Investigations Of Mechanisms Underlying The Preventive Effects Of Caffeine In Kidney Stone Disease

Coffee Causes Kidney Cancer Myth or Reality

It is surprising that, to our knowledge, there was no previous in vitro or in vivo study that examined the effects of caffeine on kidney stone formation until 2016, when in vitro evidence of the protective effects of caffeine on CaOx kidney stone formation was reported . In that study, caffeine was shown to reduce CaOx crystal adhesion on the apical surface of renal tubular epithelial cells by translocation of a CaOx crystal-binding protein, annexin A1, from apical membranes to cytoplasm . This is the only direct evidence that shows cellular mechanisms underlying the inhibitory effects of caffeine against kidney stone disease and strengthens its role as an inhibitor, rather than a promoter, of CaOx kidney stone formation.

What To Drink And Not To Drink To Avoid Kidney Stones

The beverages are the first on the list to be avoided soft drinks, diet cokes. Kidney stones get a trigger with these types of drinks. Coffee, with only 8 oz amount a day, is definitely a yes to drink if having kidney stones. Water is another fluid which helps keep the body hydrated. One glass of orange juice every day is good for the health. But, more than one glass of juice can be problematic. The sufficient amount of liquids in twenty-four hours is favorable enough to keep the kidneys flushed by the frequent urination. Alcohol should be avoided at every cost. Even drinking Beer can increase the risk of developing kidney stones.

Coffee And Genetic Kidney Disease

In the past, basic science studies have indicated that caffeine could increase the risk of growth of kidney cysts in patients with autosomal dominant polycystic kidney disease .

However, in more current clinical studies, consumption of coffee was not noted to be a risk factor for PKD progression.

Ways To Prevent Kidney Stones

Does coffee cause kidney stones? Interestingly, no ...

All that said, there are some always-good-for-you options that can also help prevent stones.

Here’s a short list of recommendations to consider.

  • Fluids of all types are safe, because they increase urine output and that’s a big goal. Dilute urine is your best friend in preventing stones, so drink up.

  • There are benefits to balance, so eat more fruits and vegetables. “I can’t think of a reason why they wouldn’t be safe for anybody,” said Penniston. “A variety of fruits and vegetables can provide stone prevention benefits for most people. There are some foods like fruits and vegetables that, if we eat more of them, can reduce some of the major risk factors of most types of stones.”

  • Bacteria can be a good thing. The gut microbiome is the hottest new topic when it comes to nutrition. And it turns out that the bacteria that live in our GI tract probably do have a lot more to do with our overall health than we think.”Some of the therapy that we do is aimed at optimizing the gut microbiome, and to do that you have to eat foods that will sustain a healthy colonization of bacteria, like fiber and fruits and vegetables,” said Penniston. “Cultured foods like yogurt, and kefir or fermented foods aid the microbiome directly by introducing more bacteria into the digestive tract.”

How The Scientists Explain The Effect Of Coffee On Kidney Stone Formation

The scientists offer a few reasons for why coffee may help reduce the occurrence of kidney stones, noting that caffeine increases urine flow, “which represents an important protective factor against the development of kidney stones,” they said.

They added that caffeine “can also reduce calcium oxalate crystal adhesion to kidney cells,” and that “coffee plants are rich in citric acid urinary citrate is a known inhibitor of renal stone formation.”

Does Coffee Protect The Heart

It’s important to know whether coffee is high in oxalates, because it’s important to take a cup of coffee after another. The answer is, it depends. Coffee can protect the heart with the help of the mitochondria, according to a recent research by the IUF-Leibniz Research Institute in collaboration with IUF-Leibniz University. Coffee lovers report less cases of stone formation than other people, even if their oxalate sensitivity is increasing after having a cup or two of coffee.

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.

Soda Causes Kidney Stones

MYTH BUSTED: While we are tempted to let you believe this one as Soda is a nutrient empty, sugar-laden drink, we must inform you this is NOT the case. The fact is phosphoric acid is the culprit that is an ingredient in SOME sodas, typically colas, and pepper sodas such as Coke or Dr. Pepper and Pepsi. The other issue with Soda is that it is a diuretic because of the caffeine. This makes the salt content in your urine rise, which promotes kidney stones. So have a soda, but also follow it with an equal amount of water and you will decrease that concentrate. Alternatively, you could avoid soda altogether and replace it with healthier alternatives.

