Can Caffeine Cause Kidney Stones

You Should Avoid Exceeding The Daily Suggested Guidelines For These Two Supplements

Can Energy Drinks Cause Kidney Stones?|Kidney deseases| Very Well

Due to the results of their study, the researchers caution that people should not exceed supplement guidelines suggested by the Institute of Medicine maximum daily levels are 600 to 800 international units of vitamin D and 800 to 1,200 milligrams of calcium.

“It is important to monitor blood and urine calcium levels in people who take these supplements on a long-term basis,” Gallagher said, noting that’s “rarely done in clinical practice.”

Certainly, you’ll want to do what you can to avoid kidney stonesin addition to being painful, they can increase the risk of kidney damage and of developing chronic kidney disease, according to the NKF.

Potassium In Coffee May Prevent Kidney Stones

Coffee and tea are beverages pretty high in potassium. Along with milk and potatoes are the main sources of potassium in the diet of US adults. 1 cup of coffee contains 116 mg of potassium. 1 cup of tea contains 88 mg!

Potassium is a key compound against the forming of kidney stones. Low potassium levels impair calcium reabsorption within the kidneys. So, urinary calcium excretion is increased, causing higher risk of kidney stones!

In a study of over 45,000 men, those who consumed the most potassium had 51% lower risk of forming kidney stones. Moreover, in another study of over 90,000 women, those who consumed about 4,100 mg of potassium a day had 35% lower risk of kidney stones.

Therefore, it seems beneficial to consume lots of foods high in potassium daily. Many fruits, nuts, and seeds are good sources.

The Effect Of Various Drinks And Formation Of Kidney Stones

As a patient suffering from kidney stones, one important fact that you should know is that you should avoid dehydration. You should drink a lot of fluids, especially water, but be cautious with other drinks such as coffee, tea, beer, and wine. Coffee has diuretic properties which increase ones urge to urinate frequently, which can lead to dehydration and finally, kidney stones. Excessive alcohol intake can cause dehydration, which in turn promotes the formation of kidney stone. Tea is also not a good option as it contains oxalate, which is one of the stone-forming compounds. So, if you are at a greater risk of kidney stones, you should keep off tea.

The wittiest thing to do is even if you take the above-mentioned drinks, make sure you also increase your intake of water. Furthermore, water keeps you hydrated. On the bad side, we have sugar-sweetened sodas and colas. These drinks increase the risk of kidney stones and not to mention, they are not healthy at all.

Many Of Us Enjoy Our Morning Cup Of Coffee And Although We May Not Consider Its Effects On Our Health Caffeine Creates Many Changes Throughout The Body But How Does It Affect The Kidneys

Coffee is one of the worlds favourite beverages, and its popularity has spurred interest in the various effects it has on health. However, it seems that coffees relationship to health may be a complex one.

As most people know, the active chemical in coffee is caffeine, which produces various effects, including stimulating the mind and body, increasing blood pressure, and having a diuretic effect on the urinary tract. But does this mean that coffee affects the Kidneys? Well, the short answer is yes, but it might not be as simple as you think.

What Foods And Drinks Cause Kidney Stones

7 Foods that Damage Your Kidneys

Above all, if you have a history of kidney stones avoid consuming foods rich in oxalate, as oxalate binds to calcium forming kidney stones. Spinach, nuts, collard greens, beets, sweet potatoes, rhubarb, legumes, tea, and even chocolate are pretty high in oxalate.

Moreover, consuming animal foods may cause kidney stones, as well. Red meat, poultry, egg, and even seafood increase the levels of uric acid in the body. Uric acid is a byproduct of protein metabolism. Uric acid stones are also a common kidney stone type.

Most noteworthy, avoid excess consumption of salt. Sodium increases the amount of calcium in your urine, causing kidney stones.

Last, but not least, extreme doses of vitamin C from supplements may cause kidney stones, as well. Therefore, prefer to boost your daily vitamin C intake from dietary sources. There are so many foods high in vitamin C. Certainly, a daily dose of 1,000 mg of vitamin C is pretty safe.

