Your Physician Prescribes How Much
I will be offering as much variety as I can, and encouraging you to drink, but the volume you need comes from your physician. This applies especially to my two day long examples. I made them to provide very large amounts of fluids for those who need them. If your physician prescribes less, just scale my recommendations back. Under no circumstances should you follow a fluid prescription in this post unless it fits with your physicians specific recommendations for you.
The Solution: Which Teas Are Best For Kidneys
Not all teas are cause for concern when it comes to kidneys. There are plenty of tea types that havent been linked to kidney disease, and in fact may help improve kidney health! The key you may have learned by now is levels of caffeine and oxalates, and also other constituents like certain antioxidants which can actually be beneficial to kidney health.
Dont Underestimate Your Sweat
Saunas, hot yoga and heavy exercise may be good for your health, but they also may lead to kidney stones. Why? Loss of water through sweating whether due to these activities or just the heat of summerleads to less urine production. The more you sweat, the less you urinate, which allows for stone-causing minerals to settle and bond in the kidneys and urinary tract.
One of the best measures you can take to avoid kidney stones is to drink plenty of water, leading you to urinate a lot. So, be sure to keep well hydrated, especially when engaging in exercise or activities that cause a lot of sweating.

What Is The Relationship Between Green Tea And Kidney Stones
Green tea has actually been shown to reduce the risk of kidney stone formation in women by a respectable eight percent. In men, that risk reduction increases to 14 percent. While green tea still leads to an increase of oxalate in the blood, it adversely impacts crystal formation, which is the kidney stone.
How Does Green Tea Help Prevent Kidney Stones?
It is believed that the extract from green tea ends up adhering itself to the calcium oxalate as it is emitted. This impacts the way that the crystals are formed in comparison to other types of tea. In essence, the crystals formed from green tea do not clump together like they normally would.

Im an avid tea drinker. I love tea, especially green tea, and all of the benefits it can offer. For example, green tea improves health and promotes weight loss. And mint tea can help with stomach aches. One thing Im wondering is if tea can cause kidney stones. My friend posed this question to me a few weeks ago, and ever since then, that question has been swirling around my head especially if Im drinking a cup of tea.
According to EverydayHealth.com, an article they published stated that drinking iced tea may cause kidney stones. The article notes that because tea consists of oxalates, kidney stones have an increased chance of forming in the kidneys. An oxalate is a common chemical that causes kidney stones to form. The article also points out that iced tea has a greater chance of creating kidney stones than hot tea. And while tea may contain oxalate, does correlation equal causation?
For example, while oxalates may be correlated with creating kidney stones, this does not necessarily mean it is the cause. Many other factors can attribute to causing kidney stones. These factors, confounding variables, could be the solution to this question of whether tea causes kidney stones or not. Some possible third variables may include genetics, gender, exercise, diet and age. And of course, chance could always be the answer to the hypothesis.

Why Drinking Too Much Iced Tea Caused This Mans Kidneys To Fail
Iced tea is delicious no one here is denying that. But like with most great things, too much of it can bring about dire consequences.
Such is the story of an Arkansas man who drank so much iced tea that it led him to develop kidney failure. Three Arkansas doctors described the case in a letter published by the New England Journal of Medicine this week.
The 56-year-old man showed up at the hospital in May 2014 with weakness, fatigue and body aches, along with high levels of creatinine, which is used as an indicator for kidney function.
Doctors asked: Do you have a history of kidney stones in your family? No.
What about kidney disease? No.
The questions continued, the doctors write, until eventually “the patient admitted to drinking sixteen 8-oz glasses of iced tea daily.”
Yeah, that’s a lot of iced tea. A gallon of it, actually.
Black tea is rich in the food compound oxalate, which had likely clogged the man’s kidneys and inflamed them, leading to renal failure and the need for dialysis.
“In this case there were oxalate crystals inside the kidney, and that generates an inflammatory reaction,” Umbar Ghaffar of the University of Arkansas for Medical Sciences told Reuters. “If that’s not resolved it will cause scarring and loss of the kidney tissue. So that’s what probably was happening in this patient.”
But at 16 cups of black iced tea a day, the Arkansas patient took in more than 1,500 milligrams of oxalate every day.
So, bottoms up — to a limit.

