Does Drinking Tea Cause Kidney Stones Tea Effects On Renal Health
Tea is a big NO for those who suffer from kidney stones. This is because tea has very high oxalate content and oxalic acid aid in the forming of kidney stones. So, does tea cause kidney stones? The answer is yes, drinking too much tea can lead to the formation of kidney stones. However, recent studies prove that green tea may be consumed by those who suffer from kidney stones as it contains a compound that prevents kidney stones from being formed.
Green Tea Health Benefits
Green tea naturally contains several nutrients and antioxidants. Antioxidants help rid the body of free radicals that can affect different aspects of your health, including weight, brain function, cardiovascular health and risk of developing cancer. According to a study published in January 2018 in the Journal of Ethnopharmacology, green tea’s most abundant compound, epigallocatechin gallate , may play a role in improving cardiovascular and metabolic health.

Some older studies indicate that drinking green tea can help with weight loss. By reducing and then maintaining a healthy weight, you lower your risk of developing type II diabetes, which can have a negative impact on your kidney health. However, these studies are based on green tea extract, not the green tea drink. There are also older studies that suggest the results are not significant and that the results vary based on the individual. More research needs to be done to support the use of green tea for weight loss.
Green tea may also benefit people with diabetes by helping regulate blood sugar. According to research published in August 2013 in The American Journal of Clinical Nutrition and several earlier studies, green tea has the potential to help regulate blood sugar. Better blood sugar management helps prevent kidney disease due to diabetes.
Green Tea May Prevent Kidney Stones
Study Shows Compound in Green Tea Extract May Block Formation of Kidney Stones
Kidney stones affect about 5% of the world’s population. They occur when abnormally high concentrations of minerals, such as calcium, accumulate in the urinary tract and clump together to form crystals and potentially painful stones.
Most kidney stones contain calcium, and the most common stone type is calcium oxalate. Chinese researchers found that green tea extract bonds to calcium oxalate and makes the resulting crystals a different shape, which makes them less likely to clump together and form large kidney stones.
The smaller crystals and stones are then passed harmlessly through the urine.
In the study, published in CrystEngComm, Xudong Li of Sichuan University in Chengdu, China, and colleagues examined the effects of green tea concentrate on calcium oxalate crystallization using a variety of advanced scanning and imaging techniques.
The results showed that as the amount of green tea extract applied increased, the calcium oxalate crystals became flatter and flatter.
Researchers say flatter crystals form less stable kidney stones that break up more easily.

Black Tea And Caffeine
Your kidneys are responsible for filtering your blood and producing urine, and they play a role in helping to regulate your blood pressure. Caffeine can interfere with these processes, however, and black tea contains this stimulant. The amount of caffeine in a serving of black tea varies depending on how long the tea was steeped and how much tea was used, but can range between 14 and 47 milligrams, with the average being about 42 milligrams, according to Caffeine Informer. Caffeine can also act as a diuretic, which increases water loss, according to Victor R. Preedy, author of “Tea in Health and Disease Prevention.” Caffeine can increase blood pressure, as well, Preedy notes.
What Do The Kidneys Do
Well-functioning kidneys are vital to excellent health. They eliminate water-soluble wastes and help to balance your electrolytes. They help to maintain the pH of your body. The kidneys help to regulate your hormones and blood pressure and get involved in making your red blood cells. These organs express over 1,548 of your genes. They filter 120 to 150 quarts of blood per day. Then, wastes and toxins get removed through urine to protect you. You simply cannot live without healthy kidneys.
Fun fact: The right kidney is usually lower and slightly smaller than the left because of the livers placement.

What Do You Know About Your Kidney
You have two kidneys and they are bean-shaped organs approx. the size of a fist that is situated below your rib cage on each side of your spine. Each kidney is made up of roughly a million units called nephrons. Each of your nephrons has a filter called the glomerulus and a tubule. The glomerulus filters your blood and the tubule returns what is necessary to your blood. Blood flows to your kidney via the renal artery which is a large blood vessel that splits until your blood reaches the nephrons. Your kidneys filter approx. 150 quarts of blood a day, most of it is returned to your body.
In fact, your kidneys have a higher blood flow than your brain and liver. It is a unique organ given most of us start out with two yet only require one-half of a kidney to filter our bodys blood. In an odd relationship with your liver, kidneys may also produce vitamin D if the liver cannot. Another important component of our kidneys is that they make hormones that directly help control blood pressure, create red blood cells and keep your bones healthy.
Healthy kidneys are important. Due to the functions kidneys perform and the harmful substances that may move through them they are susceptible to a number of issues including kidney failure, kidney stones, uremia, and chronic kidney disease among many others.

Infrequently Asked Questions: Can Drinking Too Much Tea Cause Kidney Stones
The world is full of questions we all want answers to but are either too embarrassed, time-crunched or intimidated to actually ask. In the spirit of that shared experience, weÃ¢ve embarked on a journey to answer all of the questions that burn in the minds of Philadelphians Ã¢ everything from universal curiosities to Philly-specific musings .
Tea drinkers have long feared the answer to the question of whether their hydration method of choice is actually detrimental to their kidney health. Eager to set the record straight, we reached out to Dr. Pooja Singh, a clinical assistant professor in nephrology at Jefferson University Hospital.
Getting to the chase, can drinking too much tea really cause kidney stones?
The answer to that is Ã¢Yes,Ã¢ but only if it is done in an excess amount. And the reason for that is because tea, specifically black tea, which is how we drink tea in America, is very rich in a mineral called oxalates. These are present not only in black tea, but chocolates, spinach, beets and peanuts. So if you have susceptibility for stones you and I, if we are not susceptible to kidney stones, we can perhaps drink a lot more and not have a problem Ã¢Â¦
Is oxalate present in other teas, too?
Specifically if they have a history, not to drink so much black tea. And it also goes with other things like the chocolate and the spinach and other things I mentioned.
How do you know youre susceptible?