What Are Kidney Stones

Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They are quite common with around three in 20 men and up to two in 20 women developing them at some stage of their lives, according to the NHS. Stones can develop in one or both kidneys and most often affect people aged 30 to 60.

Small kidney stones may go undetected and be passed out painlessly in the urine. But its fairly common for a stone to block part of the urinary system which can cause severe pain in the abdomen or groin and sometimes causes a urinary tract infection .

Larger stones may need to be broken up using ultrasound or laser energy. Occasionally, keyhole surgery may be needed to remove very large kidney stones directly.

What Are The Other Foods That Have High Oxalate Content

Generally, black tea has less oxalate content compared to other foods. However, plant sources have high oxalate content because oxalate is bound to calcium to get rid of excess calcium.

When we eat these foods, we will also get oxalate in foods. If we take a high amount from these foods, there is a risk of getting kidney stones.

However, as I mentioned before, most high oxalate foods are also loaded with nutrients such as vegetables and fruits.

It would help if you were careful enough to balance high oxalate fruits and vegetables with low oxalate nutrient-dense foods.

Following is a list of high oxalate foods with their oxalate content

  • Soybean products- 200mg 300mg
  • Almonds – 122 mg
  • Potato 97 mg
  • Beet 152 mg
  • Dates- – 24 mg
  • Raspberries – 48 mg
  • Navy beans 76 mg

You can eat these fruits and vegetables in moderation to have better kidney function.

Yes, cocaine can indirectly cause kidney stones because the drug impacts your bodys fluid level. Your kidneys need a specific amount of fluid to function correctly and prevent kidney stones. Cocaine causes the kidneys to work harder, thus increasing the likelihood that kidney stones develop. Additionally, cocaine use is known to be toxic and can affect kidney health in other ways.

Monitoring The Intake Of High Acid Foods

Harms of black tea-Kidney stones??

Highly acidic urine can increase the risk of uric acid kidney stones and make passing them more painful.

High amounts of acid in the urine also encourage the kidneys to reabsorb citrate rather than excrete it. Citrate is a compound that can help flush out calcium-based stones, as well as impair their growth.

Highly acidic foods include:

According to the National Kidney Foundation, almost 1 in 10 people in the United States develop a kidney stone during their lifetime. The risk is around 19% for men and 9% for women.

Most men experience their first kidney stone after the age of 30 years.

Risk Of Kidney Stones

Beyond medical diseases of the kidney, there are still special situations where intake of coffee might need to be moderated. One such scenario is people who form kidney stones.

Oxalate stones are one of the commonest varieties of kidney stones, and it just so happens that one of the main sources of oxalate in our diet is regular coffee .

Therefore, patients with kidney stones, especially those with calcium oxalate stones, should still regard coffee as a possible risk factor.

Caffeine And Its Popularity

Caffeine is a popular stimulant worldwide that is frequently consumed to enhance mood, alertness, muscle endurance, and exercise performance. Caffeine is a naturally occurring alkaloid found in seeds and leaves of several types of plants . The amount of caffeine content in each plant varies, depending on the type of plant, its growth environment, and the preparation or brewing method. For example, Robusta coffee usually has a higher caffeine content than Arabica coffee . In addition, the roasted temperature and pressure can influence caffeine content in the coffee .

Is Coffee Bad For Kidney Stones

Potatoes and sweet potatoes are potassium-rich vegetables.

Just one medium-sized baked potato contains 610 mg of potassium, whereas one average-sized baked sweet potato contains 541 mg of potassium .

Fortunately, some high potassium foods, including potatoes and sweet potatoes, can be soaked or leached to reduce their potassium contents.

Cutting potatoes into small, thin pieces and boiling them for at least 10 minutes can reduce the potassium content by about 50% .

Potatoes that are soaked in water for at least 4 hours before cooking are proven to have an even lower potassium content than those not soaked before cooking .

This method is known as potassium leaching or the double-cook method.

Although double cooking potatoes lowers the potassium content, its important to remember that their potassium content isnt eliminated by this method.

Considerable amounts of potassium can still be present in double-cooked potatoes, so its best to practice portion control to keep potassium levels in check.


Potatoes and sweet potatoes are high potassium vegetables. Boiling or double cooking potatoes can decrease their potassium content by about 50%.

Tomatoes are another high potassium fruit that may not fit the guidelines of a renal diet.

They can be served raw or stewed and are often used to make sauces.

Just 1 cup of tomato sauce can contain upwards of 900 mg of potassium .

Unfortunately for those on a renal diet, tomatoes are commonly used in many dishes.

Coffee Hypertension And Kidney Disease

As discussed in other articles, high blood pressure is the biggest cause of kidney disease.

There is some evidence that drinking caffeinated coffee could cause a short-lasting increase in blood pressure, with the effects seemingly exaggerated in older patients and people who are not regular drinkers of coffee.

An increase in blood pressure from coffee is seen more frequently in people who already have a history of high blood pressure.

Given this possible link between coffee intake and elevated blood pressure, the concern is often raised about coffee’s ability to cause damage to the kidneys. Despite this plausibility, there is evidence to the contrary.

Data shows that as long as daily consumption of coffee does not exceed 3 to 4 cups , there is no increase in the risk of kidney disease in healthy young subjects.

Chronic Kidney Disease And Diet

Can Kidney Stones Cause Constipation?

From 1990 to 2010, the incidence of Chronic Kidney Disease has doubled. In a review of the standard American diet and its effects on the kidney, the diet appears to have negative effects on human renal function. A decline in renal function was observed in those who consumed an animal protein-rich diet, as compared to those consuming a plant protein-rich diet. Consumption of excessive animal proteins leads to a marked acid load to the kidney, and has been associated with the development of kidney stones. Higher meat consumption leads to increased renal acid excretion and the production of ammonia, which can cause metabolic acidosis and a higher risk for tubulointerstitial injury. In addition to eliminating meat, it is beneficial to add dietary fiber. In a meta-analysis of 14 trials involving 143 participants, the additional dietary fiber significantly reduced serum urea and creatinine levels.

Consumption of animal products impairs renal vascular function, leading to increased inflammation and subsequent microalbuminuria. Studies show that meat ingestion impacts factors such as GFR, glucagon, prostaglandins, and increased albuminuric response. Glomerular hyperfiltration is thought to be due to an inflammatory response via vasodilatory prostaglandins, as a result of animal protein consumption. This is supported by studies showing that the level of hyperfiltration decreases when indomethacin is administered.

Caffeine And Kidney Stones

Caffeine consumption has been linked to kidney stones. Calcium oxalate stones, the most common type of kidney stone, are formed from the combined crystals of calcium and oxalate. In a study reported in the August 2004 “Journal of Urology,” study participants who had a history of calcium kidney stones but normal serum calcium levels were given 6 milligrams of caffeine per kilogram of body weight after fasting for 14 hours. The caffeine increased urinary calcium levels, causing researchers to conclude there was a modest increase in the risk of developing calcium oxalate kidney stones after caffeine consumption.

A person with kidney stones can drink two or fewer 8 oz mugs of black tea drinks. This is because the safe limit of oxalates for kidney stone patients is 10mg or less.

If you have other kidney issues, the amount you can consume depends on your kidney issues severity and the doctors opinions.

If you have any kidney issues, I recommend drinking black tea after discussing it with your healthcare provider.

Assessment Of Caffeine Intake And Other Nutrients

In 1980 , 1986 , and 1991 , participants returned a food-frequency-questionnaire that asked about the average use of > 130 foods, beverages, and supplements in the previous year and dietary information was updated every 4 y. The validity and reliability of the self-reported food-frequency questionnaire were shown in subgroups of the main cohorts . For the present analysis, we used data on intakes of calcium, phosphate, sodium, potassium, magnesium, total fructose, oxalate, phytate, total fluid, and vitamins B-6, C, and D. Except for oxalate, nutrient intakes were calculated from USDA data. The oxalate content of foods was measured by capillary electrophoresis as described elsewhere . The main contributors of caffeine were coffee , tea , and soda . In our nutrient database, we assigned 95 mg caffeine per cup of caffeinated coffee.
