Suffering From Kidney Disease? Know Your Diet

Kidneys are the body organs that perform many important functions, including blood filtration, blood pressure regulation, electrolyte balancing, and urine production. However, some health disorders, such as high blood pressure, diabetes, and obesity, as well as your lifestyle and nutrition, can harm your kidneys, limiting their ability to function.
We're often told that we should consume a healthy diet. However, for people with kidney disease, also known as renal disease, eating a balanced diet means making sacrifices, such as giving up a favorite dish or drink and many other foods, including healthy ones. Yes, many healthy food items can also exert the kidneys and could lead to additional damage. As a result, people with kidney disease should maintain a healthy kidney diet.

Foods to Avoid with Kidney Disease

Depending on the stage of kidney disease, dietary restrictions differ. People with early-stage chronic kidney disease will have different dietary restrictions than those with kidney failure.
Kidney damage might make it difficult to filter protein metabolic waste products. Unless they are on dialysis, those with chronic renal disease at any stage, especially stages 3–5, should limit their protein intake. Therefore, the doctor will generally recommend minimizing the following food items, while on dialysis:

Processed meats:

Bacon, deli meats, sausage, and jerky are some common types of processed meats. These are preserved by smoking or salting, curing, or adding chemical preservatives and are typically salted with high sodium content.
Excess sodium can cause a strain on the kidneys, hence high sodium diets are not recommended for persons with kidney disease. This can lead to fluid buildup in the ankles, as well as around the heart and lungs.

High potassium fruits:

Fruits are generally healthful and rich in vitamins & minerals. However, people with kidney disease may need to limit their intake of certain fruits mainly those high in sugar and potassium, such as bananas, avocados, apricots, kiwi, and oranges. These fruits are not recommended for people who have kidney disease.

Dried fruits:

Dried fruits are prepared by extracting the water from the fruit using a variety of processes. As a result, small, dense fruits that are rich in energy and nutrients are produced and contain high levels of potassium and sugar, making them problematic for persons who have kidney disease.

Most beans and lentils:

Most beans and lentils are not recommended for people who have kidney disease because they are rich in phosphorus and potassium. If you must eat them, limit yourself to a small portion and choose low-sodium varieties.

Potatoes and sweet potatoes:

Potassium levels in potatoes and sweet potatoes are high, which can be a problem for people with kidney disease, especially for those who are in the late stages.

Packaged Snacks:

Snack foods such as chips, pretzels, and crackers are high in sodium and refined sugar and low in beneficial nutrients. Snack foods should be limited or avoided in any balanced diet, especially if you have kidney disease.

Some leafy green vegetables:

Potassium and oxalic acid are rich in leafy green vegetables like spinach, beet greens, and chard. Kidney stones are more likely to form if you consume too much oxalic acid. In persons who are vulnerable to oxalates, kidney stones can form. Kidney stones can cause more damage to your kidneys and limit their function.
