as it is a source of energy, but is also key to healthy growth, healing, and gestation. Due to these roles, puppies and kittens, pregnant animals, and those suffering from certain illnesses may require more protein than healthy, adult pets.
It doesn’t matter if dietary protein comes from one source, or from multiple ingredients, as long as the total protein supplied in the diet provides all the necessary amino acids in the correct amounts.
Proteins are often large, complex molecules, consisting of a string of amino acids. They play critical roles in almost every aspect of the body, including:
Building and maintaining muscle mass
Producing enzymes which assist the many biochemical processes in the body
Supporting strong immunity, including the production of blood cells
Promoting healthy growth and development
Proteins from one ingredient may differ from another, based on; the length of the polypeptide chain, the individual amino acids that are in the chain, and how the chain folds. Sources of protein include:
Meat
Grains
Legumes
Vegetables
Carbohydrates is a term that covers molecules composed of carbon, oxygen, and hydrogen that have certain chemical characteristics in common.
Cats and dogs can live without carbohydrates in their food, as they synthesize some types of carbohydrates they need for the cells from amino acids. The intake of carbohydrates does, however, greatly improve the body’s functioning. Recent research has revealed that as they became domesticated, dogs have undergone genetic changes which mean they are able to thrive on diets with a greater proportion of carbohydrate.*

Using carbohydrates as an energy source means that the other calorie-containing macronutrients can be used in other ways. For example, protein and fat can be spared for other bodily functions such as growth or even wound healing, where needed. Other benefits of carbohydrates include:
Supporting the health and bacterial population of the digestive tract
Providing immediate energy to pets
Producing a satiety feeling in animals, which is particularly beneficial to pets at risk of becoming overweight
Carbohydrates are predominantly plant-based, with the exception of blood glucose, glycogen in the muscles and the liver, and milk lactose. Some examples of carbohydrate sources include:
Rice
Corn
Wheat
Barley
Potato
Milk (Although most cats and dogs do not digest lactose well)
Plants with fruit, berries, roots, or tubers
Lipids constitute a family of organic substances commonly known as fats. Fats are the benchmark energy source for dogs and cats, who oxidize them to extract the energy they need. A gram of lipids represents approximately 8.5 kcal of metabolizable energy, almost two and a half times more than a gram of carbohydrate or protein provides.
As with proteins and carbohydrates, in the correct proportions, lipids are an important source of energy for cats and dogs. Some fatty acids—termed "essential"—also have structural roles for the cell or act as precursors to specific hormones. Other benefits of lipids include:
Improving
palatability
Helping animals absorb important vitamins
Developing metabolic pathways and neurological systems Promoting healthy growth and development
Supporting immune functions and the inflammatory process which occurs in tissue injuries or infections
Dietary lipid sources are all foods rich in animal fats and vegetable fats. Some of these sources include:
Soy oil
Corn oil
Safflower oil
Butter
Animal Fat
Eggs
Poultry fat
Fish oil
The minerals that are present in high quantities (calcium, phosphorus, potassium, sodium, magnesium) are called macroelements. Those present in very low quantities—trace elements—represent a few milligrams/kilograms (or parts per million), but they are essential to the functioning of the body (e.g. iron, zinc, manganese, copper, iodine, selenium). An excess in mineral salts has an adverse effect on digestibility and may even produce effects contrary to expectations. This is why a precise, nutrient-based approach is vital when it comes to determining diets for cats and dogs.
Each mineral is involved in several different functions. For simplicity, we've outlined some of the main roles the most important minerals play in the body:
Ossification
Energy transfer
Cellular ionic balance
Sensory impulses
Synthesis of hemoglobin of red blood cells
Supporting the health of skin
Formation of cartilage and skin, and the synthesis of skin pigments
Functioning of the thyroid gland
Antioxidant functions
Minerals are provided by different ingredients, but they may also be included in the form of purified salts: iron sulfate, zinc oxide, manganese oxide, copper sulfate, sodium selenite, calcium iodate, and others.
Ingredients which are rich sources of minerals include:
Meat such as pork, duck, or chicken
Avocados
Fish
Wheat, cereal, grains
Peas, lentils, soy
Vitamins are split into two families: vitamins that are soluble in fats (liposoluble vitamins) and vitamins that are soluble in water (hydrosoluble vitamins). If they are consumed excessively, liposoluble vitamins accumulate in the body and can become toxic.
Each vitamin is involved in several different functions. As with minerals, we have highlighted some of the major roles in the body.
Calcium and phosphorus metabolism regulation
Protection against cell oxidation
Formation of blood cells and coagulation
Synthesis of hormones as part of the reproductive process
Regulate the growth of epidermis cells (outermost layer of skin) and the production of sebum
Neutralization of free radicals (antioxidative effect): For example, vitamin C permits the regeneration of vitamin E, a powerful natural antioxidant itself
Vitamins are provided in various ingredients and they can also be included in pure form. As naturally fragile substances, sensitive to light, heat, and oxidation, vitamins need to be protected during the cooking process.
Meat, kidneys, and liver
Fish oil
Eggs
Dairy products
Cereals
Vegetables
Citrus fruit
Berries