Is Tea High In Oxalate
While tea is relatively high in oxalate compared to many foods, its important to remember that the serving size of tea is usually dozens or hundreds of times less than other foods.
According to several studies, heres how much soluble oxalate various types of tea leaves and tea liquid yield:
- Black tea leaves: 4.61-5.11 milligrams of oxalate per gram of leaf
- Black tea liquid: 4.41-4.92 milligrams of oxalate per cup
- Chinese green tea liquid: 1.9 to 27.96 milligrams of oxalate
- Chinese oolong tea liquid : 6.89 milligrams of oxalate per cup
- Green tea powder or matcha: 12.6 milligrams of oxalate per 2-gram serving
Now, for comparison, here is the oxalate content of some common foods.
High oxalate foods that may increase the risk of kidney stones:
- Purslane: 1294 mg oxalate per 100 grams fresh weight
- Spinach: 970 mg oxalate per 100 grams fresh weight
- Cocoa: 700 mg oxalate per 100 grams
- Sorrel 500 mg oxalate per 100 grams fresh weight
- Rhubarb: 260 mg oxalate per 100 grams fresh weight
- Cashew: 231 mg oxalate per 100 grams
Medium- and low-risk foods with less oxalate:
- Parsley: 170 mg oxalate per 100 grams fresh weight
- Potato: 80 mg oxalate per 100 grams fresh weight
- Cabbage: 60 mg oxalate per 100 grams fresh weight
- Tomato: 20 mg oxalate per 100 grams fresh weight
- Apple: 15 mg oxalate per 100 grams fresh weight
- Lettuce: 12 mg oxalate per 100 grams fresh weight
Is There A Link Between Iced Tea And Kidney Stones
Kidney stones are a very painful medical problem. In fact, some women describe the pain as being worse than childbirth. Kidney stones form as a result of hardened mineral deposits and urologists say that people who consume high amounts of oxalates could be at an increased risk. Along with spinach and chocolate, iced tea happens to have plenty of oxalates.
You can hear more about the link between iced tea and kidney stones by watching this brief video and consulting your urologist. The health expert interviewed here recommends drinking plenty of water with a lemon wedge to counteract the effects of the oxalates in iced tea.

Is hot tea bad for kidney stones?
Summer is high season for drinking iced tea. However, a John Miller, Loyla University Medical Center urologist warns that iced tea can contribute to painful kidney stones because of its high concentration of oxalate, one of the key chemicals that lead to the formation of kidney stones.
Too Much Iced Tea Can Lead To Kidney Stones: Urologist
When the summer heat hits, consider reaching for freshly squeezed lemonade or water rather than iced tea, which experts say can lead to the formation of painful kidney stones.
It’s the quintessential summer drink and the thirstquencher of choice at backyard barbecues and outdoor patios. But a urologist at Loyola University Medical Center in Chicago warns consumers that iced tea contains high concentrations of oxalate, one of the key chemicals that can lead to kidney stones.
Though in healthy bodies kidney stones — small crystals made up of minerals and salts found in the urine of kidneys or ureters — are expelled naturally from the body, stones can grow large enough to become lodged in the small tubes that drain urine from the kidney to the bladder.

What About Black Tea And Kidneys
In my kidney stone definition earlier, I mentioned that stones are caused by substances that crystallize in the kidneys. One of those crystal-forming substances is oxalate.
Well, black tea has a higher oxalate content than many other beverages. Drinking it leads to more oxalates in the urine, and it can promote stone formation if you consume too much .
One particularly memorable case of this occurred in 2014, when a man developed renal failure because he was drinking a gallon of black tea daily, which led to a heavy load of oxalates . Turns out there can be too much of a good thing!
Green Tea And Kidney Stones Studies And Findings
A study has recently claimed that for each cup of green tea consumed daily, women reduced the risk of having kidney stone by 8 percent. For men the risk would go down by as low as 14 percent. These findings however initially confused scientists, because they discovered that the level of calcium oxalate in urine had increased due to the consumption of green tea which basically meant a higher risk of kidney stone.
Later in their studies they were able to figure out that it was not just about the oxalate level but also about how it affects the crystal formation.