Dehydration Effects In The Body From Coffee Drinking

Coffee is the most popular beverage in the world. Coffee beans are roasted and then powdered to make a beverage. The benefits of drinking coffee outweigh the risks, but it has its own benefits as well as risks.

Coffee can cause dehydration due to excess fluid loss, and more so individuals who don’t drink enough water, because of the diuretic effect. It is well known that the chances of developing a stone in your body increase twofold when you are in a dehydrated state. A person who has passed a stone would look for ways to prevent further development of the stone.

Small stones can be easily removed from the system. Bigger stones can cause a painful urination process and the person may experience a lot of urine loss due to incomplete urine voidance. Increased pressure around the surrounding organs and structures of the kidneys can cause pain and make it hard to walk, which is why people experience stones.

Effects Of Caffeine Consumption On Kidney Stone Disease

Do Coffee and Caffeine Cause Kidney Stones?

Although the effects of caffeine on the kidney have been extensively studied, its influence in kidney stone disease seems to be overlooked. The evidence on whether caffeine prevents or promotes kidney stone disease has recently become more clear. Because an increase in fluid intake is widely recommended for the prevention of kidney stone formation, some previous studies during the past 2 decades focused on the relevance of the type of consumed beverages, including caffeinated beverages, in association with kidney stone incidence. In 1996, the first cohort data retrieved from the Health Professionals Follow-Up Study in 45,298 male participants who had no history of kidney stones were reported . The findings showed that not all types of beverages affect kidney stone disease. Only caffeinated coffee and decaffeinated coffee and tea, but not caffeinated and noncaffeinated sodas, are associated with an 10% lower risk of kidney stone incidence .

In 1998, the Nurses Health Study , another cohort study in 81,083 female participants who had no history of kidney stones reported the association between beverage consumption and a lower risk of kidney stone disease . The data showed a 10%, 9%, and 8% lower risk of kidney stone formation in the participants who consumed caffeinated coffee, decaffeinated coffee, and tea, respectively .

New Study Supports Coffee And Caffeine Can Reduce Kidney Stones Risk

A new study using genetic data of hundreds of thousands of people suggests that daily coffee and caffeine consumption can prevent kidney stones.

Coffee and Caffeine Consumption and Risk of Kidney Stones: A Mendelian Randomized Study was published in the National Kidney Foundations American Journal of Kidney Diseases .

Our findings show that going from, for example, one cup a day to 1.5 cups per day, reduces the risk of kidney stones by 40 percent, said co-author of the study, Susanna C. Larsson, PhD, Institute of Environmental Medicine, Karolinska Institute, Stockholm. Our findings strongly suggest that regular coffee consumption reduces the risk of kidney stone formation.

The investigators used data from a total of 571,657 participants with kidney stones from two studies, including 395,044 participants of the U.K. Biobank study and 176,613 participants of another study known as the FinnGen study.

The elegant design of this study, which takes advantage of genetic variants associated with higher coffee and caffeine consumption, strengthens the evidence that coffee and caffeine can prevent kidney stones, said Kerry Willis PhD, NKF Chief Scientific Officer. Given the increasing prevalence of kidney stones in the United States and the associated morbidity, it would be great if this turns out to be a new prevention strategy that is both accessible and affordable.

What Are Kidney Stones

Kidneys work as a filter, cleaning the waste from the blood and creating urine. Sometimes, salt and other minerals that are dissolved in the urine form a crystal and get stuck in our kidney. These formations are called kidney stones. Sizes of stones can range from small as a sugar crystal to as big as a ping pong ball. We rarely notice the presence of a kidney stone until they cause a blockage. When this happens, one can feel an intense pain. It means that kidney stones have traveled into the ureters, the narrow tubes leading to the bladder.

When you have kidney stones, you can feel any of the following symptoms:

  • Severe pain in the back, belly, or groin
  • Frequent or painful urination
  • Blood in the urine
  • Nausea and vomiting

According to National Health Services UK, kidney stones often form when concentrations of minerals in the body become too much and start to build up. The kidney cannot filter all of the waste and some of these minerals stay in the kidney. Kidney stones can be made up of any of the following minerals:

  • calcium
  • ammonia
  • uric acid a waste product produced when the body breaks down food to use as energy
  • cysteine an amino acid that helps to build protein

You and I are prone to developing kidney stones, but the following conditions increase the risk:

It is important to understand the nature and causes of kidney stones. This gives us a clear picture of how kidney stones are developed and whether or not drinking coffee can cause them.
