The four objectives of proper nutrition.
The right diet should do more than provide calories for your cat. It should work synergistically with your cat's digestive, metabolic and immune systems to maximize her health and longevity.
Objective 1: Food as body development and maintenance.
This is what proteins, minerals, trace elements, vitamins and some lipids do.
Objective 2: Food as energy.
This is done by lipids and carbohydrates.
Objective 3: Food as prevention.
This is achieved with specific nutrients incorporated into food rations such as antioxidants and nutraceuticals. Nutrients can contribute to the prevention of renal infections or digestive disorders, for example, and have an anti-aging effect.
Objective 4: Food as medicine.
Certain nutrients added to food support the therapeutic or convalescence process, helping pets recover from a number of ailments.
