However, not all vegetables are kidney-friendly. People with kidney problems need to pay attention to the potassium, oxalate, or phosphate content. For example, with potassium, the kidneys are the main organ responsible for eliminating it from the body. When kidney function is impaired, the ability to remove potassium is also reduced, leading to potassium accumulation in the blood and endangering the heart, according to the health website Healthline (USA).

Below are vegetables that are considered beneficial for kidney function and support the body's detoxification process.
Red bell peppers
Red bell peppers are one of the recommended vegetables in a kidney-friendly diet. This is because they are low in potassium but rich in vitamin C, vitamin A, folate and fiber.
Bell peppers contain antioxidants such as lycopene and carotenoids, which help reduce oxidative stress and inflammation. These are two factors that contribute to kidney cell damage when the body has chronic diseases such as kidney failure and diabetes.
In addition, although red bell peppers are low in potassium, people with severe kidney failure still need to control the total amount of potassium-rich vegetables per day as recommended by their doctor.
Cabbage
Cabbage is rich in phytochemicals, vitamin C, vitamin K and fiber but has a relatively low potassium content. Compounds such as glucosinolate in cabbage stimulate the production of detoxifying enzymes in the liver, helping to break down toxins, thereby reducing pressure on the kidneys.
Cabbage contains polyphenols and sulforaphane, which have antioxidant and anti-inflammatory properties, thereby protecting the renal blood vessels and renal interstitial tissue from damage. The best ways to eat cabbage are raw, boiled, stewed, or stir-fried with lean meats.
Celery is good for the kidneys
Celery is beneficial for the kidneys because of its mild diuretic properties, its ability to reduce uric acid and help eliminate toxins through urine. Specifically, some active ingredients in celery such as apigenin and luteolin help reduce uric acid levels in the blood and stimulate urine excretion, thereby helping to flush out waste products in the urinary tract.
People can take advantage of the nutrients in celery by juicing, boiling, stir-frying or cooking soup with other tubers.
Spinach
Spinach is a dark green vegetable rich in vitamins A, C, K, folate and antioxidants such as lutein. In addition, the carotenoids and flavonoids in spinach help fight inflammation and protect kidney cells from damage.
One thing that not everyone knows is that green vegetables like spinach help reduce the amount of acid that the kidneys have to process after food is metabolized. As a result, the pressure on the kidneys will be reduced.
However, spinach is high in oxalates, which can lead to kidney stones if consumed in excess. It is best to cook it thoroughly or blanch it to reduce the amount of oxalates, according to Healthline .
