Some sources of protein, called high-quality proteins, produce less waste than others. High-quality proteins come from meat, fish, poultry, and eggs. Getting most of your protein from these sources can reduce the amount of urea in your blood.
If you have lost kidney function, your kidneys may not be able to get rid of this urea normally. You may need to reduce the amount of protein you eat to avoid buildup of urea in your body. Protein is found in two types of foods:
In large amounts in foods from animal sources such as poultry, meat, seafood, eggs, milk, cheese and other dairy products.
In smaller amounts in foods from plant sources such as breads, cereals, other starches and grains, and vegetables and fruits.
While you may need to limit the amount of protein you eat, it is important that you eat the right amount of protein. This helps to keep your body healthy.
