Best Foods for Kidney Health, Know how to Keep Them in Check

What is a Kidney?

The kidneys are two bean-shaped organs the size of your fist, located on the left and right sides of your spine. They are among the most vital organs in the body.

What are the functions of the Kidneys?
Kidneys are part of the body’s renal system. Some of the core functions of these organs include:

  • Waste Excretion

The kidneys filter out toxins, excess salts, and urea, a waste from cell metabolism. The excess urea in the body is expelled from the body in the form of urine.

  • Removal of Excess Fluid

Kidneys regulate the body’s water level by removing the excess fluid as urine and retaining the necessary amount in the body. When these organs fail, they are unable to balance fluid levels in the body. The excess body fluid leads to swelling.

  • Blood Pressure Regulation

Kidneys are essential for blood pressure regulation. When it falls too low, the kidneys produce a vessel-constricting protein that signals the body to retain water and sodium. This helps keep the body’s blood pressure in check.

  • Balance of Essential Minerals

The kidneys are responsible for regulating vital minerals like potassium, sodium, phosphorus, and calcium in the body. Changes in sodium levels may affect a person’s mental state, whereas imbalances of potassium in the body may adversely affect the rhythm of an individual’s heart. The calcium and phosphorus levels in the body also need to be maintained in order to promote the growth of healthy bones.

  • Production of Red Blood Cells

One of the hormones produced by the kidneys is erythropoietin which plays an essential role in the production of red blood cells. When kidney failure occurs, the production of this important hormone is inhibited which results in low red blood cell count. This often leads to anemia.

  • Acid Regulation

The process of body metabolism normally results in the production of acids. The kidneys are responsible for balancing the acidity level in the body by removing excess acids.

However, due to the intensive work the kidneys do, they often come into contact with hazardous toxins.

These toxins make the kidneys very prone to various problems which may lead to acute kidney failure. When this happens, the kidneys suddenly lose the ability to function properly. This can be brought about by a number of things including:

– Urinary tract infections
– Blood-clotting disorders
– Autoimmune kidney disorders
– Kidney infection
– Low blood pressure

Foods That Help to Improve Kidney Health

Having healthy kidneys is very vital if body health is to be maintained. Fortunately, there are plenty of foods that help to promote kidney health. These include:


Garlic is an ingredient that is added to food to improve flavor. Apart from its use as a spice, garlic also has numerous health benefits. Studies have shown that garlic offers impressive renoprotective effects in patients with type 2 diabetes.

If you are undergoing a kidney diet, use garlic in your stews and salads to make them more nutritious and tasty.

Cauliflower is one of the best foods for kidney health. This superfood is rich in folate, fiber, and Vitamin C which are necessary for kidney function. Aside from these essential compounds, cauliflower also contains several chemicals that neutralize toxins in the body.

You can substitute cauliflower for potatoes in your kidney diet due to their low potassium content.

Red Bell Peppers

However, they are also very beneficial for a kidney-friendly diet for various reasons. First, red bell peppers are an excellent source of Vitamin A, Vitamin B6, and Vitamin C. These foods also contain lycopene, an important antioxidant that helps prevent certain types of cancer.


Cabbages are cruciferous vegetables that are rich in Vitamin B6, Vitamin K, and folic acid. These kidney-friendly vegetables are also packed with phytochemicals that help protect against and fight cancer.

Due to their low potassium content and affordability, cabbages can be a great addition to a kidney diet. You can steam them or grate them and use them as toppings for fish stew.


Many people primarily use onions to add flavor to their meals. However, these sulfur-containing foods are also essential to a kidney-friendly diet thanks to the numerous flavonoids it contains.

One of the most important flavonoids contained in onions is quercetin which prevents heart disease and protects against some types of cancer.

Another highly important mineral contained in onions is chromium which helps in the metabolism of protein, carbohydrate, and fat.

There are different onion varieties that you can add to a kidney-friendly diet. You can eat them raw in vegetable salads or fry them into onion rings if you prefer them crunchier.

Fish Is One of The Most Nutritious Foods Due To Its High Protein Content.

Egg yolks are nutritious foods that are very protein-rich. However, their high phosphorus content makes them unsuited for people who are maintaining a kidney-friendly diet. Since egg whites have much lower phosphorus content, they are particularly great for people undergoing a renal diet.

In addition to this, egg whites are recommended for people who are undergoing dialysis treatment since they need a protein-rich diet with less phosphorus. You can prepare a nutritious kidney diet with eggs in several ways. Make an omelet sandwich or add the whites of boiled eggs to tuna stew meals to increase protein content.


This superfood also contains anti-inflammatory fats known as omega-3s. These fats are very crucial in fighting diseases such as cancer and heart disease. Omega-3s also help lower LDL cholesterol which is bad cholesterol and raise HDL cholesterol which is beneficial for the body.

Research has also shown that the consumption of these polyunsaturated fatty acids (PUFA) can slow down the progression of kidney disease. This makes fish one of the best foods for a kidney diet.

Pumpkin Seeds

Pumpkin seeds are packed with fiber, vitamin E, Zinc, Copper, and protein which are very vital in the body. Research has shown that pumpkin seeds can significantly lower the risk of kidney stones. Nevertheless, these foods also have high phosphorus content. If you are thinking of adding them to your kidney diet ensure you consult with your doctor beforehand.


These tasty fruits contain antioxidants anthocyanins and ellagitannins which help protect the structures of body cells. Berries are also rich in Vitamin C and fiber making them highly beneficial if you are undergoing a renal diet.
Strawberries lend themselves well to a lot of uses and recipes. You can add them to cereals to make them tastier and more nutritious. Alternatively, you can also use them as toppings in fruit smoothies or ice creams.

Red Grapes

Red grapes are rich in flavonoids which give them their distinct reddish color. These flavonoids are essential to the body because they protect against heart disease as well as prevent the formation of blood clots.

The flavonoid Resveratrol which is found in red grapes also aids in the production of nitric oxide which relaxes blood vessels. This facilitates the better circulation of blood in the body.

If you are maintaining a kidney diet, there are several creative uses for red grapes.
