Is drinking tea beneficial or harmful to our health? This topic has been discussed for a long time. Some research suggests that tea can have a variety of health benefits if consumed in moderation. Especially researchers have found black tea more beneficial for health. Black tea is rich in antioxidants and can improve problems ranging from heart to gut and diabetes.

Black-tea was very much discussed during the Corona epidemic. The researchers found that its use can strengthen the body's immunity, which is beneficial for keeping you safe from infectious diseases.

But in some recent reports, health experts have warned that black tea should not be consumed in excess, as it may increase the risk of kidney diseases. Its consumption is safe only as long as you drink it in small quantities.

The caffeine content in black tea
Consumption of black tea is beneficial in everything from diabetes to heart disease, so many studies have been done to understand how it is harmful to the kidneys. Mixed results were seen in the studies. Researchers found that caffeine is the primary ingredient in tea and coffee that can have both positive and negative effects on the kidneys.

Studies have shown that caffeine, however, is beneficial for the kidneys because it has a diuretic effect and can improve the glomerular filtration rate (GFR). Through GFR, it is tried to understand how well your kidney is working.

Side effects of caffeine
While caffeine is known to have beneficial effects on the kidneys, it also has some side effects. Caffeine can affect your blood pressure. Some studies have found that excessive consumption of caffeine can increase both systolic and diastolic blood pressure. Since high blood pressure is a major risk factor for kidney disease, foods high in caffeine may increase the risk of kidney problems.

Its disadvantages due to oxalate
Black tea is considered to be the most harmful to the kidney due to the amount of oxalate found in it. It contains a high concentration of soluble oxalate. These oxalates bind to calcium and can form crystals, which can lead to kidney stones. This is the reason why excessive consumption of black tea is believed to increase the risk of kidney stones.

What is the advice of experts?
Health experts say that black tea is beneficial for health in many ways in studies. It has benefits in reducing heart disease, especially cholesterol, and controlling blood sugar, but consuming it in moderation is considered beneficial. Excess of black tea can be problematic for the kidney. It should not be consumed in more than two cups in a day.
