Introduction
Generally speaking, cabbage is high in potassium and can be consumed in moderation by people with kidney disease. Cabbage indeed contains a relatively high amount of potassium. Specifically, every 100 grams of Chinese white cabbage contains approximately 199 to 200 milligrams of potassium, while every 100 grams of bok choy can contain as much as 274 milligrams. This makes cabbage a good dietary source for potassium supplementation.

Generally speaking, Chinese cabbage is high in potassium and can be consumed in moderation by individuals with kidney disease. Chinese cabbage contains a relatively high amount of potassium; specifically, every 100 grams of napa cabbage contains approximately 199 to 200 milligrams of potassium, while the potassium content in bok choy can reach up to 274 milligrams per 100 grams. This makes Chinese cabbage a good dietary source for potassium supplementation.

From a general perspective, patients with kidney disease can consume Chinese cabbage in moderation. Besides being rich in potassium, Chinese cabbage also provides various other nutrients beneficial to kidney disease patients, such as low sodium content, abundant vitamin C and dietary fiber, and low calories. Although high potassium intake may be detrimental under certain conditions—such as when kidney function is severely impaired—under proper management, potassium-rich foods like Chinese cabbage may help lower blood pressure, alleviate symptoms of hypertension, and support the recovery of kidney function. However, special caution is needed and medical guidance is recommended, especially for patients who already have impaired kidney function. As a low-calorie vegetable, Chinese cabbage can provide essential nutrition without placing excessive burden on the digestive system.

In cases of severe illness or after surgery, patients should strictly remain in bed to minimize physical activity. This helps the body repair damaged tissues and promotes the recovery of kidney function.
