What To Eat And What Not To

Chronic Kidney Disease Supplements for improving kidney function and avoiding kidney failure

Food is not just the fuel that makes your body run. What you eat forms the building blocks for your cells. You really are what you eat. So, your food can, and does, affect your health. When you have CKD, one way to feel better and protect your kidneys is to take a fresh look at what you eat. See if you might want to make some changes to your diet. Your care team may give you some tips as well.

Foods that are close to nature like fruits, vegetables, nuts and seeds, beans and peas, whole grains, and lean meats are best for your body. Food that comes in a can, box, jar, or bag has been processed in a factory. Most processed foods have lots of chemicals, preservatives, and fillers . Some, like natural peanut butter, canned beans, or frozen vegetables, are good choices. How do you know which are good? READ LABELS. When a food has more than a few ingredients or a fresh food, like meat or fish, has an ingredient list at all be wary. Look for foods that have no more than five or six ingredients. You may want to make a fresh choice.

Most food cans in the U.S. are lined with bisphenol A . BPA has been linked with high blood pressure, diabetes, and obesity. Many canned foods tend to be very high in salt or sugar and highly processed, too. Glass jars or shelf safe cartons dont have BPA.

Talk To Your Doctor Before Taking Any Over

Because CKD can change the way your body processes certain substances, its important to talk to your doctor about any over-the-counter medication, vitamins, or supplements that youre takingwhether its something new or something youve been taking regularly. Certain medications and even herbal substances can be harmful at any stage of CKD. Talking to your doctor can help ensure that youre protecting your kidney health.

The Analysis: Vitamin D For Kidney Disease

Palmer, Strippoli and their colleagues searched medical databases fromJanuary 1966 through July 2007 to find published studies of vitamin D compoundsfor chronic kidney disease. They selected 76 that met their criteria forinclusion. In all, 3,667 participants were in these 76 studies.

When they pooled the results and analyzed them, the researchers found thatthe vitamin D compounds did not consistently reduce the parathyroid hormonelevels or reduce the risk of death, bone pain, blood vessel calcification, or other problems.

When they compared the established vitamin D sterols with placebo, thevitamin D treatments were associated with a 2.3 times higher risk of highcalcium levels and a nearly two times higher risk of high phosphate in theblood. And the treatment didnt consistently reduce the parathyroid hormonelevels.

Newer types of vitamin D treatment did not perform better.

The analysis is published in the Annals of Internal Medicine.

Chronic Kidney Disease Causes And Risk Factors

There are several causes and risk factors for chronic kidney disease, including:

  • Certain autoimmune conditions

The Centers for Disease Control and Prevention estimates that approximately half of individuals with severely reduced kidney function who are not receiving dialysis are unaware they have CKD. Specific urine and blood tests that assess kidney damage and filtration rate are used to identify CKD.

CKD has been associated with certain health complications, such as anemia, depression, stroke, increased risk of infections, and imbalanced mineral levels in the blood. Individuals with CKD are also at an increased risk of premature mortality associated with cardiovascular disease and cancer, making it critical to address CKD as early as possible.

Megadosing Vitamin C May Injure Kidneys

The megavitamin movement of the 1970s suggested that taking large doses of common vitamins would benefit health. Unfortunately, the alleged benefits may come at a price. A November 2017 update in GeneReviews states that megadosing vitamin C may lead to kidney failure. Surprisingly, even juicing with certain fruits and vegetables may cause this damage.

Many Americans use nutritional supplements to improve their health. As with vitamins, using these dietary aids increases the risk of organ damage. In fact, 1 in 12 people in the U.S. take supplements known to cause kidney damage, according to a March 15 report in the American Journal of Public Health.

Despite these risks, the Food and Drug Administration continues to leave nutritional supplements unregulated. Thus, people must take the initiative and educate themselves about the potential benefits and risks of dietary aids.

A September 2017 review in Food and Chemical Toxicology offers a starting point. This article provides a brief summary of kidney-damaging supplements. The authors suggest avoiding such dietary aids and specifically recommend avoiding excess doses of vitamins A, C and D.

Control Your Portion Sizes

Eating too much of anything, even healthy foods, can be a problem. The other part of a healthy eating plan is portion control, or watching how much you eat.

Good portion control is important in a kidney-friendly eating plan, because you may need to limit how much of certain things you eat and drink.

