Renal Nutrition can be defined as a diet recommended in chronic renal failure and which is intended to regulate the consumption of protein, potassium, sodium, phosphorus, and fluids.
Because the kidneys of individuals on dialysis are incapable of coping with excess fluid and other metabolic wastes, it is vital that the nutrient content of foods consumed by these people is prudently composed. Individuals using dialysis often consume poor amounts of macronutrients, fluids, and important micronutrients. Evidence suggests that the build-up of toxins that can occur with renal failure can also suppress the appetite. As a result, people being treated with dialysis frequently reduce the quantity of food they consume.
Metabolism
Metabolism is the chemical reactions involved in maintaining the dwelling state of the cells and the organism. Metabolism can be fairly divided into classes,
Catabolism - the breakdown of molecules to acquire energy
Anabolism - the synthesis of all compounds needed by the cells.
