Black beans are a nutritious food, often used in traditional medicine to cool, detoxify, and diuretic.
However, for people with kidney problems, especially people with kidney failure or impaired kidney function, the use of black bean water should be carefully considered.
According to research, people with chronic kidney failure need to strictly control the amount of potassium, phosphorus and protein in their daily diet. Meanwhile, 100g of black beans contain about 148mg of potassium and 140mg of phosphorus. Consuming too much of these minerals can cause accumulation in the blood, leading to electrolyte disorders, increasing the risk of cardiovascular complications and nerve damage in people with kidney failure.
Experts recommend that people with kidney disease should limit the use of natural diuretic solutions such as black bean water, because they can increase the pressure of filtering the renal cau - which is already weakened - and lead to more serious damage if used regularly, without control.
However, for healthy people or those with only mild kidney failure (as permitted by a doctor), black bean water can benefit from its high antioxidant properties from anthocyanins and flavonoids, helping to reduce inflammation and improve blood circulation. According to the World Health Organization, maintaining blood pressure and reducing chronic inflammation are two important factors in preventing kidney damage.
People with kidney failure should not arbitrarily drink black bean water as a folk therapy. The use should be guided by a kidney specialist to avoid the risk of aggravating the condition.
Healthy people can use moderate black bean water as part of a balanced diet.
