Is Tea High In Oxalates

Expert busts myth that fresh milk tea causes kidney stones

The main source of dietary oxalates are plants and plant products, especially leafy plants and seeds related to rhubarb and spinach. Oxalates also occur in the leafy plant Camillia sinensis better known as the tea plant from which tea leaves are harvested.

Rule of Thumb:

Non-fermented or lightly fermented teas such as white and green tea have less oxalates than darker, fermented teas such as Black tea, Puerh and Kombucha .

Oxalate comparison in various tea types

  • Darker Tea : approx. 224 mg/200mL
  • Black Tea: approx. 156 mg/200mL
  • Green Tea: approx. 80 mg/200mL
  • Herbal Tea: Very low to non-detectable

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.

Which Type Of Tea Causes Kidney Stones

Now, after knowing that green tea prevents the formation of kidney stones, you might be thinking that the effect is the same with other tea varieties as well. Arent you?

However, this is not true!

There are teas that cause kidney stones. Those who already suffer from kidney stones are not supposed to drink tea. This is because tea contains a high amount of oxalate that leads to the formation of kidney stones.

If you consume too much tea you can end up with kidney stones.

Now, as already discussed, green tea has a preventive effect with regard to kidney stones and this shows that not every tea causes them. It all depends on the oxalate level of tea.

When compared to green tea, black tea has a higher amount of oxalate present in it and therefore should be avoided.

P.S. It is still not very clear whether by bringing down your consumption of oxalate-rich foods you can prevent kidney stones or not. So, those with a history of kidney stones need to limit their consumption of food and drink that has more amount of oxalate.

You can always drink green tea as the amount of oxalate in it is quite less when compared to that of black tea.

Iced Tea Consumption Linked To Kidney Stones

Related tags:, Tea, Coffee

Summer is the top time for consumption of iced tea beverages, but Dr John Milner, of Loyola University Medical Center, USA, warned: “For people who have a tendency to form the most common type of kidney stones, iced tea is one of the worst things to drink.”

Milner explained that iced tea contains high concentrations of oxalate, which is one of the key chemicals that lead to the formation of kidney stones. He noted that the most common cause of kidney stones is dehydration from not drinking enough fluids.

During the warmer summer months people can become dehydrated from sweating, he said, adding that this, combined with increased iced tea consumption, raises the risk of kidney stones, especially in people already at risk.

“People are told that in the summertime they should drink more fluids,” he said. “A lot of people choose to drink more iced tea, because it is low in calories and tastes better than water. However, in terms of kidney stones, they might be doing themselves a disservice.”

Oxalate risk?

Oxalates are naturally-occurring organic acids found in plants, and animals. Oxalate is also formed during the normal metabolism processes, and is excreted by the kidneys through urine.

However, because oxalate and calcium are continuously expelled through the urine, they can combine to form calcium-oxalate crystals if the concentration of oxalate is too high to be diluted.

Not Sweet: Too Much Iced Tea Causes Kidney Failure

Does Consuming Tea Cause Kidney Stones?

Office of Public Affairs

Drinking tea is good for your health. It may lower the risk of cancer, it can encourage weight loss, and recent studies have shown tea can help lower blood pressure.

But one Arkansas man discovered there can be too much of a good thing.

In May 2014, a 56-year-old man arrived at Central Arkansas Veterans Healthcare System, complaining of weakness, fatigue and body aches. Doctors discovered that his kidneys were failing. He was placed on dialysis. After questioning the patient, they learned that he drank 16 8-ounce glasses of iced tea daily, which is about 1 gallon.

Iced tea is full of oxalic acid, which, when taken in excess, deposits in your kidneys and mucks up the work of removing waste from the blood, says Scott Youngquist, MD, an emergency physician at University of Utah Health. This patient was drinking 16 8-ounce glasses of iced tea per day for an unknown period of time. This created a load of oxalic acid that his kidneys couldn’t handle, leading to renal failure.

Black tea is rich in oxalate, a compound found naturally in many foods. Too much of it can also lead to kidney stones. The man likely consumed 1,500 milligrams of the compound daily. As a comparison, the average person ingests between 150 and 500 milligrams of oxalate each day.

This kind of kidney failure has also been reported due to excessive consumption of star fruit, cucumber fruit, rhubarb and peanuts, Youngquist says.

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.

Unless youre Joey from Friends, and its an unbearable experience all around.

Research On Green Tea

Although more research is needed, much research shows that green tea can help ward off kidney stones before they occur. According to a November 13, 2009 article in PhysOrg.com, green tea contains compounds called “phenols” that make it more difficult for large kidney stones to form by changing the shape of the mineral crystals so they cannot clump together 2. A study in the May 2006 “Journal of Endourology” reported that epigallocatechin gallate, one of the main polyphenols in green tea, inhibited urinary stone formation in rats through its antioxidant effects 34. In the January 2005 edition of Journal of Urology, researchers reported that green tea decreased calcium oxalate stone formation in rats, alleging that this correlation was likely due to the antioxidants in the tea 3.

Four Myths About Kidney Stones

If you’ve ever had a run-in with kidney stones, then you’ve also had a run-in with a relative/neighbor/obnoxious over-sharer who has the home remedy that fixed them right up.

And while unsolicited after-dinner medical advice may sometimes sound reasonable, there’s a lot you need to know about your own kidney stones before you start adjusting your diet based on Aunt Alice’s latest stone story.

