Egg Whites May Help Lower Phosphorus
Phosphorus levels declined in dialysis patients who ate egg whites instead of meat for one meal a day.
GRAPEVINE, TEX.Substituting egg whites for meat may help dialysis patients control phosphorus, according to a small study.
Lynn M. Taylor, MS, RD, and Ted Markewich, BA, of DaVita Carroll County Dialysis in suburban Maryland enrolled six men and seven women with serum phosphorus levels higher than 3.9 mg/dL. The first four weeks of the study consisted of data collection. Then, for one meal per day over the following six weeks, patients substituted eight ounces of pasteurized liquid egg whites for meat. The eight ounces of egg whites contained 24 grams of protein and 28 mg of phosphorus.
Twelve patients had a de-crease in phosphorus, the researchers reported here at the National Kidney Foundations 2008 Spring Clinical Meetings. Mean phosphorus levels declined significantly from 5.54 mg/dL at baseline to 4.63 mg/dL during the study. Mean patient-reported phosphorus intake also declined significantly, from 692 to 572 mg/day.
The diet did not affect albumin levels, which remained stable at a mean of about 4 mg/dL. Phosphorus binder intake also remained constant the mean number of pills taken by pa-tients was 6.63 at baseline and 6.42 during the study.
Pasteurized liquid egg whites are an effective component of the renal diet for lowering serum phosphorus while maintaining the albumin level, the authors concluded.
Does Vitamin D Increase Phosphorus Levels
Vitamin D functions by stimulating intestinal calcium and phosphorus absorption, by stimulating bone calcium mobilization, and by increasing renal reabsorption of calcium in the distal tubule.
What are the signs of phosphorus deficiency?
Symptoms of phosphorus deficiency include loss of appetite, anxiety, bone pain, fragile bones, stiff joints, fatigue, irregular breathing, irritability, numbness, weakness, and weight change. In children, decreased growth and poor bone and tooth development may occur.
What is the normal level of phosphorus in blood?
Theyll send the sample to a laboratory for analysis. What do the results mean? Serum phosphorus is measured in milligrams of phosphorus per deciliter of blood . According to Mayo Medical Laboratories, a normal range for adults is generally 2.5 to 4.5 mg/dL.
Whats the normal phosphorous level for a child?
The normal phosphorous levels in the blood for children are 4.5 to 6.5 mg/dL. As can be seen from the information given above, abnormal phosphorus levels in blood are a cause for concern for people who suffer from kidney disease and are on dialysis. Higher levels than the ones given above could result in death for dialysis patients.
How To Reduce Phosphorus In Food
Meat can be cut into pieces and boiled in water for 10-20 minutes. You can drain and use this meat to make a stew or sauce, or put it back in water to make boiled meat. This preserves the protein but the phosphorus is reduced by about half.
Egg whites are high in protein but do not contain phosphorus or cholesterol. Try using 1 whole egg and 1 egg white to make an omelet.
Meatballs can also be prepared by using egg whites. Egg whites whipped to stiffness are excellent for pies or meringues.

Foods High In Phosphorus
Phosphorus is found in most foods, including many healthful foods that are higher in protein. There are two forms of dietary phosphorus: “bound” phosphorus found naturally in foods and “inorganic” phosphorus found in food additives. About one half of our dietary phosphorus comes from naturally occurring sources like milk and dairy products, meat, poultry, fish, grains, and legumes . Nuts also provide significant phosphorus. Healthy individuals are encouraged to consume these foods in recommended amounts . People with the later stages of CKD may need to limit the number of servings of these foods. If you have chronic kidney disease, it is important to contact your healthcare professional to determine whether you need to restrict any of these foods.
Restaurant meals, fast foods, and convenience foods have added phosphorus. Phosphorus-containing additives are often added to foods and beverages to modify food texture or taste. Added phosphorus contributes about 500 mg/day to our diet . Some of the common phosphorus-containing additives include phosphoric acid and various forms of phosphates . Unfortunately, the phosphorus content of packaged food is not listed on the Nutrition Facts label. Instead, shoppers need to check the ingredient list to determine which packaged foods contain phosphorus-containing additives. Limiting foods with phosphorus-containing food additives is a great way of decreasing phosphorus intake.
How Can I Lower My Phosphorus Naturally
Here are seven methods to help control high levels of phosphorus: Reduce the amount of phosphorus you eat. Take phosphorus binders. Take vitamin D. Take a calcimimetic medicine. Stay on dialysis the entire time. Start an exercise program approved by a doctor. Get an operation to remove some of the parathyroid glands.

