The most common function of the kidneys is to remove waste products and extra fluids from your blood. When a person experiences kidney failure, these waste products and extra fluids remain in the blood. A special diet can help control the build-up of waste products and decrease the workload of kidneys. These diets usually manage the intake of protein, phosphorus, sodium, and fluids consumed. However, it is important to remember to get enough calories to maintain a healthy weight.

Protein

Protein is responsible for building muscles and repairing tissue, although, after the body uses it, a waste called urea is made. Large amounts of protein are found mostly in meat and dairy products. Plant sources such as breads, cereal, fruit& vegetables carry smaller amounts of protein.

Phosphorus

If the kidneys are too weak, they may not be able to remove this chemical element from the body. When phosphorus levels get too high, it may cause loss of calcium from the bones, resulting in them to be fragile and weak. Those who have been diagnosed with kidney failure may want to avoid eating foods with high amounts of phosphorus such as dairy products, beans, peas, nuts/ peanuts as well as beer, and soft drinks.

Sodium

Sodium levels are required to be limited because high blood pressure, kidney disease and sodium are often related. The highest levels are in table salts, snack foods, any type of fast food, and non perishable foods. Smoked and cured foods such as ham and bacon also contain high levels of sodium; therefore it is best to avoid eating any of these foods.

Calories

Since calories give the body the energy it needs to be active during the day, it is vital to increase the amount consumed while being cautious not to eat anything outside the recommended diet. Some ways to increase calories are to raise saturated fats such as vegetable oils (made with corn, cottonseed, safflower, soybean, or sunflower oils), olive oil and mayonnaise type salad dressings. Try to eat sugar or sweets such as hard candy, gum drops, jelly beans, marshmallows, honey, jam, and jelly. Also use canned or frozen fruits in heavy syrup.

In addition, it is important to keep the kidneys from overworking; which is why it is crucial to only drink when thirsty. Remember to brush your teeth four times a day so that your mouth is dry less often. You can also suck on a lemon wedge or suck on small pieces of ice. Try chewing sugarless gum, or sugarless candy. Another tip is to have one specific container to drink from to keep track of the amount consumed.