“You don’t want calcium because that’s what stones are made of, so ditch the milk.””Oxalates are bad, so stop eating foods like chocolate, beer, soy, nuts, spinach and coffee.””And if you feel a stone coming on, start drinking lots of cranberry juice to get rid of it.”

You’ve probably gathered lots of advice and home remedies in your battle against kidney stones . But many of grandma’s homemade fixes may actually do more harm than good when it comes to the specific composition of your kidney stones and the reasons why you are forming them.

What are kidney stones? They’re crystal-like formations of the excess minerals in your urine. This simple answer leads to simplified and problematic responses. The logic: Identify what you’re consuming, and reduce whatever the stone is made of.

Mayo Clinic Q And A: Reducing Your Risk Of Kidney Stones

Does Arizona Green Tea Cause Kidney Stones

Dear Mayo Clinic: My father has a history of kidney stones. He has changed his diet in the past year, which seemed to help. I’m concerned though, since I had heard kidney stones can increase during the summer. Is this true? If so, are there any tips for how he can further reduce his risk?

Answer: As temperatures rise during the summer months, so does the risk of developing kidney stones, even if you have never had one before. There are several reasons why there is a rise in kidney stones during the summer months. Among these reasons are an increase in outdoor activities, and the amount and types of food and drink we consume.

Research shows that as the weather warms up, people spend more time outdoors, doing yardwork, spending time at the pool or around a barbeque. And often the body is not getting the type of fluids it needs while losing more than normal via the skin.

Kidney stones are hard deposits of minerals and salts that form inside your kidneys. They develop when your urine contains more crystal-forming substances, such as calcium, oxalate and uric acid, than the fluid in your urine can dilute.

There are several causes for kidney stones, including diet, which can play a significant role in the formation of kidney stones. A family or personal history of kidney stones raises your risk, as do certain medications and medical conditions.

Is Tea Good For Kidney Disease

There is nothing like a good soothing cup of tea, especially in the cold weather months! But, if you have kidney disease, you might be wondering if certain types of teas can help or harm your kidneys.

We hear this question often, so were diving into the different types of teas and any considerations to keep in mind for kidney health!

But first, a little background.

What Causes Kidney Stones

Dr. Hammontree discussing ice tea effects of Kidney stones

Now, we are finally at the part you have likely been waiting for all this while. Unfortunately, there is no single cause of kidney stones. Instead, they result from a combination of factors. The more of these factors in play, the more you are likely to suffer this condition.

You see, the stones come about when your urine has a high concentration of crystallizing substances. These include calcium, uric acid, and oxalates. Woe unto you if you have plenty of these. With tea, you will find that most of the concerns surround the oxalates presence, as we will later cover.

When you have too many of these substances than your urine can dilute, they start sticking together. And slowly, kidney stones develop.

Which Tea Is Good For Kidney Disease

In order to cleanse your kidneys and keep them working fine, all you need to do is to drink a lot of water. Staying well-hydrated is usually enough to help them function right.

While drinking green tea is beneficial for the health of your kidneys, those with existing kidney disease should avoid it.

Annique Health and Beauty mention that Most teas, like green or black, contain a compound called oxalic acid. Its also found in chocolate, certain fruits, vegetables, and raw leafy greens.

Normally, oxalic acid is naturally eliminated through your urine. But when you dont drink enough water, consume too much sugar, and have a diet high in oxalic acid, oxalate crystals can form.

This is one of the most common causes of kidney stones.

But Rooibos Tea doesnt contain oxalates. Thats why its a great alternative to green or black tea for those who are prone to kidney stones.

However, as said earlier, it is always better to consult with the kidney specialist and follow his or her advice.

Does Sweet Tea Cause Kidney Stones

Although drinking more fluids is an effective method of reducing kidney stones, all beverages are not created equal.

A 2013 study looking at sugar sweetened found that drinking the sugar sweetened soda was associated with a higher risk of developing calcium-oxalate kidney stones. Fructose has been shown to increase the output of oxalate in the urine.

Many ready-to-drink sweet iced teas also use fructose to sweeten, thus nutritional labels of commercially available iced teas should be considered .

Green Tea And Kidney Stones A Benefit Or Burden

If you suffer from or are prone to developing kidney stones, you may have a dilemma whether to drink tea.

Kidney stones aremineral deposits made up of calcium, uric acid or the amino acidcysteine. At least three quarters of kidney stones are composed ofcalcium combined with phosphate or oxalicacid.

Tea is aconcern because it is rich in oxalic acid and you could drink tea with milk, which contains calcium.

However, a 2002 study conducted in New Zealand found that unlike black tea, green tea contains only a tiny amount of oxalate. In addition, you are much less likely to drink green tea with milk, meaning calcium is less likely to bind to the tea!

To quote from the study:

The mean soluble oxalate contents of black tea in tea bags and loose tea leaves were 4.68 and 5.11 mg/g tea, respectively, while green teas and oolong tea had lower oxalate contents, ranging from 0.23 to 1.15 mg/g tea.

Existing scientific evidence also suggests that not only green tea is unlikely to cause kidney stone, it could even reduce the risk of getting kidney stone.

A 1998 American study published in the April edition of the Annals of Internal Medicine found that drinking tea reduces kidney stones risk in women.

Researchersexamined 81,093 woman nurses who were 40 to 86 years of agein 1986 with no history of kidney stones. They found that the risk ofstone formation reduced by 8% for each 240 millimeters cup of teaconsumed eachday.