To help control your portion sizes:

  • For packaged foods, check the nutrition facts label to learn the serving size and how much of each nutrient is in one serving. Many packages have more than one serving. For example, a 20-ounce bottle of soda is really two-and-a-half servings.
  • For fresh foods that do not have nutrition facts labels, such as fruits and vegetables, ask your dietitian for a list of nutrition facts to measure the right portions.
  • Eat slowly and stop eating when you are full. It takes about 20 minutes for your stomach to tell your brain that you are full. If you eat too quickly, you may eat more than you need.
  • Avoid eating while doing something else, such as watching TV or driving. When you are distracted, you may not realize how much you have eaten.

What Supplements Are Hard On Kidneys

The most common form of kidney damage is called acute renal failure . ARF is caused by a lack of adequate calcium and phosphorus in the blood. , which is a type of acidosis, is the most serious form. It can cause kidney failure and death. The kidneys are the largest organ in your body. They are responsible for removing waste products from the body, including waste from your urine. In addition, they are also responsible with the production of urine, blood, and other bodily fluids. When the kidneys fail, the fluid in these fluids cant be removed. This can lead to dehydration, kidney stones, or even death if not treated quickly. If you have kidney disease, you may need to take medications to help you get rid of the excess fluid. You may also need dialysis to remove the waste product from blood and urine and to prevent kidney stone formation.

How Diet Can Impact Kidney Health

The kidneys are filled with tiny blood vessels that help filter waste and extra water from your blood and remove them from your body. If you have CKD, your kidneys cant filter blood as well as they should, causing excess waste to build up in your body.

Diabetes and hypertension are the two leading causes of kidney disease. High blood sugar levels in uncontrolled diabetes and high blood pressure can damage the kidneys blood vessels, leaving them unable do their job properly, says Krista Maruschak, RD, a registered dietitian with Cleveland Clinics Center for Human Nutrition.

Untreated or uncontrolled diabetes and high blood pressure can have a significant effect on the development of CKD over time, says Maruschak.

According to the Centers for Disease Control and Prevention, more than 10 percent of the U.S. population has diabetes and over a third of adults have prediabetes, while about half of American adults age 20 and over have hypertension. These individuals are also at an increased risk of developing CKD.

A healthy diet can help you prevent or manage conditions like diabetes and high blood pressure, in part by helping you to maintain a healthy weight, says Maruschak. In turn, this supports your kidney health.

As part of a kidney-friendly diet, you may also need to limit certain foods to help prevent further kidney damage.

A Brief Overview Of The Kidneys Role In Preventing Bone Loss

As your kidneys filter out toxins and excess acid from the blood, they also put a buffer or acid neutralizer back into the bloodstream in the form of bicarbonate. This shows how crucial it is for your system to be alkaline, and its also why the kidneys get overworked when, for example, you take a lot of medications and/or eat an acid-forming diet.

And just as there are certain foods that help cleanse and alkalize the body and ease the load on the kidneys, there are also foods that are not only acidic, but actually damage these important organs.

How To Leach Potassium From Fruits And Vegetables

If you can, swap canned fruits and vegetables for their fresh or frozen counterparts. The potassium in canned goods leaches into the water or juice in the can. If you use this juice in your meal or drink it, it can cause a spike in your potassium levels.

The juice usually has a high salt content, which will cause the body to hold onto water. This can lead to complications with your kidneys. This is also true of meat juice, so be sure to avoid this, too.

If you only have canned goods on hand, be sure to drain the juice and discard it. You should also rinse the canned food with water. This can reduce the amount of potassium you consume.

If youre cooking a dish that calls for a high-potassium vegetable and you dont wish to substitute, you can actually pull some of the potassium from the veggie.

The National Kidney Foundation advises the following approach to leaching potatoes, sweet potatoes, carrots, beets, winter squash, and rutabagas:

  • Peel the vegetable and place it in cold water so that it wont darken.
  • Slice the vegetable into 1/8-inch-thick parts.
  • Rinse it in warm water for a few seconds.
  • Soak the pieces for a minimum of two hours in warm water. Use 10 times the amount of water to the amount of vegetable. If you soak the vegetable for longer, be sure to change the water every four hours.
  • Rinse the vegetable under warm water again for a few seconds.
  • Cook the vegetable with five times the amount of water to the amount of vegetable.
