Is Coffee Bad For Your Kidneys
Lets turn our attention to your morning cup of joe. This ones a little more complicated than a yes or no answer when it comes to its effect on kidney health.
First of all, drinking multiple cups of coffee increases levels of potassium in your bloodstream – which your kidneys have to work to filter out. In addition, the creamer you might put in your coffee contains phosphates, which should be avoided by those with kidney disease .
Furthermore, drinking lots of coffee does not hydrate you, so make sure you are drinking enough water along with it to decrease the risk of stones .
Interestingly, coffee may not be all bad for the kidneys! One study showed that consuming one to two cups of coffee may protect against end stage renal failure. The benefit could be due to a phytoestrogen in coffee called trigonelline .
However, more studies are needed, as it is the only study of its kind so far that I found. In a genome-wide association study on coffee and kidney health, the authors also found support for the above conclusions. For now, the evidence so far seems to indicate that coffee has a protective effect .
The University of Chicago notes that coffee contains low levels of oxalates which is part of the reason they also agree that overall it has a protective effect. But bear in mind the caffeine side described earlier .
Not Drinking Enough Water
Staying well hydrated helps your kidneys clear sodium and toxins from the body. Drinking plenty of water is also one of the best ways to avoid painful kidney stones. Those with kidney problems or kidney failure may need to restrict their fluid intake, but for most people, drinking 1.5 to 2 liters of water per day is a healthy target.
Chamomile Tea And Kidneys
Like rooibos, chamomile tea is caffeine free and low in tannins and oxalates .
However, chamomile may have more than just a neutral effect on kidneys. In an animal study, animals with nephrotoxicity were administered chamomile and it was found to improve kidney function .
Chamomile also reduces kidney dysfunction as a result of high fat diets. Long story short, theres pretty good evidence that chamomile is good for kidneys ! That is a cup of good news.

Is Turmeric Tea Good For Kidney Disease
Turmeric tea can be helpful for kidney disease patients as it might help the kidneys in expelling out the toxic wastes from the body.
Turmeric tea may also be helpful for people suffering from polycystic kidney disease as the studies show that curcumin inhibits the growth of cyst formation in patients with PKD .
Polycystic kidney disease is an inherited disorder that can lead to the development of numerous cysts in the kidneys. The cysts are fluid-filled sacs that can cause swelling in the abdomen.
Evidence suggests that curcumin was able to demonstrate significant inhibition of the development of these fluid-filled cysts, which means it slowed down the cyst formation.
Again, a lot more further research is needed on this topic but the initial studies have indicated a positive result when it comes to turmeric and kidney diseases like PKD.
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.

Black Tea In Your Diet
Speak with your doctor about the appropriate amount of tea for you based on your health history. If you’re pregnant, this is crucial because too much caffeine isn’t good for your unborn baby. Moderation is key when it comes to drinking black tea. Sticking to moderate amounts will help you reap the potential benefits without also suffering the potential side effects. If caffeine is a problem for you, there are decaffeinated versions of black tea that might be more appropriate for your diet.
How Much Black Tea Is Safe
Of course, having a cup of black tea every so often is perfectly safe for most people. Even though black tea contains higher oxalate levels than most teas, its generally not enough to worry about.
One study looked at the amount of oxalates in black tea and found quite low levels. They concluded that drinking 4 cups of black tea would not pose a risk to kidney stones, and for kidney stone patients they recommended not to consume anything with more than 10 mg of oxalate, which is just over two 8oz mugs according to this study .
Whether you can consume black tea with a kidney condition depends on how severe your condition is, how much youre consuming, and your doctors instructions. While most people can drink reasonable amounts of black tea with no problem, be sure to check with your healthcare professional first if you have issues with kidney health.

Top 5 Healthy Drinks For People With Kidney Disease
Many of us love reaching for a refreshing, ice cold drink on a hot summer day, or cozying up with a warm beverage during the dead of winter. But, did you know that the drinks you choose to quench your thirst can have a tremendous impact on your kidney health?
As a nephrologist and Kidney Kitchen® contributor, drink-related questions are some of the most common questions I get. Whether you need to watch out for certain nutrients or have fluid restrictions that you need to stick to, there are ways to enjoy healthy drinks for your kidneys. Remember each person with kidney disease should stick to the food and fluid plan you discussed with your doctor and dietitian, as it addresses your specific kidney function, fluid needs and electrolyte imbalances . Here are five of my favorite drinks that are generally healthy for people with kidney disease:
Ginger & Kidney Stones
No research has been done to see if ginger is good for kidney stones.
Ginger does have a fair amount of oxalate. And, most of that oxalate is soluble, which makes it more absorbable. It is unlikely that eating or cooking with ginger will add a significant amount of oxalate to your diet. But, ginger supplements and extracts might. Id recommend avoiding ginger supplements if you have high urine oxalate.

High Caffeine And Kidneys: Let’s Explore Some Popular Drinks
Unfortunately, the effect of caffeine on the kidneys isnt great. Caffeine consumption is a risk factor for kidney disease, and can cause scarring of the glomeruli – that is, the vessels in the kidneys that filter blood .
Caffeine may also lead to kidney stones, and it increases strain on the kidneys . However, some caffeinated beverages, like coffee, may be safe in small amounts due to certain plant constituents .
One review found that the data is inconclusive regarding caffeine and kidney stone risk however, the researchers pointed out that coffee and decaffeinated coffee,but not other caffeinated beverages, actually had a protective effect on the kidneys .
The bottom line, though, is that you probably shouldnt overdo it when it comes to caffeine. Let’s look at some classically high caffeine drinks: black tea and coffee:
The Amount Of Coffee You Drink
First thing to consider is the nutritional content of coffee. An 8 oz. cup of black coffee has 116 mg of potassium3. This is considered a low potassium food. However, many people drink more than one cup of coffee each day. Three to four cups of coffee a day is considered high in potassium and could raise your potassium levels. Adding creamers or milk can further raise your coffees potassium content. Drinking less than three cups of coffee/day is generally considered safe. Phosphorus, sodium, calories, carbohydrates and protein are minimal in black coffee and not of nutritional consideration.

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.
Best Tea For Kidney Disease
In addition to green tea, there are a couple of other teas that can benefit the kidneys. Some additional best teas for kidney disease include hydrangea and sambong.
Hydrangea is a flowering shrub. According to an animal study published in December 2017 in Frontiers in Pharmacology, extracts from Hydrangea paniculate offered kidney protection to the animals. More human studies are necessary, but this study showed promise.
Sambong is a tropical shrub found in the Philippines and India. One study published in October 2017 in the Asian Journal of Urology found that Blumea balsamifera extract found in sambong reduced the size of crystals in the kidneys. The reduction in size may help prevent kidney stones.
If you have kidney disease, adding hydrangea tea and sambong tea to your beverages along with green tea may increase the benefit you receive. However, be sure to talk to your doctor about adding any herbal teas and supplements first.

Tea: Warm Up With A Cup
For people with chronic kidney disease or end stage renal disease , dietitians are frequently asked if tea is allowed, especially hot tea during cold winter months. As with many foods and drinks we are asked about, the answer is yes! In moderation, tea is a great beverage option that can be healthfully included in a kidney diet. In fact, there are many exciting health benefits that tea offers to anyone.
Teas come from the plant Camellia sinensis, of which the leaves will either turn to black tea with exposure to air or to green tea by steam or heat. Many herbal teas are created from either black or green tea leaves with additions of other herb leaves, spices, flavor extracts, or sweeteners. Some examples are mint, chamomile, or orange blossom herbal teas. You can also find herbal teas that do not contain tea leaves. Read the label to determine when selecting herbal tea. Research on herbal teas is inconsistent, but generally speaking herbal teas from major tea brands are safe for kidney patients to drink.
Tea ranks very high on the oxygen radical absorbency capacity scale, a measure of the antioxidant content of plant-based foods. High ORAC foods and beverages, such as tea, help to fight off free radicals and cancerous cells in the body.
Master Cleanser Lemon Detox Tea
Not all detox programs will allow you to eat other foods in addition to detox teas. An example of this is one of the more common standalone detox teas the master cleanser/lemon detox tea. This diet plan is a 10 day program that consists of replacing all meals with a detox tea containing lemon juice, purified water, cayenne pepper and tree syrup. In this program, you can also drink sea salt water and a mild laxative herbal tea. According to the master cleanser, after 10 days of their detox you will have eliminated toxins from your body, lost weight, and developed glowing skin, shiny hair and strong nails.
What these programs wont tell you is that their regimens are severely lacking in the precious nutrients your body needs. They are also dangerous because they often cause diarrhea which leads to even more nutrient loss and is what contributes to the weight loss seen in those who enroll in these detox tea programs.
So what is the truth? Are detox teas and diets really the toxin elimination problem-solvers they claim to be?

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.
