Kidneys are very important in our body. These organs serve essential functions in our system. They are the natural filter of our blood, and they remove toxic wastes, which are diverted to the urinary bladder. The kidneys help to maintain the homeostasis of our system. Once these organs are afflicted with any kind of disease, it is already difficult to maintain a normal life. You can no longer do the usual things you enjoy. Your preferences of food are also limited. So what is the best renal diet suited for you?
Renal diet can assist in controlling the accumulation of waste products and fluid in the blood stream. This may also help in slowing down the deterioration of the kidneys. Your main goal in adhering to renal diet is to keep you healthy. A perfect renal diet includes controlling intake of fluids, potassium, phosphorus, and sodium.
Patients who are for dialysis are asked to reduce protein intake to slow the progression of the disease. This changes when the patient starts the dialysis treatment. Once the treatment begins, the patient would need more protein in their renal diet. Maybe you are wondering what types of foods are rich in protein.
As a matter of fact, protein can be found in two kinds of foods:
- In small quantity in foods from plant sources (breads, cereals, starches, etc.)
- In large amounts in foods from animal sources (poultry, milk, cheese, meat, eggs, etc.)
One common problem among patients who are on dialysis treatment is hyperkalemia or the increase level of potassium in the person’s body. That is why you have to limit your intake of potassium. Foods rich in potassium are banana, apricots, raisins, dried fruit mix, mixed nuts, baked potato with skin, roasted potatoes, boiled soy beans, whole-grain pasta, soy flour and many more!
Aside from potassium, patients should also control their intake of foods high in sodium or salt. This is still part of their renal diet. Sodium helps in controlling the fluid equilibrium inside their body. Patients should control eating snack foods, and any processed products. And if the patient happens to love “fast foods,” well not so good news for them since these types of foods is very high in salt or sodium.
Lastly, renal diets also suggest limiting fluid intake. Patients having a renal disease are very prone in fluid accumulation. Fluid restriction may differ from one patient to another. The amount of fluid allowed to take is determined through the patient’s pre and post dialysis weight, urine output and more. The nurse and the dietician will work hand on hand to advise you how much fluid you are allowed to drink.
