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

Drinks For Your Kidneys – Coffee and Kidney Disease: The Pros and Cons

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.”

Coffee And Kidney Disease

For a while, coffee was considered potentially detrimental to the Kidneys. However, the relationship may be more complex than originally thought. There have been numerous recent studies on the correlation between coffee consumption and kidney disease, such as a 2008 study performed in Korea that analysed the habits of 2600 women, which showed a decrease in the prevalence of kidney disease.

Another study looked specifically at the Pacific Coast of Nicaragua, where a lower prevalence of chronic kidney disease was found in coffee-growing villages. A 2016 meta-analysis found no association between increased coffee intake and kidney disease in males, and in females, there was a possible reduced risk.

So it seems, contrary to prior thought, that coffee may play a protective role in kidney disease. However, the effectiveness and mechanism are not fully understood. Some believe that the antioxidant effects of coffee may play a part.

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

What Is Decaf Anyway

Decaf coffee may sound like a GMO product with scary connotations attached, but its much simpler than that. The decaffeination of coffee is the process of extracting the caffeine out of normal coffee beans using various different processes, resulting in a tasty, nearly caffeine-free coffee product. There are three main methods of decaffeinating coffee: water processing, direct solvent method, and supercritical carbon dioxide decaffeination method.

The water processing method uses water to flush out the caffeine, making it completely chemical-free. The direct solvent method uses a chemical solvent to extract the caffeine. Finally, the supercritical carbon dioxide decaffeination method uses carbon dioxide as a solvent to extract the caffeine. While each method extracts similar percentages of caffeine, each method has a subtle taste difference.

Although decaf coffee may be processed to get the end result, its important to remember that regular coffee beans are as well. Aside from the slight taste difference, swapping regular coffee for decaf can benefit you in the long run. Whether its due to a doctors recommendation or getting the jitters too often, sometimes decaf coffee is the way to go. And, while you may hear that regular coffee has more benefits, that shouldnt deter you from trying some decaf in the morning. So what are the health benefits of decaf coffee, anyway?

Coffee Metabolites Associated With An Increased Risk Of Ckd

A newly published study highlighted another reason why coffee should be avoided in people with CKD.

Blood metabolites were examined from 4,854 people that identified 20 metabolites associated with coffee consumption. Of these metabolites, two, in particular, are associated with an increased risk of CKD.

O-methylcatechol sulfate and 3-methylcatechol sulfate are xenobiotics involved in benzoate metabolism, both of which have been associated with an increased risk of CKD.

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 exposures of interest were baseline consumption of coffee , tea, and total caffeine intake. Trained dietitians collected participant information about dietary intake through face-to-face interviews using a Spanish version of the validated 143-item SFFQ. Participants reported their average frequency of consumption over the preceding year for a specified serving size of each item. The nine possible answers ranged from never or less than once per month to six or more per day, which were transformed into grams or milliliters per day using the standard portion size of each food and beverage. Two and one items on the FFQ were specifically related to coffee consumption and tea consumption, respectively. The standard serving size of 1 cup of coffee or tea was assigned as 50 mL in the questionnaire. Total coffee consumption was considered as the sum of caffeinated and decaffeinated coffee. Spanish food composition tables were used to estimate daily energy and nutrient intakes.

    Coffee is the most popular drink on the planet, with approximately two billion cups consumed each day. Coffee seeds comprise a variety of minerals, vitamins, caffeine and phytochemicals that can have a myriad of effects on different systems within the body. It’s hardly surprising, therefore, that an area of scientific research has evolved to address the impact of drinking coffee at the molecular level. A “grande” amount of literature exists in this space, with previous studies asking questions such as: Can you really drink too much coffee?

    Is Coffee Good For Your Kidneys

    You may want to think twice before consuming your next cup of joe.

    Scientists from Johns Hopkins Bloomberg School of Public Health are brewing up trouble by claiming coffee drinkers could be at a higher risk of developing chronic kidney disease.

    Their new study, published in the Clinical Journal of the American Society of Nephrology, examined 372 blood metabolites in 3,811 different people. Metabolites are small molecules made or used when the body breaks down food, drugs or chemicals.

    It turns out that 56% of the people who had their blood metabolites examined by the researchers were daily coffee drinkers, and 32% drank more than two cups per day.

    During their examinations, the researchers discovered one coffee-related metabolite that could help kidneys become healthier. However, alarmingly, they also found two other coffee-related metabolites linked to chronic kidney disease.

    Chronic kidney disease, or CKD, involves the gradual loss of kidney function. Damaged kidneys cause toxic waste and extra fluid to accumulate, potentially leading to high blood pressure, heart disease and stroke.

    According to the CDC, about 37 million Americans one in seven adults are estimated to have CKD.

    The new findings surprised Johns Hopkins researchers, given that a report published just six months ago concluded that there was a beneficial effect of coffee on kidney function.

    The Research Team Explains That Increased Caffeine Intake Could Help Your Kidneys Stay Healthy

    The study’s findings uphold some previous research on the connection between caffeine consumption and overall kidney health. The research team explains that caffeine increases urine flow, saying it “represents an important protective factor against the development of kidney stones,” adding that it was still essential to match coffee intake with enough water as well to see this benefit.

    The team also 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.”

    “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,” Kerry Willis, PhD, chief scientific officer for the National Kidney Foundation, said of the findings.

    The balance of salts, minerals, and fluids in our body is regulated in the kidney. However, there are many instances when the masses of salts and minerals become concentrated. It then starts to form a crystal-like stone known as the kidney stones that could be as small as speck but can quickly become quite large. It is accompanied by pain in urination and onset pain on lower back and abdomen.

    The real discomfort comes when stones start to clog the urinary tract it could lead to complications and infection in urinary. At this point, one may experience blood in the urine, fever, chills, vomiting, and nausea. In some cases, surgery is required especially if the stones become large.

    Genetic predisposition and certain medical conditions can trigger kidney stones. A diet high in protein, sodium, and sugar also imposed a risk on the amount of calcium your kidneys can filter that could progress in the development of calcium stones in the kidney. However, the biggest factor that contributes to the development of kidney stones is dehydration. Lack of fluid in the body allows minerals to crystallize and stick, forming a kidney stone.

    Coffee May Be Kind To Your Kidneys

    HealthDay Reporter

    FRIDAY, Nov. 3, 2017 — Can caffeine help people with chronic kidney disease live longer?

    That’s the suggestion of a new study that found that among more than 2,300 Americans with chronic kidney disease, those who drank the most caffeinated drinks reduced their risk of premature death by 24 percent.

    “Our study showed a dose-dependent protective effect of caffeine consumption on all-cause mortality among patients with chronic kidney disease,” said lead researcher Dr. Miguel Bigotte Vieira, from the Centro Hospitalar Lisboa Norte, in Lisbon, Portugal.

    “However, our observational study cannot prove that caffeine reduces the risk of death, but only suggests the possibility of such a protective effect,” he said.

    Moreover, the reasons that caffeine might be protective aren’t clear, and how much caffeine is too little and how much might be too much also isn’t known, Bigotte Vieira added.

    The findings also need to be replicated in a trial that compares caffeine consumption with no caffeine consumption before patients are counseled to drink more coffee or other caffeinated drinks, he noted.

    In the study, the research team found that:

    • those who consumed the least amount of caffeine saw no reduction in death risk,
    • those who had the second higher amount reduced their risk by 12 percent,
    • those who had the third higher amount reduced their risk by 22 percent,
    • and those who consumed the most caffeine reduced their risk by 24 percent.
