Black beans are a rich source, containing: anthocyanins (strong antioxidant pigments), flavonoids and polyphenols, soluble fiber, minerals (magnesium, potassium, iron).
According to the National Institutes of Health, polyphenol compounds in black beans have the ability to neutralize free radicals and reduce inflammation, two factors closely related to liver and kidney damage.
According to the World Health Organization, oxidative stress and chronic inflammation are important causes of fatty liver disease, kidney failure and metabolic disorders.
Anthocyanins in black beans are a group of powerful antioxidants. Many studies published in PubMed show that anthocyanins can:
Reduce liver enzymes;
Protect liver cells from damage caused by free radicals;
Limit fat accumulation in the liver.
This mechanism is especially important in preventing fatty liver disease - an increasingly common disease.
Polyphenols in black beans help improve fat metabolism, reduce triglyceride buildup in the liver. This contributes to reducing metabolic pressure and improving liver function in the long term.
Black beans have high potassium and water content when cooked into tea, which helps increase urine volume and supports the kidneys in eliminating waste.
According to the National Kidney Foundation, maintaining adequate water and electrolytes helps improve filtration function and reduce the risk of kidney stones.
The flavonoids in black beans have anti-inflammatory effects, helping to reduce micro-injury in glomerular kidneys, and limit the progression of chronic kidney disease.
Many nutrition studies have also noted that a diet rich in polyphenols can help reduce oxidative stress in the kidneys.
An important factor affecting the kidneys is blood sugar. Black beans have a low glycemic index and high fiber content.
This helps stabilize blood glucose - an important factor in preventing kidney complications from diabetes.
Black bean tea is usually prepared by gently roasting black beans, boiling water to drink instead of tea.
This method helps retain most polyphenols and anthocyanins, while increasing the easy-to-drink flavor in the summer.
You can use 1-2 cups/day; drink warm or cool.
Despite many benefits, it should be noted not to replace drugs to treat liver and kidney diseases; do not abuse them (which can cause bloating due to a lot of fiber).
People with severe kidney failure need to consult a doctor (due to potassium content).
To protect the liver and kidneys sustainably, it is necessary to combine a healthy diet, drink enough water and maintain a scientific lifestyle.