Are Omelets High In Phosphorus
One omelet made with a large egg contains 98.8 mg of phosphorus, which is 10% of your daily recommended need for this mineral.
This is a great amount, especially considering that a regular omelet isnt too caloric but still high in protein and other nutrients.
Omelets are also an easy way to add eggs to your diet if you dont like boiled eggs since you can add other ingredients, such as spices.
Whats more, many people make omelets with vegetables, cheese, and other ingredients.
Some of these foods are high in phosphorus, so you can further increase your intake of this mineral as well as other micronutrients and plant compounds.
In addition, adding vegetables to your omelet can help you feel fuller faster, preventing overeating and weight gain.

How Much Phosphorus Is In An Egg
Protein might be the nutrient that comes to mind when you think about eggs, but they also supply other vitamins and minerals you need on a daily basis. Phosphorus is just one of the key nutrients you’ll get when you eat a serving of eggs. They’re easy to prepare and are versatile enough to include in a wide variety of meals, making it simple to add them to your healthy eating plan.
Risks Side Effects And Interactions
What happens when phosphorus is too high? Although its rare, too much phosphate can be toxic and can cause symptoms like:
- Hardening of organs and soft tissue
- Interfering with the balance of iron, calcium, magnesium and zinc, which can have many negative impacts
- Athletes and others taking supplements that contain phosphate should only do so occasionally and with the guidance and direction of a health care provider
Phosphorus interacts with other minerals and certain medications too, so you shouldnt use high doses of supplements containing phosphorus without first talking with your health care provider. This is especially important among people with chronic kidney disease.
When someone has chronic kidney disease , the kidneys cannot remove phosphorus very well, which means it builds up and can pull calcium out of the bones. CKD patients are usually advised to adopt a low-phosphate diet for this reason.
This may involve reducing protein and dairy intake or eating a vegetable-based diet however it depends on the specific patient and situation.
Aim to maintain a proper balance of calcium-rich foods and foods high in phosphorus. An imbalance runs the risk of causing bone-related problems like osteoporosis, plus gum and teeth problems.
Research indicates that some other interactions of high levels of phosphorus, especially in relation to calcium, can include:

Sunflower And Pumpkin Seeds
Sunflower and pumpkin seeds also contain large amounts of phosphorus.
One ounce of roasted sunflower or pumpkin seeds contains roughly 45% of the RDI for phosphorus .
However, up to 80% of the phosphorus found in seeds is in a stored form called phytic acid, or phytate, which humans cannot digest .
Soaking seeds until they sprout can help break down phytic acid, releasing some of the phosphorus for absorption .
Pumpkin and sunflower seeds can be enjoyed as a snack, sprinkled on salads, blended into nut butters or used in pesto, and are a great alternative for people who are allergic to peanuts or tree nuts.
Summary Sunflower and pumpkin seeds contain large amounts of the storage form of phosphorus called phytic acid, which humans cant digest. Sprouting the seeds can help make the phosphorus available for absorption.
Signs Of Deficiency And Toxicity
A phosphorus deficiency is called hypophosphatemia, defined by blood levels that fall below the normal range. However, blood levels of phosphate do not necessarily show the total amount of phosphorus in the body, as most of it is stored in bones and teeth. The most common causes of deficiency are kidney problems or a condition called hyperparathyroidism, in which too much parathyroid hormone is released that causes phosphorus to exit the body through urine. Also, the overuse of aluminum-containing antacids can bind to phosphorus and increase the risk of a deficiency.
Symptoms appearing with a phosphorus deficiency:

Are Scrambled Eggs High In Phosphorus
Scrambled eggs made with two large eggs contain around 208 mg of phosphorus, making it a great source of this mineral.
Depending on how you prepared your scrambled eggs whether you add butter or oil or other ingredients the phosphorus content may increase along with the calories.
On the bright side, scrambled eggs are a very healthy and filling dish that provides you with various vitamins and minerals, including riboflavin, vitamin B12, and selenium.
Using Egg Whites To Keep Protein Up And Control Phosphorus
Lynn, a DaVita®renal dietitian in Maryland, conducted a study involving people on hemodialysis who substituted liquid egg whites for meat. She hoped this would help dialysis patients keep their protein or albumin levels up while controlling phosphorus levels and reducing the amount of phosphorus binders patients would have to take.
What is albumin?
Albumin is the most common protein found in the blood, providing the body with the protein needed to both maintain growth and repair tissues. During a dialysis treatment, the albumin in your blood also helps with fluid removal by pulling extra fluid from swollen tissues back into the blood, where it can then be removed by dialysis. Kidney Disease Outcomes Quality Initiative guidelines, from the National Kidney Foundation, recommends that a blood albumin level be 4.0 g/dl or higher. That is also DaVitas goal for all dialysis patients.
Where does albumin come from?
Albumin is found in foods that contain protein. Foods from animals contain the best sources of high quality protein. Lower quality protein comes from foods such as nuts, beans, vegetables and grain products. However, phosphorus is abundant in protein foods such as meats, dairy products, nuts and dried beans, and people with kidney disease need to follow a low-phosphorus kidney diet.
Inspiration for the egg white study
Lynn got the idea for the study from one of her patients on hemodialysis who consumed eight ounces of liquid pasteurized egg whites a day.

âPumpkin seeds are a powerful food that pack a nutrition punch,” says Tamburello. “In addition to providing a significant amount of phosphorus, pumpkin seeds are a source of plant-based protein which is especially important for non-meat eaters and have healthy fats, fiber, and tons of magnesium.” She recommends sprinkling pumpkin seeds on salads, roasted veggies, oatmeal, yogurt, smoothie bowls, or using them as a way to add delicious crunch to tacos.
The Connection Between Chronic Kidney Disease And Phosphorus In The Diet
Chronic kidney disease is a loss of kidney function over time. The kidneys function to remove waste products and excess water and minerals, such as sodium, potassium, and phosphorus from the body. As kidney function declines, the kidneys are unable to remove extra phosphorus from the body. Phosphorus levels in the blood may increase, especially in the later stages of the disease.
High blood levels of phosphorus may lead to adverse effects on bone, kidney, and heart health . When there is too much phosphorus in the blood, the body reacts by leaching calcium from the bones, which can lead to weak bones and the accumulation of calcium deposits elsewhere in the body. Weakened bones are prone to fracture. Calcium deposited in blood vessels can increase risk of heart disease and stroke.
If you are one of the 31 million people in the United States with CKD, you may need to limit your intake of phosphorus. Blood levels of phosphorus are critical to some people with CKD. For otherwise healthy people, a mildly elevated blood phosphorus level may increase risk for bone and heart disease .

How Can I Control My Phosphorus Level
You can keep you phosphorus level normal by understanding your diet and medications for phosphorus control. Phosphorus can be found in foods and is naturally found in protein-rich foods such as meats, poultry, fish, nuts, beans and dairy products. Phosphorus found in animal foods is absorbed more easily than phosphorus found in plant foods.
Phosphorus that has been added to food in the form of an additive or preservative is found in foods such as fast foods, ready to eat foods, canned and bottled drinks, enhanced meats, and most processed foods. Phosphorus from food additives is completely absorbed. Avoiding phosphorus additives can lower your intake of phosphorus. Phosphorus additives are found on the list of ingredients on the nutrition facts label. Look for PHOS to find phosphorus additives in the food.
Phosphorus additives found in foods include:
- Dicalcium phosphate
- Sodium tripolyphosphate
- Tetrasodium pyrophosphate
Your kidney dietitian and doctor will help you with this. Below is a list of foods high in phosphorous and lower phosphorus alternatives to enjoy:
