Cabbage is a very popular vegetable in the daily diet, known for its many health benefits, especially in providing vitamin C, fiber and antioxidants. But there are diseases that require limiting the use of cabbage in meals.
One of the main reasons why people with kidney disease should limit or avoid eating cabbage is because of the high potassium content of this vegetable. Potassium is an essential mineral for the body, but if kidney function is impaired, the body cannot excrete potassium effectively. This can lead to hyperkalemia, a dangerous condition that can cause heart rhythm disturbances. People with kidney disease need to pay special attention to the amount of potassium in their diet to prevent complications related to hyperkalemia.
Cabbage, especially when eaten raw or uncooked, can contain a significant amount of potassium. A cup of raw cabbage contains about 350-400 mg of potassium, while the daily potassium requirement for kidney failure patients may be only about 1500-2000 mg, depending on the severity of the individual's kidney failure. Eating too much cabbage can easily exceed the recommended potassium intake, putting pressure on the kidneys and increasing the risk of complications.
In addition, cabbage also contains oxalates, a compound that can combine with calcium in the body to form calcium oxalate crystals, causing kidney stones. Although research on oxalates in cabbage is still not completely consistent, some studies have shown that a diet high in oxalates can increase the risk of kidney stones, especially in people with kidney problems. According to experts from the American Society of Nephrology, patients with a history of kidney stones should limit their consumption of foods rich in oxalates to reduce the risk of recurrence.
People with kidney disease should be cautious when consuming cabbage because of both its high potassium content and its ability to form kidney stones. To protect kidney health, patients should consult a doctor or nutritionist to develop a suitable diet.
