If you suffer from kidney or liver disease, or if your body has unusually low metabolism due to illness, you will need to adapt your diet to lower your protein consumption. Though some protein is necessary to help your body grow and repair itself, eating too much protein can cause a buildup of urea---a waste product of proteins---and this places a burden on your kidneys. By following a low-protein diet, you can help to reduce the stress on the healthy parts of your kidneys by lowering the amount of urea that it must process. Many of your favorite recipes can be easily adapted to lower the amount of protein by simply substituting vegetables and grains in place of a portion or all of the meat in the recipes.
Significance
A low-protein diet is suggested for people suffering from liver or kidney dysfunction. Although an average of 40g to 60g of protein daily is necessary in the diet of most individuals, too much protein causes the organs to become overworked as they attempt to rid the body of excess urea, and for people with liver or kidney dysfunction, dealing with an excess of urea can overtax the healthy organs. A diet of 4 to 8 percent protein is frequently recommended for patients with kidney, liver or metabolism disorders or disease.
Low-Protein Recipe
Low-Protein Turkey Salad
In a large bowl, combine 1 1/2 cups of cooked turkey breast, skinless and chopped, 1 cup of diced celery, 3 cups of red delicious apples, chopped with skin intact, 1/4 cup of smashed pecans and 3 tbsp mayonnaise. Stir the ingredients well, then refrigerate in a covered container.
Prepare a cranberry French dressing by combining 1/2 cup of jellied cranberry sauce and 1/8 tsp each of paprika, dry mustard and black pepper. Use a whisk to stir, and add 1 tbsp vinegar and 2 tbsp vegetable oil a bit at a time, alternating between the two and ending with the vinegar.
Considerations
Compensate your diet for the loss in calories that can occur when lowering protein intake. Eat more healthy fats, including polyunsaturated vegetable oils, olive oil and mayonnaise. Eat fruits that have been preserved in heavy, sweet syrup, and eat hard candies throughout the day to help boost calories without increasing your protein consumption.
Be sure that your body is getting an adequate amount of protein. Have your physician perform routine blood work to check your protein and blood sugar levels after a few months on your low-protein diet. Too little protein in your diet could result in a loss of muscle and overall weakness and lethargy. Speak to a nutritionist about designing a diet plan that is right for you body's unique needs.
Low-Protein Foods
Most fruits and vegetables are low in protein, but there are exceptions. Some peas, beans and starchy vegetables, such as potatoes, can be extremely high in protein and should be avoided when you are on a low-protein diet. Fresh foods are higher in protein than frozen ones, so frozen versions of these foods might be one way of including them in your diet without overloading your body with urea.
Meat is very high in protein, measuring at about 10g of protein per ounce. An ounce of cheese may also contain up to 10g of protein and should be considered a "high-protein" food. Black-eyed peas, kidney beans and pinto beans are all high in protein, containing roughly 7g to 9g of protein per 1/4 cup serving. Pasta, peas, soy milk, potatoes and breads are relatively high in protein, as are white rice and corn. Small portions (1/4 to 2/3 cup) of these foods have between 3g to 7g of protein and should be eaten sparingly by those following a low-protein diet.
Supplements
Because your body may not receive some of the essential amino acids that it needs when you are on a low-protein diet, speak to your nutritionist or nephrologist about taking Keto acid supplements--a synthetic essential amino acid that will provide your body with the amino acids it requires, without overloading your kidneys.