Drinking Too Much Iced Tea Causes Mans Kidney Failure
Doctors traced an Arkansas mans kidney failure to an unusual cause his habit of drinking a gallon of iced tea each day.
They ruled out several potential causes before stumbling on a reason for the 56-year-old mans kidney problems. He said he drank about 16 8-ounce cups of iced tea every day. Black tea has a chemical known to cause kidney stones or even kidney failure in excessive amounts.
It was the only reasonable explanation, said Dr. Umbar Ghaffar of the University of Arkansas for Medical Sciences in Little Rock. She and two other doctors describe the case in Thursdays New England Journal of Medicine.
The unidentified man went to the hospital last May with nausea, weakness, fatigue and body aches. Doctors determined his kidneys were badly clogged and inflamed by the food chemical called oxalate. The man is on dialysis, perhaps for the rest of his life, Ghaffar said.
Besides black tea, oxalate is found in spinach, rhubarb, nuts, wheat bran and chocolate. In rare cases, too much oxalate can lead to kidney trouble, but often theres also a contributing intestinal problem. That didnt seem to be the case for the Arkansas man, and he had no family or personal history of kidney disease.
At 16 cups of iced black tea each day, he was taking in three to 10 times more oxalate than the average American, Ghaffar and her colleagues reported.

The Relationship Between Oxalate And Kidney Stones
Unless youre already aware of oxalate, you may be surprised to learn that many leafy greens and plant foods contain high levels of an antinutrient thats linked to higher risk of kidney stones.
Oxalic acid or oxalate is a naturally-occurring compound in plants that interferes with the absorption of calcium.
The main concern with diets high in oxalate is the formation of kidney stones.
For example, research has shown that some vegetarians and vegans who eat lots of plant foods consume more oxalate, and thus may be more likely to get kidney stones.
Kidney stones are small, hard deposits of minerals that form in your kidney and pass through your urinary tract. The most common symptoms are waves of severe pain and nausea, usually in the side of the abdomen.
Some people seem to be more sensitive to dietary oxalate than others. As a result, doctors sometimes recommend a low oxalate diet to prevent the recurrence of kidney stones.
Peoples Pharmacy Bottom Line:
Do not become dehydrated Keep iced tea consumption moderate, especially in the summer Avoid grapefruit juice Drink lemonade if you are at risk of developing a kidney stone When in doubt drink water! Keep calcium intake from supplements under 800 mg per day Increase calcium intake from vegetables and other foods Consider more magnesium from green leafy veggies or from a supplement Consider probiotics periodically
If Symptoms develop seek immediate medical attention!

Ask Kidneystonersorg: Is Instant Tea As Bad As Real Tea
i was just in the hospital for the 2nd time with kidney stones. My question is, is instant tea as bad for you as real tea? Also what are some main foods and drinks i should avoid to prevent getting them again?
Answer:
Instant tea has a similar amount of oxalate as regular tea. Below, in order of decreasing amount of oxalate, is a list of different foods and types of teas containing oxalate.
| Food item | |
| 1236 mg per 200 gm | One box spinach |
| 126 mg per 90 gm | About one bar |
| 0.68 mg per gm | 1.36 mg per cup |
For most stone formers however, the three most important things to remember are to increase the amount of water you drink, decrease the amount of salt you ingest, and decrease the amount of meat protein you eat. Guidelines for salt and meat intake are similar to what is advised for all adults .
In addition to this, keep a normal calcium intake and a moderate oxalate intake. You may also want to undergo testing with your doctor to see if a high oxalate level in the urine is truly an issue for you. Unless you have hyperoxaluria, restriction of oxalate containing foods may not be of much benefit.
In our Ask KidneyStoners.org section, we field questions from stone formers or their family members. See previous questions and answers here.
